Commit 0d3ce2ac3f21f7b1af02c64a6c2ba0e9e59eea29
2020-06-02T10:23:41
offer exact name matching with a `$` suffix When using `-s` to specify a particular test, it will do a prefix match. Thus, `-sapply::both::rename_a_to_b_to_c` will match both a test named `test_apply_both__rename_a_to_b_to_c` and a test that begins with that name, like `test_apply_both__rename_a_to_b_to_c_exact`. Permit a trailing `$` to `-s` syntax. This allows a user to specify `-sapply::both::rename_a_to_b_to_c$` to match _only_ the `test_apply_both__rename_a_to_b_to_c` function. We already filter to ensure that the given prefix matches the current test name. Also ensure that the length of the test name matches the length of the filter, sans trailing `$`.
