3 # The tests are in a separate file 't/op/re_tests'.
4 # Each line in that file is a separate test.
5 # There are five columns, separated by tabs.
7 # Column 1 contains the pattern, optionally enclosed in C<''>.
8 # Modifiers can be put after the closing C<'>.
10 # Column 2 contains the string to be matched.
12 # Column 3 contains the expected result:
16 # T the test is a TODO (can be combined with y/n/c)
17 # B test exposes a known bug in Perl, should be skipped
18 # b test exposes a known bug in Perl, should be skipped if noamp
19 # t test exposes a bug with threading, TODO if qr_embed_thr
21 # Columns 4 and 5 are used only if column 3 contains C<y> or C<c>.
23 # Column 4 contains a string, usually C<$&>.
25 # Column 5 contains the expected result of double-quote
26 # interpolating that string after the match, or start of error message.
28 # Column 6, if present, contains a reason why the test is skipped.
29 # This is printed with "skipped", for harness to pick up.
31 # \n in the tests are interpolated, as are variables of the form ${\w+}.
33 # Blanks lines are treated as PASSING tests to keep the line numbers
34 # linked to the test number.
36 # If you want to add a regular expression test that can't be expressed
37 # in this format, don't add it here: put it in op/pat.t instead.
