# Multiplying the quality of unit tests
An Android project to showcase how to improve our unit tests step by step:
1. From tests *multiple assertions* to *parameterized example-based tests*,
2. Add extra *property-based tests* to catch regression bugs that *parameterized tests* cannot.
3. Advanced use of *property-based tests* for stateful testing:
verify that the state of our model is correct after performing any action on it.
For 1. & 2, we test the logic behind the **strong password validator** of a [**create account**](https://github.com/sergio-sastre/Multiplying_the_quality_of_unit_tests/tree/master/passwordvalidator) screen.
For 3, we test that the state of a [**text editor**](https://github.com/sergio-sastre/Multiplying_the_quality_of_unit_tests/tree/master/texteditor) (i.e. displayed text & text to display upon undo/redo actions) is correct after editing, undoing and redoing in any *random order*.
