Testing OneToGo

OneToGo uses both Jest (opens in a new tab) and Cypress (opens in a new tab) for testing. Jest is used for unit testing and Cypress is used for end-to-end testing.

Unit testing with Jest

To run the unit tests, run the following command in the root directory of the project:

npm run test

This will run all the unit tests in the project.

As a standard practice, all unit tests are written in the same directory as the component they are testing. For example, the unit tests for the App component are written in src/components/App/App.test.ts.

End to end testing with Cypress

Running end to end tests requires the application to be running in test mode and also requires the Firebase Emulators to be running.

First, run the emulators:
```
npm run emulators
```
Then, run the application in test mode:
```
npm run cypress
```

A browser window will open with the Cypress test runner. Click on the test you want to run and it will run in the browser window.

As a standard practice, all end to end tests are written in the cypress/ directory. For example the end to end tests for the App component are written in cypress/e2e/App.cy.ts.
