Checklist-based testing is a type of software testing based on a pre-planned “to-do” list of tasks called a checklist. Professional testers, who have sufficient technical experience usually complete these lists. QA (Quality Assurance) engineers use such checklists to guide the testing activities.
Very often different software systems are tested in the same way to see whether it is possible to detect the special defects or manage functional conditions and data without addressing to some systematic technique. Such forms of elementary and informal testing are called ad hoc (random) testing. Checklists are used to structure this type of testing in order not to waste time repeating the same tests. Such lists can be online, physical or mental.
Advantages of Using Checklists in Testing
Improved consistency and repeatability: Checklists help ensure that all testers follow the same steps and check the same items, which can help improve the consistency and repeatability of test results.
Reduced risk of overlooking essential items: Checklists can help to reduce the risk of overlooking important things that other testing methods may not cover.
Improved communication and collaboration: Checklists can enhance communication and collaboration among testers, providing a shared understanding of what needs to be tested.
Easier to create and maintain: Checklists are relatively easy to create and maintain, as they can be based on existing documentation, such as requirements documents and user manuals.
Difficulties of Using Checklists in Testing
Upkeep: Checklists require regular maintenance to remain relevant and up-to-date with the evolving software.
Rigidity: Overreliance on checklists may hinder creativity and exploration during testing, potentially missing unexpected issues.
Documentation overhead: Creating and maintaining comprehensive checklists can be time-consuming.
