Code Guidelines

UI

• Avoid calling anything that triggers a forced reflow. If you can't avoid it, try to call as infrequently as possible https://gist.github.com/paulirish/5d52fb081b3570c81e3a

Refactoring

• If you are moving/renaming files or methods as part of refactoring it should be done in a separate standalone PR before making other changes. This simplifies the changeset for reviewers and creates a relatively safe commit that can be pulled into other active branches.

Tests

Tests should be independent and work correctly when run individually or as a suite.

• it blocks should only contain assertions and should not modify the DOM or app state.
• it blocks should not be dependent on previous it blocks at the same depth. If you are testing a sequence of events use nested describe blocks example
