Could the stack trace of expect_no_*() be reduced?

[olivroy]

if I have the following

test_that("test", {

  expect_no_error(function_that_throws_a_warning())

})

I get the following trace in the build pane on Windows. I am noting that the expect_no_error() traceback takes 11 lines, but it doesn't seem very interesting to know that expect_no_error calls all these functions? Lines 2 to 11 don't feel relevant to me.

Is there a solution for that?

Verify also if the trace from expect_warning(regexp = NA) is smaller?

The mechanisms exist in rlang to trim the call stack; the challenge will be figuring out exactly what should form the top of the callstack and how do we get that information to where the back trace is generated.

I think I'm going to close this, just because when we've tried to automatically minimise the stack we've hit a case where we accidentally hide info that we do actually want.
