multipart file uploads can be tricky, and hard to get right. For manipulating or updating JSON (or XML) using path expressions, refer to the set keyword. Note that this example only does a string equals check on parts of the JSON, but with Karate you are always encouraged to match the entire payload in one step. { "roomInformation": [{ "roomPrice": 679.79}], "totalPrice": 679.79 } Karate gives us lots of options to work with data. See also match header which is what you would normally need. 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. #string please replace RELEASE with the exact version of Karate you intend to use if applicable. Also make sure that you complete the set up of things like url, param, header, configure etc. You may face issues if you attempt to mix in JS functions or Java code. Bloating your configuration can lead to loss of performance, and maintainability may suffer. Keep in mind that these are tests (not production code) and this config is going to be maintained more by the dev or QE team instead of the ops or operations team. What are the most important features of karate? } The above example actually makes two HTTP requests - the first is a standard sign-in POST and then (for illustrative purposes) another HTTP call (a GET) is made for retrieving a list of projects for the signed-in user, and the first one is selected and added to the returned auth token JSON object. Since match and set go well together, they are both introduced in the examples in the section below. or anything wrapped in parentheses which will be evaluated as JavaScript - e.g. 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. The key should not be within quotes. Set the read timeout (milliseconds). } For example look at how creator has been defined in the Background in this example, and used later in a call statement. var SimpleDateFormat = Java.type('java.text.SimpleDateFormat'); // 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. This is best explained in this example: copy.feature. For completeness, the built-in tags are the following: There are two special tags that allow you to select or un-select a Scenario depending on the value of karate.env. But there are cases where you need to take custom actions like saving a response to a file, file reading or writing, etc. If you want to use JUnit 4, use the karate-junit4 Maven dependency instead of karate-junit5. 2 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 match operation is smart because white-space does not matter, and the order of keys (or data elements) does not matter. It gets the value of any Java system-property by name. Cucumber has a limitation where Background steps are re-run for every Scenario. Add the plugin to the / section of your pom.xml if not already present: If you want to use JUnit 4, use the karate-junit4 Maven dependency instead of karate-junit5. If you find yourself struggling to write dynamic JsonPath filters, look at karate.filter() as an alternative, described just below. 8 How to test the Karate API cheat sheet? Multi-values are supported the way you would expect (e.g. Refer to the cats-java.feature demo for an example. They should be at the end of the karate.options. To run the application in multiple environments choose one of the environment-specific commands from the following: 1] npm run start:development 2] npm run build:staging 3] npm run build:qa 4] npm run build:production Access the variables in-app For accessing the variables in the .env file you should use the process. Keep in mind that you should be able to comment-out a Scenario or skip some via tags without impacting any others. Instead I get this error. 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). In real-life tests, these are very useful when the order of items in arrays returned from the server are not guaranteed. A callonce is ideally used for only pure JSON. 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. You may have to rely on unit-testing frameworks or integrate additional dependencies. You can select a single Scenario (or Scenario-s or Scenario Outline-s or even specific Examples rows) by appending a tag selector at the end of the feature-file you are calling. The match keyword will work as you expect. Sending a file as the entire binary request body is easy (note that multipart is different): The HTTP verb - get, post, put, delete, patch, options, head, connect, trace. For convenience, non-existent keys (or array elements) will be created automatically. But since you can express a list of data-elements as a JSON array - even these XPath expressions can be used in match statements. Although it is just a few lines of code, take time to study the above example carefully. Shinwa-Kai Karate Club (Singapore) is founded in 1997 by Shihan Richard Ng, 7th Dan Black-Belt, NROC Master Coach & National Coach of Singapore. The recipe for doing this when running Maven from the command line is: You can refer to the documentation of the Maven Surefire Plugin for alternate ways of achieving this, but the argLine approach is the simplest and should be more than sufficient for your Continuous Integration or test-automation needs. You could get by by renaming the file-extension to say *.txt but an alternative is to use the karate.readAsString() API. #10, #15: There must be a structure expected as a response of the API. 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(). """, # use dynamic path expressions to mutate json, * def filename = zone == 'zone1' ? Normally an undefined variable results in nasty JavaScript errors. Karate can run tests in parallel, and dramatically cut down execution time. One workaround is to temporarily disable or rename your Maven settings.xml file, and try again. And you can even handle asynchronous flows such as listening to message-queues. id: 1, 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) some.feature:42 so it will invoke only the Scenario or outline Example on line 42 - this is designed only for IDE-s and developer mode, use a . # and even ignore fields at the same time ! Instead, Karate gives you all you need as part of the syntax. Learn more. Normally we recommend that you keep your re-usable features lightweight - by limiting them to just one Scenario. Enable HTTPS calls without needing to configure a trusted certificate or key-store. This turns out to be very useful in practice, and this particular match jsonArray contains '#(^partialObject)' form has no in-line equivalent (see the third-from-last row above). We will use karate.properties [user.dir] which will automatically pick users working directory and then append it to the path of our project files. Refer to your IDE documentation for how to run a JUnit class. Load testing. 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. Also see type conversion. This is one reason why you may want to prefer a flat directory structure as explained above. We can execute the scenarios in the feature file using maven (which is useful to run the tests in a CI environment) import com. Here is an example: You can see the structure of the data here: kittens.json. Since XML is represented internally as a JSON-like or map-like object, if you perform string concatenation when printing, you will not see XML - which can be confusing at first. And such re-use makes it easier to re-factor tests when needed, which is great for maintainability. Open the command prompt and change the directory to the project location where pom.xml is present. When asserting for expected values in JSON or XML, always prefer using match instead of assert. You can easily select (double-click), copy and paste this file: URL into your browser address bar. The default is 30000 (30 seconds). Step 3: Add steps to run a sample GET API request. There should always be karate-config.js in the root folder, even if you dont have any common config. The examples above are simple, but a variety of expression shapes are supported on the right hand side of the = symbol. For example: While the tag does not need to be in the @key=value form, it is recommended for readability when you start getting into the business of giving meaningful names to your Scenario-s. Why is there a voltage on my HDMI and coaxial cables? some.feature:42 so it will invoke only the Scenario or outline Example on line 42 - this is designed only for IDE-s and developer mode, use a tag for maintainability. Karate tool provides you with the step definitions. The name of the SOAP action specified is used as the SOAPAction header. In rare cases, e.g. 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. Note that Karate works fine on OpenJDK. karate.appendTo(vals, y); Karate IDE. And steps that follow should logically be in the Then form. This is a normal JUnit 4 test class ! That said, if you want to stick to JavaScript, but find yourself accumulating a lot of helper functions that you need to use in multiple feature files, the following pattern is recommended. They are param, header, cookie, form field and multipart field. When you use a JUnit runner - after the execution of each feature, an HTML report is output to the target/karate-reports folder and the full path will be printed to the console (see video). 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. 5 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. Refer to the section on XPath Functions for examples of advanced XPath usage. for (var n in nums) { The feature is invoked for each item in the array. It consists of the diamond-shaped Singapore Island and some 60 small islets; the main island occupies all but about 18 square miles of this combined area. Create the Step Definition class or Glue Code for the Test Scenario. If you don't want to run Gatling tests as part of the normal Maven test lifecycle, you can avoid the <executions> section as described previously.. Gradle . This approach can certainly enable product-owners or domain-experts who are not programmer-folk, to review, and even collaborate on test-scenarios and scripts. 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. The above example does not use shared scope, which means that the variables in the calling (parent) feature are not shared by the called my-signin.feature. If you read from a file, the advantage is that multiple scripts can re-use the same data. JavaScript functions have some limitations when combined with multi-threaded Java code. All the fuzzy matching markers will work in XML as well.
