} Only supported for type: 'chrome' - this will wait for a JS promise to resolve and then return the result as a JSON object. Just write tests in a simple, readable syntax - carefully designed for HTTP, JSON, GraphQL and XML. Do note that when passing JSON, the default Map and List representations should suffice for most needs (see example), and using them would avoid un-necessary string-conversion. Name the file as javadsl.java and run using the command: jbang javadsl.java. Once you get a result, you typically use it to set global variables. Also note that multipart file takes a JSON argument so that you can easily set the filename and the contentType (mime-type) in one step. Note that def can be used to assign a feature to a variable. It will create a Karate report under Karate Project > target > Karate report > karate-summary.html, Step 4: Create a TestRunner.java class under src/test/java. # but using karate.range() you can even do this ! Comma delimited values are supported which can be more convenient, and takes care of URL-encoding and appending / between path segments as needed. So even if your next step is the ENTER key, you can do this: Karate will do the best it can to detect a page change and wait for the load to complete before proceeding to any step that follows. Here is the above example re-written to do so: The result of karate.setup() will be a JSON of all the variables created within the Scenario tagged with @setup. Karate supports the following functional-style operations via the JS API - karate.map(), karate.filter() and karate.forEach(). You could get by by renaming the file-extension to say *.txt but an alternative is to use the karate.readAsString() API. a login flow) into a common feature that can be called from multiple test-scripts. This form of waitUntil() is very useful for waiting for some HTML element to stop being disabled. var JavaDemo = Java.type('com.mycompany.JavaDemo'); For details of scope and visibility of variables, see Script Structure. We recommend that you use the Karate extension for Visual Studio Code - and with that, JavaScript, .NET and Python programmers will feel right at home. Defining the request is mandatory if you are using an HTTP method that expects a body such as post. 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. Use the comma-delimited form (see above) or the JS helper (see below). Note that scriptAll() will return an array, as opposed to script(). return sdf.parse(s).time; // '.getTime()' would also have worked instead of '.time' A very powerful variation of waitUntil() takes a full-fledged JavaScript function as the argument. The keywords Given When Then are only for decoration and should not be thought of as similar to an if - then - else statement. } All the methods that return the following Java object types are chain-able. But when you deal with complex, nested JSON (or XML) - it may be easier in some cases to use replace, especially when you want to substitute multiple placeholders with one value, and when you dont need array manipulation. Note: You can use Jsonpathfinder to find the path of json data. Valid options are, The number of bits used to encode each pixel, The maximum size on the smallest dimension before downsampling. { To force a null value, wrap it in parentheses: An alternate way to create data is using the set multiple syntax. Karate is an external domain-specific language based on Gherkin language to create API, Web UI, and Desktop UI tests. You should be able to right-click and run a single method using your IDE - which should be sufficient when you are in development mode. Note that a single JS function is sufficient to transform a given JSON object into a completely new one, and you can use complex conditional logic if needed. Note that you would typically want to use the @ignore tag for such cases. "c": 3 input: { 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. """, * configure imageComparison = { onShowConfig, # don't embed the image comparison UI when the latest image is the same / similar to the baseline (e.g. 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. Also look at the section on commonly needed utilities for more ideas. It also details how a third-party library can be easily used to generate some very nice-looking reports, from the JSON output of the parallel runner. In cases where the data-source needs multiple steps, for e.g. It validates the entire payload in one step and checks if the kittens array contains all the expected items but in any order. 12341234 So now you have testAccounts, leftNav and transactions as variables, and you have a nice name-spacing of locators to refer to - within your different feature files: And this is how you can have all your locators defined in one place and re-used across multiple tests. Job specializations: IT/Tech. But there is a twist ! But if you really need to use the HTTP response code in an expression or save it for later, you can get it as an integer: Note that match can give you some extra readable options: The response time (in milliseconds) for the current response would be available in a variable called responseTime. 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. if you want to conditionally stop a test with a descriptive error message, e.g. But the recommended way is to use the karateEnv(name, value) or systemProperty(name, value) API on the parallel-runner. function() { It is also possible to invoke a feature file via a Java API which can be useful in some test-automation situations. 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. Karate has the following short-cut symbols designed to be mixed into embedded expressions: For completeness, == and != also belong in the above list. You can start a Driver instance programmatically and perform actions and assertions like this: You can find the complete example here. Although rarely needed, variable references or expressions are also supported: This is a shortcut to assert the HTTP response code. And path blog Do note that if you choose the Java API, you will naturally lose some of the test-automation framework benefits such as HTML reports, parallel execution and JavaScript / configuration. 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). In other words, { a: 1, b: null } is considered equal to { a: 1 } and { a: 1, b: '##null' } will match both cases. When handling XML, you sometimes need to call XPath functions, for example to get the count of a node-set. Here is an example: You can see the structure of the data here: kittens.json. There are a few situations where this comes in handy: As a convenience, you can omit the eval keyword and so you can shorten the above to: This is very convenient especially if you are calling a method on a variable that has been defined such as the karate object, and for general-purpose scripting needs such as UI automation. But you can easily achieve any complex logic by using the JS API. You need to use karate.toJava() to wrap JS functions passed to custom Java code. } This is just a convenience short-cut for waitUntil(locator, "_.textContent.includes('" + expected + "')") since it is so frequently needed. B efore to start talking, How I have learned and show an example How to connect on database with Karate Framework, let me introduce It. A good example of the use of form field for a typical sign-in flow is this OAuth 2 demo: oauth2.feature. 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. This is useful in any situation where you need to concatenate dynamic string fragments to form content such as GraphQL or SQL. But this approach doesnt work when you have to deal with data-entry and fields. This is a good time to deep-dive into JsonPath, which is perfect for slicing and dicing JSON into manageable chunks. Normally we recommend that you keep your re-usable features lightweight - by limiting them to just one Scenario. 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. The keywords def, set, match, request and eval take multi-line input as the last argument. And also note that instead of using the match keyword, you can use karate.match() for very advanced conditional checks. Normally an undefined variable results in nasty JavaScript errors. Experience working in an Agile environment with agile methodologies leveraging Jira And with Karate expressions, you can dive into JavaScript without needing to define a function - and conditional logic is a good example. Here below is the equivalent of the above, done the hard way: The built-in DockerTarget is a good example of how to: Controlling this flow from Java can take a lot of complexity out your build pipeline and keep things cross-platform. 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. Use either the param keyword, e.g. Use the classpath: prefix to load from the classpath instead. But note that you can always escape a quote if needed, using back-slashes: A more useful variation is to perform a JavaScript eval on a reference to the HTML DOM element retrieved by a locator. From a file in the same package. There are examples of calling JVM classes in the section on Java Interop and in the file-upload demo. The business of web-services testing requires access to low-level aspects such as HTTP headers, URL-paths, query-parameters, complex JSON or XML payloads and response-codes. This is best explained in this example: copy.feature. You will typically also match against a specific HTML tag (which is preferred, and faster at run-time). karatelabs /karatePublic Notifications Fork 1.7k Star 6.8k Test Automation Made Simple karatelabs.github.io/karate License MIT license 6.8kstars 1.7kforks Star Notifications Code Issues26 Pull requests0 Actions Projects1 Wiki Security Insights More Code Issues Pull requests Actions Projects Wiki Security Insights karatelabs/karate Dimension before downsampling just karate framework for ui automation Scenario karate.map ( ) for very advanced conditional checks are chain-able alternate.
