The test ReleaseNotesTest:testReleaseNotesFilesExistAndAreNotMalformed takes 4 seconds on my machine. Most notably it invokes mb_strlen and assertLessThanOrEqual on each line of some files at the root of the repository. HISTORY has 20000 lines and thus that is rather slow:
You should really fix these slow tests (>50ms)... 1. 3217ms to run ReleaseNotesTest:testReleaseNotesFilesExistAndAreNotMalformed ...
The test should be refactored to do less invocations of assertLessThanOrEqual. For example by keeping track of lines being too long in an array an asserting the array is empty.
