 ### How to avoid blinking tests?
 
 - Always call `super.tearDown()` inside `finally {..}` block of your test class to avoid leaks and side-effects from previously run (failed) tests.
-- Avoid OS-specific assumptions (e.g., filesystem case-sensitivity, use `java.io.File.separator`).
-- Use _ordered_ collections if necessary or use [`UsefulTestCase#assertUnorderedCollection()`](upsource:///platform/testFramework/src/com/intellij/testFramework/UsefulTestCase.java).
-- Code deferring execution (e.g., via `Application#invokeLater()`) might not run during test execution (and possibly fails in production, too). Use `invokeLater(runnable, myProject.getDisposed()`.
