Can Travis-CI run Codeception tests? - testing

Question

I'm creating my tests (though I'm a beginner, learning) using Codeception. This includes acceptance and unit tests for now.
I want to add my repo to Travis CI so I can automate testing process after each commit and put build-status tag.
I would like to ask;
Can Travis-CI run codeception tests?
Can Travis-CI run codeception acceptance tests emulating browser?
If both answers are no, is there any other CI tool which can?
Thank you.

Yes, it is possible to run Codeception tests, including acceptance tests that run using WebDriver, on Travis CI.
It is possible to run your tests with a real browser on Travis, but it is easiest to use a headless browser, since Travis is running on a headless machine. PhantomJS is perfect for this, and it comes pre-installed with Travis CI's build bootstrap.
To run the tests with PhantomJS, you'll need to configure the WebDriver module like this in your .yml Codeception configuration file:
modules:
config:
WPWebDriver:
url: 'http://127.0.0.1:8888'
browser: phantomjs
The URL is important. I have found that attempting to use localhost instead of 127.0.0.1 will not work. Also, if you accidentally leave out the http://, that won't work either. You can use most any 8*** port, since most of them are open, but of course you'll need to have a web server running on that port to serve your static files or run your PHP application. The easiest way to do this, I find, is to use PHP's built-in webserver.
Your .travis.yml file might look something like this:
# Travis CI configuration file.
language: php
php:
- 5.6
- 7.0
before_script:
# Start up a web server.
- php -S 127.0.0.1:8888 -t /path/to/web/root >/dev/null 2>&1 &
# Start up the webdriver.
- phantomjs --webdriver=4444 >/dev/null 2>&1 &
# Install Codeception.
# Doing this last gives the webdriver and server time to start up.
- composer install --prefer-source
script:
- vendor/bin/codecept run
You will of course need to add Codeception to your project's composer.json file:
composer require --dev codeception/codeception
You'll also need to change path/to/web/root above to the path to the directory where you want the server's document root to be.
If you'd like to see a working demo running WebDriver tests against WordPress, you can check out this GitHub repo.

I'd think that it can be done, but gluing everything tohether is not going to be for the faint of heart. Reason why I think it can be done is that codeception, itself, is ci-ed on Travis. See https://travis-ci.org/Codeception/Codeception. I'd contact the people at codeception and ask for their thoughts.
Or you can take a peek at how they do it in the build logs, such as:
https://travis-ci.org/Codeception/Codeception/jobs/14432638
Looks like they're running headless with a downloaded standalone selenium server.
Travis-ci have some information on how to run GUI tests. In particular, they allow you to use a sauce labs account and run distributed selenium tests from there.

I ran into this problem today and I solved it by adding Codeception to my composer.json:
"require-dev": {
"codeception/codeception": "^2.1"
},
and referring to it on my .travis.yml:
install:
- composer self-update
- composer install
before_script:
- #Code that creates and seeds my database and so on
script: php vendor/codeception/codeception/codecept run
