karate framework for ui automation

Full Time position. * match response contains only deep { foo, # and you can use 'contains' the way you'd expect, # some more examples of validation macros, # this is also possible, see the subtle difference from the above, """ Especially since strings can be easily coerced to numbers (and vice-versa) in Javascript, you can combine built-in validators with the self-validation predicate form like this: '#number? The Cucumber JSON format can be also emitted, which gives you plenty of options for generating pretty reports using third-party maven plugins. Note: You can use Jsonpathfinder to find the path of json data. This is a core feature and does not depend on JUnit, Maven or Gradle. Step 1: Create a feature file under src > test > java folder. During variable creation, the gherkin keyword is optional. Refer to karate.tags and karate.tagValues. to save space and speed up report loading), * configure imageComparison = { hideUiOnSuccess, # ignore areas of an image (e.g. If you want to dynamically and programmatically determine the tags and features to be included - the API also accepts. kittens: [ He created Karate to address some of the issues of Selenium. This should make it clear why Karate does not provide out of the box support for any particular HTTP authentication scheme. [ deleted: false Theres also a cross-platform stand-alone executable for teams not comfortable with Java. JavaScript Functions are also native. name: 'John', For convenience, Karate assumes by default that the executable name is playwright and that it exists in the System PATH. 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). It uses the Gherkin syntax, made popular by Cucumber, which is language-neutral, easy to use even for non-programmers and is centered on Behavior Driven Development (BDD). 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. 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. Refer to the demo karate-config.js for an example and how the demo.server.port system-property is set-up in the test runner: TestBase.java. Rarely used, but sometimes for only some parts of your test - you need to tell the browser to wait for a very slow loading page. Here is an example of waiting for a search box to appear after a click(), and note how we re-use the Element reference returned by waitFor() to proceed with the flow. Remove elements from a list in karate? In below image in get demo 4 scenario I have added few assertions. You simply roll your own. To avoid flaky tests, use waitForUrl(). If the second HTTP call above expects headers to be set by my-headers.js - which in turn depends on the authToken variable being updated, you will need to duplicate the line * configure headers = read('classpath:my-headers.js') from the caller feature here as well. all the key-value pairs are added to the HTTP headers. The above logic can actually be replaced with Karates built-in short-cut - which is waitForResultCount() Also see waits. "a": 1, A very useful capability is to be able to check that an array contains an object that contains the provided sub-set of keys instead of having to specify the complete JSON - which can get really cumbersome for large objects. Note that #present and #notpresent only make sense when you are matching within a JSON or XML context or using a JsonPath or XPath on the left-hand-side. Expressions are evaluated using the embedded JavaScript engine. Ping me Now! You can also use JSON to set multiple query-parameters in one-line using params and this is especially useful for dynamic data-driven testing. In below image we can see I have created feature file. 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). function(arg) { If you are new to programming or test-automation, refer to the options for IDE support and the official IntelliJ plugin is recommended. You can read more about the Given-When-Then convention at the Cucumber reference documentation. 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 note that you can use the negative form of a tag selector: ~@region=GB. Calling any Java code is that easy. For example if you have the JUnit class in the com.mycompany package, *.feature files in com.mycompany.foo and com.mycompany.bar will also be run. A special case of embedded expressions can remove a JSON key (or XML element / attribute) if the expression evaluates to null. The usage of karate.write() here is just an example, you can use JS or Java interop as needed. Now we will create a scenario in feature file. 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. when a string coming from an external process is dynamic - and whether it is JSON or XML is not known in advance, see, get the value of a variable by name (or JsonPath expression), if not found - this returns, returns only the keys of a map-like object, log to the same logger (and log file) being used by the parent process, logging can be suppressed with, access to the Karate logger directly and log in debug. Instead you would typically use the match keyword, that is designed for performing powerful assertions against JSON and XML response payloads. Step 5: Now we can run this TestRunner class as JUnit. 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. As a convenience, to reset the value to what was initially set, you can call timeout() with no argument: Only applies to WebDriver based driver sessions, and useful in case you need the session id to download any test-reports / video etc. Combined with Docker, headless Chrome and Karates parallel-execution capabilities - this simple start() and stop() lifecycle can effectively run web UI automation tests in parallel on a single node. A JavaScript function or Karate expression at runtime has access to a utility object in a variable named: karate. To force a null value, wrap it in parentheses: An alternate way to create data is using the set multiple syntax. So if you tried to re-use the same feature but with multiple arguments, things will not work as you expect. Note that you would typically want to use the @ignore tag for such cases. Example: Get the HTML form-element value. So the above could be re-written as follows: It is worth repeating that the above can be condensed into 2 lines. But some troublesome parts of your flow will require re-tries, and this is where the retry() API comes in. And you can consider a driverTarget approach for complex needs such as using a Docker container for CI. And steps that follow should logically be in the Then form. If you need to actually do something with each returned Element, see locateAll() or the option below. If your XPath is dynamic and has to be formed on the fly perhaps by using some variable derived from previous steps, you can use the karate.xmlPath() helper: You can refer to this file (which is part of the Karate test-suite) for more XML examples: xml-and-xpath.feature. A very powerful variation of waitUntil() takes a full-fledged JavaScript function as the argument. It can also be argued that the # symbol is easy to spot when eyeballing your test scripts - which makes things more readable and clear. and & will be automatically inserted. But there is a twist ! The BDD syntax popularized by Cucumber is language-neutral, and easy for even non-programmers. Learn more. The default setting for the max retry-attempts is 3 with a poll interval of 3000 milliseconds (3 seconds). @smoke @module=one @module=two etc. # note how we return null to keep looping, """ One limitation is that you cannot use double-quotes within these expressions, so stick to the pattern seen below. They use JSON to build the relevant parts of the HTTP request. You could get by by renaming the file-extension to say *.txt but an alternative is to use the karate.readAsString() API. The karate-demo has an example showing various ways to configure or set headers: headers.feature. Features API and UI automation 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. In rare cases, you may want to check what the type of the response is and it can be one of 3 different values: json, xml and string. There should always be karate-config.js in the root folder, even if you dont have any common config. Important: If you attempt to build a URL in the form ?myparam=value by using path the ? When re-running tests in development mode and when your test suite depends on say an Authorization header set by karate.callSingle(), you can cache the results locally to a file, which is very convenient when your auth token is valid for a period of a few minutes - which typically is the case. var jd = new JavaDemo(); But use wisely, because called scripts will now over-write variables that may have been already defined. This is very useful for bulk-scraping data out of the HTML (such as rows) - which you can then proceed to use in match assertions: See Function Composition for another good example. Make sure you configure your source code management system (e.g. Also look at the section on commonly needed utilities for more ideas. And if you do this within a Background: section, it would apply to all Scenario: sections within the *.feature file. Note that for. Step 4: Run this feature file and get the report in target > karate-reports > karate-summary.html. So you can do things like right-click and run a *.feature file (or scenario) without needing to use a JUnit runner.
