Why test each method immediately?
Short answer. So you know exactly which new code broke something.
Why keep the last working version?
So a new mistake cannot ruin work that already worked.
Remember
| One method, one test |
| Keep the working copy |
You typed the whole project, and nothing works. Where is the bug? Build one method at a time. Test it with numbers you can check by hand. Then start the next. One method, then one test. Keep a working copy.
