Refactor boards sidebar spec
What does this MR do?
- Uses Timecop to fix due date spec
- Waits for the sidebar to fully visible. This was causing issues where the
Edit
button couldn't be clicked. Sidebar is shown with a CSS transition so needs to be fully open before clicking anything - Fixes a weird issue where the link inside the card would be clicked instead of the card itself to open the sidebar
- Slightly increase the speed the test runs at
