Tell me about static testing.

Answer from AI
Static testing is a software testing method performed without executing the application code. Its goal is to detect defects early in the development lifecycle stages, such as requirements, design, and source code.
Main techniques:
- Code analysis:
- Static analysis: Checking code with automated tools for compliance with coding standards, potential vulnerabilities, unhandled exceptions, and other issues.
- Inspections, Walkthroughs, Reviews: Formal processes of analyzing documentation and code by a team aimed at finding errors.
- Documentation analysis: Testing development artifacts such as requirements, design specifications, and user documentation for completeness, consistency, and ambiguity.
Advantages:
- Early defect detection reduces the cost of fixing them.
- Improved quality of code and documentation.
- Reduction in time and resources needed for dynamic testing.
- Knowledge transfer and training of new team members through review processes.
Disadvantages:
- Cannot detect defects related to system behavior during execution (e.g., performance issues, component interaction errors).
- Can be labor-intensive, especially for formal review processes.
- Static analysis results may contain false positives.
Examples of static code analysis tools:
- Java: SonarQube, PMD, Checkstyle
- Python: Pylint, flake8, Bandit
- JavaScript: ESLint, JSHint
- C#: StyleCop, FxCop
Static testing is an important part of a comprehensive testing strategy and complements dynamic testing by identifying a significant portion of defects before the code execution stage.
