# Firefox iOS integration tests
To run these tests you will need [Python 3][] and [pipenv][] installed. Once
you have these, make sure you're in the `SyncIntegrationTests` directory and
run the following:
```
$ pipenv install
$ pipenv run pytest
```
The tests will build and install the application to the simulator, which can
cause a delay where there will be no feedback to the user. Also, note that each
XCUITest that is executed will shutdown and **erase data from all available iOS
simulators**. This assures that each execution starts from a known clean state.
