-
-In general, use one blank line to separate things within one group of things, and two blank lines
-to separate groups. In rare cases, when methods are tightly coupled and are only helpers for another
-method, they may follow the calling method without separating blank lines.
-
-## Tests
-
-Test classes should be in the appropriate directory (see existing tests) and in the same package as the
-tested class. Tests are usually be named like `methodToBeTested_Condition()`, see
-[Test apps on Android](https://developer.android.com/training/testing/).
