Analysis:
Understanding the roles and functionalities of component testing tools and build automation tools is crucial for effective software development and testing processes.
B: In a full continuous integration process, build automation tools are typically used to trigger the builds by every commit to a repository:
* This is a fundamental function of build automation tools in continuous integration environments. They automatically trigger builds whenever code changes are committed to the repository, ensuring that the codebase is continuously tested and integrated.
Explanation of Incorrect Options:
* A. Build automation tools allow users to change variable values during execution and step through the code of each component line by line:
* This describes a function of debugging tools, not build automation tools.
* C. Build automation tools cannot be used to periodically schedule the builds, for example during the night:
* This is incorrect as build automation tools can indeed schedule builds at specified times.
* D. Component testing tools are not used for writing tests at component level but to automate the component testing:
* Component testing tools are used for writing and automating tests at the component level.
