PHPunit no tests execute on Travis CI - php

Question

I'm been following a PHPUnit tutorial for the first time and my tests run fine locally. However, when running my tests on Travis CI, no tests are executed and my build exits with 0.
My directory structure and full code can be seen on the repo.
Build log from Travis CI (Full build log)

Done. Your build exited with 0.

.travis.yml:
language: php
php:

- 5.5
before_script:
- curl -s http://getcomposer.org/installer | php
- php composer.phar install
script: vendor/bin/phpunit --debug
My tests run successfully locally, however maybe there is an issue somewhere with my phpunit.xml file?

Answer 1

The directory containing your tests is incorrect.
The correct path would be phpUnitTutorial/tests. Note that Windows does not care about case sensitivity, but everyone else in the world does. Best thing would be to always use lower case for paths, or double check you are using the correct case everywhere (PSR-0 and PSR-4 would require path names with the same case as the class name, which will usually include upper case letters).
And by the way: You should probably upgrade to a more recent version of PHPUnit. That old 3.7 series is not getting any more updates for years now, and the transition to 4.x isn't too steep - you should just do it.

Answer 2

language: php
php:
- 5.4
- 5.5
install: composer install
script: ./vendor/bin/phpunit
Not sure about install: composer install, probably can be omitted
