What is the difference between static testing and dynamic testing in software testing?

Static Testing vs Dynamic Testing in Software Testing

Static testing and dynamic testing are two key approaches to software testing that serve different purposes in ensuring software quality. Here are the main differences between static testing and dynamic testing:

Static Testing

• Static testing is a type of testing that is performed without actually executing the code. It involves reviewing the code, requirements, and design documents to identify issues early in the software development process.
• Static testing is usually performed by humans through techniques such as code reviews, walkthroughs, and inspections.
• The main goal of static testing is to prevent defects from reaching the later stages of development, thus saving time and costs.

Dynamic Testing

• Dynamic testing, on the other hand, involves executing the code and testing the software application against the specified requirements.
• Dynamic testing includes activities such as functional testing, integration testing, system testing, and acceptance testing.
• The main objective of dynamic testing is to validate the behavior of the software and ensure that it meets the desired functionality.

In summary, static testing focuses on finding defects through a manual review process before execution, while dynamic testing involves running the software to validate its functionality against the requirements.

Understanding the differences between static and dynamic testing is essential for software testers to plan and execute appropriate testing strategies for ensuring the quality and reliability of software applications.
