Usage of @BeforeGroups/@AfterGroups functions

[Asma Jabir]

Hi TestNG team,

I was under the impression that when groups are used, the test will be run, one group at a time, and the @BeforeGroups will be run before executing the first test of the group and @AfterGroups will be run after the last test of the group before moving on to the next group. But when I tried an example, this doesn't seem to be the case. Groups are not considered when running and tests seemed to be running in the defined order. The @BeforeGroups is executed before the first test of the group is executed and @AfterGroup is run after the last test of the group.

Could you please help me understand the @BeforeGroups/@AfterGroups execution logic?

Example:

@BeforeGroups("g1")
public void doBeforeGroupsG1() {
System.out.println("testClass1: before groups g1");
}

@BeforeGroups("g2")
public void doBeforeGroupsG2() {
System.out.println("testClass1: before groups g2");
}

@Test(groups = {"g1"})
public void test1() {
System.out.println("testClass1: test1->g1");
}

@Test(groups = {"g2"})
public void test2() {
System.out.println("testClass1: test2->g2");
}

@Test(groups = {"g1"})
public void test3() {
System.out.println("testClass1: test3->g1");
}

@Test(groups = {"g2"})
public void test4() {
System.out.println("testClass1: test4->g2");
}

@AfterGroups("g2")
public void doAfterGroupsG2() {
System.out.println("testClass1: after groups g2");
}

@AfterGroups("g1")
public void doAfterGroupsG1() {
System.out.println("testClass1: after groups g1");
}

Expected order of execution:

doBeforeGroupsG1

test1

test3

doAfterGroupsG1

doBeforeGroupsG2

test2

test4

doAfterGroupsG2

Actual order of execution:

doBeforeGroupsG1

test1

doBeforeGroupsG2

test2

test3

doAfterGroupsG1

test4

doAfterGroupsG2

Thanks

according to the testng document, "beforegroup" only define which method should run before the first running "@test" method in that group, if you want to limit the order among groups, how about "dependsOnGroups" and "beforegroups" together?

According to document:

doAfterGroupsG1  is warranted for running after the last method of group 1: test1 and test3  

doBeforeGroupsG2  is warranted for running before group 2: test2 and test4

I think actual result is as expected from testng execution graph. However, your expected result also make sense too.
