Coverage.py API
===============
There are a few different ways to use coverage.py programmatically.
The API to coverage.py is in a module called :mod:`coverage`. Most of the
interface is in the :class:`coverage.Coverage` class. Methods on the Coverage
object correspond roughly to operations available in the command line
interface. For example, a simple use would be::
import coverage
cov = coverage.Coverage()
cov.start()
# .. call your code ..
cov.stop()
cov.save()
cov.html_report()
Any of the methods can raise specialized exceptions described in
:ref:`api_exceptions`.
Coverage.py supports plugins that can change its behavior, to collect
information from non-Python files, or to perform complex configuration. See
:ref:`api_plugin` for details.
If you want to access the data that coverage.py has collected, the
:class:`coverage.CoverageData` class provides an API to read coverage.py data
files.
.. warning::
Only the published documented portions of the API are supported. Other
names you may find in modules or objects can change their behavior at any
time. Please limit yourself to documented methods to avoid problems.
All internal code in coverage.py has docstrings; this does not make them
part of the public supported API. Many internal names have no leading
underscore; this does not make them part of the public supported API. If
classes or functions are not documented in this published documentation,
they are not supported.
For more intensive data use, you might want to access the coverage.py database
file directly. The schema is subject to change, so this is for advanced uses
only. :ref:`dbschema` explains more.
