Travis.yml failing with minimalistic contents?

Question

I have the current travis.yml on my Github:

# see http://about.travis-ci.org/docs/user/languages/php/ for more hints
language: php

# list any PHP version you want to test against
php:
  # aliased to a recent 5.4.x version
  - 5.4
  # aliased to a recent 5.5.x version
  - 5.5

All my jobs keep failing, but with a minimalistic build, i Cannot see why it fails.. As Travis doesn't exactly have the best information.. Here is the last few chunks of my logs:

Job 9.1:

$ git clone --depth=50 --branch=master git://github.com/SlayerSolutions/Authentication.git SlayerSolutions/Authentication

$ phpunit

phpunit [switches] <directory>

 ...Bla,bla,bla

The command "phpunit" exited with 2.

Done. Your build exited with 1.

and Job 9.2:

Is the same and ends with:

The command "phpunit" exited with 2.

Done. Your build exited with 1.

So, what is going wrong here?

Answer 1

Any non-zero exit code of the scripts you run with Travis are considered a failure. Your minimalistic .travis.yml does not specify a build script, therefore the default build script for PHP is run, which is phpunit (see also the documentation).

As you don't have a phpunit.xml in your repository, there is basically nothing to run for Travis. This leads to the failing build.

It really depends what you want to do with Travis, but either you configure your repository according to the default or define a script to execute when running the build like this:

language: php

php:
  - 5.4
  - 5.5

script: ./build.sh

Then you can specify whatever you want in the build.sh to be executed when running build.

You may need to insure that ./build.sh is executable which you can do with

before_install:
  - chmod +x build.sh

You can also make the script bash build.sh or sh build.sh.
