How to do setup and tearDown for a group of tests.

TestNG supports sorting of tests into groups. I can be convenient to be able to perform a group wide setup, before, and teardown, after, the tests in a group are run. This can be accomplished in testNG using the BeforeGroups annotation.

• Sort your tests into logical groups.
• Write test-helper class(es) containing the setup and teardown for the test group(s).
  • It is recommended to write one test-helper for each test group, but if two groups, or more, share exactly the same setup and teardown logic the test-helper can be used by all groups.
  • As of writing, both the groups and value parameters must be set to make this configuration work. This is not what you would expected after reading the testNG documentation of BeforeGroups.

A test-helper class.

class MyDatabaseTestHelper {

  @BeforeGroups(groups = { "database"}, value = { "database"})
  public void setup() {
    //some setup logic
  }

  @AfterGroups(groups = { "database"}, value = { "database"})
  public void tearDown() {
    //some tearDown logic
  }
}
