How to Unit test migration functions #391

Closed rowlandekemezie closed 1 year ago

rowlandekemezie commented 3 years ago

We're currently adopting migrate-mongo as our migration tool, but we have concerns about data loss, especially with the down function. Is there a standard or known way to write unit tests for the migration functions(up & down)?

seppevs commented 1 year ago

Some ideas:

You can pass a mocked db in the up and/or down functions of your migration.
You can run your migration against a test database?

I'm closing this, as it is not an issue IMHO.
