Add a test for the migration of the db between versions
2020-11-17 14:33:09 +01:00
# Test that we can successfully migrate from an older db schema
# Only run this if we have an older Nix available
Fix the db-migration test

# XXX: This assumes that the `daemon` package is older than the `client` one
Harden tests' bash Use `set -u` and `set -o pipefail` to catch accidental mistakes and failures more strongly. - `set -u` catches the use of undefined variables - `set -o pipefail` catches failures (like `set -e`) earlier in the pipeline. This makes the tests a bit more robust. It is nice to read code not worrying about these spurious success paths (via uncaught) errors undermining the tests. Indeed, I caught some bugs doing this. There are a few tests where we run a command that should fail, and then search its output to make sure the failure message is one that we expect. Before, since the `grep` was the last command in the pipeline the exit code of those failing programs was silently ignored. Now with `set -o pipefail` it won't be, and we have to do something so the expected failure doesn't accidentally fail the test. To do that we use `expect` and a new `expectStderr` to check for the exact failing exit code. See the comments on each for why. `grep -q` is replaced with `grepQuiet`, see the comments on that function for why. `grep -v` when we just want the exit code is replaced with `grepInverse, see the comments on that function for why. `grep -q -v` together is, surprise surprise, replaced with `grepQuietInverse`, which is both combined.

Allow running all the tests with the daemon When `NIX_DAEMON_PACKAGE` is set, make all the tests use the Nix daemon. That way we can test every piece of Nix functionality both with and without the daemon. Tests for which using the daemon isn’t possible or doesn’t make sens can selectively be disabled with `needLocalStore`
