checking that specific repository methods were called.
## Screenshot tests
**Now In Android** uses [Roborazzi](https://github.com/takahirom/roborazzi) to do screenshot tests
of certain screens and components. To run these tests, run the `verifyRoborazziDemoDebug` or
`recordRoborazziDemoDebug` tasks. Note that screenshots are recorded on CI, using Linux, and other
platforms might generate slightly different images, making the tests fail.
# UI
The app was designed using [Material 3 guidelines](https://m3.material.io/). Learn more about the design process and
obtain the design files in the [Now in Android Material 3 Case Study](https://goo.gle/nia-figma) (design assets [also available as a PDF](docs/Now-In-Android-Design-File.pdf)).
