Differences between static testing and dynamic testing?

Define static testing

Answer1: In software development, static testing, also called dry run testing, is a form of software testing where the actual program or application is not used. Instead this testing method requires programmers to manually read their own code to find any errors.
Static testing is a stage of White Box Testing

Answer2
The Verification activities fall into the category of Static Testing. During static testing, you have a checklist to check whether the work you are doing is going as per the set standards of the organization. These standards can be for Coding, Integrating and Deployment. Review's, Inspection's and Walkthrough's are static testing methodologies.


Differences between static testing and dynamic testing

Q: What is the difference between static and dynamic testing?

Difference number 1: Static testing is about prevention, dynamic testing is about cure.

Difference number 2: The static tools offer greater marginal benefits.

Difference number 3: Static testing is many times more cost-effective than dynamic testing.

Difference number 4: Static testing beats dynamic testing by a wide margin.

Difference number 5: Static testing is more effective!

Difference number 6: Static testing gives you comprehensive diagnostics for your code.

Difference number 7: Static testing achieves 100% statement coverage in a relatively short time, while dynamic testing often often achieves less than 50% statement coverage, because dynamic testing finds bugs only in parts of the code that are actually executed.

Difference number 8: Dynamic testing usually takes longer than static testing. Dynamic testing may involve running several test cases, each of which may take longer than compilation.

Difference number 9: Dynamic testing finds fewer bugs than static testing.

Difference number 10: Static testing can be done before compilation, while dynamic testing can take place only after compilation and linking.

Difference number 11: Static testing can find all of the followings that dynamic testing cannot find: syntax errors, code that is hard to maintain, code that is hard to test, code that does not conform to coding standards, and ANSI violations.
