This means that configuration backend tests no longer use stubs and
(mostly) avoid internal dependencies in the tests. Instead of stubs and
mock-fs, the tests use [testfs](https://github.com/balena-io-modules/mocha-pod#working-with-the-filesystem)
which allows working with a real filesystem and ensuring everything is
re-set between tests.
This is the last change needed in order to be able to merge #1971. Here is the list of changes
- [x] Migrate splash image backend tests
- [x] Migrate extlinux backend tests
- [x] Migrate config.txt backend tests
- [x] Migrate extra-uenv config tests
- [x] Migrate odmdata config tests
- [x] Migrate config utils tests
- [x] Migrate device-config tests
Change-type: patch
Update-lock tests now use the actual filesystem for testing, instead of
relying on stubs and spies.
This commit also fixes a small bug with update-lock that would cause a
`PromiseRejectionHandledWarning` when the lock callback would throw.
This also needs to modify the test environment as database migrations
will look for `config.json` in the location given by the variable
`CONFIG_MOUNT_POINT`.
The volume tests now run against the actual docker engine setup via dind
Change-type: patch
This allows to run integration tests during development and on CI
with the right dependencies. There are several changes that this
involves, but the gist of it is that a test environment is setup using
`docker-compose.test.yml`. This file is loaded by `resin-ci` during the
build, and ensures that integration tests are ran after setting up all
requirements. This commit also defines a test environment command that
can be setup using `npm run test:env` in order to run tests in a local
development machine.
