karate run specific feature file

Add Gradle Cucumber Task to build.gradle. Especially since strings can be easily coerced to numbers (and vice-versa) in Javascript, you can combine built-in validators with the self-validation predicate form like this: '#number? [peter] exactly as per design. "arr": [ More examples of Java interop and how to invoke custom code can be found in the section on Calling Java. Use a variable in the called feature instead, for e.g. But in that case you should de-dupe them using a name: And since it is common to run a @setup Scenario only once per-feature you can call karate.setupOnce(). Since asserting against header values in the response is a common task - match header has a special meaning. Changing request body in test script. deleted: false { You can then skip the next few sections, as the pom.xml, recommended directory structure, sample test and JUnit 5 runners - will be created for you. will pause the test execution until a socket connection (even HTTP, currently for web-ui automation only, see. If you are familiar with Cucumber / Gherkin, the big difference here is that you dont need to write extra glue code or Java step definitions ! Learn more. The example below shows the difference between embedded expressions and enclosed JavaScript: So how would you choose between the two approaches to create JSON ? For a detailed discussion on BDD and how Karate relates to Cucumber, please refer to this blog-post: Yes, Karate is not true BDD. My karate config file is calling a feature file which in turn is calling a JAVA file to get the user name of machine to set some conditions. See this for an example. It may be easier for you to use the Karate Maven archetype to create a skeleton project with one command. Instead I get this error. """, # given this invalid input (string instead of number), # but this 'combined form' will fail, which is what we want, # * match date == { month: '#number? name: 'Billie', Only 1 import is needed, and instead of a class-level annotation, you use a nice DRY and fluent-api to express which tests and tags you want to use. Comprehensive support for different flavors of HTTP calls: You can easily choose features and tags to run and compose test-suites in a very flexible manner. id: '#regex[0-9]+', Windows: Ctrl+R+A. 10 How to call custom Java code in karate API tests? This is technically not in the key-value form: multipart field name = 'foo', but logically belongs here in the documentation. The karate-demo has an example showing various ways to configure or set headers: headers.feature. And this example may make it clear why using Karate itself to drive even your UI-tests may be a good idea. Paste the raw json in it and Save it. For example: And similarly for XML and XPath, / represents the response. It gets the value of any Java system-property by name. How to use Karate-config parameters in a feature file? var sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSZ"); You may face issues if you attempt to mix in JS functions or Java code. EDIT: Karate now supports being able to use a line-number, for e.g. Here is an . Refer to the section on XPath Functions for examples of advanced XPath usage. 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. Now, lets continue with the variables in Karate. To make dynamic data-driven testing easier, the following keywords also exist: params, headers, cookies and form fields. If you are looking for a way to do something only once per Feature, take a look at callonce. By now, it should be clear that JsonPath can be very useful for extracting JSON trees out of a given object. And there is no more worrying about Maven profiles and whether the right *.properties file has been copied to the proper place. The karate-chrome Docker is an image created from scratch, using a Java / Maven image as a base and with the following features: Chrome in "full" mode (non-headless) Chrome DevTools protocol exposed on port 9222. _ >= 0', What is even more interesting is that expressions can refer to variables: And functions work as well ! The dry run report is useful to review the tag coverage of what will be run. Run Karate Test. karate.set('temp', squares); Note how even tags to exclude (or include) can be specified: Note that any Feature or Scenario with the special @ignore tag will be skipped by default. You could always do this in two steps: As a convenience, embedded expressions are supported on the Right Hand Side of a match statement even for quoted string literals: And do note that in Karate 1.0 onwards, ES6 string-interpolation within backticks is supported: An alternative to embedded expressions (for JSON only) is to enclose the entire payload within parentheses - which tells Karate to evaluate it as pure JavaScript. response is a built-in variable in karate that stores HTTP API response. The syntax will include a = sign between the key and the value. Karate is an open-source general-purpose test-automation framework that can script calls to HTTP end-points and assert that the JSON or XML responses are as expected. To run only a single scenario, append the line number on which the scenario is defined, de-limited by :. This is a good time to deep-dive into JsonPath, which is perfect for slicing and dicing JSON into manageable chunks. This can be convenient if a particular call results in a huge response payload. Karate can read *.csv files and will auto-convert them to JSON. We can define each scenario with a useful tag. 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. Because Karate strips trailing slashes if part of a path parameter, if you want to append a forward-slash to the end of the URL in the final HTTP request - make sure that the last path is a single /. object.name. } In rare cases you may want to use a csv-file as-is and not auto-convert it to JSON. No tests run in maven project with karate module. Run Test from Command Line. Karate uses LOGBack which looks for a file called logback-test.xml on the classpath. But, you will need runners to run your test cases on the CI/CD pipelines.Here, you can implement the JUnit runner classes and use them to execute your test cases.. Karate will execute all the feature files with the same level and the levels below within the runner class. The csv and yaml types can be initialized in-line using the triple quote or docstring multi-line approach as shown here. karate.appendTo(keys, x); Change the name of the job to "Unit tests" and type the following command: mvn test. For e.g. This capability is triggered when the table consists of a single cell, i.e. Let's have a look over the a very simple and plane gatling script which uses Karate . Refer to this example for more details: graphql.feature. """, """ Step 2: Add feature and scenario description. See also match header which is what you would normally need. Once defined, you can refer to a variable by name. There may be cases where you want to suppress this to make the reports lighter and easier to read. Do look at the documentation and example for configure headers also as it goes hand-in-hand with call. function (customConfigJson, config) { return sdf.format(date); The default is 30000 (30 seconds). Find centralized, trusted content and collaborate around the technologies you use most. Use the classpath: prefix to load from the classpath instead. note that this cannot be dynamic (with in-line variables) so. status: '#number? OR: To run every feature that has either of the @F1 and @F2 tags (runs both) {@F1,@F2}, Combining OR and AND: To run feature that has either of @F1,@F2,@F3 tags but not @F4 tag. When expressing expected results (in JSON or XML) you can mark some fields to be ignored when the match (comparison) is performed. Asking for help, clarification, or responding to other answers. You may have to rely on unit-testing frameworks or integrate additional dependencies. All tests are defined in *.feature files; For every feature file package, you need to have an empty test-class in the same package under src/test/java; Karate recommends to keep the *.feature files in the same folder as the test-class; The <build> section of the pom.xml needs a small tweak for this .. (Similar change needed in build.gradle file) You can over-ride it by using the header keyword before the method step. Name the file as javadsl.java and run using the command: jbang javadsl.java. You can always directly access the variable called responseHeaders if you wanted to do more checks, but you typically wont need to. You can set this up for all subsequent requests or dynamically generate headers for each HTTP request if you configure headers. get metadata about the currently executing feature within a test, functional-style filter operation useful to filter list-like objects (e.g. { In other words, { a: 1, b: null } is considered equal to { a: 1 } and { a: 1, b: '##null' } will match both cases. There is also a variant of Scenario called Scenario Outline along with Examples, useful for data-driven tests. ##(subSchema) So an additional rule in the above flow of rules (before the first step) is as follows: Karate scripts are technically in Gherkin format - but all you need to grok as someone who needs to test web-services are the three sections: Feature, Background and Scenario. A common requirement is to pass dynamic parameter values via the command line, and you can use the karate.properties['some.name'] syntax for getting a system property passed via JVM options in the form -Dsome.name=foo. _ > 0'. """, """ You simply roll your own. Although rarely needed, variable references or expressions are also supported: This is a shortcut to assert the HTTP response code. _ == _$.roomInformation[0].roomPrice' }, """ Variables set using def in the Background will be re-set before every Scenario. Observe how the value of the field being validated (or self) is injected into the underscore expression variable: _. In case you were wondering, variables (and even expressions) are supported on the right-hand-side. First the JavaScript file, basic-auth.js: And heres how it works in a test-script using the header keyword. For performance reasons, you can implement enableForUri() so that this activates only for some URL patterns. The extension of the feature file is " .feature ". Only one JSON argument is allowed, but this does not limit you in any way as you can use any complex JSON structure. A very useful behavior when you combine the optional marker with an embedded expression is as follows: if the embedded expression evaluates to null - the JSON key (or XML element or attribute) will be deleted from the payload (the equivalent of remove). { So if you return complex objects such as a custom Java instance or a JS function that depends on complex objects, this may cause issues when you run in parallel. You can do so by setting the charset to null via the configure keyword: If you need headers to be dynamically generated for each HTTP request, use a JavaScript function with configure headers instead of JSON. Feature: We use it to identify the feature file and give it a small title or a one line definition. Here are some examples: Refer to this file for a comprehensive set of XML examples: xml.feature. But again, you can return a JSON object. This demonstrates a Java Maven + JUnit 5 project set up to test a Spring Boot app. The answer is no. } Any valid JavaScript expression that evaluates to a Truthy or Falsy value is expected after the #?. Also look at the demo examples, especially dynamic-params.feature - to compare the above approach with how the Cucumber Scenario Outline: can be alternatively used for data-driven tests. It is also possible to invoke a feature file via a Java API which can be useful in some test-automation situations. } And JSON arrays would become Java List-s. If you get stuck and ask a question on Stack Overflow, make sure you provide a cURL command that works - or else it would be very difficult for anyone to troubleshoot what you could be doing wrong. When multipart content is involved, the Content-Type header of the HTTP request defaults to multipart/form-data. Since Karate uses Gherkin, you can also employ data-driven techniques such as expressing data-tables in test scripts. The following table summarizes some key differences between Cucumber and Karate. Requirement: Open a feature file in VSCode Editor and ensure a line associated with a test has cursor focus. This is a normal JUnit 4 test class ! function(arg) { all The built-in retry until syntax should suffice for most needs, but if you have some specific needs, this demo example (using JavaScript) should get you up and running: polling.feature. Requirement: Open a feature file in VSCode Editor and ensure editor has focus. Why did Ukraine abstain from the UNHRC vote on China? { "roomInformation": [{ "roomPrice": 679.79}], "totalPrice": 679.79 } The above code reads a template which is in location com/example/templates/idm/idm-create-user-template.json and stores it as a JSON variable called myReq Then we can send the JSON variable to the other feature file using the call method. This can be easily achieved with the following tweak to your maven section. var SimpleDateFormat = Java.type('java.text.SimpleDateFormat'); Provides supports for the Data Driver Testing that is built in-house, hence no need to depend on external frameworks. or anything wrapped in parentheses which will be evaluated as JavaScript - e.g. *.feature files and JavaScript functions. A common use case is to mix API-calls into a larger test-suite, for example a Selenium or WebDriver UI test. 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. You can replace the values of com.mycompany and myproject as per your needs. isValidTime(_)' In real testing scenarios, we can add further checks and validations to the API JSON Response with JsonPath expressions. leagueName: '##string', The first argument to karate.callSingle() is used as the cache key. It is worth taking a few minutes to go through the documentation and examples here: JsonPath Examples. 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.
