| * Tests can fail for other reasons than code, it´ because of the animations and espresso sync and | ||
| * emulator state (screen off or locked) | ||
| * <p/> | ||
| * Before all the tests prepare the device to run tests and avoid these problems. | ||
| * <p/> | ||
| * - Disable animations | ||
| * - Disable keyguard lock | ||
| * - Set it to be awake all the time (dont let the processor sleep) | ||
