What is a primary purpose of tool support in testing?

The primary purpose of tool support in testing is to automate activities that cannot be performed manually. In the software testing lifecycle, many tasks require a significant amount of time and precision, making automation essential. Tools can execute repetitive tests or complex scenarios efficiently, allowing testers to focus on analysis and judgement rather than on tedious execution. This automation not only increases efficiency and accuracy but also helps in maintaining consistency across tests, ultimately improving the overall quality of the software product.

While other options may involve certain aspects related to testing and software development, they do not align with the core objective of tool support in the context of optimizing the testing process. Increasing manual labor contradicts the very essence of automation, and while communication strategies and software interface appearance are important in the broader scope of software development, they are not the fundamental purpose of using testing tools.
