The value column can take expressions, even XML chunks. 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. And if you need multiple functions, you can easily organize them into a single Java class with multiple static methods. Wait for the test script to execute. 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. 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. And yes, functions can take arguments. common.feature. Multiple feature files (or paths) can be specified, de-limited by the space character. You can use karate.callSingle() directly in a *.feature file, but it logically fits better in the global "bootstrap". The Gradle setup code would look something like this. Refer to the section on JsonPath short-cuts for a deeper understanding of 'named' JsonPath expressions in Karate. Karate is the only open-source tool to combine API test-automation, mocks, performance-testing and even UI automation into a single, unified framework. Take a look at how the configure headers example uses the authToken variable. 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 Cucumber's support for expressing data-tables. One nice thing about the design of the Gherkin syntax is that script-steps are treated the same no matter whether they start with the keyword Given, And, When or Then. Now it should be clear how Karate makes it easy to express JSON or XML. So the above could be re-written as follows: It is worth repeating that the above can be condensed into 2 lines. This can be convenient if a particular call results in a huge response payload. Step 1 : Open maven preferences in eclipse. To ensure that they don't get run by CI by mistake - just don't use the *Test.java naming convention. Cucumber has a concept of Scenario Outlines where you can re-use a set of data-driven steps and assertions, and the data can be declared in a very user-friendly fashion. The built-in karate object is explained in detail later, but for now, note that this is also injected into print (and even assert) statements, and it has a helpful pretty method, that takes a JSON argument and a prettyXml method that deals with XML. Refer to this video for getting started with the free IntelliJ Community Edition. The Hello World is a great example of 'REST-ful' use of the url when the test focuses on a single REST 'resource'. Note that you can even include calls to a database from Karate using Java interop. Go to TestRunner.java file and Right-click on the file as shown in the below image. path to file containing public and private keys for your client certificate. In such cases, you have to use string quotes: { 'Content-Type': 'application/json' }. In the 'called' feature, the argument can also be accessed using the built-in variable: 'called' Karate scripts don't need to use any special keywords to 'return' data and can behave like 'normal' Karate tests in 'stand-alone' mode if needed, the data 'return' mechanism is 'safe', there is no danger of the 'called' script over-writing any variables in the 'calling' (or parent) script (unless you use, the need to explicitly 'unpack' variables by name from the returned 'envelope' keeps things readable and maintainable in the 'caller' script, call re-usable functions that take complex data as an argument and return complex data that can be stored in a variable, JavaScript / JSON-style mutation of existing, You can disable the "auto variables" behavior by setting the. You can always use a JavaScript function or call Java for more complex logic. Just for illustrative purposes, you could 'hard-code' the karate.env for a specific JUnit 4 test like this. A few more useful "transforms" are to select a sub-set of key-value pairs using karate.filterKeys(), merging 2 or more JSON-s using karate.merge() and combining 2 or more arrays (or objects) into a single array using karate.append(). Once you get used to this, you may even start wondering why projects need a src/test/resources folder at all ! Refer to this example for more details: graphql.feature. You can find more details here. Note that all the short-cut forms on the right-side of the table resolve to 'equality' (==) matches, which enables them to be 'in-lined' into a full (single-step) payload match, using embedded expressions. For example: And similarly for XML and XPath, '/' represents the response. 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. The responseCookies variable is set upon any HTTP response and is a map-like (or JSON-like) object. Empty cells or expressions that evaluate to null will result in the key being omitted from the JSON. 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. 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 is useful when you ship a JAR file containing re-usable features and JavaScript / Java code and want to 'default' a few variables that teams can 'inherit' from. See the section on reading files - and also this example dynamic-csv.feature, which shows off the convenience of dynamic Scenario Outline-s. If needed, this can be changed by using configure - any time during a test, or set globally via karate-config.js. Set up Java ; Set up Eclipse; Set … Refer to conditional logic for more ideas. 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. 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: For suppressing sensitive information such as secrets and passwords from the log, see Log Masking. But you can prefix the name with classpath: in which case the 'root' folder would be src/test/java (assuming you are using the recommended folder structure). The approach in this section is more suited for troubleshooting in dev-mode, using your IDE. Observe the usage of Scenario Outline: instead of Scenario:, and the new Examples: section. This is great for testing boundary conditions against a single end-point, with the added bonus that your test becomes even more readable. Now you will be able to relate to what exactly is written in the above file. What this means is that you are free to use whatever makes sense for you. 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. Also see first.feature and second.feature in the demos. You can adjust configuration settings for the HTTP client used by Karate using this keyword. Else the Runner.path() "builder" API is the same, refer the description above for JUnit 4. The icons change depending on the state of your test: marks new tests; marks successful tests; icon marks failed tests.
