|
| module executed, in the module's directory.
|
| See also `--coverdir', `--file', `--no-report' below.
|
| -l, --listfuncs Keep track of which functions are executed at least
|
| once and write the results to sys.stdout after the
|
| program exits.
|
| -T, --trackcalls Keep track of caller/called pairs and write the
|
| results to sys.stdout after the program exits.
|
| -r, --report Generate a report from a counts file; do not execute
|
| any code. `--file' must specify the results file to
|
| read, which must have been created in a previous run
|
| with `--count --file=FILE'.
|
|
|
| Modifiers:
|
| -f, --file=<file> File to accumulate counts over several runs.
|
| -R, --no-report Do not generate the coverage report files.
|
| Useful if you want to accumulate over several runs.
|
| -C, --coverdir=<dir> Directory where the report files. The coverage
|
| report for <package>.<module> is written to file
|
| <dir>/<package>/<module>.cover.
|
| -m, --missing Annotate executable lines that were not executed
|
| with '>>>>>> '.
|
| -s, --summary Write a brief summary on stdout for each file.
|
| (Can only be used with --count or --report.)
|
| -g, --timing Prefix each line with the time since the program started.
|
| Only used while tracing.

|
| (if it is a package). Accepts comma separated
