| -t, --trace Print each line to sys.stdout before it is executed. |
| -c, --count Count the number of times each line is executed |
| and write the counts to <module>.cover for each |
| 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. |
| |
| Filters, may be repeated multiple times: |
| --ignore-module=<mod> Ignore the given module(s) and its submodules |
| (if it is a package). Accepts comma separated |
| list of module names |
| --ignore-dir=<dir> Ignore files in the given directory (multiple |
| directories can be joined by os.pathsep). |
