Laravel - Browser Tests - Environment Handling

To force Dusk to use its own environment file when running tests, create a .env.dusk.{environment} file in the root of your project. For example, if you will be initiating the dusk command from your local environment, you should create a .env.dusk.local file.

When running tests, Dusk will back-up your .env file and rename your Dusk environment to .env. Once the tests have completed, your .env file will be restored.
