===========A coverage plugin to provide sensible default settings
## installation
```bash
pip install covdefaults
```## usage
to enable the plugin, add `covdefaults` to your coverage plugins
in `.coveragerc`:
```ini
[run]
plugins = covdefaults
```in `setup.cfg` / `tox.ini`:
```ini
[coverage:run]
plugins = covdefaults
```in `pyproject.toml`:
```ini
[tool.coverage.run]
plugins = ["covdefaults"]
```## default settings
### `[coverage:run]`
```ini
branch = True
source = .
omit =
*/__main__.py
*/setup.py
```### `[coverage:report]`
```ini
show_missing = True
skip_covered = True
fail_under = 100
exclude_lines =
# a more strict default pragma
\# pragma: no cover\b# allow defensive code
^\s*raise AssertionError\b
^\s*raise NotImplementedError\b
^\s*return NotImplemented\b
^\s*raise$# typing-related code
^\s*if (False|TYPE_CHECKING):
: \.\.\.(\s*#.*)?$
^ +\.\.\.$
-> ['"]?NoReturn['"]?:# non-runnable code
if __name__ == ['"]__main__['"]:$# additional platform related pragmas (see below)
# additional version related pragmas (see below)
partial_branches =
# a more strict default pragma
\# pragma: no cover\b# our platform pragmas
\# pragma: (nt|posix|cygwin|darwin|linux|msys|win32|cpython|pypy) (no )?cover\b# our version pragmas
\# pragma: (>=?|<=?|==|!=)\d+\.\d+ cover\b
```### platform specific `# pragma: no cover`
several `# pragma: no cover` tags will be added automatically based on the
platform and implementation.these will be in the form of:
```python
# pragma: TAG no cover
```or
```python
# pragma: TAG cover
```these tags will be generated by the following values:
- `os.name`
- `nt` (windows)
- `posix` (linux, macOs, cygwin, etc.)
- `sys.platform`
- `cygwin`
- `darwin` (macOs)
- `linux`
- `msys`
- `win32`
- `sys.implementation.name`
- `cpython`
- `pypy`for every tag which does not match, you can use negation. here's an example:
```python
if sys.platform == 'win32': # pragma: win32 cover
bin_dir = 'Scripts'
else: # pragma: win32 no cover
bin_dir = 'bin'
```note here that `# pragma: win32 cover` will become a "no cover" for everything
which is not `win32` -- whereas the `# pragma: win32 no cover` will be a
"no cover" only on `win32`.### version specific `# pragma: no cover`
several `# pragma: no cover` tags will be added automatically based on the
platform and implementation.these will be in the form of:
```python
# pragma: >=#.# cover
```where the comparison operator is one of `>`, `>=`, `<`, `<=`, `==`, `!=`
for example:
```python
if sys.version_info >= (3, 9): # pragma: >=3.9 cover
print('3.9+')
else: # pragma: <3.9 cover
print('old')
```### overriding options
several of the options can be overridden / extended in your coverage
configuration. the examples below assume `.coveragerc` however any of the
files `coverage` supports work as well.#### `run:omit`
```ini
[run]
omit =
pre_commit/resources/*
```this will result in the `pre_commit/resources/*` being `omit`ted in addition
to the defaults provided by `covdefaults`.```ini
[covdefaults]
subtract_omit = */__main__.py
```this will result in `*/__main__.py` not being `omit`ted (`*/__main__.py` is
among the defaults provided by `covdefaults`).#### `run:source`
```ini
[run]
source = $PWD
```covdefaults will not override this value to `.` if it is set manually.
#### `report:exclude_lines`
```ini
[report]
exclude_lines =
^if MYPY:$
```this will result in lines matching `^if MYPY:$` to additionally be excluded
from coverage in addition to the defaults provided by `covdefaults`.#### `report:fail_under`
```ini
[report]
fail_under = 90
````covdefaults` will not change the value if you provide one for `fail_under`
