bok-choy can be used along with Travis CI to test changes remotely.
One way to accomplish this testing is to use the headless version of Chrome or Firefox.
bok-choy does this when the
BOKCHOY_HEADLESS environment is set to “true”.
before_script: - export BOKCHOY_HEADLESS=true
Another option is to use the X Virtual Framebuffer (xvfb) to imitate a display.
Headless versions of Chrome and Firefox are relatively new developments,
so you may want to use xvfb if you encounter a bug with headless browser usage.
To use xvfb, you’ll start it up via a
before_script section in your
.travis.yml file, like this:
before_script: - "export DISPLAY=:99.0" - "sh -e /etc/init.d/xvfb start" - sleep 3 # give xvfb some time to start
bok-choy can be used along with tox to test against multiple Python virtual environments containing different versions of requirements.
An important detail when using tox in a Travis CI environment: tox passes along only a fixed list of environment variables to each tox-created virtual environment.
bok-choy via xvfb in tox, the DISPLAY environment variable is needed but is not automatically passed-in.
The tox.ini file needs to specify the DISPLAY variable like this:
[testenv] passenv = DISPLAY
