_Note the `TZ=UTC` environment variable which is currently required to get tests working if your system timezone doesn't match UTC._
If you are serving the admin app (e.g., when running `yarn serve`, or when running `yarn dev` in the main Ghost project), you can also run the tests in your browser by going to http://localhost:4200/tests.
This has the additional benefit that you can use `await this.pauseTest()` in your tests to temporarily pause tests (best to also add `this.timeout(0);` to avoid timeouts). This allows you to inspect the DOM in your browser to debug tests. You can resume tests by running `resumeTest()` in your browser console.
When writing tests and not using the `http://localhost:4200/tests` browser tests, it can be easier to have a separate watching build that builds the project for the test environment (this drastically reduces the time you have to wait when running tests):
```bash
yarn build --environment=test -w -o="dist-test"
```
After that, you can easily run tests locally:
Run all tests:
```bash
TZ=UTC yarn test 1 --path="dist-test"
```
To have a cleaner output:
```bash
TZ=UTC yarn test 1 --reporter dot --path="dist-test"
```
This shows a dot (`.`) for every successful test, and `F` for every failed test. At the end, it will only show the output of the failed tests.
To run a specific test file:
```bash
TZ=UTC yarn test 1 --reporter dot --path="dist-test" -mp=tests/acceptance/settings/newsletters-test.js
```
_Hint: you can easily copy the path of a test in VSCode by right clicking on the test file and choosing `Copy Relative Path`._
