#TESTNG ANNOTATIONS HIERARCHY WITH EXAMPLE IN XML FILE CODE#

No Need To Extend Any Class - While using the annotations, there is no need to extend any Test class like JUnit.Strongly Typed- Annotations type strongly, and the errors can be encountered during the run time, which saves time for the testers.Can Be Parameterized - Annotations can also be parameterized, just like any other method in Java.There is no predefined rule or format, and the tester just needs to annotate methods using their judgment. Easy To Learn - The annotations are very easy to learn and execute.TestNG annotations boast the following benefits: If TestNG draws so much from its annotations, there must be a few benefits associated with it. It is one of the primary reasons to prefer TestNG as it is simple and easy to learn. These annotations have self-explanatory meanings. - The method in TestNG run after the test cases of that group execute.- The method in TestNG run before the test cases of that group execute.- The method in TestNG will run after each test method is executed.- The method in TestNG will execute before each test method.- The method in TestNG will execute after all the test methods of the current class execute.- The method in TestNG will run before the first method invokes of the current class.- The method in TestNG executes after the execution of all the test methods that are inside that folder.- The method in TestNG runs before the execution of all the test methods that are inside that folder.- The method in TestNG runs after the execution of all other test methods.- The method in TestNG runs before the execution of all other test methods.In TestNG, there are ten types of annotations: In the section, you will find their definition along with their meaning. There are many types of annotations in TestNG.

Apart from the ' symbol and the header file ( of course), there is nothing you require to run TestNG annotations. These names are predefined, and we will discuss them in the later section of this tutorial. TestNG will ignore the method which does not contain an annotation since it won't know when to execute this method.Ī TestNG annotation starts from the symbol ' and whatever follows is the annotation name. It is essential to annotate your methods in TestNG to run the tests.

TestNG annotations are the code that is written inside your source test code logic to control the flow of the execution of tests. TestNG also uses them for the same reason. This tutorial includes the TestNG Annotations with the following content:Īnnotations, in general, mean ' a comment' or ' a note' on a diagram, etc. Annotations are taken from the Java language and are an excellent tool for the testers using TestNG. Tests annotate to decide the sequence of the tests that run. If priority is not specified, then the default priority will be 0.In the introduction to the TestNG tutorial, we highlighted TestNG briefly and focussed on how TestNG fetches its power from its annotations. Suppose we have three test cases and their priority values are -5000, 0, 15, then the order of the execution will be 0,15,5000. When the priority is set, the lowest priority test case will run first and the highest priority test case will be executed last. The priority can hold the integer values between -50. Priority determines the sequence of the execution of the test cases. When no 'priority' attribute is specified then the TestNG will run the test cases in alphabetical order. In the above code, testcase1() is dependent on two methods, i.e., testcase2() and testcase3(), which means that these two methods will be executed before the testcase1(). Second case: When multiple values are passed in a parameter. In the above output, MobileStudentLogin() runs before the WebStudentLogin() method as TestNG runs the test methods in an alphabetical order. In the above program, we have specified 'dependsOnMethods' attribute in an APIStudentLogin() test method and its value is 'WebStudentLogin' which means that WebStudentLogin() method will be executed before the APIStudentLogin() method. However, we want WebStudentLogin() method to be executed before the execution of the APIStudentLogin() method, so this would only be possible through the 'dependsOnMethods' attribute. We know that the TestNG executes the test methods in alphabetical order so, in the above program, APIStudentLogin() will execute first. ('Student login through void MobileStudentLogin()
