Description: Isolation testing is a technique used to test a single component or module in isolation from the rest of the system. This approach allows developers and testers to verify the behavior of a specific unit without the influence of other components, making it easier to identify errors and validate internal logic. Isolation testing is fundamental in test-driven development (TDD), where tests are created before implementing the code. By focusing on a single module, external dependencies can be simulated using mocks or stubs, allowing the evaluation of the component’s behavior under various conditions. This technique not only improves software quality but also accelerates the development process by enabling early fault detection. Additionally, isolation testing is essential in automated testing, as it allows for rapid and repetitive test execution, which is crucial in continuous integration environments. In summary, isolation testing is a powerful tool for ensuring that each component of a system functions correctly in isolation, contributing to the overall robustness and reliability of software systems.
