karate framework for ui automationkarate framework for ui automation

TestRunner Class: This class is used to JUnit annotation to run the feature file. The need to wait until some text appears is so common, and with this - you dont need to worry about dealing with white-space such as line-feeds and invisible tab characters. function(arg) { Behind the scenes, this sets the HTTP communication read timeout. Technology Partner The BDD syntax popularized by Cucumber is language-neutral, and easy for even non-programmers. for example on a Mac you can use this command: it is recommended that you stick to these defaults, which should suffice for most applications, if you really want, you can change this globally in, even if the driver is instantiated (using the, you can route multiple URL patterns to the same Karate mock-feature, the format of each array-element under. political education Enable HTTPS calls without needing to configure a trusted certificate or key-store. The first option using shared scope should be fine for most projects, but if you want to name space your functions, use isolated scope: You can even move commonly used routines into karate-config.js which means that they become global. Finally, using karate.response.header(name) can be simpler to just get a header value string by name, and it will ignore-case for the name passed as the argument: You would normally only need to use the status keyword. The call keyword provides an alternate way of calling JavaScript functions that have only one argument. It is based on Cucumber and uses the Gherkin Syntax. When you have a runner class in place, it would be possible to run it from the command-line as well. If you dont pass a handler (or it is null), the first message is returned. All we need to do now is to tell Chrome to intercept some URL patterns and use the above mock-server feature-file: The entire example can be found here - and here is a video. 'put', # if you have dynamic keys you can do this, # enable ssl (and no certificate is required), # enable ssl and force the algorithm to TLSv1.2, # time-out if the response is not received within 10 seconds (after the connection is established), # set the uri of the http proxy server to use, https://user:password@zalenium.net/wd/hub, # if this was in karate-config.js, it would apply "globally", # enable X509 certificate authentication with PKCS12 file 'certstore.pfx' and password 'certpassword', # trust all server certificates, in the feature file, // trust all server certificates, global configuration in 'karate-config.js', # add new keys. 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. It will default to { browserName: '' } for convenience where will be chrome, firefox etc. And JSON arrays would become Java List-s. The default is 30000 (30 seconds). This comes in useful because depending on how you organize your files and folders - you can have multiple feature files executed by a single JUnit test-class. {}, """ For Gradle, you simply specify the test which is to be include-d: The big drawback of the approach above is that you cannot run tests in parallel. Valid options are, The number of bits used to encode each pixel, The maximum size on the smallest dimension before downsampling. It is also very useful when we want to run our feature files with some conditions using tags or we want to run specific feature file, all things are control by TestRunner class. This will also do automatically perform a karate.embed() - so that the image appears in the HTML report. Variables set using def in the Background will be re-set before every Scenario. Assertions and HTML reports are built-in, and you can run tests in parallel for speed. } In some cases, for large payloads and especially when the default system encoding is not UTF-8 (Windows or non-US locales), you may run into issues where a java.io.ByteArrayInputStream is encountered instead of a string. You can always use a JavaScript switch case within an eval or function block. But use wisely, because called scripts will now over-write variables that may have been already defined. Look at multipart entity for an example. Example: Get the HTML form-element value. Unlike other API testing tool like Cucumber, JBehave and Specflow, Karate has written all step definitions so we dont have to write it. jbang is a great way for you to install and execute scripts that use Karates Java API on any machine with minimal setup. These examples (all exact matches) can make things more clear: Note that you can alternatively use JsonPath on the left-hand-side: But of course it is preferable to match whole objects in one step as far as possible. The responseCookies variable is set upon any HTTP response and is a map-like (or JSON-like) object. Another good thing that Karate inherits is the nice IDE support for Cucumber that IntelliJ and Eclipse have. But again, you can return a JSON object. You can even remove JSON array elements by index. input: { In fact it may be a good idea to slip doubles instead of integers into some of your tests ! Valid options are, Resemble option to ignore a specific color, Resemble option to override preset tolerances for color and brightness, SSIM grayscale algorithm. You can get really creative and use JS functions to filter data for different needs. 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. If you have other questions or feedback, the comment section is yours. Although all properties in the passed JSON-like argument are unpacked into the current scope as separate named variables, it sometimes makes sense to access the whole argument and this can be done via __arg. Also note that match contains any is possible for JSON objects as well as JSON arrays. This can be a lot simpler than embedded expressions in many cases, and JavaScript programmers will feel right at home. What is Karate Test Framework? When JavaScript executes in Karate, the built-in karate object provides some commonly used utility functions. Now we will create a scenario in feature file. Do look at the documentation and example for configure headers also as it goes hand-in-hand with call. If the request is for /api/*, the first Scenario matches - else the last one is a catch all. Here is a good example in the demos: dynamic-params.feature, The single JSON argument needs to be in the form { field1: { read: 'file1.ext' }, field2: { read: 'file2.ext' } } where each nested JSON is in the form expected by multipart file. But we recommend that you do this only if you are sure that these routines are needed in almost all *.feature files. Also see the option below, where you can data-drive an Examples: table using JSON. Some XPath expressions return a list of nodes (instead of a single node). See this other example for more ideas: dsl.feature. Comprehensive support for different flavors of HTTP calls: You can easily choose features and tags to run and compose test-suites in a very flexible manner. - Karate is BDD testing framework - Developer by Peter Thomas in 2017 (intuit). And you can even handle asynchronous flows such as listening to message-queues. Since it is so easy to dive into Java-interop, Karate does not include any random-number functions, uuid generator or date / time utilities out of the box. This gives you some powerful options, for example you can simulate Ajax and XHR failures, or even replace entire widgets or sections of the page with fake HTML. Please refer to the wiki: Distributed Testing. 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. You can also find a nice visual comparison and explanation here. But the recommended way is to use the karateEnv(name, value) or systemProperty(name, value) API on the parallel-runner. return results.size() == 2 ? input: See the section on reading files - and also this example dynamic-csv.feature, which shows off the convenience of dynamic Scenario Outline-s. playwright) for the start scripts to live. """, """ } """, * def timeLong = call dateStringToLong '2016-12-24T03, # import yaml (will be converted to json), # if the js file evaluates to a function, it can be re-used later using the 'call' keyword (or invoked just like normal js), # the following short-cut is also allowed, # perfect for all those common authentication or 'set up' flows, And request karate.readAsString('classpath, # use only 'ssim' (structural similarity) engine, # always use both 'resemble' and 'ssim' engines but only evaluate the lowest mismatch percentage against our `failureThreshold`, # prefer 'resemble' and fallback to 'ssim' engine only if the resemble mismatch percentage is >= `failureThreshold`, # only consider the comparison as failed when 2% or more pixels are different from the baseline, * configure imageComparison = { failureThreshold, # consider image comparisons that fail due to too many mismatched pixels as passed (especially useful when you are first starting without any baseline images), * configure imageComparison = { mismatchShouldPass, # custom JS function called in Karate HTML image comparison UI when the user clicks the `Rebase` button, """ Note: In POST API request, we have to provide the body (payload). A Java API also exists for those who prefer to programmatically integrate Karates rich automation and data-assertion capabilities. Listing for: Cognizant United States, Cognizant Technology Solutions. Most servers expect the domain to be set correctly like this: Note that you can do the above as a one-liner like this: * cookie({ name: 'hello', value: 'world' }), just keep in mind here that then it would follow the rules of Enclosed JavaScript (not Embedded Expressions). Keep in mind that: Will actually attempt to evaluate the given string as JavaScript within the browser. A common requirement is to build an array with n elements or do something n times where n is an integer (that could even be a variable reference). 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. So you can refer to the response, responseStatus or even responseHeaders if needed. You can use the Visual Studio Karate entension for stepping through and debugging a test. Also make sure that you complete the set up of things like url, param, header, configure etc. ", Karate will wrap the function for you ! Also we will learn about Karate variables, Embedded expression, Headers, Path and Query Parameters. But you can prefix the name with classpath: in which case the root folder would be src/test/java (assuming you are using the recommended folder structure). stop(): Karate will call this method at the end of every top-level Scenario (that has not been call-ed by another Scenario). So you have the following type markers you can use instead of def (or the rarely used text). This is rarely used, unless you are expecting binary content returned by the server. Also see this thread. id: 1 Multi-values are supported the way you would expect (e.g. The BDD syntax popularized by Cucumber is language-neutral, and easy for even non-programmers. Note that embedded expressions will be evaluated even when you read() from a JSON or XML file. please replace RELEASE with the exact version of Karate you intend to use if applicable. function() { using the set keyword. 1. . 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. If you want to dynamically and programmatically determine the tags and features to be included - the API also accepts. Karate has enhanced the Cucumber Scenario Outline as follows: These are best explained with examples. All the methods that return the following Java object types are chain-able. 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. 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). This is convenient for complex nested payloads where you are sure that you only want to check for some values in the various trees of data. Scope of this variable is only on scenario in which it is defined. Also see waits. For an example, refer: upload-multiple-files.feature. }] You can feed an Examples table from a custom data-source, which is great for those situations where the table-content is dynamically resolved at run-time. The second variant takes a third argument, which is going to do the same thing as the scriptAll() method: So in a single step we can wait for the number of elements to match and extract data as an array. Also note that you dont use @Karate.Test for the method, and you just use the normal JUnit 5 @Test annotation. So you could have also done something like: Also refer to the configure keyword on how to switch on pretty-printing of all HTTP requests and responses. And then you have two options. While converting a number to a string is easy (just concatenate an empty string e.g. The special predicate marker #? Notice that in the above example, string values within the table need to be enclosed in quotes. If you want to pretty print a JSON or XML value with indenting, refer to the documentation of the print keyword. If you use the provided ScenarioRuntime.logger instance in your Target code, any logging you perform will nicely appear in-line with test-steps in the HTML report, which is great for troubleshooting or debugging tests. And if you use the following mock, it will actually act as a pass-through proxy - but with the advantage that every single request and response will be emitted to target/karate.log. Given this custom, user-defined Java class: This is how it can be called from a test-script via JavaScript, and yes, even static methods can be invoked: Note that JSON gets auto-converted to Map (or List) when making the cross-over to Java. This example is for Windows, and you can provide the app, appArguments and other parameters expected by the WinAppDriver via the webDriverSession. 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. See also match header which is what you would normally need. In case you were wondering, variables (and even expressions) are supported on the right-hand-side. And the JSON will still be well-formed, and editable in your IDE or text-editor. Karates callonce keyword behaves exactly like call but is guaranteed to execute only once. And you can even chain a retry() before the waitForUrl() if you know that it is going to take a long time: This is very convenient to use for the first element you need to interact with on a freshly-loaded page. Note that karate.signal() (described as part of the listen keyword) will be called internally and the listenResult will be the payload contents of the selected message. subType: { name: 'Smith', deleted: false } 'test1.feature', * def result = responseStatus == 404 ? All arrays no matter the depth will be checked in this way. For example you can get a nice feature coverage report, provided you have a rich set of tags. Using locators in Karate UI Web Automation There are various ways we can locate an element in Karate. Refer to the demos for another example: soap.feature. Karate will scan the log for any string that starts with ws:// and kick things off from there. This is very useful to filter the results that match a desired condition - typically a text comparison. Gives many reasons why one should go for Karate over Selenium. This is important because they are designed to answer the question: does the element exist in the HTML page right now ?. Make sure you configure your source code management system (e.g. That data is used to make yet another request to fetch a JPEG image from e.g. To understand how Karate compares to other UI automation frameworks, this article can be a good starting point: The world needs an alternative to Selenium - so we built one. Here is an example: You can see the structure of the data here: kittens.json. Read the documentation of the stand-alone JAR for more - such as how you can even install custom command-line applications using jbang ! This is preferred because it takes care of situations such as if the value is undefined in JavaScript. This is useful when you ship a JAR file containing re-usable features and JavaScript / Java code and want to default a few variables that teams can inherit from. """, """ Heres a simple recipe to set up this mechanism on your local machine. This method returns a byte array. Karate can run tests in parallel, and dramatically cut down execution time. This is best explained in this example that involves listening to an ActiveMQ / JMS queue. Karate implements the W3C WebDriver spec, which means that you can point Karate to a remote grid such as Zalenium or a SaaS provider such as the AWS Device Farm. { name: 'Smith ', * def result = responseStatus ==?!
