AT*SQA Micro-Credentials - Test Approaches
Test Approaches Micro-Credential
A test approach defines how the testing for a project will be accomplished. As shown through this micro-credential, this approach may be formally defined in the test plan or informally agreed upon by the project team. Approaches can include methods for prioritization (e.g., risk-based) or may specify that certain requirements be met (e.g., regulatory or certification requirements). Test approaches generally reflect the organization’s test strategy and are used to ensure that the methods and goals of testing are aligned with the goals of the project team and the stakeholders.

Test Approaches in Software Development: What QA Teams Need to Know
In software development and quality assurance, various test approaches ensure the quality and reliability of the product. These methodologies pinpoint bugs and errors, vital for optimizing the end-user experience.
AT*SQA's free Test Approaches body of knowledge and optional AT*Learn training webinar give QA teams basic knowledge about test approaches. Below are key points related to test approaches.
Static and dynamic testing form two primary categories of testing. Static testing, a preemptive approach, evaluates code, requirement documents, and design documents without executing the software. Techniques such as reviews, walkthroughs, and inspections are used to detect bugs and errors early, saving both time and cost.
Dynamic testing, conversely, involves running the software and observing its functionality. It can further be broken down into white-box and black-box testing. White-box testing, or structural testing, assesses the internal workings of the software. It utilizes techniques like statement coverage, branch coverage, and path coverage. In contrast, black-box testing focuses on the software's functionality without considering its internal structure. Testing is based on the principle that specific input should yield the expected output, with techniques including boundary value analysis, equivalence partitioning, and state transition testing.
Manual and automated testing also form a critical part of testing methodologies. Manual testing involves manually executing test cases and evaluating the results. Although time-consuming, it is invaluable for exploratory testing, usability testing, and ad-hoc testing. Automated testing, on the other hand, uses automation tools to execute test cases. This approach requires an upfront investment in tools and skilled professionals but proves beneficial for regression testing, load testing, and repetitive test scenarios due to its precision and efficiency.
Within the software development lifecycle, waterfall and agile testing are two key approaches. The waterfall model follows a sequential phase-by-phase approach, with testing being the final stage. Agile testing, however, promotes continuous testing throughout the development process, providing a highly iterative and flexible approach.
Lastly, shift-left and shift-right testing approaches focus on the timing of testing efforts. Shift-left testing calls for early testing in the development process to identify and rectify issues as early as possible. Conversely, shift-right testing focuses on user experience and involves testing in the post-production phase.
Understanding these diverse test approaches and their applicability is essential for effective software testing. Each approach has its strengths and weaknesses, and selecting the right blend can be the determining factor in delivering high-quality, efficient software.
AT*SQA's free body of knowledge provides helpful insights into the different methods, benefits, and potential risks involved in test approaches. For those who prefer to watch a presentation on Test Approaches, AT*SQA also offers the $7.99 per month AT*Learn software testing training area.
After you have learned about test approaches, prove your knowledge with the Test Approaches micro-credential. Like all of AT*SQA's micro-credentials, upon passing, the micro-credential will appear on your profile in the Official U.S. List of Certified & Credentialed Software Testers™ and give you points toward your Testing Tiers® software tester ranking level.
