Static Testing vs Dynamic Testing - Testing Differences

Software testing is an integral part of the software development life cycle (SDLC). Two types of testing approaches that are commonly used in software testing are static testing and dynamic testing. In this tutorial, we will explore the differences between static testing and dynamic testing.

Understanding Static Testing and Dynamic Testing

Syntax:

Static testing involves examining the software artifacts manually or with the help of tools without executing them. Some examples of static testing include:

• Code reviews
• Walkthroughs
• Inspections

Dynamic testing involves testing the software by executing it. This type of testing can be done manually or with the help of automation tools. Some examples of dynamic testing include:

• Unit testing
• Integration testing
• System testing
• Acceptance testing

Example:

Static testing is the process of reviewing and examining an application's code without executing it. The code is evaluated for maintainability, readability, and other qualities that will ensure the code is well written, efficient, and effective. This is in contrast to dynamic testing, which involves executing the application and checking whether it performs its functionality correctly.

For example, consider a web application that allows users to buy a product. Static testing might focus on reviewing the web page's source code, looking for errors and syntax issues that could result in security issues. Dynamic testing, on the other hand, would involve running the application and verifying that users can create an account, add items to their cart, and successfully check out.

Output:

The output of static testing is typically a report that lists the errors and issues identified during the testing process. In contrast, the output of dynamic testing is typically a list of the failed test cases and the bugs identified during the testing process.

Explanation:

Static testing and dynamic testing are two approaches to testing software applications. Static testing is performed by examining an application's code or documents to identify issues and defects. Static testing is the testing of a system without executing the code.

Dynamic testing is performed by executing tests on the application to verify that it functions correctly. Dynamic testing is the testing of a system whilst it is running.

Use

Static testing and dynamic testing are both important in software testing. Each approach has its advantages and disadvantages, and the choice of approach depends on the needs of the software application and the testing objectives.

Important Points

• Static testing is performed without executing the code, while dynamic testing is performed by executing the code.
• Static testing aims to identify issues such as security vulnerabilities and programming errors.
• Dynamic testing aims to verify the correctness of the code in terms of functionality and performance.

Summary

In this tutorial, we explored the differences between static testing and dynamic testing. We covered the syntax, example, output, explanation, use, and important points of both approaches. Understanding the differences between static testing and dynamic testing can help software development teams choose the right approach for testing their applications. Both forms of testing are valuable in their respective ways and play a vital role in ensuring software quality.
