(used in checking +# partial-match reporting) +# There is also "doing" which sets up title and major test number for each +# block of tests. + +# The first 3 arguments are constant: a minor number (which often gets +# a letter or two suffixed to it internally), some flags, and the RE +# itself. For expectError, the remaining argument is the name of the +# compile error expected, less the leading "REG_". For the rest, the +# next argument is the string to try the match against. Remaining +# arguments are the substring expected to be matched, and any +# substrings expected to be matched by subexpressions. (For +# expectNomatch, these arguments are optional, and if present are +# ignored except that they indicate how many subexpressions should be +# present in the RE.) It is an error for the number of subexpression +# arguments to be wrong. Cases involving nonparticipating +# subexpressions, checking where empty substrings are located, +# etc. should be done using expectIndices and expectPartial. + +# The flag characters are complex and a bit eclectic. Generally speaking, +# lowercase letters are compile options, uppercase are expected re_info +# bits, and nonalphabetics are match options, controls for how the test is +# run, or testing options. The one small surprise is that AREs are the +# default, and you must explicitly request lesser flavors of RE. The flags +# are as follows.
