Module 4: Testing and Completion

You have built the application feature by feature. The final step is not another large code block—it is proving that the pieces work together.

What to expect

You will run through a practical test plan covering:

• password length and character selection
• empty selections and short lengths
• strength feedback
• current-password and history copying
• five-item history limits and persistence
• clearing stored history
• theme persistence
• Tips modal open/close behavior
• Dice Mode
• browser console errors and regressions

The goal is to test behavior from the learner’s point of view first, then use the console and code to diagnose failures.

A useful habit

Do not assume a feature still works because the lesson that introduced it passed. Later features reuse earlier functions. For example, Dice Mode depends on generatePassword(), and history depends on generation. Retest those workflows after changes.

Completion standard

When this module is finished, you should be able to open SecureGen in a fresh browser session and demonstrate every major control without editing the code while testing.
