A Test Case is a set of conditions or variables used to determine if a system behaves as expected. It includes preconditions, inputs, actions, expected results and postconditions.
Components of a Test Case:
- Preconditions: Conditions that must be met before executing the test.
- Inputs: Data provided to the system during testing.
- Actions: Steps taken during the test execution.
- Expected Results: The anticipated outcome if the system functions correctly.
- Postconditions: The state of the system after executing the test.
Test cases are essential for validating software functionality and ensuring quality throughout development.
