## 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:
|
|
|
|
|
|
|
|
|
|
```shell
|
|
|
|
|
bundle exec rake frontend:fixtures gitlab:graphql:schema:dump
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Then we can use [Jest](https://jestjs.io/) to run the frontend integration tests:
|
|
|
|
|
|
|
|
|
|
```shell
|
|
|
|
|
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`:
|
|
|
|
|
|
|
|
|
|
```shell
|
|
|
|
|
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.
