What does 'independence of testing' mean and why is it important?
-'Independence of testing' refers to the degree to which testing is conducted separately from the development process. It is important because it allows testers to have a different perspective, which can lead to the discovery of defects that developers might overlook due to cognitive biases.
What are the four degrees of independence in testing as described in the script?
-The four degrees of independence are: 1) Work products tested by their author, 2) Tested by the author's peer from the same team, 3) Tested by testers from outside the author's team but within the same organization, and 4) Highly independent, where testers are from outside the organization, often in an outsourced scenario.
Why is it beneficial to have multiple levels of independence in testing for most projects?
-Having multiple levels of independence in testing allows for a blend of perspectives and skill sets, which can lead to a more comprehensive testing process. It ensures that different types of defects are caught at various stages by different individuals or teams with varying levels of separation from the development process.
What are some benefits of having independent testers?
-Benefits include the ability to recognize different kinds of failures and detect defects more efficiently due to different technical perspectives and biases, as well as the capacity to verify or challenge assumptions made during the specification and implementation of the system.
What are some drawbacks of having high levels of independence in testing?
-Drawbacks include the potential for independent testers to be isolated from the development team, leading to a lack of collaboration and understanding of the system. Additionally, developers may lose a sense of responsibility for quality, and independent testers may be seen as bottlenecks or blamed for delays in release.
How can the drawbacks of independent testing be mitigated?
-The drawbacks can be mitigated by ensuring prompt communication and collaboration from the beginning of the project, involving developers in testing through activities like unit testing, and by anticipating and addressing potential delays proactively.
