[Feature Request] Effective feature testing automation

[zztin]

Is your feature request related to a problem?

Currently, the feature testing is done by hand & eyes. It is error-prone and time-consuming. It could be ideal to have a set of testing tools to test all the functionalities if they work as expected.

Describe the solution you'd like

Testing includes:
About the app:

• launching app with different options (if they works) --> this can be done with command line check response.

About the functions:

• ticking time (is 1 sec = 1 real sec)
• clock counting
• data recording: if all clocks are recorded (weather pause, stop buttons are pressed during the clock) & whenever the window is closed (also data entries should not be doubled entered.)
