karate run specific feature file
You should see the Karate: Run | Karate: Debug code lense on top of the feature and every scenario. Note that embedded expressions will be evaluated even when you read() from a JSON or XML file. Also look at the section on commonly needed utilities for more ideas. But you can suffix a ?name to the feature to de-dupe it, like so: Now adminResponse and userResponse will be different, even though the same feature file is being used for a callSingle(). So we use the same Gherkin syntax - but the similarity ends there. For this, Cucumber has already provided a way to organize your scenario execution by using tags in feature file. 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. Type the following commands: mvn spring-boot:run & mvn test -Dtest=KarateTests. Here is an example of using a CSV file as the request-body: Karate provides a flexible way to compare two images to determine if they are the same or similar. Any Karate expression can be used in the cell expression, and you can even use Java-interop to use external data-sources such as a database. Karate is even able to ignore fields you choose - which is very useful when you want to handle server-side dynamically generated fields such as UUID-s, time-stamps, security-tokens and the like. It validates the entire payload in one step and checks if the kittens array contains all the expected items but in any order. Else the Runner.path() builder API is the same, refer the description above for JUnit 4. The name of the class doesnt matter, and it will automatically run any *. Karate is built on top of Cucumber, another BDD testing framework, and shares some of the same concepts. Here is an example: You can see the structure of the data here: kittens.json. The section on Karate Expressions goes into the details. for advanced users - scripts can introspect the tags that apply to the current scope, refer to this example: for even more advanced users - Karate natively supports tags in a, when you want to get the absolute OS path to the argument which could even have a prefix such as, converts a JSON string or map-like object into a Java object, given the Java class name as the second argument, refer to this, converts a JSON array (of objects) or a list-like object into a CSV string, writing this to a file is your responsibility or you could use, rarely used, when you need to pass a JS function to custom Java code, typically for, for advanced conditional logic when object types are dynamic and not known in advance, see, returns only the values of a map-like object (or itself if a list-like object), will wait until the URL is ready to accept HTTP connections, will wait until the host:port is ready to accept socket connections, the current iteration index (starts from 0) if being called in a loop, will be, Java knowledge is not required and even non-programmers can write tests, Scripts are plain-text, require no compilation step or IDE, and teams can collaborate using Git / standard SCM, Based on the popular Cucumber / Gherkin standard - with, Eliminate the need for Java Beans or helper code to represent payloads and HTTP end-points, and, Ideal for testing the highly dynamic responses from, Tests are super-readable - as scenario data can be expressed in-line, in human-friendly, Express expected results as readable, well-formed JSON or XML, and, Embedded JavaScript engine that allows you to build a library of, Re-use of payload-data and user-defined functions across tests is, Standard Java / Maven project structure, and, Reports include HTTP request and response, Easily invoke JDK classes, Java libraries, or re-use custom Java code if needed, for. A set of real-life examples can be found here: Karate Demos. Karate-config.js, Is it possible to run java method after every karate scenario? You can do this by multiplying by 1 or using the built-in JavaScript parseInt() function: As per the JSON spec, all numeric values are treated as doubles, so for integers - it really doesnt matter if there is a decimal point or not. Thanks for contributing an answer to Stack Overflow! For an example, refer: upload-multiple-files.feature. This is very close to how custom keywords work in other frameworks. """, """ The function has to return a JSON object. ] For those who may prefer YAML as a simpler way to represent data, Karate allows you to read YAML content from a file - and it will be auto-converted into JSON. Observe how you can match the result of a JsonPath expression with your expected data. In this file, we will write out the test scenarios that need to be executed for performing the API Testing. 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. As a short-cut, when running JsonPath expressions - $ represents the response. 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. Note the extra convenience where you dont have to enclose the LHS key in quotes. leagueName: '##string', This is useful when you want to express a one-off lengthy snippet of text in-line, without having to split it out into a separate file. 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. Refer to the cats-java.feature demo for an example. But first, a special short-cut for array validation needs to be introduced: This in-line short-cut for validating JSON arrays is similar to how match each works. One example of when you may want to convert JSON (or XML) to a string is when you are passing a payload to custom code via Java interop. And the JSON will still be well-formed, and editable in your IDE or text-editor. 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. Parallel testing is the core functionality that is provided by the Karate itself, hence we need not depend on Maven, Gradle, etc. Also take a look at how a special case of embedded-expressions can remove key-value pairs from a JSON (or XML) payload: Remove if Null. This is best explained in this example that involves listening to an ActiveMQ / JMS queue. This is just to reduce confusion for users new to Karate who tend to do * def request = {} and expect the request body or similarly, the url to be set. This can be done via the maven-surefire-plugin configuration. The extension of the feature file is " .feature ". 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. karate.appendTo(idxs, i); In fact Gherkin supports the catch-all symbol * - instead of forcing you to use Given, When or Then. var date = new java.util.Date(); { id: 23, name: 'Bob' }, This is especially useful when you want to maintain passwords, secrets or even URL-s specific for your local dev environment. Wood shutters will run you $200 to $350 per . Here are some example assertions performed while scraping a list of child elements out of the JSON below. There are examples of calling JVM classes in the section on Java Interop and in the file-upload demo. Though not really recommended, you can have multiple Scenario-s within a Feature tagged with @setup. Setting values on JSON documents is simple using the set keyword. This is exactly like match == but the order of arrays does not matter. To force a null value, wrap it in parentheses: An alternate way to create data is using the set multiple syntax. So in dev mode you can easily set this behavior like this. The Background is optional. You can then skip the next few sections, as the pom.xml, recommended directory structure, sample test and JUnit 5 runners - will be created for you. Since templates can be loaded using the classpath: prefix, you can even re-use templates across your projects via Java JAR files. Karate tool provides you with the step definitions. Some users need callable features that are re-usable even when variables have not been defined by the calling feature. Refer to karate.tags and karate.tagValues. And as a testing framework, Karate discourages tests that give different results on every run. Of course the actual time-durations, and logs will be missing, and everything will pass. Look at how the path did not need to be specified for the second HTTP get call since /cats is part of the url. It is worth mentioning that to do the equivalent of the last line in Java, you would typically have to traverse 2 Java Objects, one of which is within a list, and you would have to check for nulls as well. You could get by by renaming the file-extension to say *.txt but an alternative is to use the karate.readAsString() API.
