Lesson 7 of 12
Structured learning draftErrors with API
In Reliable Automation with Make, the way a learner handles errors shapes how API is used and evaluated. An error policy classifies failures as retryable, terminal or reviewable. This beginner lesson focuses on a decision or output that another person can inspect.
Learning objectives
- Explain errors in the context of Reliable Automation with Make.
- Apply API to a bounded practical task.
- Evaluate the result using explicit quality criteria.
Errors: from context to evidence
Errors connects trigger and payload to a observed run in Reliable Automation with Make.
Define the purpose, intended user and API constraints.
Capture safe context and prevent endless retry loops.
Compare the observed result with a normal case, boundary case and stated limitation.
An error policy classifies failures as retryable, terminal or reviewable. For API, distinguish performing an operation from demonstrating that it suits the stated purpose. Capture safe context and prevent endless retry loops. Record assumptions that could change the conclusion.
Apply errors deliberately
- State the Reliable Automation with Make task and the decision it supports.
- Prepare a small API case with a known input and difficult boundary.
- Capture safe context and prevent endless retry loops.
- Compare the observed result with the expected behaviour and explain differences.
- Save the evidence, limitation and next action in a review record.
A worked API evidence path
A four-step worked example for applying errors to API, including a boundary test and revision.
Preserve the original API case and expected result.
Confirm the basic path behaves as expected.
Expose an assumption in the errors method.
Change the method, rerun both cases and record the limitation.
| Review point | Evidence |
|---|---|
| Purpose | The specific API outcome and intended user |
| Method | The errors decision, input and version or context |
| Result | Observed output plus a checked boundary case |
| Limitation | What the result does not establish and the next safe action |
Common mistakes
- Using API before defining what errors must achieve.
- Checking only the easiest Reliable Automation with Make example.
- Reporting a result without its input, assumptions or limitation.
Practice activity
Apply the lesson
For Reliable Automation with Make, complete a bounded API task demonstrating errors. Keep the original input, numbered method, normal test, boundary test, observed results and a 100-word self-review naming one limitation and next improvement.
Check your understanding
In Reliable Automation with Make, which evidence best supports a errors result produced with API?
Lesson summary
- For Reliable Automation with Make, errors means: An error policy classifies failures as retryable, terminal or reviewable.
- A credible API result includes a checked boundary, not only a successful example.
- The next lesson builds on this errors evidence record.
