Exploratory Testing

Try these actions to manually explore the app. This is not a strictly ordered list, but a guide meant to spark ideas of how to test/break the app.

Each block below is a grouping of steps meant to test a feature or system capability.

The faster you move through each step in a group, the better. The goal is to put the system under stress, and fast movements usually reveals leaky code that doesn't respond well to unexpected user actions/timing.

You don't need to test every single group for every commit/change - just explore the actions (and their groups) that you guess might have been affected from the latest changes you made in your code.

Every now and then, especially before a big push or Pull Request, try to go through all of the groups/actions.

The whole run through should only take a couple of minutes.

Also, keep an eye on your console.log for unexpected errors, which may signal a problem, even if the UI responds correctly.
