Study Notes
Validating the Requirements
- Validation involves test activities beginning in parallel with corresponding development activities.
- Acceptance tests are derived from user requirements.
- System tests are based on functional requirements.
- Integration tests are based on the system's architecture.
Key Actions in Validation
- Reviewing requirements (peer review, rigorous inspection, etc.).
- Testing the requirements for documenting the expected behavior under specified conditions.
- Defining acceptance criteria together with users and based on their requirements.
- Simulating the requirements (simulations with mock-ups to validate requirements and make design choices if necessary).
Good Practices of Requirements Validation
- Reviewing requirements is a powerful technique for identifying ambiguous or unverifiable requirements.
- Reviewing requirements helps identify requirements that aren't defined clearly enough for design to begin.
- Reviewing requirements also helps identify other problems.
Reviewing Requirements
- Peer review of requirements, particularly the type of rigorous review called inspection, is one of the highest-value software quality practices available.
- Assemble a small team of reviewers who represent different perspectives (analyst, customer, developer, tester).
- Carefully examine the written requirements, analysis models, and related information for defects.
- Informal preliminary reviews during requirements development are also valuable.
Defining Acceptance Criteria
- Ask users to describe how they will determine whether the solution meets their needs and is fit for use.
- Acceptance criteria include a combination of the software passing a defined set of acceptance tests based on user requirements.
Simulating the Requirements
- Commercial tools are available that allow a project team to simulate a proposed system either in place of or to augment written requirements specifications.
- Simulation takes prototyping to the next level, by letting BAs work with users to rapidly build executable mock-ups of a system.
Testing the Requirements
- Tests constitute an alternative view of the requirements.
- Writing tests requires you to think about how to tell if the expected functionality was correctly implemented.
- Derive tests from the user requirements to document the expected behavior of the product under specified conditions.
- Walk through the tests with customers to ensure that they reflect user expectations.
