On the surface, this makes sense, but after further analysis there are
some issues...
1. When no categories are selected, all tests are run but
SelectedCategories will be empty. This could be handled by the user
checking for an empty list.
2. Categories may also be excluded. We would need to provide a separate list
for these categories and the user would have to test it as well. So the test
would become something like...
If ( TestContext.SelectedCategories.Contains("long") &&
!TestContext.ExcludedCategories.Contains("long) )...
with added logic to handle empty lists, depending on what the user wanted to
accomplish.
3. A category expression may be provided, like A + B - C. This cannot be
expressed as a simple list so the user would be forced to duplicate
NUnit's parsing of the expression. Further, this expression syntax is
likely to change in the next version of NUnit.
I'm open for suggestions on how to deal with these problems, either from
the original proposer or from others.
An alternative is to use the TestCaseSourceAttribute to provide data. We
have recently added a Category property to that attribute, allowing the
example to be rewritten as follows:
IEnumerable shortData = new object[] { item1, item2 };
IEnumerable longData = new object[] { item3, item4, ... , itemN }
[TestCaseSource("longData", Category="long")]
[TestCaseSource("shortData", Category="short")]
Public void SomeTest(List<SomeType> list)
{
ProcessList(List);
}
This seems to me to solve all the problems and eliminate the need for
the requested feature. Thoughts?

Title:
Feature request: Provide interface to query selected categories
Status in NUnit V2 Test Framework:
Triaged
Bug description:
Please implement a feature that will provide a list of which
categories have been chosen for the test run (using the include list).
Here's a code sample of how this could be used in future:
TestContext.SelectedCategories would offer a collection indicating
which categories were selected.
[Test]
[Category("long")]
[Category("short")]
Public void SomeTest()
{
List.Add(item1);
List.Add(item2);
If(TestContext.SelectedCategories.Contains("long"))
{
List.Add(item3);
List.Add(item4);
...
List.Add(itemN);
}
ProcessList(List);
}
Depending on the content of the list, this test might either take an
hour (full scope) or 2 minutes (reduced scope).
