Continuous Integration with Travis CI

Integrating Prism into your Travis CI pipeline is easy. The simplest way to get up and running is by using Stoplight’s Prism Docker image.

To get started, you will need to make sure the docker service is listed under the services section of your .travis.yml file.

When integrating Prism into a Travis CI pipeline, there are two different approaches:

  • Starting Prism in the background to act as either a mock or contract/validation server
  • Having Prism conduct a scenario against a running server by running as a dedicated test step (i.e. added to the script section)

Running Prism in the Background

Below is a sample Travis CI configuration file using Prism as a mock or contract/validation server:

    - docker

    # start the mock server in the background
    - docker run -d -p stoplight/prism mock ...

Once the Prism container is started, it will automatically start listening on http://localhost:4010 for any open connections.

Running Prism in the Foreground

Below is a sample Travis CI configuration file with Prism conducting a scenario:

    - docker

    - docker run --rm -it stoplight/prism conduct ...

When running prism conduct you can:

  • Include the Scenario JSON on your CI server, and pass in its absolute file path
  • Pass in the absolute URL to the scenario JSON served up via HTTP

Don’t forget to pass in any required environment values with the --env command line flag (or you can provide the filepath to a json file with your environment variables)!

Did you know? You can find the full command to run your scenario collection or individual scenarios in the Stoplight application. Click on the “Home” button of a scenario under “Trigger This Collection”.
