Developing and Testing

.. todo::
    link to sliderepl or ipython notebook slides

Our tests are inside tests/. Tests are implemented using pytest.

make test will create a tmux server on a separate socket_name using $ tmux -L test_case.

Install the latest code from git

To begin developing, check out the code from github:

$ git clone [email protected]:tony/tmuxp.git
$ cd tmuxp

Now create a virtualenv, if you don't know how to, you can create a virtualenv with:

$ virtualenv .venv

Then activate it to your current tty / terminal session with:

$ source .venv/bin/activate

Good! Now let's run this:

$ pip install -e .

This has pip, a python package manager install the python package in the current directory. -e means --editable, which means you can adjust the code and the installed software will reflect the changes.

$ tmuxp

Test Runner

As you seen above, the tmuxp command will now be available to you, since you are in the virtual environment, your PATH environment was updated to include a special version of python inside your .venv folder with its own packages.

$ make test

You probably didn't see anything but tests scroll by.

If you found a problem or are trying to write a test, you can file an issue on github.

Test runner options

Test only a file:

$ py.test tests/test_config.py

will test the tests/test_config.py tests.

$ py.test tests/test_config.py::test_export_json

tests test_export_json inside of tests/test_config.py.

Multiple can be separated by spaces:

$ py.test tests/test_{window,pane}.py tests/test_config.py::test_export_json

Visual testing

You can watch tmux testsuite build sessions visually by keeping a client open in a separate terminal.

Create two terminals:

• Terminal 1: $ tmux -L test_case

• Terminal 2: $ cd into the tmuxp project and into the virtualenv if you are using one, see details on installing the dev version of tmuxp above. Then:

  $ py.test tests/test_workspacebuilder.py

Terminal 1 should have flickered and built the session before your eyes. tmuxp hides this building from normal users.

Run tests on save

You can re-run tests automatically on file edit.

Note

This requires entr(1).

Install entr. Packages are available available on most Linux and BSD variants, including Debian, Ubuntu, FreeBSD, OS X.

To run all tests upon editing any .py file:

$ make watch_test

You can also re-run a specific test file or any other py.test usage argument:

$ make watch_test test=tests/test_config.py

$ make watch_test test='-x tests/test_config.py tests/test_util.py'

Rebuild sphinx docs on save

Rebuild the documentation when an .rst file is edited:

$ cd doc
$ make watch

tmuxp developer config

After you :ref:`install_dev_env`, when inside the tmuxp checkout:

$ tmuxp load .

this will load the .tmuxp.yaml in the root of the project.

.. literalinclude:: ../.tmuxp.yaml
    :language: yaml

Travis CI

tmuxp uses travis-ci for continuous integration / automatic unit testing.

tmuxp is tested against tmux 1.8 and the latest git source. Interpretters tested are 2.6, 2.7 and 3.3. The travis build site uses this .travis.yml configuration:

Testing options

RETRY_TIMEOUT_SECONDS can be toggled if certain workspace builder tests are being stubborn.

e.g. ``RETRY_TIMEOUT_SECONDS=10 py.test ``

.. literalinclude:: ../.travis.yml
    :language: yaml
