The first option using shared scope should be fine for most projects, but if you want to name space your functions, use isolated scope: You can even move commonly used routines into karate-config.js which means that they become global. Observe how the get shortcut is used to distill the result array of variable envelopes into an array consisting only of response payloads. But, unlike Cucumber, the steps do not require a . The function argument is the row-index, so you can easily determine when to stop the generation of data. So now, complex payloads (that include arrays) can easily be validated in one step by combining validation markers like so: Especially note the re-use of the oddSchema both as an embedded-expression and as an array validation (on the last line). How do you find the longest decreasing subsequence of a sequence? Now, run the TestRunner and observe that you would not find all the verbose logs in console which you were getting before and rather it would be saved in a file karate.log under target folder . Raw Blame. For every HTTP request made from Karate, the internal flow is as follows: This makes setting up of complex authentication schemes for your test-flows really easy. The retry keyword is designed to extend the existing method syntax (and should appear before a method step) like so: Any JavaScript expression that uses any variable in scope can be placed after the retry until part. *.feature files and JavaScript functions. In real testing scenarios, we can add further checks and validations to the API JSON Response with JsonPath expressions. In This video explained how to call one feature file from another feature file by using the call and read functions. if the name is "first": And if you use IntelliJ - you can right click and do the above. The not equals operator != works as you would expect: You typically will never need to use the != (not-equals) operator ! Refer to karate.tags and karate.tagValues. But one pattern that you should be aware of is that JSON is actually a great data-structure for looking up data. This is a sample Spring Boot web-application that exposes some functionality as web-service end-points. """, * configure imageComparison = { onShowRebase, # custom JS function called in Karate HTML image comparison UI when the user clicks the `Show config` button, """ A stand-alone example can be found here: examples/image-comparison along with a video explanation. Ex- headers. * url myUrl. count: '#number', REST API request testing. return 'this text will be displayed to the user when they click the rebase button' A typical need would be to perform a sign in, or create a fresh user as a pre-requisite for the scenarios being tested. If you dont pass a handler (or it is null), the first message is returned. Here is an example of an implementation. Ideally it should return pure JSON and note that you always get a deep clone of the cached result object. Karate provides its own DSL (Domain Specific Language), which uses a Gherkin-like language enabling one to write tests without programming knowledge, and write tests in .feature files. 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. This approach is indeed slightly more complicated than traditional *.properties files - but you need this complexity. But when you deal with complex, nested JSON (or XML) - it may be easier in some cases to use replace, especially when you want to substitute multiple placeholders with one value, and when you dont need array manipulation. If you use the above config, logs will be captured in target/karate.log. Type the following commands: mvn spring-boot:run & mvn test -Dtest=KarateTests. Use it sparingly, and only for string, number or simple payload comparisons. 1. Short story taking place on a toroidal planet or moon involving flying, Doesn't analytically integrate sensibly let alone correctly, Full text of the 'Sri Mahalakshmi Dhyanam & Stotram', Equation alignment in aligned environment not working properly. bar: 'world' Calling any Java code is that easy. Modifying existing JSON and XML is natively supported by Karate via the set keyword, and replace is primarily intended for dealing with raw strings. JSON arrays), see, convenient for the common case of transforming an array of primitives into an array of objects, see, useful to merge the key-values of two (or more) JSON (or map-like) objects, see. You can run tests with this directly, but teams can choose the JUnit variant (shown below) that pulls in JUnit 5 and slightly improves the in-IDE experience. Otherwise they would be evaluated as expressions - which does come in useful for some dynamic data-driven situations: Yes, you can even nest chunks of JSON in tables, and things work as you would expect. Learn more. The structure should be a def keyword followed by a variable name and a value. """, """ Keep in mind that you should be able to comment-out a Scenario or skip some via tags without impacting any others. As a convenience, cookies from the previous response are collected and passed as-is as part of the next HTTP request. The JavaScript interpreter will try to convert types across Java and JavaScript as smartly as possible. And similarly - for specifying the HTTP proxy. ] What this means is that you are free to use whatever makes sense for you. before you fire the method. Create JDBC connection in the features Background:. So we use the same Gherkin syntax - but the similarity ends there. 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. // trigger download of latest image with custom file name A good example is when you want to use a CSV file as the request-body for a file-upload. The tests eecutes fine if i use maven command or run from runner file( .java). For example, you can: For an advanced example of how you can build and re-use a common set of JS functions, refer to this answer on Stack Overflow. "b": 2, Take a look at how the configure headers example uses the authToken variable. 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. 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. So when you use the combination of callonce in a Background, you can indeed get the same effect as using a @BeforeClass annotation, and you can find examples in the karate-demo, such as this one: callonce.feature. Karate-config.js, Is it possible to run java method after every karate scenario? So you can do things like right-click and run a *.feature file (or scenario) without needing to use a JUnit runner. response is a built-in variable in karate that stores HTTP API response. _ > 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, """ If you have to set a bunch of deeply nested keys, you can move the parent path to the top, next to the set keyword and save a lot of typing ! 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 /. The configure key here is report and it takes a JSON value. Also see type conversion. You can optionally pass in variable values or over-ride config via a HashMap or leave the second-last argument as null. Being able to define and re-use JavaScript functions is a powerful capability of Karate. # using a static method - observe how java interop is truly seamless ! 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. This example uses contains and the #? You dont have to compile code. Another good thing that Karate inherits is the nice IDE support for Cucumber that IntelliJ and Eclipse have. Karate uses LOGBack which looks for a file called logback-test.xml on the classpath. So you get the best of both worlds: the elegance of JSON to express complex nested data - while at the same time being able to dynamically plug values (that could even be other JSON or XML trees) into a template. 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. Keep in mind that the start-up configuration routine could have already initialized some variables before the script even started. First the JavaScript file, basic-auth.js: And heres how it works in a test-script using the header keyword. And you can easily assert that the data is as expected by comparing it with another JSON or XML object. The key should not be within quotes. And it is worth mentioning that the Karate configuration bootstrap routine is itself a JavaScript function. Karate will also run Scenario-s in parallel by default. """, """ _ > 0'. """, # 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, """ For advanced examples, refer to some of the scenarios within this demo: dynamic-params.feature. And a very common need would be to use a file as the request body: The rarely used file: prefix is also supported. Refer to this case study for how dramatic the reduction of lines of code can be. 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. The following parameters are supported: For end-to-end examples in the Karate demos, look at the files in this folder. You can find more JSON examples here: js-arrays.feature. Assuming you use JUnit, there are some good reasons for the recommended (best practice) naming convention and choice of file-placement shown above: For details on what actually goes into a script or *.feature file, refer to the syntax guide. Karate gives us lots of options to work with data. Schedule a free in-home consultation 888-795-3329 or 3dayblinds.com. The keywords def, set, match, request and eval take multi-line input as the last argument. Instead of using call (or callonce) you are always free to call JavaScript functions normally and then you can use more than one argument. However, unlike Cucumber, tests arent written in Java and are fully described in the Gherkin file. for (var n in nums) { will get encoded into %3F. input: API tests are written using Behaviour Driven Development (BDD) Gherkin syntax. You can call send() on the returned object to send a message. to customize rebase filename and/or output), Function to be called when displaying image comparison configuration in Karate HTML reports (e.g. It gets the value of any Java system-property by name. You usually wont need this, but the second-last line above shows how the karate object can be used to evaluate JsonPath if the filter expression depends on a variable. "c": 3 return sdf.parse(s).time; // '.getTime()' would also have worked instead of '.time' Since it is internally implemented as a JavaScript function, you can mix calls to read() freely wherever JavaScript expressions are allowed: Tip: you can even use JS expressions to dynamically choose a file based on some condition: * def someConfig = read('my-config-' + someVariable + '.json'). You can find more details here. By default, the value of karate.env when you access it within karate-config.js - would be null. How do you get out of a corner when plotting yourself into a corner. One of these is the use of a Gherkin file, which describes the tested feature.However, unlike Cucumber, tests aren't written in Java and are fully described in the Gherkin file. Note that the parser is lenient so that you dont have to enclose all keys in double-quotes. 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. One way to appreciate Karates approach is to think over what it takes to add a new environment-dependent variable (e.g. Behaves the same way as the. You can change the com.intuit.karate logger level to INFO to reduce the amount of logging. lastUpdated: { on: "#ignore" }, Karate supports JUnit 5 and the advantage is that you can have multiple methods in a test-class. function(arg) { If a handler function (returning a boolean) is provided - it will be used to complete the listen wait if true is returned. The name of the class doesn't matter, and it will automatically run any *. In such cases, the function can do nothing or return an empty JSON. And there is another example in the karate-demos: schema.feature where you can compare Karates approach with an actual JSON-schema example. You could even have all the steps start with When and Karate wont care. Refer to the section on JsonPath short-cuts for a deeper understanding of named JsonPath expressions in Karate. For a call (or callonce) - payload / data structures (JSON, XML, Map-like or List-like) variables are passed by reference which means that steps within the called feature can update or mutate them, for e.g. 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. height Does ZnSO4 + H2 at high pressure reverses to Zn + H2SO4? Refer to this demo feature for an example: kitten-create.feature. Use this for building multipart named (form) field requests. hero(name: "") { And match (name) contains is how you can do so: Note that match contains will not recurse any nested JSON chunks so use match contains deep instead. Teams typically define complicated JSON (or XML) payloads in a file and then re-use this in multiple scripts. This is perfect for those cases where it really doesnt make sense - for example the Background section or when you use the def or set syntax. Both the official Visual Studio Code and IntelliJ plugins support step-through debugging of Karate tests. Observe how using JSON for parameter-passing makes things super-readable. This section will be run before each script in the feature file. 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. Open the command prompt and change the directory to the project location where pom.xml is present. # and even ignore fields at the same time ! In some rare cases, for e.g. 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. or anything wrapped in parentheses which will be evaluated as JavaScript - e.g. Now, since this Karate Framework is using the Runner file, which also is needed in Cucumber to run the feature files, so most of the writing will follow the Cucumber standards. Open a feature file after you have installed the plug-in. Url encoding is required to differentiate between special characters in your data vs special characters that are reserved to construct the URL. 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. Paste the raw data in textbox. The Maven tradition is to have non-Java source files in a separate src/test/resources folder structure - but we recommend that you keep them side-by-side with your *.java files. This is one reason why you may want to prefer a flat directory structure as explained above. This means that even when you have dynamic server-side generated values such as UUID-s and time-stamps appearing in the response, you can still assert that the full-payload matched in one step. And you can even handle asynchronous flows such as listening to message-queues. If you read from a file, the advantage is that multiple scripts can re-use the same data. to customize configuration output), Array of rectangles that should be ignored during image comparison, Resemble ignore preset. Refer to conditional logic for more ideas. JavaScript Functions are also native. Paste the raw json in it and Save it. and & will be automatically inserted. Note the inline use of the read function as a short-cut above. 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. This will always hold the contents of the response as a byte-array. 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. When the level is DEBUG the entire request and response payloads are logged. In the rare case that you need to mutate a Map or List returned from Java but while still within a JS block, use karate.toJson() to convert. 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. 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. To run a script *.feature file from your Java IDE, you just need the following empty test-class in the same package. Making statements based on opinion; back them up with references or personal experience. The .graphql and .gql extensions are also recognized (for GraphQL) but are handled the same way as .txt and treated as a string. Here I have defined a variable expectedOutput with def keyword. Refer to the documentation for cookie for details and how you can disable this if need be. also explained how to grab the response . So if you take the previous folder structure example, you can do this on the command-line: Here, AnimalsTest is the name of the Java class we designated to run the multiple *.feature files that make up your test-suite. For example, see the sayHelloFactory() method below: And now, to get a reference to that function you can do this: This can be convenient when using shared scope because you can just call sayHello('myname') where needed. Run All Karate Tests.
