Identifying Test Condition and Design Test Cases

Test Conditions

A test condition is an item or event that could be verified by one or more test cases, such as a function, transaction, feature, quality attribute, or structural element.

Test conditions are typically identified by analysing:

• Requirements and specifications documents.
• Risk analysis results.
• Architecture and design documents.
• Business processes and use cases.

Designing Test Cases

Once test conditions are identified, they are used to design test cases — a set of preconditions, inputs, actions, and expected results that verify a specific test condition.

• Test Case ID: A unique identifier.
• Preconditions: The state the system must be in before executing the test.
• Test Steps: The exact actions to perform.
• Test Data: The specific inputs used.
• Expected Result: The anticipated outcome if the software works correctly.

Traceability

Good test design maintains traceability between requirements, test conditions, and test cases, ensuring every requirement is covered by at least one test case.
