#Testng annotations execution flow code

- the annoted method will run before each test method.

- this method will run after the last test method.

- this will run before the first test method executes.

- will run after the annoted test method runs.

- the annoted method will run before the test method.

- this annoted method will run only once after the current class with test method finishes execution.

Below are different Annotations present in TestNG and their primary usage: BeforeSuite: The annotated method will run before all tests in this suite have run.

- this annoted method will run only once before the firsr test method in the current class is invoked. Although Annotations differ from project to project depending on their requirements, the execution flow remains intact for every single project.

- the annoted method will run only once after the execution of tests in the suite.

- the annoted method will run before running the test suites.

If we declare a set of “before” annotations here, they will be the ones to be executed first followed by 'test' annotation methods and then the 'after' annotations. The annotation will execute first, then the and finally the annotation.

#Testng annotations execution flow code

In the above example we have used a very simple strategy to show the flow of execution of the code on the basis of annotations. ('will execute after every static void main() This can be explained with the help of the following code static void main() Annotation Support -Annotations simply means a label that specifies a task to be performed prior execution of rest of the code.NG stands for next generation.įew noticeable features of this framework are : Similar to Junit and Nunit frameworks, it covers a wide range of tests - unit, functional, end-to-end, integration etc. Test classes no longer need to extend anything (such as TestCase, for JUnit 3).It is a framework developed with advanced features in it. We can pass additional parameters to annotations.Īnnotations are strongly typed, so the compiler will flag any mistakes right away. Hence, method names are not restricted to any pattern or format. TestNG identifies the methods it is interested in, by looking up annotations.

The method must return Object[ listeners on a test how to pass parameters to a a class or a method as a part of the test.įollowing are some of the benefits of using annotations − The method that wants to receive data from this DataProvider needs to use a dataProvider name equals to the name of this a method as a factory that returns objects that will be used by TestNG as Test classes. The annotated method must return an Object, where each Object can be assigned the parameter list of the test method. This method is guaranteed to run shortly after the last test method that belongs to any of these groups is annotated method will be run before each test annotated method will be run after each test a method as supplying data for a test method. This method is guaranteed to run shortly before the first test method that belongs to any of these groups is list of groups that this configuration method will run after. Here is the list of annotations that TestNG supports − Sr.No.Īnnotation & annotated method will be run only once before all tests in this suite have annotated method will be run only once after all tests in this suite have annotated method will be run only once before the first test method in the current class is annotated method will be run only once after all the test methods in the current class have annotated method will be run before any test method belonging to the classes inside the tag is annotated method will be run after all the test methods belonging to the classes inside the tag have list of groups that this configuration method will run before. This is a very effective method for tagging certain methods in a class as having a special meaning, but the naming doesn’t scale very well (what if we want to add more tags for different frameworks?) and is rather inflexible (what if we want to pass additional parameters to the testing framework?).Īnnotations were formally added to the Java language in JDK 5, and TestNG made the choice to use annotations to annotate test classes. The traditional way to indicate test methods in JUnit 3 is by prefixing their names with test.
