Learn how to use “Priority” parameter with @Test annotation to execute test cases in a sorted order. With “preserve-order” attribute set to false in in testng.xml file, you can make sure that test cases are executed in an alphabetically sorted order.
Learn how to use dependency testing in TestNG with dependOnMethods or dependsOnGroups annotations to make sure a particular method is run only if all the other dependent methods/groups have been successfully executed. If not, the method/group is skipped.
By grouping tests in TestNG, you can separate different sections or features of a project you are working on. Tests can belong to a single or multiple groups. And again, you can have a group of different groups called MetaGroups.
Learn how to use @DataProvider annotation for executing data driven testing in TestNG. With @DataProvider, testers can automatically run a test case multiple times, with different input and validation values. A good example of this is, suppose, you have to test thousands of forms using automation.
@Parameters annotation is used to pass different values to a method at runtime in TestNG. This allows us to run a test case multiple times with different values from testng.xml file. Let’s take a look at the code example to see how this works.
Annotations in TestNG makes code easier to read, understand, and they also allow test cases to be grouped for efficiency. In this post we’ll cover all the annotations available in the framework and also see code examples to understand their execution flow
