This section describes the testing framework and options for testing MEGARA DRP

**************
Running tests
**************

MEGARA DRP uses `pytest <http://pytest.org>`_ as its testing framework.
We require also the package `pytest-remotedata` to control access to online
resources during testing.

As MEGARA DRP does not contain C/Cython extensions, the tests can be run
directly in the source code, as::

    cd megaradrp-0.4.0
    pytest megaradrp
    
Some of the tests rely on data downloaded from a server. These tests are
skipped by default. To enable them run instead::

    py.test --remote-data megaradrp

The reduction recipes are tested with remote data. Each recipe is run in
a directory created under the default ``$TMPDIR``, which is based on
the user temporal directory. The base of the created directories can be changed
with the option ``--basetemp=dir``::

    py.test --basetemp=/home/spr/test100 --remote-data megaradrp
