Going on a Testing Anti-Pattern Safari
summary
Catalog of concrete anti patterns and fixes plus measurable wins: tests must be trustworthy and simple; stop testing ActiveRecord (example: asserting find on a created record) and delete useless assertions like assert_nothing_raised; stub time and use relative dates to fix flaky time sensitive tests; randomize order (RSpec --order rand, minitest default) to expose order dependencies; mock external APIs (webmock or a stub Requestor) and cut a 0.25s call to <0.001s; use CI and refuse red builds.
