karate run specific feature file

Use either the param keyword, e.g. Windows: Ctrl+R+A. So if you tried to re-use the same feature but with multiple arguments, things will not work as you expect. The examples above are simple, but a variety of expression shapes are supported on the right hand side of the = symbol. You can even perform a conversion from XML to JSON if you want. Name the file as javadsl.java and run using the command: jbang javadsl.java. In the case of the call of a JavaScript function, you can also pass a JSON array or a primitive (string, number, boolean) as the solitary argument, and the function implementation is expected to handle whatever is passed. Add an automation story in BDD syntax. You can find more examples here: xml.feature. There is a neat way to tag your tests and the above example demonstrates how to run all tests except the ones tagged @skipme. Take a look at how the configure headers example uses the authToken variable. 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. 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. This example uses contains and the #? When I switch environments (passing in -Dkarate.env=qual as part of the run command) then baseUrl is set correctly. Note that the ? And you can perform conditional / cross-field validations and even business-logic validations at the same time. sportName: '#string', You can also sort arrays of arbitrary JSON using karate.sort(). The above code reads a template which is in location com/example/templates/idm/idm-create-user-template.json and stores it as a JSON variable called myReq Then we can send the JSON variable to the other feature file using the call method. so if you are going to pass any special characters as data via URL you need to % encode them to avoid conflicts. Once you get a result, you typically use it to set global variables. You simply do something like this: A common need is to send the same header(s) for every request, and configure headers (with JSON) is how you can set this up once for all subsequent requests. Note that if you did not need to inject Examples: into placeholders enclosed within < and >, reading from a file with the extension *.txt may have been sufficient. Multiple feature files (or paths) can be specified, de-limited by the space character. 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:. Only 1 import is needed, and instead of a class-level annotation, you use a nice DRY and fluent-api to express which tests and tags you want to use. Note that even the scenario name can accept placeholders - which is very useful in reports. 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. """, """ to customize configuration output), Array of rectangles that should be ignored during image comparison, Resemble ignore preset. Syntax highlighting should work right away and if you don't see something similar like in the following screenshot, make sure you have selected karate as . The most common use-case would be to partition your tests into smoke, regression and the like - which enables being able to selectively execute a sub-set of tests. ] See also match header which is what you would normally need. For a call (or callonce) - payload / data structures (JSON, XML, Map-like or List-like) variables are passed by reference which means that steps within the called feature can update or mutate them, for e.g. This is useful for testing payloads with JSON arrays whose members have a few essential keys that you wish to validate. Install Karate VS Code Plugin. To make dynamic data-driven testing easier, the following keywords also exist: params, headers, cookies and form fields. var SimpleDateFormat = Java.type('java.text.SimpleDateFormat'); The default is 30000 (30 seconds). This enables more concise tests, and the file can be re-usable in multiple, data-driven tests. This is technically not in the key-value form: multipart field name = 'foo', but logically belongs here in the documentation. Create JDBC connection in the features Background:. Use this for multipart content items that dont have field-names. "c": 3 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. You can use karate.abort() like so: Using karate.abort() will not fail the test. 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). To learn more, see our tips on writing great answers. Linux: Ctrl+Shift+R+1. Since the karate object is injected within karate-config.js on start-up, it is a simple and effective way for other processes within the same JVM to pass configuration values to Karate at run-time. input: or $[. Karate is an open-source general-purpose test-automation framework that can script calls to HTTP end-points and assert that the JSON or XML responses are as expected. With this, we will execute our test cases in parallel format. When using call (or callonce), only one argument is allowed. The JS API has a karate.signal(result) method that is useful for involving asynchronous flows into a test. What are the features of a Karate test script? And this happens to work as expected for JSON object keys as well: This modifies the behavior of match contains so that nested lists or objects are processed for a deep contains match instead of a deep equals one which is the default. Provides supports for the Data Driver Testing that is built in-house, hence no need to depend on external frameworks. Note that more builder methods are available from the Runner.Builder class such as reportDir() etc. This is very useful to boil-down those common steps that you may have to perform at the start of multiple test-scripts - into one-liners. Although it is just a few lines of code, take time to study the above example carefully. See karate.callSingle(). response is a built-in variable in karate that stores HTTP API response. before you fire the method. # using a static method - observe how java interop is truly seamless ! Assuming you use JUnit, there are some good reasons for the recommended (best practice) naming convention and choice of file-placement shown above: For details on what actually goes into a script or *.feature file, refer to the syntax guide. Here is an example of how to get the current date, and formatted the way you want: And the above will result in something like this being logged: [print] 2017/10/16. For example look at how creator has been defined in the Background in this example, and used later in a call statement. 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). The syntax is similar to def but instead of a named variable, you update configuration. Another good thing that Karate inherits is the nice IDE support for Cucumber that IntelliJ and Eclipse have. Try this especially if you dont have much experience with programming or test-automation. Multi-values are supported the way you would expect (e.g. The match syntax involves a double-equals sign == to represent a comparison (and not an assignment =). This is a sample Spring Boot web-application that exposes some functionality as web-service end-points. Note how we read as a string, but cast to JSON: If you want to use the triple-quote / multi-line way of defining JSON or if you have to use XML - you can use text and cast to JSON or XML as a second step - before using in a match: Karates match is strict, and the case where a JSON key exists but has a null value (#null) is considered different from the case where the key is not present at all (#notpresent) in the payload. isValidTime(_)' If a handler function (returning a boolean) is provided - it will be used to complete the listen wait if true is returned. This is especially useful when you want to maintain passwords, secrets or even URL-s specific for your local dev environment. 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. Then we can run the mem_report helper function to check the used/available GPU statistics. Also see the option below, where you can data-drive an Examples: table using JSON. And includes a set of Karate examples that test these services as well as demonstrate various Karate features and best-practices. 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. Embedded expressions also make more sense in validation and schema-like short-cut situations. A good example is when you want to use a CSV file as the request-body for a file-upload. If you are trying to build dynamic URLs including query-string parameters in the form: http://myhost/some/path?foo=bar&search=true - please refer to the param keyword. And such re-use makes it easier to re-factor tests when needed, which is great for maintainability. convenient way to execute an OS specific command and return the console output e.g. The first four below are best explained in this example file: type-conv.feature. 1. For JSON and XML files, Karate will evaluate any embedded expressions on load. """, # 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. You can add (or over-ride) variables by passing a call argument as shown above. For example: And if you need to suppress placeholder substitution for read(), but still need a JSON snippet, you can do this. Karate has an elegant way to set multiple keys (via path expressions) in one step. Notice how once the authToken variable is initialized, it is used by the above function to generate headers for every HTTP call made as part of the test flow. # and yes, you can assert against nested objects within JSON arrays ! The placeholder format defaults to angle-brackets, for example: . Step 4: Run this feature file and get the report in target > karate-reports > karate-summary.html. As mentioned above, most CI tools would be able to process the JUnit XML output of the parallel runner and determine the status of the build as well as generate reports. Copyright 2022 it-qa.com | All rights reserved. You can re-use the function you create across your whole project. When you have a sequence of HTTP calls that need to be repeated for multiple test scripts, Karate allows you to treat a *.feature file as a re-usable unit. You can perform database validations with karate by following the below steps. } How can karate read data from external files? Shinwa-Kai Karate Club (Singapore) is founded in 1997 by Shihan Richard Ng, 7th Dan Black-Belt, NROC Master Coach & National Coach of Singapore. 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. The listenResult magic variable will hold the value passed to the call to karate.signal(). A Java API also exists for those who prefer to programmatically integrate Karates rich automation and data-assertion capabilities. There is no need to escape characters like you would have had to in Java or other programming languages. Expressions are evaluated using the embedded JavaScript engine. 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. Karate is built on top of Cucumber, another BDD testing framework, and shares some of the same concepts. The value column can take expressions, even XML chunks. Behavior Driven Development (BDD) is an approach to development and testing, when special attention is paid to product behavior in business terms. in just one extra line you can save the value of karate.prevRequest and pass it around. A URL remains constant until you use the url keyword again, so this is a good place to set-up the non-changing parts of your REST URL-s. A URL can take expressions, so the approach below is legal. Karate is an open-source API test automation tool. It typically ends up being a one-liner that appears in the Background section at the start of your test-scripts. You can even retrieve operating-system environment variables via Java interop as follows: var systemPath = java.lang.System.getenv('PATH'); This decision to use JavaScript for config is influenced by years of experience with the set-up of complicated test-suites and fighting with Maven profiles, Maven resource-filtering and the XML-soup that somehow gets summoned by the Maven AntRun plugin. If a file does not end in .json, .xml, .yaml, .js, .csv or .txt, it is treated as a stream - which is typically what you would need for multipart file uploads. How to check service status in karate DSL? How to call custom Java code in karate API tests? 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). 8 How to test the Karate API cheat sheet? Just write tests in a simple, readable syntax - carefully designed for HTTP, JSON, GraphQL and XML. If you want to dynamically and programmatically determine the tags and features to be included - the API also accepts. function(x, y, i) { Here are the configuration keys supported: If you need to set any of these globally you can easily do so using the karate object in karate-config.js - for e.g: In rare cases where you need to add nested non-JSON data to the configure value, you have to play by the rules that apply within karate-config.js. input: { And if you need multiple functions, you can easily organize them into a single Java class with multiple static methods. If you are new to programming or test-automation, refer to the options for IDE support and the official IntelliJ plugin is recommended. The most important feature of Karate isno coding. There is also a karate.mapWithKey() for a common need - which is to convert an array of primitives into an array of objects, which is the form that data driven features expect. } mass The default is 30000 (30 seconds). """, # 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. The answer is no. To run a script *.feature file from your Java IDE, you just need the following empty test-class in the same package. mvn clean test-compile gatling:test -Dgatling.simulationClass=Performance.GatlingTest Gatling script with Karate feature file. 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. Karate API Test Script. foo: 'hello', Something worth mentioning here is that you would hardly need to use assert in your test scripts. For a proxy that requires authentication, set the, The charset that will be sent in the request, HTTP requests and responses (including headers) will appear in the HTML report, default. HTML form fields would be URL-encoded when the HTTP request is submitted (by the method step). Refer to the documentation for cookie for details and how you can disable this if need be. c We suggest that you have a folder hierarchy only one or two levels deep - where the folder names clearly identify which resource, entity or API is the web-service under test. params, headers, cookies, form fields, multipart fields and multipart files take a single JSON argument (which can be in-line or a variable reference), and this enables certain types of dynamic data-driven testing, especially because any JSON key with a null value will be ignored. return a pretty-printed, nicely indented string representation of the JSON value, also see: return a pretty-printed, nicely indented string representation of the XML value, also see: get the value of any Java system-property by name, useful for, returns a JSON array of integers (inclusive), the optional third argument must be a positive integer and defaults to 1, and if start < end the order of values is reversed, very rarely used - when needing to perform conditional removal of JSON keys or XML nodes. Here is an example: testCompile 'com.intuit.karate:karate-junit5:1.3.1', systemProperty "karate.options", System.properties.getProperty("karate.options"), systemProperty "karate.env", System.properties.getProperty("karate.env"), "ch.qos.logback.classic.filter.ThresholdFilter", // don't waste time waiting for a connection or if servers don't respond within 5 seconds, # steps here are executed before each Scenario in this file, # variables defined here will be 'global' to all scenarios, # and will be re-initialized before every scenario, # assigning a number (you can use '*' instead of Given / When / Then). When you have a large and complex project, you will end up with a few data files (e.g. There can be multiple Scenario-s in a *.feature file, and at least one should be present. See also responseStatus if you want to do some complex assertions against the HTTP status code. Type the following commands: mvn spring-boot:run & mvn test -Dtest=KarateTests. You can easily get the value of the current environment or profile, and then set up global variables using some simple JavaScript. IMPORTANT: There are some restrictions when using callonce or karate.callSingle() especially within karate-config.js. Let's have a look over the a very simple and plane gatling script which uses Karate . if an API needs to be called to get a JSON array, you can call a separate Scenario to set up this data. In rare cases you may want to use a csv-file as-is and not auto-convert it to JSON. We just need to follow the Karate DSL syntax. Difference between "select-editor" and "update-alternatives --config editor". Run Karate Test. You also have the option of setting multiple cookies in one-step using the cookies keyword. myInt + ''), in some rare cases, you may need to convert a string to a number. When JavaScript executes in Karate, the built-in karate object provides some commonly used utility functions. Billie This should make it clear why Karate does not provide out of the box support for any particular HTTP authentication scheme. Karate can run tests in parallel, and dramatically cut down execution time. this is what most teams do. Of course it is an option to have Karate tests in a separate stand-alone maven project and folder, while still being in the same Git repository. Requirement: Open a feature file in VSCode Editor and ensure editor has focus. _ > 0' }, # when validation logic is an 'equality' check, an embedded expression works better, Then match temperature contains { fahrenheit, # when the response is binary (byte-array), # incidentally, match and assert behave exactly the same way for strings, # if b can be present (optional) but should always be null, """ Now, lets continue with the variables in Karate. You may have to rely on unit-testing frameworks or integrate additional dependencies. 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. When your project gets complex, you can have separate karate-config-.js files that will be processed for that specific value of karate.env. 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). 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. But there is an elegant way you can specify a default value using the karate.get() API: A word of caution: we recommend that you should not over-use Karates capability of being able to re-use features. Contrary to the docs, Karate does limit us regarding values we pass between feature files. Karates capabilities include being able to run tests in parallel, HTML reports and compatibility with Continuous Integration tools. And karate.appendTo() is for updating an existing variable (the equivalent of array.push() in JavaScript), which is especially useful in the body of a karate.forEach(). For example a lot of Java projects directly (or indirectly) depend on Netty or Thymeleaf or ANTLR, etc. Definition. VNC server exposed on port 5900 so that you can watch the browser in real-time. It is worth taking a few minutes to go through the documentation and examples here: JsonPath Examples.
