What is the feature of a test case?

A test case is a set of steps to verify a specific function of software, including preconditions, input data, expected results, and postconditions. Its features are:

• Well-structured: A sequence of actions to be performed.
• Reproducible: Any tester can execute it and get the same result under the same conditions.
• Atomic: Focused on testing a specific aspect of functionality.
• Contains expected result: Allows unambiguous determination of whether the test passed or failed.

An example of a simple structure:

• ID: Unique identifier.
• Name: Brief description of the functionality being tested.
• Priority: Importance of the test.
• Preconditions: Conditions that must be met before starting the test.
• Execution steps: Sequence of user actions.
• Input data: Data used in the steps.
• Expected result: What the result should be after executing the steps.
• Postconditions: System state after the test.

Using test cases ensures a unified approach to testing, facilitates progress and quality tracking, and serves as documentation of functionality.
