How to kill a working automation

You want to kill your automated tests. Here are the best approaches:

• Do not fix bat blocking bugs. This will cause test to become red-ish and unusable after awhile 
• Do worthless UI changes. Do them right before the release.
• After tests is already working do not plan and spend time to support them.  

So it is easy ... Any of the above can easily kill your automation. If you want everything to finish fast just use all them at once.
