How were witches teasted?

Various ways:

1. Put in water with stone tied to them if floated witch if sank not witch.

2. Burnt if survived witch if died not witch.

3. If had a black cat witch if not not witch.

4. They weren't.

5. If something had gone wrong near them they were said to be a witch.

6. If voodoo dolls were found in their house.

Ugh... that was boring...
