NUnit and TestCaseAttribute, cross-join of parameters possible?

I have a unit-test that tests a variety of cases, like this:

public void Test1(Int32 a, Int32 b, Int32 c)

Let's say I want to create test-code without a loop, so I want to use TestCase to specify parameters like this:

[TestCase(1, 1, 1)]
public void Test1(Int32 a, Int32 b, Int32 c)

Is it possible for me with this attribute to say this:

• For the first parameter, here's a set of values
• For the second parameter, here's a set of values
• For the third parameter, here's a set of values
• Now, test all combinations of the above

Ie. something like this:

[TestCase(new[] { 1, 2, 3, 4 }, new[] { 1, 2, 3, 4 }, new[] { 1, 2, 3, 4 })]
public void Test1(Int32 a, Int32 b, Int32 c)

Doesn't seem like it开发者_运维问答, but perhaps I'm overlooking something?

NUnit provides the Values attribute which can be used together with Combinatorial attribute to achieve this:

[Test, Combinatorial]
public void Test1( 
    [Values(1,2,3,4)] Int32 a, 
    [Values(1,2,3,4)] Int32 b, 
    [Values(1,2,3,4)] Int32 c
)
{
    ...
}
