Testing Permissions
What evidence shows that the paid workflow works under normal, invalid, duplicate, and unavailable-service conditions? Build a role-and-resource matrix and test both permitted and forbidden cases at the backend boundary.
What You Will Be Able to Decide
- Explain testing permissions in product and business terms.
- Apply this decision: Build a role-and-resource matrix and test both permitted and forbidden cases at the backend boundary.
- Recognise this material risk: the interface hides an action but the API still allows it for another user's resource.
- Use this review: Repeat a report purchase with a failed payment, a refresh after checkout, and a delayed delivery before release.
A founder needs evidence that the product works beyond the most convenient demonstration path. This lesson gives you a concrete question to take into a build brief, proposal review, or product decision.
What evidence shows that the paid workflow works under normal, invalid, duplicate, and unavailable-service conditions? The course example is A paid report service with sign-in, checkout, and report delivery; use it to decide what evidence would justify the choice before a builder implements it.
What Does Testing Permissions Mean for Your Product?
A founder needs evidence that the product works beyond the most convenient demonstration path.
Use the illustrative service for this course (A paid report service with sign-in, checkout, and report delivery) to make the choice concrete. What evidence shows that the paid workflow works under normal, invalid, duplicate, and unavailable-service conditions?
Technical term
Testing Permissions
Permission testing verifies that each identity can perform only allowed actions on allowed resources, including through direct requests.
How Should a Founder Use Testing Permissions?
For a paid report service with sign-in, checkout, and report delivery, ask what would happen if the interface hides an action but the api still allows it for another user's resource.
For this decision, the useful standard is that the same expected result can be reproduced under normal, invalid, and failure conditions.
- Decision: Build a role-and-resource matrix and test both permitted and forbidden cases at the backend boundary.
- Evidence to request: show that the same expected result can be reproduced under normal, invalid, and failure conditions.
- Owner: name who will respond if the interface hides an action but the api still allows it for another user's resource.
- Record the result in the test plan and recorded evidence.
- Practical review: Repeat a report purchase with a failed payment, a refresh after checkout, and a delayed delivery before release.
How Do You Choose an Approach to Testing Permissions?
What evidence shows that the paid workflow works under normal, invalid, duplicate, and unavailable-service conditions? Build a role-and-resource matrix and test both permitted and forbidden cases at the backend boundary.
The risk is that the interface hides an action but the api still allows it for another user's resource. Compare a simpler option with the proposed one, including who will operate either choice.
- Describe the user or business outcome that must be protected.
- Identify the most credible failure and its consequence.
- Compare the simplest adequate approach with one realistic alternative.
- Set a review point for when the decision may need to change.
What Evidence Should You Accept for Testing Permissions?
What Warning Signs Should You Look For?
- The proposal does not address this risk: the interface hides an action but the API still allows it for another user's resource.
- Nobody can show whether the same expected result can be reproduced under normal, invalid, and failure conditions.
- The decision has no named owner or review point.
What Should You Ask a Consultant?
- What changes for the user if we choose this approach to testing permissions?
- How have we reduced or accepted this risk: the interface hides an action but the API still allows it for another user's resource.
- Can you demonstrate that the same expected result can be reproduced under normal, invalid, and failure conditions?
- Who owns the result, and when will we reconsider it?
Key takeaway
Key Takeaway
Build a role-and-resource matrix and test both permitted and forbidden cases at the backend boundary. Ask for evidence against the specific risk: the interface hides an action but the API still allows it for another user's resource.
