Of course it is an option to have Karate tests in a separate stand-alone maven project and folder, while still being in the same Git repository. { Since templates can be loaded using the classpath: prefix, you can even re-use templates across your projects via Java JAR files. any valid JavaScript expression, and variables can be mixed in, another example: equivalent to the above, JavaScript function invocation, Pretty print the request payload JSON or XML with indenting (default, Pretty print the response payload JSON or XML with indenting (default. Remove elements from a list in karate? This is for evaluating arbitrary JavaScript and you are advised to use this only as a last resort ! Karate has the following short-cut symbols designed to be mixed into embedded expressions: For completeness, == and != also belong in the above list. JsonPath and Karate expressions are not supported. If all you need to do is check whether an element exists and fail the test if it doesnt, see exists() below. And as a convenience, whatever object is returned, can be re-used in future steps. So you can do things like right-click and run a *.feature file (or scenario) without needing to use a JUnit runner. 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. Here is a sample logback-test.xml for you to get started. 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. Here is an example: Any Karate variable will be available to the template, which is users.html in this example. if you acquired a string from some external source, or if you generated JSON (or XML) by concatenating text or using replace, you may want to convert a string to JSON and vice-versa. For some more examples check test-outline-name-js.feature. Use a variable in the called feature instead, for e.g. Hard page reload, which will clear the cache. Refer to JsonPath short-cuts for a detailed explanation. The default setting for the max retry-attempts is 3 with a poll interval of 3000 milliseconds (3 seconds). You can start a Driver instance programmatically and perform actions and assertions like this: You can find the complete example here. If you want to point to a real file, use the file: prefix. You dont have to compile code. It can be used instead of waitForUrl() and you can still perform a page URL assertion as seen below. e.g. name: 'Billie', Then use the header keyword to do a custom over-ride if needed. Note that you would typically want to use the @ignore tag for such cases. { 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. With the Karate framework, testers without a programming background can perform tests more easily. What is Robot Class in Selenium and How to Use it? The approach in this section is more suited for troubleshooting in dev-mode, using your IDE. Internally, Karate will auto-convert JSON (and even XML) to Java Map objects. karate.appendTo(idxs, i); Valid options are, The number of bits used to encode each pixel, The maximum size on the smallest dimension before downsampling. 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. That said, if you really need to implement conditional checks, this can be one pattern: And this is another, using karate.call(). So you get the best of both worlds: the elegance of JSON to express complex nested data - while at the same time being able to dynamically plug values (that could even be other JSON or XML trees) into a template. 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. Before we get to the HTTP keywords, it is worth doing a recap of the various shapes that the right-hand-side of an assignment statement can take: They are url, path, request, method and status. It returns the Element representation of whichever element was found first, so that you can perform conditional logic to handle accordingly. } The responseCookies variable is set upon any HTTP response and is a map-like (or JSON-like) object. If you want to use JUnit 4, use the karate-junit4 Maven dependency instead of karate-junit5. 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. For convenience, you can have multiple expressions separated by commas, so this is the recommended pattern: Similar to assert, the expressions on the right-hand-side of a print have to be valid JavaScript. . Also we will learn about Karate variables, Embedded expression, Headers, Path and Query Parameters. 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 ! Do look at the documentation and example for configure headers also as it goes hand-in-hand with call. right: 1496 You can easily select (double-click), copy and paste this file: URL into your browser address bar. You can imagine how this greatly simplifies setting up tests for boundary conditions. The keywords Given When Then are only for decoration and should not be thought of as similar to an if - then - else statement. The value column can take expressions, even XML chunks. That said, if you want to stick to JavaScript, but find yourself accumulating a lot of helper functions that you need to use in multiple feature files, the following pattern is recommended. For more details check this link- Embedded Expression. An advanced option is where the scenario expression returns a JavaScript generator function. return 'this text will be displayed to the user when they click the rebase button' } For example: So this is just for convenience and readability, using configure driver can do the same thing like this: This design is so that you can use (and data-drive) all the capabilities supported by the target driver - which can vary a lot depending on whether it is local, remote, for desktop or mobile etc. Also see value(locator, value) and clear(). It will be initialized only after the driver keyword has been used to navigate to a web-page (or application). One of these is the use of a Gherkin file, which describes the tested feature. This is more compact, and is especially useful for expressions that do not start with the current DOM element. Anyway, there are times when you may want to force integers (perhaps for cosmetic reasons) and you can easily do so using the double-tilde short-cut: ~~. But you can easily achieve any complex logic by using the JS API. This is super-useful when you need to wait for say a table of slow-loading results, and where the table may contain fewer elements at first. There can be multiple Scenario-s in a *.feature file, and at least one should be present. And thats all there is to Karate configuration ! Karate has great options for re-usability, so once the above JSON is saved as locators.json, you can do this in a common.feature: This looks deceptively simple, but what happens is very interesting. { Also note that ; charset=UTF-8 would be appended to the Content-Type header that Karate sends by default, and in some rare cases, you may need to suppress this behavior completely. You need to use karate.toJava() to wrap JS functions passed to custom Java code. If you use commas (instead of concatenating strings using +), Karate will pretty-print variables, which is what you typically want when dealing with JSON or XML. Keep in mind that the reason this exists is to cache data, and not behavior. function(arg) { Note the extra convenience where you dont have to enclose the LHS key in quotes. 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. For e.g. 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. For example, here below is an actual report generated by the cucumber-reporting open-source library. Instead of using call (or callonce) you are always free to call JavaScript functions normally and then you can use more than one argument. You can run tests with this directly, but teams can choose the JUnit variant (shown below) that pulls in JUnit 5 and slightly improves the in-IDE experience. Also see the singular form script(). * 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, """ EndPoint: https://www.kloia.com/ blog?page=2, Given url https://www.kloia.com/ And then you have two options. Take a look at how the configure headers example uses the authToken variable. Karate Framework for web automation. }] If you are new to programming or test-automation, refer to the options for IDE support and the official IntelliJ plugin is recommended. HTML form fields would be URL-encoded when the HTTP request is submitted (by the method step). Note that the optional(), exists() and locate() APIs are a little different from the other Element actions, because they will not honor any intent to retry() and immediately check the HTML for the given locator. If parsing fails, Karate will log a warning and the value of response will then be a plain string. or anything wrapped in parentheses which will be evaluated as JavaScript - e.g. Read the documentation of the stand-alone JAR for more - such as how you can even install custom command-line applications using jbang ! If you find yourself juggling multiple tags with logical AND and OR complexity, refer to this Stack Overflow answer. 1234 to customize rebase filename and/or output), Function to be called when displaying image comparison configuration in Karate HTML reports (e.g. 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. So you can do things like this: * def name = name + __loop - or you can use the loop index value for looking up other values that may be in scope - in a data-driven style. You can find more examples here: xml.feature. note the wildcard '*' in the JsonPath (returns an array), # when inspecting a json array, 'contains' just checks if the expected items exist, # and the size and order of the actual array does not matter, # the .. operator is great because it matches nodes at any depth in the JSON "tree". 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). But you can choose a single test to run like this: When your Java test runner is linked to multiple feature files, which will be the case when you use the recommended parallel runner, you can narrow down your scope to a single feature, scenario or directory via the command-line, useful in dev-mode. The set of built-in functions that start with wait handle all the cases you would need to typically worry about. When the level is DEBUG the entire request and response payloads are logged. 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. A good example of the use of form field for a typical sign-in flow is this OAuth 2 demo: oauth2.feature. Allowed keystore types are as described in the. *.js, *.json, *.txt) as well and it is much more convenient to see the *.java and *.feature files and all related artifacts in the same place. 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. The key should not be within quotes. 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. For a proxy that requires authentication, set the, The charset that will be sent in the request, HTTP requests and responses (including headers) will appear in the HTML report, default. And a very common need would be to use a file as the request body: The rarely used file: prefix is also supported. Keep in mind that the start-up configuration routine could have already initialized some variables before the script even started. deleted: false Karate will scan the log for any string that starts with ws:// and kick things off from there. GET Example 2: In the Given section we are using path/query parameter. In May 2020 it moved up to trial. 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? ] Just write tests in a simple, readable syntax - carefully designed for HTTP, JSON, GraphQL and XML. Of course this can be useful if the element you are seeking is diagonally offset from the locator you have. 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 read from a file, the advantage is that multiple scripts can re-use the same data. The above example can be re-factored in a very elegant way as follows, using Karates native support for JavaScript: The great thing here is that the innnerText() function can be defined in a common feature which all your scripts can re-use. # and even ignore fields at the same time ! Experience working in an Agile environment with agile methodologies leveraging Jira 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. You could use it for hard-coded absolute paths in dev mode, but is obviously not recommended for CI test-suites. """, # karate's unified data handling means that even 'match' works, # which means that checking if a cookie does NOT exist is a piece of cake, # check if the response status is either of two values, # this may be sufficient to check a range of values. Defining the request is mandatory if you are using an HTTP method that expects a body such as post. Imagine a situation where you want to get only the element where a certain attribute value starts with some text - and then click on it. For example if you want to get only the cells out of a
that contain the text data you can do this: Note that the JS in this case is run by Karate not the browser, so you use the Java String.contains() API not the JavaScript String.includes() one. Karate is flexible, you can easily over-write config variables within the Java or JUnit runner - which is very convenient when in dev-mode or rapid-prototyping. 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. REST-style path parameters. Hot Network Questions The Element API has getters for the following properties: This can be convenient in some cases, for example as an alternative to Friendly Locators. isValidTime(_)' Typically right-clicking on the file in the project browser or even within the editor view would bring up the Run as JUnit Test menu option. See karate.callSingle(). There are two variations. Karate, created by Intuit a few years ago, has matured into a stable tool with unique functionality. As a convenience you can use the Chrome concrete implementation of a Driver directly, designed for common needs such as converting HTML to PDF - or taking a screenshot of a page. A variation where the argument is JSON instead of a URL / address-string, used typically if you are testing a desktop (or mobile) application. Here below is an example jbang script that uses the Karate Java API to do some useful work. For tests that need to wait for slow pages or deal with un-predictable element load-times or state / visibility changes, Karate allows you to temporarily tweak the internal retry settings. If you want to disable the auto-embedding into the HTML report, pass an additional boolean argument as false, e.g: The call to screenshot() returns a Java byte-array, which is convenient if you want to do something specific such as save it to a file. The example below combines this with the advanced features described above. Note that if you need to do a lot of case-insensitive string checks, karate.lowerCase() is what you are looking for. So in dev mode you can easily set this behavior like this. { id: 23, name: 'Bob' }, Soumendra Daas has created a nice example and guide that you can use as a reference here: hello-karate. But normally a match statement is preferred unless you want a really descriptive error message. Some XPath expressions return a list of nodes (instead of a single node). You can select a single Scenario (or Scenario-s or Scenario Outline-s or even specific Examples rows) by appending a tag selector at the end of the feature-file you are calling. The above example does not use shared scope, which means that the variables in the calling (parent) feature are not shared by the called my-signin.feature. Because of how easy it is to set HTTP headers, Karate does not provide any special keywords for things like the Accept header. The first argument to karate.callSingle() is used as the cache key. Note that it uses a string contains match, so you just need to supply a portion of the URL you are expecting. But when you use the visible text-content, for example the text within a
