GitHub Actions workflows fail if any of the steps executes something that returns a non-zero exit code.
Today I learned that
grep returns a non-zero exit code if it fails to find any matches.
This means that piping to grep is a really quick way to write a test as part of an Actions workflow.
I wrote a quick soundness check today using the new
datasette --get /path option, which runs a fake HTTP request for that path through Datasette and returns the response to standard out. Here's an example:
- name: Build database run: scripts/build.sh - name: Run tests run: | datasette . --get /us/pillar-point | grep 'Rocky Beaches' - name: Deploy to Vercel
I like this pattern a lot: build a database for a custom Datasette deloyment in CI, run one or more quick soundness checks using grep, then deploy if those checks pass.
