Identifying Bugs with Integrated Tools in an IDE

Question

A development team is testing an in-house-developed application for bugs.

During the test, the application crashes several times due to null pointer exceptions.

Which of the following tools, if integrated into an IDE during coding, would identify these bugs routinely?

B.

The tool that can identify null pointer exceptions during coding is a Static code analyzer, therefore, the correct answer is B.

A static code analyzer is a software tool that analyzes source code to find defects or security vulnerabilities before the code is executed. It is also known as a source code analyzer or static analysis tool. It is often used in software development to improve code quality, reduce errors, and ensure compliance with coding standards.

A null pointer exception occurs when a program attempts to use a null object or reference, which means the reference does not point to any object in memory. This results in a runtime error that causes the application to crash. To avoid null pointer exceptions, developers need to ensure that all object references are properly initialized and not null.

Integrating a static code analyzer into the integrated development environment (IDE) during coding can help identify null pointer exceptions and other potential issues before the code is compiled and executed. The tool will scan the source code and look for patterns that could cause null pointer exceptions, such as uninitialized variables or parameters. It will also check for other coding errors and security vulnerabilities.

An issue tracker is a tool used to track and manage software bugs and feature requests. It is used to create, assign, and prioritize issues, and to track their resolution. However, it does not identify the issues automatically during coding.

A source code repository is a tool used to store and manage source code files. It is used to keep track of changes made to the code over time, and to collaborate with other developers. However, it does not identify coding issues automatically.

A fuzzing utility is a software testing technique that involves inputting random data into an application to see if it causes unexpected behavior. While fuzzing can help identify some types of bugs, it is not specifically designed to identify null pointer exceptions.
