It is a good idea to test your project systematically. We recommend using a shared spreadsheet that all testers report bugs on - here is an example:Testing Spreadsheet
We also recommend creating a testing manual to guide your testers on how to use the intervention, and what to test. Here is an example:Testing Manual
The example file guides the tester on where to go and how to record goal reviews and feedback. If your intervention has complex features, create testing manuals to test each feature, rather than asking the tester to do everything at once.
