When asserting for expected values in JSON or XML, always prefer using match instead of assert. for simulating check-boxes and multi-selects): You can also dynamically set multiple fields in one step using the form fields keyword. 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). input: { The approach in this section is more suited for troubleshooting in dev-mode, using your IDE. It is worth repeating that in most cases you wont need to set the Content-Type header as Karate will automatically do the right thing depending on the data-type of the request. Enable HTTPS calls without needing to configure a trusted certificate or key-store. And there is no more worrying about Maven profiles and whether the right *.properties file has been copied to the proper place. if the name is "first": And if you use IntelliJ - you can right click and do the above. To create a feature file, right click on the Project explorer, choose New >> File. height Feature: We use it to identify the feature file and give it a small title or a one line definition. 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. This is especially relevant when manipulating GraphQL queries - because although they look suspiciously like JSON, they are not, and tend to confuse Karates internals. The feature file is an entry point, to write the cucumber tests and used as a live document at the time of testing. Karate Demo. To learn more, see our tips on writing great answers. You can re-use the function you create across your whole project. Karate provides an elegant native-like experience for placeholder substitution within strings or text content. return sdf.format(date); If you want to use JUnit 4, use the karate-junit4 Maven dependency instead of karate-junit5 . Parallel testing is the core functionality that is provided by the Karate itself, hence we need not depend on Maven, Gradle, etc. Note that for very complicated projects you can consider using a Maven profile so that testing-related dependencies dont collide with your development-time dependencies. For example: You can reset default settings by using the following short-cut: Since you can use configure any time within a test, you have control over which requests or steps you want to show / hide. Note that if you tag Examples like this, and if a tag selector is used when running a given Feature - only the Examples that match the tag selector will be executed. !contains deep is not yet supported, please contribute code if you can. The karate-chrome Docker is an image created from scratch, using a Java / Maven image as a base and with the following features: Chrome in "full" mode (non-headless) Chrome DevTools protocol exposed on port 9222. If parsing fails, Karate will log a warning and the value of response will then be a plain string. feature file from your Java IDE, you just need the following empty test-class in the same package. { (with no space in between). If you are new to programming or test-automation, refer to the options for IDE support and the official IntelliJ plugin is recommended. For example: And similarly for XML and XPath, / represents the response. Keep in mind that the reason this exists is to cache data, and not behavior. """, # attempt to detect and ignore antialiasing, # customize color / brightness tolerances, # switch to `original` grayscale SSIM algorithm, # JS math can introduce a decimal point in some cases, # but you can easily coerce to an integer if needed, # or you can do the same on multiple lines if you wish, # set headers or params (if any) BEFORE the method step. 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. For example: For Gradle, you must extend the test task to allow the karate.options to be passed to the runtime (otherwise they get consumed by Gradle itself). Windows: Ctrl+R+A. odds: '#[] oddSchema' Karate can run tests in parallel, and dramatically cut down execution time. 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. The documentation on how to run tests via the command line has an example of how to use tags to decide which tests to not run (or ignore). } {}, """ } 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. """, """ physics Instead, Karate gives you all you need as part of the syntax. JSON objects become Java Map-s, JSON arrays become Java List-s, and Java Bean properties are accessible (and update-able) using dot notation e.g. When you have a runner class in place, it would be possible to run it from the command-line as well. There may be cases where you want to suppress this to make the reports lighter and easier to read. So we use the same Gherkin syntax - but the similarity ends there. { But in that case you should de-dupe them using a name: And since it is common to run a @setup Scenario only once per-feature you can call karate.setupOnce(). ] Refer to the cats-java.feature demo for an example. It is a great example of how to effectively use the unique combination of Cucumber and JsonPath that Karate provides. In other words, when call or callonce is used without a def, the called script not only shares all variables (and configure settings) but can update the shared execution context. Prefer classpath: when a file is expected to be heavily re-used all across your project. In fact Gherkin supports the catch-all symbol * - instead of forcing you to use Given, When or Then. If you want to use JUnit 4, use the karate-junit4 Maven dependency instead of karate-junit5. Do look at the documentation and example for configure headers also as it goes hand-in-hand with call. Since replace auto-converts the result to a string, make sure you perform type conversion back to JSON (or XML) if applicable. JavaScript functions have some limitations when combined with multi-threaded Java code. The special tag @report=false can be used, and it can even be used only for a single Scenario: In cases where you want to mask values which are sensitive from a security point of view from the output files, logs and HTML reports, you can implement the HttpLogModifier and tell Karate to use it via the configure keyword. And for dealing with binary content - see bytes. Refer to JsonPath short-cuts for a detailed explanation. After one year KarateIDE have reached Version 1.0.0.The best user experience for KarateDSL, by far!! } This example actually calls into existing Java code, and being able to do this opens up a whole lot of possibilities. Any valid XPath expression is allowed on the left-hand-side of a match statement. The section on Karate Expressions goes into the details. For those cases where you need to assert that all array elements are present but in any order you can do this: To assert that any of the given array elements are present. before you fire the method. """, """ You can call send() on the returned object to send a message. And yes, variables can come from global config. The syntax will include a = sign between the key and the value. Now we are all set for the Parallel execution with 2. features file. } var sdf = new SimpleDateFormat('yyyy/MM/dd'); A special case of embedded expressions can remove a JSON key (or XML element / attribute) if the expression evaluates to null. Can I tell police to wait and call a lawyer when served with a search warrant? entityState: "ACTIVE" path to file containing public and private keys for your client certificate. Refer to the section on dynamic port numbers for an example. The configure key here is report and it takes a JSON value. {2}', id: '#uuid' }, # convenient (and recommended) way to check for array length, # here we enclose in round-brackets to preserve the optional embedded expression, # so that it can be used later in a "match", """ The demo also features code-coverage using Jacoco, and some tips for even non-Java back-ends. cucumber. """, # normal 'equality' match. Other errors could be a java.net.URISyntaxException and match not working as expected because of special or foreign characters, e.g. Then we can run the mem_report helper function to check the used/available GPU statistics. ] The value column can take expressions, even XML chunks. Refer to the documentation for cookie for details and how you can disable this if need be. Take a look at how the configure headers example uses the authToken variable. Name the file as javadsl.java and run using the command: jbang javadsl.java. Comma delimited values are supported which can be more convenient, and takes care of URL-encoding and appending / between path segments as needed. It can be easily inspected or used in expressions. While this sounds dangerous and should be used with care (and limits readability), the reason this feature exists is to quickly set (or over-write) a bunch of config variables when needed. For JSON and XML files, Karate will evaluate any embedded expressions on load. Use the classpath: prefix to load from the classpath instead. a JSON array). This will give you the usual HTML report showing what features will be run, including all steps shown (including comments) so that it can be reviewed. return sdf.parse(s).time; // '.getTime()' would also have worked instead of '.time' You can add (or over-ride) variables by passing a call argument as shown above. *.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. . 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. You can perform database validations with karate by following the below steps. Calling a feature file from another file. If you continue to use this site we will assume that you are happy with it. If you mix Karate into a Maven or Gradle project with many other dependendies, you may run into problems because of dependency conflicts. name: 'Billie', Because of how easy it is to set HTTP headers, Karate does not provide any special keywords for things like the Accept header. 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). Some third-party report-server solutions integrate with Karate such as ReportPortal.io. 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. So it is recommended that you directly use a Java Function when possible instead of using the karate.toJava() wrapper as shown above. Also look at the section on commonly needed utilities for more ideas. Create JDBC connection in the features Background:. response is a built-in variable in karate that stores HTTP API response. """, # * match cat == { name: '#ignore', type: '#regex . How to specify a single scenario with jar file? Note that Karate has built-in support for CSV files and here is an example: dynamic-csv.feature. a named JsonPath or XPath expression - e.g. This is especially useful when capturing screenshots during tests and comparing against baseline images that are known to be correct. In the above example, the end-result of the call to my-signin.feature resulted in the authToken variable being initialized. Valid options are, Function to be called when displaying image comparison rebase in Karate HTML reports (e.g. The response is automatically available as a JSON, XML or String object depending on what the response contents are. There are two types of code that can be call-ed. Also refer to the wiki for using Karate with Gradle. 5 Karate will traverse sub-directories and look for *.feature files. 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. The JavaScript interpreter will try to convert types across Java and JavaScript as smartly as possible. Karate tool provides you with the step definitions. Staging Ground Beta 1 Recap, and Reviewers needed for Beta 2. You have to repeat the Examples section for each tag. This is typically combined with multipart file as shown below. You can even initialize the JSON in a separate step and pass it by name, especially if it is complex. auth tokens) only once for all of your tests. subType: { name: 'Smith', deleted: false } For advanced examples, refer to some of the scenarios within this demo: dynamic-params.feature. This report is useful for troubleshooting and debugging a test because all requests and responses are shown in-line with the steps, along with error messages and the output of print statements. 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. If you want to use JUnit 4, use karate-junit4 instead of karate-junit5. 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. Note that the special, built-in tag @ignore will always be skipped by default, and you dont need to specify ~@ignore anywhere. IMPORTANT: There are some restrictions when using callonce or karate.callSingle() especially within karate-config.js. Click on Run the Workflow and Start. } For performance reasons, you can implement enableForUri() so that this activates only for some URL patterns. Normally we recommend that you keep your re-usable features lightweight - by limiting them to just one Scenario. For another example, see: examples.feature. } Heres a reminder that running any single JUnit test via Maven can be done by: Where CatsRunner is the JUnit class name (in any package) you wish to run. For example - if a response data element or downloaded file is YAML and you need to use the data in subsequent steps. } To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Here is a recap of symbols that can be used in JSON embedded expressions: There is a shortcut for match each explained in the next section that can be quite useful, especially for in-line schema-like validations. return jd.doWork(arg); It is sometimes useful to be able to check if a key-value-pair does not exist. ] karate.appendTo(keys, x); The Hello World is a great example of REST-ful use of the url when the test focuses on a single REST resource. This can be done via the maven-surefire-plugin configuration. One extra convenience for JSON is that if the variable itself (which was cat in the above example) does not exist, it will be created automatically. Both the official Visual Studio Code and IntelliJ plugins support step-through debugging of Karate tests. String interpolation will support variables in scope and / or the Examples (including functions defined globally, but not functions defined in the background). 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. Insert spring-jdbc and mysql-connector-java to pom.xml. The name of the SOAP action specified is used as the SOAPAction header. var squares = []; All you need is available in the karate-core artifact. Another good thing that Karate inherits is the nice IDE support for Cucumber that IntelliJ and Eclipse have. The example below combines this with the advanced features described above. JSON can be combined with the ability to call other *.feature files to achieve dynamic data-driven testing in Karate. Note that the parallel runner will run Scenario-s in parallel, which means they can run in any order. In such cases, you have to use string quotes: { 'Content-Type': 'application/json' }. Valid options are, Resemble option to ignore a specific color, Resemble option to override preset tolerances for color and brightness, SSIM grayscale algorithm.
