Formal style guidelines and mandatory tests for everything are largely wastes of time and often detrimental to software development.

To elaborate: formal style guides prevent simple things like formatting code in a manner that is easier to read in some cases (“why is this newline here? Why did you column aligned this block of expressions?”), and more insidiously force you to write worse code because they constrict you. Style guidelines should be just that - guidelines and engineers should have the decency to not request stylistic changes during code reviews unless they spot code that is obviously sloppy.

As for tests: insisting on having tests for everything impedes development in the present as well as in the future. More crucially the compulsive desire to have everything testable makes you write worse code as you need to abstract away parts that would simply be function calls or use patterns that obfuscate the code. Some will claim that this results in better designed code, but realistically speaking it just results in more complex code, which is almost always worse. You don’t need to use abstractions everywhere. Developers should focus on making shit work well and not over engineering code because they want to feel smart all the while making rationalizations about testable code and whatnot. I digress though so back to my original point regarding tests: in order for tests to justify their existence they have to test something significant and/or test a module that provides a service (read: hidden behind well defined API, api which you test to ensure that it doesn’t break its “contract”)
