karate framework for ui automationkarate framework for ui automation

physics One pattern you can adopt is to create a factory method that returns a Java function - where you can easily delegate to the logic you want. 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. You can then skip the next few sections, as the pom.xml, recommended directory structure, sample test and JUnit 5 runners - will be created for you. The not equals operator != works as you would expect: You typically will never need to use the != (not-equals) operator ! Defining the request is mandatory if you are using an HTTP method that expects a body such as post. This is a problem especially for expensive, time-consuming HTTP calls, and this has been an open issue for a long time. File-upload is supported natively only by type: chrome. The primary classes are described below. It can be used instead of waitForUrl() and you can still perform a page URL assertion as seen below. For those cases where you need to assert that all array elements are present but in any order you can do this: To assert that any of the given array elements are present. Karate was based on Cucumber-JVM until version 0.8.0 but the parser and engine were re-written from scratch in 0.9.0 onwards. if you are using Karate to create a Java application, LOGBack will look for logback.xml. This is a normal JUnit 4 test class ! Here is a summary of what the different shapes mean in Karate: There is no need to prefix variable names with $ on the left-hand-side of match statements because it is implied. And yes, variables can come from global config. For performance reasons, you can implement enableForUri() so that this activates only for some URL patterns. 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. The BDD syntax that Cucumber has gone on to popularize is language-neutral, which makes it easy for nonprogrammers as well. Note how karate.set() and karate.remove() below are used directly as a script statement. EndPoint: https://www.kloia.com/ blog?page=2, Given url https://www.kloia.com/ Note that the set (multiple) keyword can build complex, nested JSON (or XML) from scratch in a data-driven manner, and you may not even need to read from files for many situations. So you can compare 2 JSON (or XML) payloads if you wanted to: If you are wondering about the finer details of the match syntax, the Left-Hand-Side has to be either a. sleep time in milliseconds, relevant only for. Note that there is a top-level config flag for headless mode. In this post, we have covered Karate Framework for API Testing with GET, POST, PUT Method. They use JSON to build the relevant parts of the HTTP request. "c": 3 You can imagine how this greatly simplifies setting up tests for boundary conditions. In such cases, you can use waitForUrl(). You can also compare images using Karate path prefixes (e.g. or $[. JSON arrays), see. For example, where it is easy (or you already have a reference) to locate some element and you want to use that as a base to perform something on some other element which may not have a unique id or css / XPath locator. If you want to keep the level as DEBUG (for HTML reports) but suppress logging to the console, you can comment out the STDOUT root appender-ref: Or another option is to use a ThresholdFilter, so you still see critical logs on the console: If you want to exclude the logs from your CI/CD pipeline but keep them in the execution of your users in their locals you can configure your logback using Janino. When you have a large and complex project, you will end up with a few data files (e.g. You can lock down the fact that you only want to execute the single JUnit class that functions as a test-suite - by using the following maven-surefire-plugin configuration: Note how the karate.options can be specified using the configuration. We can return JSON and even an image using a mock like this: Refer to the Karate test-doubles documentation for details. Important: If you attempt to build a URL in the form ?myparam=value by using path the ? Refer to the section on XPath Functions for examples of advanced XPath usage. You will typically also match against a specific HTML tag (which is preferred, and faster at run-time). 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. So most of the time this would be sufficient: Since it will result in the following request to the WebDriver /session: But in some cases, especially when you need to talk to remote driver instances, you need to pass specific shapes of JSON expected by the particular implementation - or you may need to pass custom data or extension properties. You need to call a method on the driver object directly. One of these is the use of a Gherkin file, which describes the tested feature. If you face issues such as class not found, just pull in the karate-core dependency, and use the all classifier in your pom.xml (or build.gradle). you can use pure JsonPath expressions (notice how this is different from the above), # and even append to json arrays (or create them automatically), # and for match - the order of keys does not matter, # you can ignore fields marked with '#ignore', # you can even set whole fragments of xml, """ API API POST API abcd : : Simple, clean syntax that is well suited for people new to programming or test-automation. The approach in this section is more suited for troubleshooting in dev-mode, using your IDE. function(x, y, i) { Variables set using def in the Background will be re-set before every Scenario. Also note how the Background will run 4 times (twice per Scenario). And you can easily assert that the data is as expected by comparing it with another JSON or XML object. You could even have all the steps start with When and Karate wont care. Unlike other API testing tool like Cucumber, JBehave and Specflow, Karate has written all step definitions so we dont have to write it. It will default to { browserName: '' } for convenience where will be chrome, firefox etc. Heres how it works for XML: This comes in useful in some cases - and avoids needing to use the set keyword or JavaScript functions to manipulate JSON. A callonce is ideally used for only pure JSON. As you can imagine, this can handle un-predictable dialogs, advertisements and the like. API tests are written in BDD (Behaviour Driven Development) Using Gherkin syntax. By default, the value of karate.env when you access it within karate-config.js - would be null. 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. For advanced users, Karate supports being able to query for tags within a test, and even tags in a @name=value form. Only one JSON argument is allowed, but this does not limit you in any way as you can use any complex JSON structure. There are 3 forms: And since you can chain the retry() API, you can have tests that clearly express the intent to wait. Only one keyword sets up UI automation in Karate, typically by specifying the URL to open in a browser. To signal the end of the data, just return null. The special predicate marker #? Note how the fake response.json is tiny compared to the real JSON, because we know that only a few data-elements are needed for the UI to work in this case. So you have the following type markers you can use instead of def (or the rarely used text). Other UI automation frameworks spend a lot of time encouraging you to follow a so-called Page Object Model for your tests. You can easily get the value of the current environment or profile, and then set up global variables using some simple JavaScript. Other errors could be a java.net.URISyntaxException and match not working as expected because of special or foreign characters, e.g. For example if you have HTML like this: To click on the checkbox, you just need to do this: By default, the HTML tag that will be searched for will be input. Cucumber has a limitation where Background steps are re-run for every Scenario. Calling any Java code is that easy. driver.getTitle() becomes driver.title. Another example is dogs.feature - which actually makes JDBC (database) calls, and since the data returned from the Java code is JSON, the last section of the test is able to use match very effectively for data assertions. 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. Here is an example: Here above, you see the karate.log(), karate.env and karate.configure() helpers being used. Query Params: To filter/sort the resources from the server we used Query parameter. This means that you can combine them to concisely express certain types of intent - without having to repeat the locator. If you really want a long-running flow that combines steps from multiple features, you can make a call to each of them from the single top-level Scenario. Observe how you can mix different locator types, because they are all just string-values that behave differently depending on whether the first character is a / (XPath), {} (wildcard), or not (CSS). The steps which are defined under background will run before each and every scenario for a feature file. Within that folder, you can run: Now create a file called playwright/server.js with the following code: The main thing here is that the server URL should be logged to the console when it starts. 3+ years Selenium, Cucumber, BDD, Gherkin Karate or RestAssured framework, Jenkins and SonarCube . You can see a demo video here. Watch launch recording here. Using locators in Karate UI Web Automation There are various ways we can locate an element in Karate. In below image we can see I have created feature file. If you want, you could even create nested chunks of JSON that name-space your config variables. You need to use karate.toJava() to wrap JS functions passed to custom Java code. Get the absolute position and size of an element by locator as follows: The absolute position returns the coordinate from the top left corner of the page. This applies to JS functions as well: These heavily commented demo examples can help you understand shared scope better, and are designed to get you started with creating re-usable sign-in or authentication flows: Once you get comfortable with Karate, you can consider moving your authentication flow into a global one-time flow using karate.callSingle(), think of it as callonce on steroids. Compared this with other front end au. Karate can split a test-suite across multiple machines or Docker containers for execution and aggregate the results. 2. The BDD syntax popularized by Cucumber is language-neutral, and easy for even non-programmers. 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. You end up with a decent approximation of BDD even though web-services by nature are headless, without a UI, and not really human-friendly. The rest can also be used even in primitive data matches like so: If two cross-hatch # symbols are used as the prefix (for example: ##number), it means that the key is optional or that the value can be null. It is sometimes useful to be able to check if a key-value-pair does not exist. Once you get a result, you typically use it to set global variables. So it is recommended that you directly use a Java Function when possible instead of using the karate.toJava() wrapper as shown above. Karate has an elegant approach to handling any action such as click() that results in a new page load. 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. See the section on reading files - and also this example dynamic-csv.feature, which shows off the convenience of dynamic Scenario Outline-s. 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. The method signature of the assertTrue has flipped around a bit. sorts the list using the provided custom function called for each item in the list (and the optional second argument is the item index) e.g. Here are the few things you need to know. Another good thing that Karate inherits is the nice IDE support for Cucumber that IntelliJ and Eclipse have. If you are familiar with Cucumber (JVM), you may be wondering if you need to write step-definitions. You signal that a submit is expected by calling the submit() function (which returns a Driver object) and then chaining the action that is expected to trigger a page load. Note that Karate will fail the test if the waitUntil() returned false - even after the configured number of re-tries were attempted. This is very common in the world of Maven users and keep in mind that these are tests and not production code. You get to choose how to manage your environment-specific configuration values such as user-names and passwords. You could get by by renaming the file-extension to say *.txt but an alternative is to use the karate.readAsString() API. The variable state after feature execution would be returned as a Map. If you are just trying to pre-define schema snippets to use in a fuzzy-match, you can use enclosed Javascript to suppress the default behavior of replacing placeholders. For some SPAs (Single Page Applications) the detection of a page load may be difficult because page-navigation (and the browser history) is taken over by JavaScript. In this Karate Framework Tutorial, We are going to create the Own Karate API Testing Automation Framework, We will use the Person APIs (with JSON Server). Here we want to call a file only if a condition is satisfied: Or if we dont care about the result, we can eval an if statement: And this may give you more ideas. For those who may prefer YAML as a simpler way to represent data, Karate allows you to read YAML content from a file - and it will be auto-converted into JSON. The .graphql and .gql extensions are also recognized (for GraphQL) but are handled the same way as .txt and treated as a string. There are two things that can happen to the returned value. For example: And similarly for XML and XPath, / represents the response. 1. You can find a lot more references, tutorials and blog-posts in the wiki. See this other example for more ideas: dsl.feature. Ideally it should return pure JSON and note that you always get a deep clone of the cached result object. 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 last row in the table is a little different from the rest, and this short-cut form is the recommended way to validate the length of a JSON array. You can replace the values of com.mycompany and myproject as per your needs. and & will be automatically inserted. If you have a custom implementation of a Target, you can easily construct any custom Java class and pass it to configure driverTarget. Note that locate() will fail the test if the element was not found. Since Karate combines API testing capabilities, you can sign-in to your SSO store via a REST end-point, and then drop cookies onto the browser so that you can bypass the user log-in experience. : * param myparam = 'value' or url: * url 'http://example.com/v1?myparam'. In addition, it also supports mocks, performance testing, and Mobile test Automation with other inbuilt features You can see what the result looks like here. You can also use driver.startRecordingScreen() and driver.stopRecordingScreen(), and both methods take recording options as JSON input. Step 3: Provide the project details and create project, Step 4: Add Maven dependencies in pom.xml. Or - if a call is made without an assignment, and if the function returns a map-like object, it will add each key-value pair returned as a new variable into the execution context. # reset to defaults for the rest of the test //www.seleniumeasy.com/test/dynamic-data-loading-demo.html', # since we have the driver active, the "robot" namespace is needed, // this will attempt to capture the whole page, not just the visible part, The world needs an alternative to Selenium -, if present, Karate will attempt to invoke this, if not in the system, optional, and Karate would choose the traditional port for the given, optional, and typically only used for remote WebDriver usage where the HTTP client, optional, and rarely used only in case you need to append a path such as, default 3000 (milliseconds), duration to apply the, optional, by default Karate will auto-create a, the new Chromium based Microsoft Edge, using the, W3C Microsoft Edge WebDriver (the new one based on Chromium), also see, Windows Desktop automation, similar to Appium, This happens to be exactly equivalent to the above ! 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). 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. This means that as long as the token on file is valid, you can save time by not having to make the one or two HTTP calls needed to sign-in or create throw-away users in your SSO store. var foo = function(v){ return v * v }; In situations where you start an (embedded) application server as part of the test set-up phase, a typical challenge is that the HTTP port may be determined at run-time. Standard JavaScript syntax rules apply, but the right-hand-side should begin with the function keyword if declared in-line. Note that there is a karate.fail() API that may be handy when you want to fail a test after advanced / conditional checks. You can always use a JavaScript switch case within an eval or function block. Ideally you should return only pure JSON data (or a primitive string, number etc.). And if you have a Scenario Outline, this happens for every row in the Examples. 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. 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. See waitForUrl() instead of submit().
