Hi,

You should be aware that Theories are somewhat experimental and underdeveloped
right now with significant changes planned for 3.0. The basic idea of
theories is that
the developer does _not_ control what test cases will be generated.

In the current NUnit implementation, I allowed use of the standard
data parameters
to supplement any data generated by NUnit, thereby guaranteeing that some
particular test cases will be used. Such test cases will probably be treated
differently in the future.

I'm moving this feature request to the 3.0 project so it can serve as a reminder
of the issues you are raising there.

Status in NUnit Test Framework: New

Bug description:
We should avoid usinge the mechanism for parameterized test in theories. The following example has "exploding" combinatorical parameters. To avoid this, we must use ValueSource.

  [Datapoints]
  public double[] as = new double[] { 0.0, 1.0, -1.0, 42.0 };
  public double[] bs = new double[] { 0.0, 1.0, 100.0 };

  [Theory]
  public void Add(double num1, double num2)
  {
    Assert.That(num1 + num2 == num2 + num1);
  }


But it might be nicer if we really can avoid it using a new attribut Use:
  [Theory]
  public void Add([Use(as)] double num1, [Use(bs)] double num2)
  {
    Assert.That(num1 + num2 == num2 + num1);
  }
