Versions

vertest --versions=latest-minors

Allows you to specify which versions of a package to include in the test matrix according the semver format (<major>.<minor>.<patch>).

⚠️ BE AWARE: The number of entries in the matrix is multiplicitive, so choosing a version mode that matches many versions can result in a very large test matrix!

Examples of versions matching each version mode

Progress renderer

vertest --progress=silent

Listr is used to render the test progress. The following renderers are available for Listr:

• silent - No output
• update - Re-rendering progress list with spinners (default)
• verbose - Sequential logs with timestamps

Epilogue renderer

vertest --epilogue=verbose

• silent - No output
• failures - Test output for failures only (default)
• verbose - Test output for passes/failures and tests skipped due to engine/peer incompatibility

Dependencies

By default only peerDependencies are used to generate the test matrix. dependencies and optionalDependencies are also available to be used.

⚠️ BE AWARE: The number of entries in the matrix is multiplicitive, so adding dependencies can result in a very large test matrix!
