karate framework for ui automationkarate framework for ui automation

Karate an Open source framework developed by Karatelabs has made Test Automation simple and unified for both API testing and UI Automation using Gherkins. Example: Get the HTML element attribute value by attribute name. That said, the syntax is very concise, and the convention of every step having to start with either Given, And, When or Then, makes things very readable. 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. Normally in dev mode, you will use your IDE to run a *.feature file directly or via the companion runner JUnit Java class. With the Karate framework, testers without a programming background can perform tests more easily. { In cases where the data-source needs multiple steps, for e.g. The results of the first call are cached, and any future calls will simply return the cached result instead of executing the JavaScript function (or feature) again and again. There is also a karate.mapWithKey() for a common need - which is to convert an array of primitives into an array of objects, which is the form that data driven features expect. 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. 'name is Bob and age is 5', # the single cell can be any valid karate expression, * def generator = function(i){ if (i == 20) return null; return { name, Keywords that set multiple key-value pairs in one step, Managing Headers, SSL, Timeouts and HTTP Proxy, Matching Sub-Sets of JSON Keys and Arrays, mix Karate into Java projects or legacy UI-automation suites, Karate entered the ThoughtWorks Tech Radar, 7 New Features in Karate Test Automation Version 1.0, nested chunks of JSON that name-space your config variables, alternate way of calling JavaScript functions, exact same example implemented in REST-assured and TestNG, do not use this unless you know what you are doing, see above, Comparison engine(s) to use. { The following table summarizes some key differences between Cucumber and Karate. For an example of how JavaScript looks like on the Karate side see Function Composition. The default is 30000 (30 seconds). For example: As seen above, you dont have to force all your steps to use the Given, When, Then BDD convention, and you can just use * instead. 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. Path is a keyword in karate. The scenario expression result is expected to be an array of JSON objects. So when you use the combination of callonce in a Background, you can indeed get the same effect as using a @BeforeClass annotation, and you can find examples in the karate-demo, such as this one: callonce.feature. 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. This turns out to be very useful in practice, and this particular match jsonArray contains '#(^partialObject)' form has no in-line equivalent (see the third-from-last row above). Bloating your configuration can lead to loss of performance, and maintainability may suffer. lastUpdated: { on: "#ignore" }, You can even use a regular-expression so that instead of checking for equality, Karate will just validate that the actual value conforms to the expected pattern. We suggest that you have a folder hierarchy only one or two levels deep - where the folder names clearly identify which resource, entity or API is the web-service under test. b In addition to fields, boxes are directly supported like this, so internally a find('select') is chained automatically: One reason why you would need near() is because an field may either be on the right or below the label depending on whether the container element had enough width to fit both on the same horizontal line. Step 3: Add steps to run a sample POST API request. { 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. There can be multiple Scenario-s in a *.feature file, and at least one should be present. If you are new to programming or test-automation, refer to the options for IDE support and the official IntelliJ plugin is recommended. You simply roll your own. Just like script(), but will perform the script eval() on all matching elements (not just the first) - and return the results as a JSON array / list. Step 2: Add Cucumber plugin in Eclipse > Restart eclipse. _ >= 0', _ > 0' }, # when validation logic is an 'equality' check, an embedded expression works better, Then match temperature contains { fahrenheit, # when the response is binary (byte-array), # incidentally, match and assert behave exactly the same way for strings, # if b can be present (optional) but should always be null, """ "c": 3 If you have to set a bunch of deeply nested keys, you can move the parent path to the top, next to the set keyword and save a lot of typing ! } if an API needs to be called to get a JSON array, you can call a separate Scenario to set up this data. Since these are tests and not production Java code, you dont need to be bound by the com.mycompany.foo.bar convention and the un-necessary explosion of sub-folders that ensues. } You can do this. driver.getTitle() becomes driver.title. Here is how to replace one placeholder at a time: Karate makes it really easy to substitute multiple placeholders in a single, readable step as follows: Note how strings have to be enclosed in quotes. Note that Map translates to JSON, and JavaBean getters and setters translate to JS properties - e.g. The syntax is easy to understand by non-programmers. Custom header manipulation for every HTTP request is something that Karate makes very easy and pluggable. Karate Labs is an industry leading open-source test automation solution unifying API & UI test automation. return a pretty-printed, nicely indented string representation of the JSON value, also see: return a pretty-printed, nicely indented string representation of the XML value, also see: get the value of any Java system-property by name, useful for, returns a JSON array of integers (inclusive), the optional third argument must be a positive integer and defaults to 1, and if start < end the order of values is reversed, very rarely used - when needing to perform conditional removal of JSON keys or XML nodes. function() { String interpolation will support variables in scope and / or the Examples (including functions defined globally, but not functions defined in the background). As a rule of thumb, prefer match over assert, because match failure messages are more detailed and descriptive. This will create a folder called myproject (or whatever you set the name to). This is rarely used, unless you are expecting binary content returned by the server. But we recommend that you do this only if you are sure that these routines are needed in almost all *.feature files. Karates approach frees you from Maven, is far more expressive, allows you to eyeball all environments in one place, and is still a plain-text file. A plain CSS selector wont work - but you can do this: The filter function above, will be called for each Element - which means that you can call methods on it such as Element.attribute(name) in this case. 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. For convenience, some stats are logged to the console when execution completes, which should look something like this: The parallel runner will always run Feature-s in parallel. See this other example for more ideas: dsl.feature. For example: While the tag does not need to be in the @key=value form, it is recommended for readability when you start getting into the business of giving meaningful names to your Scenario-s. Karate supports JUnit 5 and the advantage is that you can have multiple methods in a test-class. For example, see the sayHelloFactory() method below: And now, to get a reference to that function you can do this: This can be convenient when using shared scope because you can just call sayHello('myname') where needed. Dont forget that Karates data-driven testing capabilities can loop over arrays of JSON objects automatically. Also refer to the wiki for using Karate with Gradle. Although it is just a few lines of code, take time to study the above example carefully. The wildcard locators are great when the human-facing visible text is within the HTML element that you want to interact with. You can optionally pass in variable values or over-ride config via a HashMap or leave the second-last argument as null. What is Robot Class in Selenium and How to Use it? If you dont pass a handler (or it is null), the first message is returned. They seamlessly fit in-line within your test script. In the example below, note the use of the karate.get() helper for getting the value of a dynamic variable (which was not set at the time this JS function was declared). JavaScript functions have some limitations when combined with multi-threaded Java code. Karate UI automation, is it possible to make locators dynamic. A JavaScript function or Karate expression at runtime has access to a utility object in a variable named: karate. deleted: false A Karate test script has the file extension .feature which is the standard followed by Cucumber. Multi-values are supported the way you would expect (e.g. And thats all there is to Karate configuration ! """, """ This capability is triggered when the table consists of a single cell, i.e. You can even retrieve operating-system environment variables via Java interop as follows: var systemPath = java.lang.System.getenv('PATH'); This decision to use JavaScript for config is influenced by years of experience with the set-up of complicated test-suites and fighting with Maven profiles, Maven resource-filtering and the XML-soup that somehow gets summoned by the Maven AntRun plugin. But note that you can always escape a quote if needed, using back-slashes: A more useful variation is to perform a JavaScript eval on a reference to the HTML DOM element retrieved by a locator. By default, the file is expected to be in the same folder (package) and side-by-side with the *.feature file. input: { Note that the parallel runner will run Scenario-s in parallel, which means they can run in any order.
