Test → Representation of Test which can be one or more in a Suite.Ĭlasses → Also known as TestNG class, contains one or more test methods. Suite → Top level of any TestNG project and is maintained as an XML artifact. Diagram below depicts its architecture at high level.īelow are some terminologies used in above diagram to help us understand more about the architecture. TestNG is designed to cover all categories of tests: unit, functional, end-to-end, integration, etc.īefore moving ahead with TestNG, it is important to understand it's basic architecture. is an open source Java testing framework which is powerful yet easy to use. TestNG Annotation Execution Flow Interview Question: TestNG Annotation Execution Flow Selenium Example Program? package Therefore choosing the right ones for proper use is important. After each execution of the script, it provides us a detailed report so that we can share those reports at the time of status reporting.īut using the above annotations is depends on your business requirement, hence Choose the right ones as per your requirement is important. Also, it has some more rich functionality by using those we can save lots of time. The annotations, as mentioned earlier of TestNG, are to provide a better structure and readability to code. ('shutdown the connection with void openBrowser() ('establishing the connection with void closeConnection() TestNG Annotation With Example package Testing The Sequence order of execution of all the above annotation is like below It helps in tracking the execution status and logging purpose. It defines an array of test listeners classes extending. This is used to run a set of test cases with different This is applied to a test class. These class objects will then be used as test classes by TestNG. The method which wants input data from data provider that needs to use the data provider name, which you mentioned at the time of creating the data Marks an annotated method as a factory that returns an array of class objects (Object). The annotated method must return an object. So we can use annotation to make that method as a data supplier. These parameter values are provided using the testng.xml configuration file at If any of your methods required some input data, then we can pass the data to that method. We can use this tag for print what tests are going to run, browser name and project name, which is common for all the The annotated method will be executed after any tests declared inside a TestNG BeforeGroups annotated method will run before any of the test methods of the specified group is AfterGroups annotated method will run after any of the test methods of the specified group gets This annotation is used to pass parameters to a test method. If a suite contains multiple tests, these annotated methods will not be applicable for all The annotated method will be executed before any tests declared inside a TestNG suite. We are using this type of annotation to set up any specific configuration for the The annotated methods will execute after each tag, which is declared inside a TestNG suite. The annotated methods will be executed before tag is run. Note: and methods are unique to a particular A Suite can have several tests. So annotated methods are executed before the execution of any of the methods of that These annotated methods are executed after the execution of all test methods of a test class are executed. This is one of the important annotations in TestNG because inside that we need to write the business If you declare a test case or method with this annotation, then the annotated method will be executed before the execution of each annotated Those methods are annotated by the method executed after the execution of each annotated A class can have multiple classes, and each class can have various methods in it. If you declare this annotation at class level, then all the methods present inside the class will be considered as a test method. TestNG Annotation With You can use this annotation in class or method level for the test method. us try to understand all the above annotations one by one.
