Nice work getting this pull request opened!

This pull request adds a .travis.yml configuration file. This file is necessary to return a successful build. This configuration file is where we define how we want to build and test the code.

All projects have different needs, ranging from standard unit tests to custom configuration. Regardless of the definition of "success" for your project, this is the place to define it.

There isn't much in this file right now, but we're going to change that. We'll make a change to configure the build environment.

You might be noticing a few things about this configuration file, like the programming language.

You can trigger Travis CI builds with new commits. To trigger Travis CI, add the below text in place of the replace me with rvm placeholder:

2.5

Step 2: Specify the Ruby version

To get the CI build to succeed, replace the placeholder text and commit the change.

⌨️ Activity: Define a specific version of a language

1. In this pull request, replace the placeholder text with 2.5. You can do this by editing the file from the Files changed tab, or by scrolling down and accepting the suggested change.

Nice work getting your CI build to succeed! 🎉

Notice that your pull request shows all checks have passed with 2 successful checks.

You'll notice that there are two build status checks. One build is for the branch and the other build is for the pull request (more accurately, the merge of your initial-travis-config branch into the base branch main).

Why did my CI build succeed?

The .travis.yml file defines your build environment and which automated tests to run. The entire delivery process is defined through this single .travis.yml file. If this file is present and your commit passes the tests as outlined in the .travis.yml file, your CI build will succeed.

Step 3: Merge the configuration

Now that our CI build is succeeding, merge this pull request so the .travis.yml file is pushed to main.

⌨️ Activity: Share your configuration with the team by merging it

1. Click merge pull request, and delete your branch

The .travis.yml file treats configuration and build environments as code. Version control is an important part of secure collaboration for code. Configuration as code adds the benefits of Git version control for test and build environments.

Now that your CI build is succeeding, let's add some validations to your project.
