Conclusion
Weekend testing is an interesting evolution in software testing, but its scope is currently limited to projects involving plain vanilla testing, wherein traditional models such as Waterfall and V are employed. It definitely provides advantages, such as a larger and more diverse knowledge base and increased tester experience, which lead to effective testing.
With the latest advances, such as DevOps relying heavily on automation tools, the scope for weekend testers may be limited. Weekend testing teams lack a defined structure and process and may not be able to win over the confidence of the customer. However, if a large testing organization leverages the weekend testing concept for areas such as IoT and ensures adequate governance and accountability, the concept can be employed with confidence.
