Static Testing vs Dynamic Testing

Introduction to Static Testing vs Dynamic Testing

Both static testing and dynamic testing are important testing methods that are used by developers and testers to test the functionality and quality of the software. each testing type has its advantages and risk factors, based on the testing of product or application, the developer or tester chooses the right technique to test the application at each stage of the development life cycle.

Head to Head Comparison Between Static Testing vs Dynamic Testing (Infographics)

Below are the top 9 differences between Static Testing vs Dynamic Testing:

Static Testing

Static testing is a type of testing where code is not executed, it is done manually or using a set of tools. It is used to check the document requirements, code, design documents and maintain an review for each document. It starts earlier in the development life cycle, hence it is also called verification testing. static testing can be performed on work documents such as requirements specification, design documentation, test plan, source code, test cases, test scripts, web page content. Static testing techniques are as follows

• Inspection: It is a type of review where a checklist is created to review the document. The purpose is to find the defects.
• Walkthrough: In this technique, the leader conducts a meeting to explain the product.
• Technical reviews: This technique is used to determine whether code matches the technical requirements and standards or not.
• Informal reviews: In this technique, the document is reviewed informally and informal comments are given

Dynamic Testing

Dynamic testing is done in a runtime environment when code is in operation mode. When code is executed with input value, the output of the code is then checked and compared with the expected results. It is performed at the validation stage, hence dynamic testing is also called validation testing. functional testing and non-functional testing are the types of dynamic testing.

Types of dynamic testing techniques are as follows

• Unit testing: Unit testing is used to test the individual part of the system
• Integration testing: It is used to test the interface between different modules.
• Acceptance testing: It is done from the user’s point of view.
• System testing: It is used to test the system as a whole.

Comparison Table of Static Testing vs Dynamic Testing

Static Testing	Dynamic Testing
Static testing is a white box testing that is performed at the early stages of the development life cycle.	Dynamic testing is performed at a later stage of the development life cycle.
Static testing is more cost-effective than dynamic testing.	Dynamic testing is less cost-effective than static testing.
Static testing is done before the code development.	Dynamic testing is done after the code development.
A number of statement coverage is more in static testing as it covers all the code areas.	A number of statement coverage is less in dynamic testing as it covers only a limited area of the code.
static testing is performed without execution of the code.	Dynamic testing is performed with the execution of the code.
It gives the assessment of the code and documentation.	It gives bottlenecks to the software systems.
A verification stage, static testing is performed	At the validation stage, dynamic testing is performed.
walkthrough and code review techniques are used to perform the static testing.	Functional testing and nonfunctional testing techniques are used to perform dynamic testing.
In Static testing, the testing process involves the preparation of a checklist.	In dynamic testing, the testing process involves the execution of test cases.

Key Differences between Static Testing vs Dynamic Testing

Key differences between static testing and dynamic testing are as follows:

• Static testing is carried out at the early stage of the development cycle, while dynamic testing is carried out at a later stage of the development life cycle.
• Static testing can be done manually or by using a set of tools, while dynamic testing is performed in the runtime environment.
• static testing is performed at the verification stage, while dynamic testing is performed at the validation stage.
• Before code development, static testing is done, while dynamic testing is done after the code development.
• static testing is performed without execution of the code while as dynamic testing is done by executing the code.
• static testing is used to find out the errors, code flows, potentially malicious code in the application whereas
• dynamic testing is used to find out the functional behavior of the software, CPU response time, monitoring memory of the system, performance of the system.

Conclusion

Both static testing and dynamic testing are used to check the software or product. Each has its own advantages and disadvantages. One type is for verification and another is used for verification. Based on the specific requirements and test needs. one can adopt one of these methods to test the product or software.
