karate run specific feature file

We can execute the scenarios in the feature file using maven (which is useful to run the tests in a CI environment) import com. Use this for building multipart named (form) field requests. karate. A special case of embedded expressions can remove a JSON key (or XML element / attribute) if the expression evaluates to null. Also take a look at how a special case of embedded-expressions can remove key-value pairs from a JSON (or XML) payload: Remove if Null. if so, is the configured value a JavaScript function ? So if you really wanted to assert that the HTTP response body is well-formed JSON or XML you can do this: Very rarely used - but you can get the Java system-time (for the current response) at the point when the HTTP request was initiated (the value of System.currentTimeMillis()) which can be used for detailed logging or custom framework / stats calculations. And you can mix API and UI test-automation within the same test script. For JSON and XML files, Karate will evaluate any embedded expressions on load. Because of how easy it is to set HTTP headers, Karate does not provide any special keywords for things like the Accept header. Also note that match contains any is possible for JSON objects as well as JSON arrays. The tests eecutes fine if i use maven command or run from runner file( .java). _ > 0' }, # when validation logic is an 'equality' check, an embedded expression works better, Then match temperature contains { fahrenheit, # when the response is binary (byte-array), # incidentally, match and assert behave exactly the same way for strings, # if b can be present (optional) but should always be null, """ return 'this text will be displayed to the user when they click the rebase button' function (config, downloadLatestFn) { _ == _$.roomInformation[0].roomPrice' }, """ ; OpenAPI Generator that generates: . This is for evaluating arbitrary JavaScript and you are advised to use this only as a last resort ! In most cases you wont need to set the Content-Type header as Karate will automatically do the right thing depending on the data-type of the request. var squares = []; Reading files is achieved using the built-in JavaScript function called read(). They can be very useful in some situations. The following method signatures are available on the karate JS object to obtain a websocket client: These will init a websocket client for the given url and optional subProtocol. How to pass data from one feature file to another in karate? 12341234 each feature opens a new scope without which karate would break in all kinds of ways. { var date = new java.util.Date(); We have verified the run time feature selection api in many possible combination and it is working as expected. Note that you can even include calls to a database from Karate using Java interop. The default setting for the max retry-attempts is 3 with a poll interval of 3000 milliseconds (3 seconds). This behavior where all key-value pairs in the returned map-like object get automatically added as variables - applies to the calling of *.feature files as well. any valid JavaScript expression, and variables can be mixed in, another example: equivalent to the above, JavaScript function invocation, Pretty print the request payload JSON or XML with indenting (default, Pretty print the response payload JSON or XML with indenting (default. The example below shows the difference between embedded expressions and enclosed JavaScript: So how would you choose between the two approaches to create JSON ? Simple arrays of strings or numbers can be stripped of duplicates using karate.distinct(). useful to scrape text out of non-JSON or non-XML text sources such as HTML, like the above, but returns a list of text-matches. Not the answer you're looking for? Use it sparingly, and only for string, number or simple payload comparisons. Else the Runner.path() builder API is the same, refer the description above for JUnit 4. Karate | Test Automation Made Simple. Note that more builder methods are available from the Runner.Builder class such as reportDir() etc. For details of scope and visibility of variables, see Script Structure. squares.push(foo(n)); The scenario expression result is expected to be an array of JSON objects. Karate is the only open-source tool to combine API test-automation, mocks, performance-testing and even UI automation into a single, unified framework. Here is an example JavaScript function that uses some variables in the context (which have been possibly set as the result of a sign-in) to build the Authorization header. In rare cases you may need to set a variable from this routine, and a good example is to make the generated UUID visible to the currently executing script or feature. API tests are written using Behaviour Driven Development (BDD) Gherkin syntax. This is best explained in this example that involves listening to an ActiveMQ / JMS queue. "a": 1, {@F1,@F2,@F3,. Valid options are, The number of bits used to encode each pixel, The maximum size on the smallest dimension before downsampling. $ represents the response. "hotels": [ """, * configure imageComparison = { onShowConfig, # don't embed the image comparison UI when the latest image is the same / similar to the baseline (e.g. english You should take a minute to compare this with the exact same example implemented in REST-assured and TestNG. HTML form fields would be URL-encoded when the HTTP request is submitted (by the method step). Note how JS functions defined at run-time can be mixed with custom Java code to get things done. For example - if a response data element or downloaded file is YAML and you need to use the data in subsequent steps. One way to define test-suites in Karate is to have a JUnit class at a level above (in terms of folder hierarchy) all the *.feature files in your project. You can also pass parameters into the *.feature file being called, and extract variables out of the invocation result. This means that all your. Refer to the demos for another example: soap.feature. Internally, Karate will auto-convert JSON (and even XML) to Java Map objects. You can even perform a conversion from XML to JSON if you want. You can even remove JSON array elements by index. Although rarely needed, variable references or expressions are also supported: This is a shortcut to assert the HTTP response code. Note that this is not the best example of a skeleton Java / Maven project, as it is designed to be . Since a SOAP request needs special handling, this is the only case where the method step is not used to actually fire the request to the server. Step 3: Add steps to run a sample GET API request. """, * def timeLong = call dateStringToLong '2016-12-24T03, # import yaml (will be converted to json), # if the js file evaluates to a function, it can be re-used later using the 'call' keyword (or invoked just like normal js), # the following short-cut is also allowed, # perfect for all those common authentication or 'set up' flows, And request karate.readAsString('classpath, # use only 'ssim' (structural similarity) engine, # always use both 'resemble' and 'ssim' engines but only evaluate the lowest mismatch percentage against our `failureThreshold`, # prefer 'resemble' and fallback to 'ssim' engine only if the resemble mismatch percentage is >= `failureThreshold`, # only consider the comparison as failed when 2% or more pixels are different from the baseline, * configure imageComparison = { failureThreshold, # consider image comparisons that fail due to too many mismatched pixels as passed (especially useful when you are first starting without any baseline images), * configure imageComparison = { mismatchShouldPass, # custom JS function called in Karate HTML image comparison UI when the user clicks the `Rebase` button, """ However, unlike Cucumber, tests arent written in Java and are fully described in the Gherkin file. { You cant do things such as * url 'http://foo.bar' and expect the URL to be set in the called feature. Run Gradle Cucumber Tests from Command Line - QA Automation Expert For example: For Gradle, you must extend the test task to allow the karate.options to be passed to the runtime (otherwise they get consumed by Gradle itself). Karate, BDD, and API Automation - Medium The keywords def, set, match, request and eval take multi-line input as the last argument. Note that the mvn test command only runs test classes that follow the *Test.java naming convention by default. Karate API automation | Cucumber Reporting | Parallel execution - Medium Managing multiple environment configurations in React App - Opcito This is actually the intent most of the time and is convenient. Note that Karate has built-in support for CSV files and here is an example: dynamic-csv.feature. You can add (or over-ride) variables by passing a call argument as shown above. response is a built-in variable in karate that stores HTTP API response. Prefer readability over re-use. if you acquired a string from some external source, or if you generated JSON (or XML) by concatenating text or using replace, you may want to convert a string to JSON and vice-versa. If a few steps in your flow need to temporarily change (or completely bypass) the currently-set header-manipulation scheme, just update configure headers to a new value (or set it to null) in the middle of a script. Given the examples above, it has to be said that a best practice with Karate is to avoid JavaScript for loops as far as possible. Another example is dogs.feature - which actually makes JDBC (database) calls, and since the data returned from the Java code is JSON, the last section of the test is able to use match very effectively for data assertions. A good example of where you may need this is if you programmatically write a file to the target folder, and then you can read it like this: Take a look at the Karate Demos for real-life examples of how you can use files for validating HTTP responses, like this one: read-files.feature. [peter] exactly as per design. "c": 3 In some rare cases where you dont want to auto-convert JSON, XML, YAML or CSV, and just get the raw string content (without having to re-name the file to end with .txt) - you can use the karate.readAsString() API. Response Validation a. status 200 : It will check the status code coming back from the service is 200 b. print Response is: , response : This line of code will print the response from the service in the console. bottom: 893, Note the extra convenience where you dont have to enclose the LHS key in quotes. Do note that when passing JSON, the default Map and List representations should suffice for most needs (see example), and using them would avoid un-necessary string-conversion. Here is an example: You can see the structure of the data here: kittens.json. This is great for testing boundary conditions against a single end-point, with the added bonus that your test becomes even more readable. Like above, but force the SSL algorithm to one of, Whether the HTTP client automatically follows redirects - (default, Set the connect timeout (milliseconds). Getting Started With Karate Test Framework for API - Software That Matters So you can use Karate to set-up data via API calls, then run the UI test-automation, and finally again use Karate to assert that the system-state is as expected. or anything wrapped in parentheses which will be evaluated as JavaScript - e.g. How to change the query variable in WordPress? { This is optional, and Karate will work without the logging config in place, but the default console logging may be too verbose for your needs. For example: And similarly for XML and XPath, / represents the response. Until now, I have shown you run your test cases directly on feature files. Once you get a result, you typically use it to set global variables. Things will work even if the karate-config.js file is not present. In rare cases you may want to use a csv-file as-is and not auto-convert it to JSON. predicate syntax, and situations where this comes in useful will be apparent when we discuss match each. time: '#? Also note that you dont use @Karate.Test for the method, and you just use the normal JUnit 5 @Test annotation. Key Features (click images to expand) Monitors hundreds of thousands of threads running concurrently on each GPU. multipart file uploads can be tricky, and hard to get right. Now, lets continue with the variables in Karate. The JavaScript interpreter will try to convert types across Java and JavaScript as smartly as possible. It is worth taking a few minutes to go through the documentation and examples here: JsonPath Examples. This is best explained in this example: copy.feature. } Here is an example which also demonstrates how you could assert for expected values in the response XML. Since replace auto-converts the result to a string, make sure you perform type conversion back to JSON (or XML) if applicable. When you have a runner class in place, it would be possible to run it from the command-line as well. This approach can certainly enable product-owners or domain-experts who are not programmer-folk, to review, and even collaborate on test-scenarios and scripts. Karate also has built-in support for websocket that is based on the async capability and the listen keyword. It consists of the diamond-shaped Singapore Island and some 60 small islets; the main island occupies all but about 18 square miles of this combined area. Normally we recommend that you keep your re-usable features lightweight - by limiting them to just one Scenario. Any Karate expression can be used in the cell expression, and you can even use Java-interop to use external data-sources such as a database. UI for debugging the Test. If you find yourself struggling to write dynamic JsonPath filters, look at karate.filter() as an alternative, described just below. Here are some examples: Now that we have seen how JSON is a native data type that Karate understands, there is a very nice way to create JSON using Cucumbers support for expressing data-tables. There is also a karate.mapWithKey() for a common need - which is to convert an array of primitives into an array of objects, which is the form that data driven features expect. Normally in dev mode, you will use your IDE to run a *.feature file directly or via the companion runner JUnit Java class. And if you need multiple functions, you can easily organize them into a single Java class with multiple static methods. Use the comma-delimited form (see above) or the JS helper (see below). For example a lot of Java projects directly (or indirectly) depend on Netty or Thymeleaf or ANTLR, etc. It is worth pointing out that JSON is a first class citizen of the syntax such that you can express payload and expected data without having to use double-quotes and without having to enclose JSON field names in quotes. You can replace the values of com.mycompany and myproject as per your needs. Note that you would typically want to use the @ignore tag for such cases. As a short-cut, when running JsonPath expressions - $ represents the response. karate | Multiple Scenarios in a single feature - YouTube path to file containing the trust chain for your server certificate. What this means is that you are free to use whatever makes sense for you. Important: If you attempt to build a URL in the form ?myparam=value by using path the ? You can feed an Examples table from a custom data-source, which is great for those situations where the table-content is dynamically resolved at run-time. Add Gradle Cucumber Task to build.gradle. You can even use a regular-expression so that instead of checking for equality, Karate will just validate that the actual value conforms to the expected pattern. You can always directly access the variable called responseHeaders if you wanted to do more checks, but you typically wont need to. See the section on reading files - and also this example dynamic-csv.feature, which shows off the convenience of dynamic Scenario Outline-s. If you want, you could even create nested chunks of JSON that name-space your config variables. The function is expected to return a JSON object and all keys and values in that JSON object will be made available as script variables. And any variables which are alive in the context can be used in this expression. Use a variable in the called feature instead, for e.g. Setting values on JSON documents is simple using the set keyword. In This video explained how to set up the runner class so that the parallel execution is possible Follow me on LlinkedIn - https://www.linkedin.com/in/krishn. Here is a summary of what the different shapes mean in Karate: There is no need to prefix variable names with $ on the left-hand-side of match statements because it is implied. sorts the list using the provided custom function called for each item in the list (and the optional second argument is the item index) e.g. Load testing. convenient way to execute an OS specific command and return the console output e.g. Selecting Features/Scenarios at run time based on external data You need to use karate.toJava() to wrap JS functions passed to custom Java code. And as a testing framework, Karate discourages tests that give different results on every run. Here is a recap of symbols that can be used in JSON embedded expressions: There is a shortcut for match each explained in the next section that can be quite useful, especially for in-line schema-like validations. Now I can dynamically able to select the list of features at run time :) Regarding the karate.abort() Now the result for the particular step is marked as 'SKIPPED', but the results for the steps below it still shown as 'PASSED'. Modifying existing JSON and XML is natively supported by Karate via the set keyword, and replace is primarily intended for dealing with raw strings. Open a feature file after you have installed the plug-in. #12 - Test Runner in Karate Junit5 || Run Feature Files from Maven By default, Karate will load all *.feature files from sub-directories as well. or $[. Refer to conditional logic for more ideas. So in dev mode you can easily set this behavior like this. It begins with the Feature keyword, followed by the . How to configure karate to stop execution when any scenario fails? Heres thearticle. You dont have to compile code. Open the command prompt and change the directory to the project location where pom.xml is present. You also have the option of setting multiple cookies in one-step using the cookies keyword. right: 1496 """, # optional (can be null) and if present should be an array of size greater than zero, # should be an array of size equal to $.count, # use a predicate function to validate each array element, # if you prefer using 'pure' JsonPath, you can do this, # using the karate object if the expression is dynamic, """ And the JSON will still be well-formed, and editable in your IDE or text-editor. Can be expressions that will be evaluated. The match keyword is explained later, but it should be clear right away how convenient the table keyword is. There are examples of calling JVM classes in the section on Java Interop and in the file-upload demo. The match keyword can be made to iterate over all elements in a JSON array using the each modifier. For a proxy that requires authentication, set the, The charset that will be sent in the request, HTTP requests and responses (including headers) will appear in the HTML report, default. Here is an example of performing a configure driver step in JavaScript: By default, Karate will add logs to the report output so that HTTP requests and responses appear in-line in the HTML reports. Click on Run the Workflow and Start. Testing a Java Spring Boot REST API with Karate - Semaphore The syntax will include a = sign between the key and the value. In fact, this is the mechanism used when karate-config.js is processed on start-up. name: John ##(subSchema) Each functionality of the software must have a separate feature file. object.name. Karate Gatling | Karate A good example is when you have the expected data available as ready-made JSON but it is in a different shape from the actual data or HTTP response. Karate-config.js, Is it possible to run java method after every karate scenario? Since multiple values are supported, you can also do this: A little-known capability of the Cucumber / Gherkin syntax is to be able to tag even specific rows in a bunch of examples ! Also note that you can run a scenario by name, for e.g. ] Observe how you can match the result of a JsonPath expression with your expected data. One pattern you can adopt is to create a factory method that returns a Java function - where you can easily delegate to the logic you want. Once defined, you can refer to a variable by name. Heres a reminder that running any single JUnit test via Maven can be done by: Where CatsRunner is the JUnit class name (in any package) you wish to run. As well as being a great voice for video games, animation and films, I've now added MoCap training to my bow - and am currently in full Motion Capture training with the Mocap Vaults. {}, """ See also match header which is what you would normally need. Since the eval keyword can be omitted when operating on variables using JavaScript, this leads to very concise code: Refer to eval for more / advanced examples. This comes in useful because depending on how you organize your files and folders - you can have multiple feature files executed by a single JUnit test-class. Soumendra Daas has created a nice example and guide that you can use as a reference here: hello-karate. You can find more examples here: xml.feature. "a": 1, So the only way to call this Scenario is by using the karate.setup() JS API. Keywords such as set and remove allow you to to tweak payload-data to fit the scenario under test. You can use print to log variables to the console in the middle of a script. The argument can be provided after the function name, without parentheses, which makes things slightly more readable (and less cluttered) especially when the solitary argument is JSON. The last row in the table is a little different from the rest, and this short-cut form is the recommended way to validate the length of a JSON array. Notice that in the above example, string values within the table need to be enclosed in quotes. If you want to dynamically and programmatically determine the tags and features to be included - the API also accepts. Assertions and HTML reports are built-in, and you can run tests in parallel for speed. Refer to this demo feature for an example: kitten-create.feature. 3 Day Blinds is the leading manufacturer and retailer . How do you pass special characters in karate URL? Create a Test Runner class. Also note that multipart file takes a JSON argument so that you can easily set the filename and the contentType (mime-type) in one step. How do you find the longest decreasing subsequence of a sequence? Do new devs get fired if they can't solve a certain bug? The function has to return a JSON object. Also see first.feature and second.feature in the demos. This is what is normally expected and simulates a web-browser - which makes it easy to script things like HTML-form based authentication into test-flows. Or - if a call is made without an assignment, and if the function returns a map-like object, it will add each key-value pair returned as a new variable into the execution context. Default value is, Skip comparison for this field even if the data element or JSON key is present, Expects actual (string) value to conform to the UUID format, Expects actual (string) value to match the regular-expression STR (see examples above), Expects the JavaScript expression EXPR to evaluate to true, see, The parent of self or current item in the list, relevant when using, useful to create lists out of items (which can be lists as well), see, useful to append to a list-like variable (that has to exist) in scope, see, returns only unique items out of an array of strings or numbers, embeds the object (can be raw bytes or an image) into the JSON report output, see this, gets the value (read-only) of the environment property karate.env, and this is typically used for bootstrapping, for really advanced needs, you can programmatically generate a snippet of JavaScript which can be evaluated at run-time, you can find an example. You can define the variables with the def keyword in the feature file directly. And there is another example in the karate-demos: schema.feature where you can compare Karates approach with an actual JSON-schema example. 30 Animations - 15 WALK STYLES - LONG AND LOOPED VERSIONS - 60 Total Animation Files. Here is an example: Here above, you see the karate.log(), karate.env and karate.configure() helpers being used. Calling a feature file from another file. #string Format of the keyStore file. auth tokens) only once for all of your tests. If you are looking for a way to do something only once per Feature, take a look at callonce. Here is an example of what is possible: Not something you would commonly use, but in some cases you need to disable Karates default behavior of attempting to parse anything that looks like JSON (or XML) when using multi-line / string expressions. Since this is a frequently asked question, the different ways of being able to re-use code (or data) are summarized below. Run Test Cases In Parallel & Generate Reports Using Karate Tool To run a script *. This is a problem especially for expensive, time-consuming HTTP calls, and this has been an open issue for a long time. Since the karate object is injected within karate-config.js on start-up, it is a simple and effective way for other processes within the same JVM to pass configuration values to Karate at run-time. You can use callonce instead of call within the Background in case you have multiple Scenario sections or Examples. Also refer to the wiki for using Karate with Gradle. You can re-use the function you create across your whole project. This is a good time to deep-dive into JsonPath, which is perfect for slicing and dicing JSON into manageable chunks. The specific value here varies from request to request, so check the response value using Fuzzy Matching provided by Karate. But, unlike Cucumber, the steps do not require a . ZenWave Karate IDE - Visual Studio Marketplace Other errors could be a java.net.URISyntaxException and match not working as expected because of special or foreign characters, e.g. """, * configure imageComparison = { onShowRebase, # custom JS function called in Karate HTML image comparison UI when the user clicks the `Show config` button, """ For some more examples check test-outline-name-js.feature. Valid options are, Resemble option to ignore a specific color, Resemble option to override preset tolerances for color and brightness, SSIM grayscale algorithm. Use the classpath: prefix to load from the classpath instead. For suppressing sensitive information such as secrets and passwords from the log and reports, see Log Masking and Report Verbosity. Karate - How to run a specific scenario only in one environment? Refer to this case study for how dramatic the reduction of lines of code can be. And since header names are case-insensitive - it ignores the case when finding the header to match. Karate supports JUnit 5 and the advantage is that you can have multiple methods in a test-class. Though not really recommended, you can have multiple Scenario-s within a Feature tagged with @setup. This is a very powerful way to generate test-data without having to load a large number of data rows into memory. For convenience, some stats are logged to the console when execution completes, which should look something like this: The parallel runner will always run Feature-s in parallel. Notice how once the authToken variable is initialized, it is used by the above function to generate headers for every HTTP call made as part of the test flow. but if you want to run only a specific feature file from a JUnit test even if there are multiple *.feature files in the same folder . if an API needs to be called to get a JSON array, you can call a separate Scenario to set up this data. } Note that a single JS function is sufficient to transform a given JSON object into a completely new one, and you can use complex conditional logic if needed. match each can be combined with contains deep so that for each JSON object a deep contains match is performed within nested lists or objects. Another example for a popular Maven reporting plugin that is compatible with Karate JSON is Cluecumber. } This is useful when you want to express a one-off lengthy snippet of text in-line, without having to split it out into a separate file. Before we get to the HTTP keywords, it is worth doing a recap of the various shapes that the right-hand-side of an assignment statement can take: They are url, path, request, method and status.
