TestNG should provide an Api which allow to find all dependent of a specific test

[juherr]

https://issues.apache.org/jira/browse/SUREFIRE-1073

[krmahadevan]

@juherr - What is the expectations of this issue. I would specifically like to know the following:

1. How will the user invoke this? Should this be made available only when someone creates a TestNG instance ?
2. What would the input for this api look like ?

It would be good if you could please help add some additional context into this issue.

[juherr]

It is for the integrations. The need is to add the dependent TestMethods on TestMethod api

[krmahadevan]

You mean something like public List<ITestNGMethod> getDownstreamDependencies() into ITestNGMethod interface right ?

[juherr]

Yes, exactly. It exists in the model but not available by the api.

About the naming, I think something closer the annotation attribute name will be better.

About the naming, I think something closer the annotation attribute name will be better.

What attribute are you referring to here? In TestNG, we only have a mapping from a child (Dependent method) to a parent (Independent method upon which the dependent method depends on)

But here we are asking for all children, given a parent.

public class TestClassSample {

  @Test
  public void independent() {}

  @Test(dependsOnMethods = "independent")
  public void dependent() {}

  @Test(dependsOnMethods = "independent")
  public void anotherDependent() {}
}

Here we are asking for an API, wherein if we give input as independent() it should return dependent() and anotherDependent(). Is this the right expectations?

If yes, then I think the api should be called as getDownstreamDependencies(). WDYT ?

For upstream dependencies ( which is what dependsOnMethods represents) we have this String[] getMethodsDependedUpon(); in the ITestNGMethod interface.

[juherr]

I will check again. I thought the need was to have getMethodsDependedUpon() returning object instead of string

@juherr - I have raised a PR which now provides both upstream and downstream dependencies for a test method. Please check.
