Coded UI - Single datasource for multiple testmethods - datasource

Question

So, I have say 3 TestMethods. I attach the same datasource to each, then run with 5 rows of data. I get 5 iterations of TM #1 followed by 5 of TM #2 followed by 5 of TM #3.
11111 22222 33333
What I'd prefer is to have is an iteration of all 3 TMs, followed by another etc.
123 123 123 123 123
I know you're not supposed to have dependencies among test methods, but the fact of the matter is that it's a workflow-driven application, and their are dependencies among operations. Can't do 2 until you've done 1, can't do 3 until you've done 2. Once you've done 1, you can't do it again. etc.
11111, 22222, 33333 works, when all goes well, and is appropriate for some test cases, but doesn't realistically reflect the way the app is used. And when it doesn't work, it can burn up a lot of data that we can't re-use and so end up having to generate new.
Diligently reading help and Googling like a fool has not produced any useful guidance on how... or even whether... this can be done.
Thoughts?

Answer 1

You can try wrapping them in to one test case and add data source to it.
[TestMethod]
[DataSoruce XXXXXXX]
public void OuterTest()
{
Scenario1();
Scenario2();
Scenario3();
}
private void Scenario1()
{
// Do your Stuff
}
private void Scenario2()
{
// Do your stuff
}
private void Scenario3()
{
// Do your stuff
}
then you will have iteration like 123 123 123 123 123
