What does the test>artifacts section of build settings represent for an Angular project?

```
test:
phases:
preTest:
commands:
- wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm
- yum install -y ./google-chrome-stable_current_*.rpm
- npm ci
test:
commands:
- npm run test:ci
artifacts:
baseDirectory: ???
files:
- '**/*'
```
`"test:ci": "ng test --no-watch --no-progress --browsers ChromeHeadlessCI",
`

Is it meant to define where all your tests are located? Or is it meant to define where the output artifacts will go after your tests are run? What if my tests don't have an output artifacts (as is the case above), what should I put here?

Start with the test.phases.artifacts section of the build settings and the provided npm run test:ci command, which runs ng test with ChromeHeadlessCI. Confirm whether baseDirectory describes test output or test locations, and document what to configure when the test command produces no artifacts.
