"arr": [ 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. When JavaScript executes in Karate, the built-in karate object provides some commonly used utility functions. Multi-values are supported the way you would expect (e.g. For JSON, you can also use the JS delete operator via eval, useful when the path you are trying to mutate is dynamic. Refer to this for the complete example: schema-like.feature. But this time, the return value from the call step will be a JSON array of the same size as the input array. *.js, *.json, *.txt) as well and it is much more convenient to see the *.java and *.feature files and all related artifacts in the same place. leagueName: '##string', The static method com.intuit.karate.Runner.runFeature() is best explained in this demo unit-test: JavaApiTest.java. _ >= 0', { "roomInformation": [{ "roomPrice": 679.79}], "totalPrice": 679.79 } The match keyword will work as you expect. Refer to the section on JsonPath short-cuts for a deeper understanding of named JsonPath expressions in Karate. It returns the Element representation of whichever element was found first, so that you can perform conditional logic to handle accordingly. # this can be a global re-usable function ! In such cases, you have to use string quotes: { 'Content-Type': 'application/json' }. Given url https://www.kloia.com/ If you want to use JUnit 4, use karate-junit4 instead of karate-junit5. Note that the set (multiple) keyword can build complex, nested JSON (or XML) from scratch in a data-driven manner, and you may not even need to read from files for many situations. Step 1: Create a feature file under src/test/java folder. And yes, variables can come from global config. JavaScript Functions are also native. There are multiple Karate API testing examples we are going to show you in this series. So it is recommended that you directly use a Java Function when possible instead of using the karate.toJava() wrapper as shown above. Since Karate uses Gherkin, you can also employ data-driven techniques such as expressing data-tables in test scripts. You can skip this section and jump straight to the Syntax Guide if you are in a hurry to get started with Karate. You can easily assert that all expected elements are present, even in nested parts of your JSON - while doing a match on the full payload. Here is an example which also demonstrates how you could assert for expected values in the response XML. A very useful capability is to be able to check that an array contains an object that contains the provided sub-set of keys instead of having to specify the complete JSON - which can get really cumbersome for large objects. before you fire the method. See this other example for more ideas: dsl.feature. Internally, Karate will auto-convert JSON (and even XML) to Java Map objects. This is really convenient in dev-local mode. The short cut $variableName form is also supported. Keep in mind that the start-up configuration routine could have already initialized some variables before the script even started. Examples of defining and using JavaScript functions appear in earlier sections of this document. You can read more about the Given-When-Then convention at the Cucumber reference documentation. Keep in mind that the reason this exists is to cache data, and not behavior. A set of real-life examples can be found here: Karate Demos. Also refer to the eval keyword for a simpler way to execute arbitrary JavaScript that can be useful in some situations. Here are the rules Karate uses on bootstrap (before every Scenario or Examples row in a Scenario Outline): Advanced users who build frameworks on top of Karate have the option to supply a karate-base.js file that Karate will look for on the classpath:. Karate Labs is an industry leading open-source test automation solution unifying API & UI test automation. Karate, created by Intuit a few years ago, has matured into a stable tool with unique functionality. - Mix API and UI test-automation. What started as a powerful, scriptable framework combining API and UI test automation, is adopted as a best-practice today - in teams around the world. Typical symptoms are your tests working fine via the IDE but not when running via Maven or Gradle. Instead, Karate gives you all you need as part of the syntax. And each element of the returned array will be the envelope of variables that resulted from each iteration where the *.feature got invoked. This will return all elements that match the locator as a list of Element instances. _ == _$.roomInformation[0].roomPrice' }, """ First, you can maintain a JSON map of your application locators. Karate does not attempt to have tests be in natural language like how Cucumber tests are traditionally expected to be. when a string coming from an external process is dynamic - and whether it is JSON or XML is not known in advance, see, get the value of a variable by name (or JsonPath expression), if not found - this returns, returns only the keys of a map-like object, log to the same logger (and log file) being used by the parent process, logging can be suppressed with, access to the Karate logger directly and log in debug. 1. If you are looking for Cucumber hooks Karate does not support them, mainly because they depend on Java code, which goes against the Karate Way. { Note: desiredCapabilities has been deprecated and not recommended for use. Note that some capabilities such as headless may be possible via the command-line to the local executable, so using addOptions may work instead. The rest can also be used even in primitive data matches like so: If two cross-hatch # symbols are used as the prefix (for example: ##number), it means that the key is optional or that the value can be null. For an example of how JavaScript looks like on the Karate side see Function Composition. If you find yourself needing a complex helper or utility function, we strongly recommend that you use Java because it is much easier to maintain and even debug if needed. Bloating your configuration can lead to loss of performance, and maintainability may suffer. In some cases, for large payloads and especially when the default system encoding is not UTF-8 (Windows or non-US locales), you may run into issues where a java.io.ByteArrayInputStream is encountered instead of a string. The steps which are defined under background will run before each and every scenario for a feature file. = . You can use this to assert that it was returned within the expected time like so: Karate will attempt to parse the raw HTTP response body as JSON or XML and make it available as the response value. If you get stuck trying to align the search path, especially if the origin is a small chunk of text that is aligned right or left - try near(). A karate-timeline.html file will also be saved to the report output directory mentioned above (target/karate-reports by default) - which is useful for visually verifying or troubleshooting the effectiveness of the test-run (see video). The primary classes are described below. Here is an example, where the same websocket connection is used to send as well as receive a message. And as a convenience, whatever object is returned, can be re-used in future steps. It is worth taking a few minutes to go through the documentation and examples here: JsonPath Examples. Theres also a cross-platform stand-alone executable for teams not comfortable with Java. The advantage of this approach is that it works with any of the actions. Use this for multipart content items that dont have field-names. What this means is that it can be chained as you expect. Simple, clean syntax that is well suited for people new to programming or test-automation. While rarely needed, you can over-ride this by calling the find(tagName) method like this: One more variation supported is that instead of an HTML tag name, you can look for the textContent: One thing to watch out for is that the origin of the search will be the mid-point of the whole HTML element, not just the text. If you use commas (instead of concatenating strings using +), Karate will pretty-print variables, which is what you typically want when dealing with JSON or XML. You can change the com.intuit.karate logger level to INFO to reduce the amount of logging. Refer to this case study for how dramatic the reduction of lines of code can be. stop(): Karate will call this method at the end of every top-level Scenario (that has not been call-ed by another Scenario). function(arg) { So you could have also done something like: Also refer to the configure keyword on how to switch on pretty-printing of all HTTP requests and responses. """, "function(e){ return getComputedStyle(e)['font-size'] }", # this shorter version is equivalent to the above, # get text for all elements that match css selector, # now you can have multiple steps refer to "e", # find all elements with the text-content "Click Me", # perform some API calls and initialize the value of "token". Step 4: Run this feature file and get the report in target > karate-reports > karate-summary.html. Since match and set go well together, they are both introduced in the examples in the section below. """, //DEPS com.intuit.karate:karate-core:RELEASE:all, "https://jsonplaceholder.typicode.com/users", * def expected = __num == 0 ? Note that jbang itself is super-easy to install and there is even a Zero Install option. As a rule of thumb, prefer match over assert, because match failure messages are more detailed and descriptive. Best-practice would be to implement Hybrid Tests where the values for the auth-cookies are set only once for the whole test-suite using karate.callSingle(). But if you need to use values in the response headers - they will be in a variable named responseHeaders. Here is an interesting example where a JavaScript event can be triggered on a given HTML element: When starting with _, the ES6 arrow function syntax 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. """, # very useful for validating a response against a schema "super-set", * match karate.filterKeys(response, 'b', 'c') == { c, * match karate.filterKeys(response, ['a', 'b']) == { a, # generate a range of numbers as a json array, """ Path parameter: After defined the URL we need to mention the path to send the request. var date = new java.util.Date(); You can even chain a submit() to wait for a page load if needed: Since moving the mouse is a common task, these short-cuts can be used: These are useful in situations where the normal click() does not work - especially when the element you are clicking is not a normal hyperlink () or . For more details check this link- Embedded Expression. And also note that instead of using the match keyword, you can use karate.match() for very advanced conditional checks. You could even have all the steps start with When and Karate wont care. So the only way to call this Scenario is by using the karate.setup() JS API. count: '#number', You can even initialize the JSON in a separate step and pass it by name, especially if it is complex. In some rare cases, for e.g. 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). A header row is always expected.

Get all my courses for USD 5.99/Month - https://bit.ly/all-courses-subscriptionIn this Karate Tutorial, we will learn about webelement functions in Karate, l. Note that the Java class does not need to be public and even the test methods do not need to be public - so tests end up being very concise. When you use Karate, all your data assertions can be done in pure JSON and without needing a thick forest of companion Java objects. Multiple fields can be set in one step using multipart fields. There are examples of calling JVM classes in the section on Java Interop and in the file-upload demo. """, # karate's unified data handling means that even 'match' works, # which means that checking if a cookie does NOT exist is a piece of cake, # check if the response status is either of two values, # this may be sufficient to check a range of values. Karates callonce keyword behaves exactly like call but is guaranteed to execute only once. Any valid JavaScript expression that evaluates to a Truthy or Falsy value is expected after the #?. When using stand-alone *.js files, you can have a comment before the function keyword, and you can use fn as the function name, so that your IDE does not complain about JavaScript syntax errors, e.g. Karate can split a test-suite across multiple machines or Docker containers for execution and aggregate the results. deleted: false The first will simply return a List of Element instances. 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. playwright) for the start scripts to live. } Note that the JS here has to be a raw string that is simply sent to the browser as-is and evaluated there. The same concept applies to XML and you can build complicated payloads from scratch in just a few, extremely readable lines. # we compose a function using another function (the one above), """ 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. returns the last HTTP response as a JS object that enables advanced use-cases such as getting a header ignoring case: returns the last HTTP request as a JS object that enables advanced use-cases such as getting a header ignoring case: get metadata about the currently executing, sets the value of a variable (immediately), which may be needed in case any other routines (such as the, where the single argument is expected to be a, only needed when you need to conditionally build payload elements, especially XML. The only rule is that on start-up Karate expects a file called karate-config.js to exist on the classpath and contain a JavaScript function. And it is worth mentioning that the Karate configuration bootstrap routine is itself a JavaScript function. How you could assert for expected values in the response headers - they will be the envelope of variables resulted. Callonce keyword behaves exactly like call but is guaranteed to execute only once uses Gherkin, you can karate.match.
