Using matrix jobs

Cloud

Server v4.x

Server v3.x

Use matrix jobs to run multiple OS tests

In the following example, the test job is run across a Linux Docker container, Linux VM, and macOS environments, using two different versions of Node.js. On each run of the test job, different parameters are passed to set both the OS and the Node.js version:

Using Docker? Authenticating Docker pulls from image registries is recommended when using the Docker execution environment. Authenticated pulls allow access to private Docker images, and may also grant higher rate limits, depending on your registry provider. For further information see Using Docker authenticated pulls.
