Step 3: Add steps to run a sample GET API request. Karate makes re-use of payload data, utility-functions and even other test-scripts as easy as possible. Karate supports JUnit 5 and the advantage is that you can have multiple methods in a test-class. One indicator of a good automation framework is how much work a developer needs to do in order to perform any automation action - such as clicking a button, or retrieving the value of some HTML object / property. 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. 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. We will use this page: https://www.seleniumeasy.com/test/dynamic-data-loading-demo.html - as an example. All the methods that return the following Java object types are chain-able. Get all my courses for USD 5.99/Month - https://bit.ly/all-courses-subscriptionIn this Karate Tutorial, we will learn about webelement functions in Karate, l. Here is an example that you can try: The driver.inputFile() can take an array or varargs as the second argument. In addition to boxes are directly supported like this, so internally a find('select') is chained automatically: One reason why you would need near() is because an Karate is the only open-source tool to combine API test-automation, mocks, performance-testing and even UI automation into a single, unified framework. path to file containing the trust chain for your server certificate. You can replace the values of com.mycompany and myproject as per your needs. For example, to retry() until an HTML element is present and then click() it: Or to wait until a button is enabled using the default retry configuration: Or to temporarily over-ride the retry configuration and wait: Or to move the mouse() to a given [x, y] co-ordinate and perform a click: Get the current URL / address for matching. The recipe for doing this when running Maven from the command line is: You can refer to the documentation of the Maven Surefire Plugin for alternate ways of achieving this, but the argLine approach is the simplest and should be more than sufficient for your Continuous Integration or test-automation needs. 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. if there is no matching tag - that the Examples without a tag will be executed. Karates native support for JSON means that you can assign parts of a JSON instance into another variable, which is useful when dealing with complex response payloads. The default is 30000 (30 seconds). Note that Content-Type had to be enclosed in quotes in the JSON above because the - (hyphen character) would cause problems otherwise. More examples are available that showcase various ways of parameter-izing and dynamically manipulating SOAP requests in a data-driven fashion. Listing for: Cognizant United States, Cognizant Technology Solutions. For some more examples check test-outline-name-js.feature. But some troublesome parts of your flow will require re-tries, and this is where the retry() API comes in. Note that there is a karate.fail() API that may be handy when you want to fail a test after advanced / conditional checks. If this is the first instance in a test, this step also initializes the driver instance for all subsequent steps - using what is configured. locateAll() can take a second argument which has to be a JavaScript predicate function, that returns a boolean true or false. It is worth pointing out that JSON is a first class citizen of the syntax such that you can express payload and expected data without having to use double-quotes and without having to enclose JSON field names in quotes. You can potentially include the steps of deploying (and un-deploying) the application-under-test using this approach - but probably the top-level JUnit test-suite would be the right place for those. This is a very powerful way to generate test-data without having to load a large number of data rows into memory. And there is another example in the karate-demos: schema.feature where you can compare Karates approach with an actual JSON-schema example. name: 'Billie', { We can use this with param in And condition like below. The first takes a single boolean argument - whether to accept or cancel. Job specializations: IT/Tech. 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. 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. returns the operating system details as JSON, for e.g. 1 [karate]: Karate UI Automation: Unable to launch the browser. 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. But take a look at how Karate can loop over a *.feature file for each object in a JSON array - which gives you dynamic data-driven testing, if you need it. Bloating your configuration can lead to loss of performance, and maintainability may suffer. In fact Gherkin supports the catch-all symbol * - instead of forcing you to use Given, When or Then. Listed on 2023-03-01. When you have a large and complex project, you will end up with a few data files (e.g. First, you can maintain a JSON map of your application locators. Step 4: Run this feature file and get the report in target > karate-reports > karate-summary.html. """, """ That said, there is some benefit to re-use of just locators and Karates support for JSON and reading files turns out to be a great way to achieve DRY-ness in tests. Cucumber has a limitation where Background steps are re-run for every Scenario. name,type In below image we can see I have created feature file. ] But one pattern that you should be aware of is that JSON is actually a great data-structure for looking up data. Note that for. This can be a huge time-saver ! Another (simple) example of a custom Target you can use as a reference is this one: karate-devicefarm-demo - which demonstrates how Karate can be used to drive tests on AWS DeviceFarm. If you find yourself juggling multiple tags with logical AND and OR complexity, refer to this Stack Overflow answer. Billie Heres how it works: Here is a contrived example that uses match each, contains and the #? Karate can run tests in parallel, and dramatically cut down execution time. 2 PUT method in HTTP is used to update the resources on the server. Karate framework is developed by Peter Thomas employed at Intuit. This is best explained in this example: copy.feature. In below image in get demo 4 scenario I have added few assertions. Note that forcing Scenario-s to run in a particular sequence is an anti-pattern, and should be avoided as far as possible. If you want to perform API testing but you dont have knowledge of any programming language then you should choose Karate framework to perform API testing. Of course if you did not care about the page URL assertion (you can still do it later), you could do this. A handler function is needed only if you have to ignore some incoming traffic and stop the wait when a certain payload arrives. This is important because they are designed to answer the question: does the element exist in the HTML page right now ?. All-in-one framework that includes parallel-execution, HTML reports, environment-switching, and CI integration. As a convenience, cookies from the previous response are collected and passed as-is as part of the next HTTP request. Note that the parser is lenient so that you dont have to enclose all keys in double-quotes. This is so that you can mix expressions into text replacements as shown below. or anything wrapped in parentheses which will be evaluated as JavaScript - e.g. For more complex functions you are better off using the multi-line doc-string approach. JavaScript Functions are also native. The final piece of the puzzle is to set up a batch file to start the server: The exec is important here so that Karate can stop the node process cleanly. The responseCookies variable is set upon any HTTP response and is a map-like (or JSON-like) object. If you really need to have an empty body, you can use an empty string as shown below, and you can force the right Content-Type header by using the header keyword. Here is an example: You can see the structure of the data here: kittens.json. playwright) for the start scripts to live. If you get stuck and ask a question on Stack Overflow, make sure you provide a cURL command that works - or else it would be very difficult for anyone to troubleshoot what you could be doing wrong. This is especially useful when capturing screenshots during tests and comparing against baseline images that are known to be correct. } before you fire the method. Bob,Wild This video explain how to do UI Automation using Karate DSL.If you like this video please do subscribe to my channel and keep watching ! But since you can express a list of data-elements as a JSON array - even these XPath expressions can be used in match statements. And as shown in the example below, having text in-line is useful especially when you use the Scenario Outline: and Examples: for data-driven tests involving Cucumber-style place-holder substitutions in strings. You can see how it can be re-used anywhere to scrape the contents out of any HTML tabular data, and all you need to do is supply the locator that matches the elements you are interested in. A set of real-life examples can be found here: Karate Demos. A good example of the use of form field for a typical sign-in flow is this OAuth 2 demo: oauth2.feature. And with the its latest update, Karate also supports UI test automationmaking it a true, end-to-end unified testing framework . In real-life flows, you may need to pass cookies from the browser to the Karate HTTP client, so that you can simulate any flows needed after this step. }] Keep in mind that you should be able to comment-out a Scenario or skip some via tags without impacting any others. You normally never need to use this in a test, Karate will close the browser automatically after a Scenario unless the driver instance was created before entering the Scenario. Karate is the only open-source tool to combine API test-automation, mocks, performance-testing and even UI automation into a single, unified framework. Note how we unpack the kittens and use it to data drive the Scenario Outline. the NOT operator e.g. The karate-demo has an example showing various ways to configure or set headers: headers.feature. So if you have a Feature with multiple Scenario-s in it - they will execute in parallel, and even each Examples row in a Scenario Outline will do so ! On the other hand, if you are expecting a variable in the Background to be modified by one Scenario so that later ones can see the updated value - that is not how you should think of them, and you should combine your flow into one scenario. German or ISO-8859-15. { """, # note the 'text' keyword instead of 'def', """ to save space and speed up report loading), * configure imageComparison = { hideUiOnSuccess, # ignore areas of an image (e.g. Simple arrays of strings or numbers can be stripped of duplicates using karate.distinct(). Observe the usage of Scenario Outline: instead of Scenario:, and the new Examples: section. It can be easily inspected or used in expressions. Other UI automation frameworks spend a lot of time encouraging you to follow a so-called Page Object Model for your tests. Look at how the path did not need to be specified for the second HTTP get call since /cats is part of the url. return 'this text will be displayed to the user when they click the rebase button' And for dealing with binary content - see bytes. Karate provides a far more simpler and more powerful way than JSON-schema to validate the structure of a given payload. There is also a variant of Scenario called Scenario Outline along with Examples, useful for data-driven tests. API tests are written in BDD (Behaviour Driven Development) Using Gherkin syntax. 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. 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). The key should not be within quotes. Create Karate Framework Sample Project Step 1: Open Eclipse Step 2: File > New > Maven Project Step 3: Provide the project details and create project Step 4:Add Maven dependencies in pom.xml Karate core Karate Apache Karate Junit4 Step 5:Saved the Project. This is very useful to filter the results that match a desired condition - typically a text comparison. Based on the above details, you should be able to come up with a custom strategy to connect Karate to Playwright. return 'this text will be displayed above the image comparison config\n' + customConfigJson Instead you would typically use the match keyword, that is designed for performing powerful assertions against JSON and XML response payloads. So you can use Karate to set-up data via API calls, then run the UI test-automation, and finally again use Karate to assert that the system-state is as expected. It is actually a transpose of the table approach, and can be very convenient when there are a large number of keys per row or if the nesting is complex. And there is no more worrying about Maven profiles and whether the right *.properties file has been copied to the proper place. 5 entityState: "ACTIVE" All you need is available in the karate-core artifact. If you find yourself struggling to write dynamic JsonPath filters, look at karate.filter() as an alternative, described just below. Learn more. To avoid flaky tests, use waitForUrl(). hero(name: "") { If you have trouble with boxes, try using script() to execute custom JavaScript within the page as a work-around. # we compose a function using another function (the one above), """ Since paths are expected at the end of the command-line options - if you want to only over-ride tags, use the = sign to make argument values clear. If you want to use JUnit 4, use the karate-junit4 Maven dependency instead of karate-junit5. Important: do not use the @RunWith(Karate.class) annotation. a sibling Docker container or a Chrome browser in a different machine) you might need to configure DockerTarget with the remoteHost and/or useDockerHost properties. Notice that in the above example, string values within the table need to be enclosed in quotes. ] 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). You can easily assert that all expected elements are present, even in nested parts of your JSON - while doing a match on the full payload. What started as a powerful, scriptable framework combining API and UI test automation, is adopted as a best-practice today - in teams around the world. For every HTTP request made from Karate, the internal flow is as follows: This makes setting up of complex authentication schemes for your test-flows really easy. Once you get a result, you typically use it to set global variables. You get to choose how to manage your environment-specific configuration values such as user-names and passwords. But guess what - this example is baked into a Karate API, see waitForText(). But there is a twist ! The above example actually makes two HTTP requests - the first is a standard sign-in POST and then (for illustrative purposes) another HTTP call (a GET) is made for retrieving a list of projects for the signed-in user, and the first one is selected and added to the returned auth token JSON object. The {} and {^} locator-prefixes are designed to make finding an HTML element by text content super-easy. The above example can be made more simpler with the use of call (or callonce) without a def-assignment to a variable, and is the recommended pattern for implementing re-usable authentication setup flows. Valid options are, The number of bits used to encode each pixel, The maximum size on the smallest dimension before downsampling. 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). Also Karate will call the executable with three arguments in this order: So this is how you can communicate your cross-browser config from your Karate test to the executable. It is one of the great tool for API testing. var sdf = new SimpleDateFormat('yyyy/MM/dd'); You simply roll your own. Karate can read *.csv files and will auto-convert them to JSON. The last boolean argument is whether the karate-config.js should be processed or not. But always use the driver keyword when you start a test and you can choose to prefer that shorter form in general. But since the optional() API is designed to handle the case when a given locator does not exist, you can write some very concise tests, without needing to examine the returned object from waitForAny(). As a rule of thumb, prefer match over assert, because match failure messages are more detailed and descriptive. But normally a match statement is preferred unless you want a really descriptive error message. This also works as a getter to get the current window dimensions. A common requirement is to pass dynamic parameter values via the command line, and you can use the karate.properties['some.name'] syntax for getting a system property passed via JVM options in the form -Dsome.name=foo. Note that url and request are not allowed as variable names. But first, a special short-cut for array validation needs to be introduced: This in-line short-cut for validating JSON arrays is similar to how match each works. scriptAll() can take a third argument which has to be a JavaScript predicate function, that returns a boolean true or false. Important: If you attempt to build a URL in the form ?myparam=value by using path the ? And as a convenience, whatever object is returned, can be re-used in future steps. You can organize multiple common utilities into a single re-usable feature file as follows e.g. @smoke @module=one @module=two etc. If you really need to re-use a Java function, see Java Function References. Ideally it should return pure JSON and note that you always get a deep clone of the cached result object. 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. Instantiating a Java class and using this in a test is easy (see example): Since karate-config.js is processed for every Scenario, you can use a singleton instead of calling new every time. If the machine where you are running Karate is not the same as your target host (e.g. 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. 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. Also see the option below, where you can data-drive an Examples: table using JSON. Heres a reminder that the #notpresent marker can be mixed into an equality match (==) to assert that some keys exist and at the same time ensure that some keys do not exist: The ! The BDD syntax popularized by Cucumber is language-neutral, and easy for even non-programmers. Karate has a built-in implementation for Docker (DockerTarget) that supports 2 existing Docker images out of the box: To use either of the above, you do this in a Karate test: Or for more flexibility, you could do this in karate-config.js and perform conditional logic based on karate.env. Very handy for waiting for an expected URL change and asserting if it happened. If you have one pre-started, you need to use the playwrightUrl driver config. Add the plugin to the / section of your pom.xml if not already present: If you want to use JUnit 4, use the karate-junit4 Maven dependency instead of karate-junit5. It may be easier for you to use the Karate Maven archetype to create a skeleton project with one command. A very rare need is to be able to convert a string which happens to be in YAML form into JSON, and this can be done via the yaml type cast keyword. function (customConfigJson, config) { This is especially relevant when manipulating GraphQL queries - because although they look suspiciously like JSON, they are not, and tend to confuse Karates internals. left: 1085, The above methods return a chainable Finder instance. And if you have a Scenario Outline, this happens for every row in the Examples. Read the documentation of the stand-alone JAR for more - such as how you can even install custom command-line applications using jbang ! Karate is the only open-source tool to combine API test-automation, mocks, performance-testing and even UI automation into a single, unified framework. "hotels": [ Watch launch recording here. The scenario expression result is expected to be an array of JSON objects. If you are new to programming or test-automation, refer to the options for IDE support and the official IntelliJ plugin is recommended. See karate.callSingle().
