How to write a good bug report

A good starting point would be the [mozilla bug writing guidelines].

Here are some basic principles:

• Be precise
• Be clear - explain it so others can reproduce the bug
• One bug per report
• No bug is too trivial to report - small bugs may hide big bugs
• Clearly separate fact from speculation

Preliminaries:

  1. Reproduce your bug using a recent build of the software, to see whether it has already been fixed.
  2. Search moodle bug tracker, to see whether your bug has already been reported (sometimes might be tricky).
