Travis Jobs

There are two types of configs

• Matrices and
• stages.

Matrices you would use to easily mix and match several settings. You want to test (nearly) all of them. Matrix projects run in parallel.

Using stages you generally want a specific order. Stage projects run sequentially and parallel within a stage (-> aka matrix expansion or via multiple stages having the same name).

Matrix expansion per stage will hopefully integrated soon.

YAML Config Files

• Travis uses YAML 1.1. See here for the full specification
• Is is often useful to have a YAML linter at hand. If find yamllint (pip install yamllint) is a good choice.

Travis CLI

Not on Windows users: I never managed to get that working on Windows (like encrypting a password for deployment). Just use a Linux virtual machine.

Encrypt secret

/home/marcel/.gem/ruby/2.6.0/gems/travis-1.8.9/bin/travis encrypt "<data to encrypt>" -r <GitHub user or organisation>/repo
Please add the following to your .travis.yml file:

  secure: "<some long hash>"

Pro Tip: You can add it automatically by running with --add.

A complex Travis config

• Ruby Travis Config
  • Here you also see some aliases which are very handy if you have specific (and many) system configs but you do not want to run each for each stage
