Frontend Integration Specs
This directory contains Frontend integration specs. Go to spec/frontend if you're looking for Frontend unit tests.
Frontend integration specs:
- Mock out the Backend.
- Don't test individual components, but instead test use cases.
- Are expected to run slower than unit tests.
- Could end up having their own environment.
As a result, they deserve their own special place.
Run frontend integration tests locally
The frontend integration specs are all about testing integration frontend bundles against a mock backend. The mock backend is built using the fixtures and GraphQL schema.
We can generate the necessary fixtures and GraphQL schema by running:
bundle exec rake frontend:fixtures gitlab:graphql:schema:dump
You can also download those fixtures from the package registry: see download fixtures for more info.
Then we can use Jest to run the frontend integration tests:
yarn jest:integration <path-to-integration-test>
If you'd like to run the frontend integration specs without setting up the fixtures first, then you
can set GL_IGNORE_WARNINGS=1:
GL_IGNORE_WARNINGS=1 yarn jest:integration <path-to-integration-test>
The jest-integration job executes the frontend integration tests in our
CI/CD pipelines.
