Static analysis tools in Testing Fundamentals - Cheat Sheet & Quick Revision

Recall & Review

beginner

What are static analysis tools in software testing?

Static analysis tools examine source code without running the program. They find errors, bugs, or style issues early, like a spell-checker for code.

beginner

Name two common problems static analysis tools can detect.

They can detect syntax errors and potential security vulnerabilities before the code runs.

How is static analysis different from dynamic analysis?

Static analysis checks code without running it. Dynamic analysis tests the program while it runs to find runtime errors.

beginner

Why is using static analysis tools early in development helpful?

Finding bugs early saves time and cost. Fixing problems before running the program prevents bigger issues later.

beginner

Give an example of a popular static analysis tool.

Examples include SonarQube, ESLint for JavaScript, and Pylint for Python. They help keep code clean and error-free.

What does a static analysis tool do?

A Tests user interface responsiveness

B Runs the program to find errors

C Manually reviews code by a tester

D Checks code without running it

Static analysis tools examine source code without executing it to find errors early.

Which problem can static analysis tools detect?

A Memory leaks during runtime

B Syntax errors

C User experience issues

D Network latency

Static analysis tools detect syntax errors by analyzing code before running.

When is the best time to use static analysis tools?

A During user acceptance testing

B After the program crashes

C Before running the program

D Only after deployment

Static analysis is most effective early, before running the program, to catch issues early.

Which of these is NOT a static analysis tool?

A Valgrind

B Pylint

C SonarQube

D ESLint

Valgrind is a dynamic analysis tool that checks memory during program execution.

Static analysis tools help improve code by:

A Finding bugs early

B Measuring user satisfaction

C Testing hardware compatibility

D Monitoring server uptime

They find bugs early in the code before running, saving time and effort.

Explain what static analysis tools do and why they are useful in software testing.

Think about checking your homework before submitting it.

Compare static analysis and dynamic analysis in simple terms.

One is like proofreading, the other like testing a car by driving it.
