Static System Tester

A Static System Tester is a tool or software used in software testing to analyze the source code of a system or application without executing it. It helps identify potential defects, vulnerabilities, or coding errors in the codebase.

Static System Testing is a type of testing that focuses on examining the code and related artifacts, such as design documents and requirements, to find issues early in the development process. It is performed before the code is compiled or executed, hence the term "static."

Static System Testers typically perform various analyses on the code, such as:

1. Code review: It involves manually reviewing the code to identify any coding errors, adherence to coding standards, and potential performance or security issues.

2. Code analysis: It involves using automated tools to analyze the code for potential defects, such as unused variables, dead code, or code that violates best practices.

3. Security analysis: It involves scanning the code for potential security vulnerabilities, such as SQL injection, cross-site scripting (XSS), or insecure authentication mechanisms.

4. Complexity analysis: It involves measuring the complexity of the code, such as cyclomatic complexity, to identify areas that may be difficult to maintain or prone to errors.

By performing static system testing, developers and testers can catch potential issues early in the development lifecycle, reducing the cost and effort required to fix them later. It helps improve the overall quality and reliability of the software system.
