Testability is the degree to which a system or component can be effectively tested. It highlights the key attributes of testability, such as observability, controllability, and isolatability.
Testability directly impacts the reliability of software systems. It emphasises that investing in testability upfront saves time and effort in the long run, leading to improved software reliability.
Designing software with testability in mind is essential. There are principles and techniques for enhancing testability, such as modular design, loose coupling, and clear interfaces.
This slide introduces testability metrics used to quantify the testability of software systems. It presents metrics like cyclomatic complexity, code coverage, and fault seeding.
This slide explores techniques and tools that enhance testability. It covers techniques such as mocking, stubbing, and dependency injection, along with testing frameworks and automation tools.
The final slide highlights best practices for incorporating testability into software development. It includes strategies such as involving testers early in the development cycle, establishing clear requirements and test objectives, and maintaining a comprehensive test suite.
Testability is a critical factor in achieving software reliability. By understanding the concept of testability, designing for testability, measuring testability metrics, leveraging testability techniques and tools, and implementing testability best practices, testing teams can improve the reliability of their software products.
