Configuration information for a TestNG class:
@BeforeSuite: The annotated method will be run before all tests in this suite have run.
@AfterSuite: The annotated method will be run after all tests in this suite have run.
@BeforeTest: The annotated method will be run before any test method belonging to the classes inside the <test> tag is run.
@AfterTest: The annotated method will be run after all the test methods belonging to the classes inside the <test> tag have run.
@BeforeGroups: The list of groups that this configuration method will run before. This method is guaranteed to run shortly before the first test method that belongs to any of these groups is invoked.
@AfterGroups: The list of groups that this configuration method will run after. This method is guaranteed to run shortly after the last test method that belongs to any of these groups is invoked.
@BeforeClass: The annotated method will be run before the first test method in the current class is invoked.
@AfterClass: The annotated method will be run after all the test methods in the current class have been run.
@BeforeMethod: The annotated method will be run before each test method.
@AfterMethod: The annotated method will be run after each test method.
@AfterSuite: The annotated method will be run after all tests in this suite have run.
@BeforeTest: The annotated method will be run before any test method belonging to the classes inside the <test> tag is run.
@AfterTest: The annotated method will be run after all the test methods belonging to the classes inside the <test> tag have run.
@BeforeGroups: The list of groups that this configuration method will run before. This method is guaranteed to run shortly before the first test method that belongs to any of these groups is invoked.
@AfterGroups: The list of groups that this configuration method will run after. This method is guaranteed to run shortly after the last test method that belongs to any of these groups is invoked.
@BeforeClass: The annotated method will be run before the first test method in the current class is invoked.
@AfterClass: The annotated method will be run after all the test methods in the current class have been run.
@BeforeMethod: The annotated method will be run before each test method.
@AfterMethod: The annotated method will be run after each test method.
For before methods (beforeSuite, beforeTest, beforeTestClass and beforeTestMethod, but not beforeGroups): If set to true, this configuration method will be run regardless of what groups it belongs to.
For after methods (afterSuite, afterClass, …): If set to true, this configuration method will be run even if one or more methods invoked previously failed or was skipped.
For after methods (afterSuite, afterClass, …): If set to true, this configuration method will be run even if one or more methods invoked previously failed or was skipped.
@DataProvider
Marks a method as supplying data for a test method. The annotated method must return an Object[][] where each Object[] can be assigned the parameter list of the test method. The @Test method that wants to receive data from this DataProvider needs to use a dataProvider name equals to the name of this annotation.
Parameters for dataprovider –
a. name
The name of this data provider. If it’s not supplied, the name of this data provider will automatically be set to the name of the method.
b. parallel
If set to true, tests generated using this data provider are run in parallel. Default value is false.
@Factory
Marks a method as a factory that returns objects that will be used by TestNG as Test classes. The method must return Object[].
@Listeners
Defines listeners on a test class.
.
@Parameters
Describes how to pass parameters to a @Test method.
@Test -> AnnotationMarks a class or a method as part of the test.
@Test (name=“example“,
description=“example test“,
expectedExceptions=IOException.class,
dataProvider=“dataProv“,
groups={“functional“,“stress“},
dependsOnGroups=“database“,
dependsOnMethods={“init“,“setup“},
enabled=true,
successPercentage=80,
timeout=10000,
invocationCount=10,
threadPoolSize=10,
sequential=true)
Hope this helps !!!!
