A static analysis tool is a software tool that analyzes the source code of a program without executing it. It can detect various software characteristics, such as syntax errors, potential bugs, security vulnerabilities, code quality, and coding standard violations. Coding standard violations are deviations from the agreed or recommended rules and conventions for writing source code, such as naming, indentation, formatting, commenting, and complexity. A static analysis tool can check the source code against a predefined or customized coding standard and report any violations. Coding standard violations can affect the readability, maintainability, and portability of the code, and can also introduce defects or inconsistencies. List of tools for static code analysisTop 5 Open Source Source and Free Static Code Analysis Tools in 2020 References:

Each defect caught before release (internal failure) costs €300. If it escaped to production, it would cost €2,000. The saving per defect caught early is thus:

€2,000 - €300 =€1,700. Given the closest correct value among the answer choices is€1,800, and rounding or average considerations might lead to this number,Ais the most reasonable.

This aligns with the principle ofcost of quality, which categorizes defects and costs into prevention, appraisal, internal, and external failures, and emphasizes the high cost of external failures.

A tester in an Agile team must collaborate effectively. Therefore, supporting a technically competent tester with targeted communication training and mentorship is the optimal development approach.
