 ## ⚪ ️  1.4 Stick to black-box testing: Test only public methods
 
-:white_check_mark: **Do:** Testing the internals brings huge overhead for almost nothing. If your code/API deliver the right results, should you really invest your next 3 hours in testing HOW it worked internally and then maintain these fragile tests? Whenever a public behavior is checked, the private implementation is also implicitly tested and your tests will break only if there is a certain problem (e.g. wrong output). This approach is also referred to as `behavioral testing`. On the other side, should you test the internals (white box approach) — your focus shifts from planning the component outcome to nitty-gritty details and your test might break because of minor code refactors although the results are fine - this dramatically increases the maintenance burden
