I mentioned a couple of days ago that I had written some testcases down
on a tablet. I'll include them here (as a brain-dump, for now). My
mind does not really think up testcases in any structured sort of way,
so this list is likely not to cover all the cases. Some of the cases
might also be harsher than our expectations. Usually I better organize
the testcases once I start testing, so for now, this is just a
brain-dump:
VARY THE VALUES OF "B" (BEFORE) AND "A" (AFTER) A SINGLE-LINE MATCH:
A=B=0
A=B=1
A=B=4 # (as many lines as won't flush the print buffer, assuming
brint buffer is 10 lines)
A=B=5 # (as many lines as will flush the print buffer
# (even if there is no match, again, assume 10 lines)
A=1, B > A
B=1, A > B
A>numLinesInFile (and expermental variations: ==, A-1, etc.)
B>numLinesInFile (and expermental variations: ==, A-1, etc.)
SINGLE-LINE MATCH NEAR TOP OF FILE PATTERNS:
match only first line of file with B+A+1 lines (try with B=0,1,>1)
match only second line of file with B+A+1 lines (try with B=0,1,>1)
match only third line of file with B+A+1 lines (try with B=0,1,>1)
SINGLE-LINE MATCH NEAR BOTTOM OF FILE PATTERNS:
match only last line of file with B+A+1 lines (try with
B=n,n-1,<n-1)
match only second-to-last line of file with B+A+1 lines (try with
B=n,n-1,<n-1)
match only third-to-last line of file with B+A+1 lines (try with
B=n,n-1,<n-1)
BASIC MULTIPLE-LINE MATCH/NO-MATCH PATTERNS:
line
line
line
line
match
line
match
match
match
line
match
match
match
line
VARIOUS REPEATS OF ABOVE PATTERNS
MORE CONVOLUTED VALUES OF A AND B:
B=0, vary A (A=1,8,9, and 10 with and with single and double line
matches)
A=0, varb B as above
SPECIAL MATCH CASES
empty line
empy consecutive lines
empty non-consecutive lines
empty first line
empty last line
REPEATS OF MULTIPLE FILES CONTAINING ABOVE
LENGTH OF FILE CASES
1 line, not terminated with newline (both match and not-matched
variations)
repeat above but with newline terminated line
0 length file (both as a file and as STDIN)
FILE SOURCE:
STDIN (assume piped STDIN, <, and << all are equvalent) TBD:
determine if assumption valid
file
COMBINED 2 FILES PLUS STDIN (in each order)
MORE CONVOLUTED STUFF:
FF's (and/or other white space) in file
unicode or other alternate forms of line separators
DOS files on UNIX
UNIX files on DOS
Apple variations, combinations with above two
