How to have just one pre-requisite check in TestNG for multiple tests distributed across classes

Question

I have a Test Automation project using TestNg.

I want to make sure certain configurations are enabled before I start some of the tests. I have written this as a test and marked other tests as dependent on this. So I have used the TestNG param "dependsOnMethods" for all the individual tests which are dependent on this check.

These tests are distributed across multiple classes and I currently have to do this check in each and every class, which works fine if all tests are passing, but if there is a configuration missing, I get a bunch of errors because the test which is doing this check fails and then I have a copy of this failure in almost every class I have.

So instead of 1 failure, I end up with 10 failures, as this failure happens multiple times.

This can't be a @BeforeTest or @BeforeMethod or @BeforeClass since this is required for only a few of the tests in a TestClass.

I can set a Global Flag based on the failure of this test, but then again I can't skip Testng tests based on Flags. So I will get false Negatives.

Is there a way to create a test in a parent class and skip some tests if this fails?

Answer 1

I'm not really sure if TestNG allows to have a common dependsOnMethods for multiple classes.

You can try another option called dependsOnGroups.

Here is an article to help you with it. As I am not aware of the copyrights of the content of the reference article. I am only giving a link rather than copying the content here.

So if one has to skip tests based on a boolean you can use SkipException. This helps when we don't want to depend on a method call using dependsOnMethods param of TestNg

@Test()
public void testDependingOnData {
  if(dataMissing) {
     throw new SkipException("We skip this Test");
  }
  // Test Steps here
}

By using grouping. You can create a group of tasks you want to execute and then make a suite for it and only those test cases will run. 2. By using enable and disable in the test method such that only the test case where enabled = true will execute and the test methods with enabled = false will not.
