For inputs like array or dictionary literals, we want to implement something here in a future update. In the general case, it's not possible (because source location information is only available for elements in collection literals.)
Separately, we did just add #_sourceLocation
, although it's not in Xcode or in a tagged release yet.
I updated the title to scope the request a bit more narrowly to something we can actually achieve:
Capture source location of elements in collection literal test arguments
Tracked internally as rdar://130959475
I think we have an earlier radar?
Description
For parameterized tests, I'd like the error report to point to the source line of the failing test case (perhaps as well as the #expect that failed). This makes more sense for sequences of test cases than combinatorial tests.
In XCTest, I used a struct wrapping each test case that captured #file and #line, so I could pass those through to the assertions. (Sub-issue: there's no corresponding #sourceLocation macro so I can't capture the exact location.)
Wrapping each line was annoying. It would really be nice if there were an implicit way to get this information - e.g., automatically capture the source location for each test case, and add an argument or implicit value that you could pass to #expect.
