This GitHub Action installs Bats and the four major bats libraries:

• bats-support
• bats-assert
• bats-detik
• bats-file

The action can be also instructed to select which libraries to install.

         uses: actions/checkout@v2
       - name: Setup Bats and bats libs
         uses: bats-core/[email protected]

For each of the Bats libraries, you can choose to install them in the default location (/usr/lib/bats-<lib-name>) or specify a custom path.

For example, if you want to install bats-support in the ./test/bats-support directory, you can configure it as follows:

# ...
       - name: Setup Bats and Bats libs
         uses: bats-core/[email protected]
         with:
           support-path: ${{ github.workspace }}/test/bats-support

The caching mechanism for the bats binary is always available. However, the caching for the bats libraries is dependent on the location of each library path. If a library is located within the $HOME directory, caching is supported. Conversely, if a library is located outside the $HOME directory (which is the default location per each library), caching is not supported. This is due to a known limitation with sudo and the cache action, as detailed in this GitHub issue: actions/toolkit#946.
