Test Data

The inputs, values, and system state used to execute a test case and verify that software behaves as expected. Test data spans a wide range of forms: valid inputs that exercise the happy path, invalid or boundary inputs that probe edge cases, and pre-existing system state such as user accounts, tokens, or database records that a test depends on. In automated testing, managing test data carefully is critical: each test should operate against a known, isolated set of data, use explicit fixtures or seeded records rather than shared or assumed state, and clean up after itself to avoid polluting subsequent runs. AI-generated automation scripts frequently omit proper test data setup and teardown, making this one of the key areas a human engineer must review and strengthen before the code is considered framework-ready.
