Passing data from one feature file to another is very common requirement when it comes to automation. But normally a match statement is preferred unless you want a really descriptive error message. REST-style path parameters. . What are the features of a Karate test script? Here is an example of how to get the current date, and formatted the way you want: And the above will result in something like this being logged: [print] 2017/10/16. 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. Karate provides an elegant native-like experience for placeholder substitution within strings or text content. Another example for a popular Maven reporting plugin that is compatible with Karate JSON is Cluecumber. Bloating your configuration can lead to loss of performance, and maintainability may suffer. function (customConfigJson, config) { Scenario: creating a repo and verifying the response * path '/user/repos' #Change the repo_name . Refer to this example for more details: graphql.feature. countryId: '#number', But this time, the return value from the call step will be a JSON array of the same size as the input array. Karate is quite flexible, and provides multiple options for you to evolve patterns that fit your environment, as you can see here: xml.feature. For example, here below is an actual report generated by the cucumber-reporting open-source library. Observe how the value of the field being validated (or self) is injected into the underscore expression variable: _. If needed, this can be changed by using configure - any time during a test, or set globally via karate-config.js. Do note that if you prefer a pure Java API - Karate has that covered, and with far more capabilities. The default is 30000 (30 seconds). each feature opens a new scope without which karate would break in all kinds of ways. Paste the raw json in it and Save it. If you want to keep the level as DEBUG (for HTML reports) but suppress logging to the console, you can comment out the STDOUT root appender-ref: Or another option is to use a ThresholdFilter, so you still see critical logs on the console: If you want to exclude the logs from your CI/CD pipeline but keep them in the execution of your users in their locals you can configure your logback using Janino. note the wildcard '*' in the JsonPath (returns an array), # when inspecting a json array, 'contains' just checks if the expected items exist, # and the size and order of the actual array does not matter, # the .. operator is great because it matches nodes at any depth in the JSON "tree". ] For example - if a response data element or downloaded file is YAML and you need to use the data in subsequent steps. Also note that you dont use @Karate.Test for the method, and you just use the normal JUnit 5 @Test annotation. And the JSON will still be well-formed, and editable in your IDE or text-editor. Install Karate VS Code Plugin. will pause the test execution until a socket connection (even HTTP, currently for web-ui automation only, see. The approach in this section is more suited for troubleshooting in dev-mode, using your IDE. You can use karate.callSingle() directly in a *.feature file, but it logically fits better in the global bootstrap. However, unlike Cucumber, tests arent written in Java and are fully described in the Gherkin file. Any valid JavaScript expression that evaluates to a Truthy or Falsy value is expected after the #?. 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 ! Defining the request is mandatory if you are using an HTTP method that expects a body such as post. If you face issues such as class not found, just pull in the karate-core dependency, and use the all classifier in your pom.xml (or build.gradle). Note that it is a map of lists so you will need to do things like this: And just as in the responseCookies example above, you can use match to run complex validations on the responseHeaders. It is actually a transpose of the table approach, and can be very convenient when there are a large number of keys per row or if the nesting is complex. In This video explained how to call one feature file from another feature file by using the call and read functions. // so now the txid_header would be a unique uuid for each request, // hard coded here, but also can be as dynamic as you want, // use the 'karate' helper to do a 'safe' get of a 'dynamic' variable, // the 'appId' variable here is expected to have been set via karate-config.js (bootstrap init) and will never change, # second HTTP call, to get a list of 'projects', # if foo is not defined, it will default to 42. Since match and set go well together, they are both introduced in the examples in the section below. There is no concept of a default where for e.g. 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. bottom: 893, Here is an example of an implementation. return 'this text will be displayed above the image comparison config\n' + customConfigJson This comes in useful . 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. The following parameters are supported: For end-to-end examples in the Karate demos, look at the files in this folder. if there is no matching tag - that the Examples without a tag will be executed. All feature files should be in src/test/resources and create the Cucumber Runner class as CucumberRunnerTest. Karate is built on top of Cucumber, another BDD testing framework, and shares some of the same concepts. The short cut $variableName form is also supported. 'put', # if you have dynamic keys you can do this, # enable ssl (and no certificate is required), # enable ssl and force the algorithm to TLSv1.2, # time-out if the response is not received within 10 seconds (after the connection is established), # set the uri of the http proxy server to use, https://user:password@zalenium.net/wd/hub, # if this was in karate-config.js, it would apply "globally", # enable X509 certificate authentication with PKCS12 file 'certstore.pfx' and password 'certpassword', # trust all server certificates, in the feature file, // trust all server certificates, global configuration in 'karate-config.js', # add new keys. Difficulties with estimation of epsilon-delta limit proof. {2}', id: '#uuid' }, # convenient (and recommended) way to check for array length, # here we enclose in round-brackets to preserve the optional embedded expression, # so that it can be used later in a "match", """ Here is an example that combines the table keyword with calling a *.feature. The problem is, I want to use other config values as shown here but when I run the test, it fails to access config.ApiKey correctly. Refer to the documentation for cookie for details and how you can disable this if need be. But this does not limit you in any way, because similar to how you can call *.feature files, you can pass a whole JSON object as the argument. Conditionally making a test fail is easy with karate.fail(). Do new devs get fired if they can't solve a certain bug? The name of the class doesnt matter, and it will automatically run any *. You can get really creative and use JS functions to filter data for different needs. Given this custom, user-defined Java class: This is how it can be called from a test-script via JavaScript, and yes, even static methods can be invoked: Note that JSON gets auto-converted to Map (or List) when making the cross-over to Java. 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. A stand-alone example can be found here: examples/image-comparison along with a video explanation. Anyway, there are times when you may want to force integers (perhaps for cosmetic reasons) and you can easily do so using the double-tilde short-cut: ~~. Karate has a set of Java API-s that expose the HTTP, JSON, data-assertion and UI automation capabilities. Making statements based on opinion; back them up with references or personal experience. returns the operating system details as JSON, for e.g. In situations where you start an (embedded) application server as part of the test set-up phase, a typical challenge is that the HTTP port may be determined at run-time. The structure should be a def keyword followed by a variable name and a value. Things will work even if the karate-config.js file is not present. Refer to this demo feature for an example: kitten-create.feature. Refer to the demo karate-config.js for an example and how the demo.server.port system-property is set-up in the test runner: TestBase.java. One extra convenience for JSON is that if the variable itself (which was cat in the above example) does not exist, it will be created automatically. But again, you can return a JSON object. While $ always refers to the JSON root, note the use of _$ above to represent the current node of a match each iteration. { Create a new job using the +Add new job link. Billie,LOL Ideally you should return only pure JSON data (or a primitive string, number etc.). For JSON and XML files, Karate will evaluate any embedded expressions on load. And as shown in the example below, having text in-line is useful especially when you use the Scenario Outline: and Examples: for data-driven tests involving Cucumber-style place-holder substitutions in strings. This mechanism works by calling configure cookies behind the scenes and if you need to stop auto-adding cookies for future requests, just do this: Also refer to the built-in variable responseCookies for how you can access and perform assertions on cookie data values. This provides the following methods: In any complex testing endeavor, you would find yourself needing common code that needs to be re-used across multiple test scripts. For example a lot of Java projects directly (or indirectly) depend on Netty or Thymeleaf or ANTLR, etc. For example: And if you need to suppress placeholder substitution for read(), but still need a JSON snippet, you can do this. Note the extra convenience where you dont have to enclose the LHS key in quotes. So how can you get this value injected into the Karate configuration ? They can be very useful in some situations. 1. cd C:\Users\Vibha\eclipse-workspace-test\demo. Other options are the quickstart or the standalone executable. Important: do not use the @RunWith(Karate.class) annotation. Also see first.feature and second.feature in the demos. Name the file as javadsl.java and run using the command: jbang javadsl.java. Karate uses LOGBack which looks for a file called logback-test.xml on the classpath. "a": 1, This can be convenient if a particular call results in a huge response payload. This report is useful for troubleshooting and debugging a test because all requests and responses are shown in-line with the steps, along with error messages and the output of print statements. This is very useful to boil-down those common steps that you may have to perform at the start of multiple test-scripts - into one-liners. Paste the raw data in textbox. This will always hold the contents of the response as a byte-array. } # and even ignore fields at the same time ! Since paths are expected at the end of the command-line options - if you want to only over-ride tags, use the = sign to make argument values clear. Use the classpath: prefix to load from the classpath instead. You could use it for hard-coded absolute paths in dev mode, but is obviously not recommended for CI test-suites. request can have the 'Authorization' header set in a way that the server expects. Once you have a JSON or XML object, Karate provides multiple ways to manipulate, extract or transform data. 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. You can always use a JavaScript switch case within an eval or function block. That feeling when: REMINDER: The latest NVIDIA drivers disable the LHR unlock system. Staging Ground Beta 1 Recap, and Reviewers needed for Beta 2. As a convenience, cookies from the previous response are collected and passed as-is as part of the next HTTP request. Because of how easy it is to set HTTP headers, Karate does not provide any special keywords for things like the Accept header. You can use callonce instead of call within the Background in case you have multiple Scenario sections or Examples. Expect to spend $20 to $45 per square foot for a custom job. When you use Karate, all your data assertions can be done in pure JSON and without needing a thick forest of companion Java objects. And there is no more worrying about Maven profiles and whether the right *.properties file has been copied to the proper place. lastUpdated: { on: "#ignore" }, 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. 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. After you define the URL, you need to define a path to send a request. Note how we unpack the kittens and use it to data drive the Scenario Outline. A Java API also exists for those who prefer to programmatically integrate Karates rich automation and data-assertion capabilities. This is great for testing boundary conditions against a single end-point, with the added bonus that your test becomes even more readable. You can always use a JavaScript function or call Java for more complex logic. You can choose between the string-placeholder style or directly refer to the variable foo (or even the whole row JSON as __row) in JSON-friendly expressions. var foo = function(v){ return v * v }; You can also re-use other *.feature files from test-scripts: When a called feature depends on some side-by-side resources such as JSON or JS files, you can use the this: prefix to ensure that relative paths work correctly - because by default Karate calculates relative paths from the root feature or the top-most caller. This means that as long as the token on file is valid, you can save time by not having to make the one or two HTTP calls needed to sign-in or create throw-away users in your SSO store. And if you need multiple functions, you can easily organize them into a single Java class with multiple static methods. Since asserting against header values in the response is a common task - match header has a special meaning. This is best explained in this example: copy.feature. Read the documentation of the stand-alone JAR for more - such as how you can even install custom command-line applications using jbang ! For Gradle, you simply specify the test which is to be include-d: The big drawback of the approach above is that you cannot run tests in parallel. 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. 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. In typical frameworks it could mean changing multiple properties files, maven profiles and placeholders, and maybe even threading the value via a dependency-injection framework - before you can even access the value within your test. So you get the picture, any kind of complicated sign-in flow can be scripted and re-used. } Karate Tests you can immediately run, with validation, inline payload examples and . Another good thing that Karate inherits is the nice IDE support for Cucumber that IntelliJ and Eclipse have. """, Then match each json.hotels contains { totalPrice, #? You cant do things such as * url 'http://foo.bar' and expect the URL to be set in the called feature. You can easily do this via karate.set('someVarName', value). if you want to conditionally stop a test with a descriptive error message, e.g. 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. An image comparison UI will also be embedded into the Karate HTML report with detailed information about any differences between the two images. This is actually the intent most of the time and is convenient. Also note that you can run a scenario by name, for e.g. The BDD syntax popularized by Cucumber is language-neutral, and easy for even non-programmers. And yes, variables can come from global config. If you really need to re-use a Java function, see Java Function References. You could even have all the steps start with When and Karate wont care. In real-life scripts, you would typically also use this capability of Karate to configure headers where the specified JavaScript function uses the variables that result from a sign in to manipulate headers for all subsequent HTTP requests. Since templates can be loaded using the classpath: prefix, you can even re-use templates across your projects via Java JAR files. A good example is when you want to use a CSV file as the request-body for a file-upload. Note that if you tag Examples like this, and if a tag selector is used when running a given Feature - only the Examples that match the tag selector will be executed. Just like yaml, you may occasionally need to convert a string which happens to be in CSV form into JSON, and this can be done via the csv keyword. The @setup tag is built-in for this purpose and any Scenario tagged with this will behave like @ignore. This can be really convenient, for example to never run some tests in a certain production like or sensitive environment. Open a feature file after you have installed the plug-in. The above would result in a URL like: http://myhost/mypath?someKey=hello&anotherKey=foo. path to file containing public and private keys for your client certificate. 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. You can skip this section and jump straight to the Syntax Guide if you are in a hurry to get started with Karate. So you can refer to the response, responseStatus or even responseHeaders if needed. "a": 1, or is the configured value a JSON object ? 2. Also see the option below, where you can data-drive an Examples: table using JSON. Since these are tests and not production Java code, you dont need to be bound by the com.mycompany.foo.bar convention and the un-necessary explosion of sub-folders that ensues. Parallel testing is the core functionality that is provided by the Karate itself, hence we need not depend on Maven, Gradle, etc. Now it should be clear how Karate makes it easy to express JSON or XML. A feature file is usually a common file which stores feature, scenarios, and feature description to be tested. The .graphql and .gql extensions are also recognized (for GraphQL) but are handled the same way as .txt and treated as a string. ] c ; OpenAPI Generator that generates: . 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. { 5678 And since header names are case-insensitive - it ignores the case when finding the header to match. for simulating check-boxes and multi-selects): You can also dynamically set multiple fields in one step using the form fields keyword. There can be multiple Scenario-s in a *.feature file, and at least one should be present. 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. #karate #junit5This video explain how you can call one scenario from another scenario from the same features files as well as from another feature file This is technically not in the key-value form: multipart field name = 'foo', but logically belongs here in the documentation. You dont have to compile code. Multi-value headers (though rarely used in the wild) are also supported: Also look at the headers keyword which uses JSON and makes some kinds of dynamic data-driven testing easier. Does ZnSO4 + H2 at high pressure reverses to Zn + H2SO4? Refer to conditional logic for more ideas. The assert keyword can be used to assert that an expression returns a boolean value. The most important feature of Karate isno coding. Both the official Visual Studio Code and IntelliJ plugins support step-through debugging of Karate tests. But, unlike Cucumber, the steps do not require a . This enables more concise tests, and the file can be re-usable in multiple, data-driven tests. Then we can run the mem_report helper function to check the used/available GPU statistics. Prefer readability over re-use. This approach is indeed slightly more complicated than traditional *.properties files - but you need this complexity. Karate report & karate log to have scenario name with test data. predicate syntax, and situations where this comes in useful will be apparent when we discuss match each. The Hello World is a great example of REST-ful use of the url when the test focuses on a single REST resource. It short-cuts to the pre-defined variable responseHeaders and reduces some complexity - because strictly, HTTP headers are a multi-valued map or a map of lists - the Java-speak equivalent being Map>. status: '#number? Once defined, you can refer to a variable by name. Karate also has built-in support for websocket that is based on the async capability and the listen keyword. } On the other hand, if you are expecting a variable in the Background to be modified by one Scenario so that later ones can see the updated value - that is not how you should think of them, and you should combine your flow into one scenario. Theres also a cross-platform stand-alone executable for teams not comfortable with Java. 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.
