What I was getting wrong about testing API failure paths

Good. Do these without looking anything up:

1. Explain testing API failure paths in two sentences.
2. Give one situation where you would use it and one where you would not.

I am checking your current model, not your vocabulary. A partial answer is more useful than a polished guess.

That points to a retrieval and boundary problem, not a lack of reading. Use this 25-minute block:

• 5 min: reproduce the behavior in the smallest program.
• 8 min: work one example and say why each step is needed.
• 7 min: predict the result before running it.
• 5 min: add a test for the failure you just found.

Your success test is simple: you can start a fresh example and explain the first decision without a cue. Stop there today. More input would hide whether retrieval improved.

Practice task:

Create a small, realistic example of testing API failure paths from your own work or daily life. State the goal, the evidence or inputs you have, the first decision you would make, and one condition that would make your approach fail.

Check your answer against four things:

• The example is specific enough to test
• The first decision follows from the inputs
• You named a boundary or failure case
• You can explain the choice without repeating a definition

Do not compare with a model answer yet. Take five minutes, then revise once from your own checklist. Tomorrow, redo only the first decision from memory.
