The subject of the inspection is typically a document such as a requirements document or a test plan. The purpose of an inspection is to find problems and see what is missing not to fix anything. The result of the meeting should be documented in a written report. What is the difference between Static code analysis and code review? What is the difference between static testing and code review? Inspection, code review - is it really testing? Is there a real difference between dynamic analysis and testing?
Verification and validation are not the same, verification shows conformance with the specifications and validation shows that the program meets the customer's need Verification: is a type of static testing as software inspection is convened with analysis of the static system representation to discover problems. Inspection: very technical type of review or testing method, done by the highly technically sound people. Walkthrogh IS informal type of review or testing method. Done by the team lead, so its called peer review. Inspection: very technical type of review or testing method, done by the highly technically sound people.
What is Static Testing?
Under Static Testing, code is not executed. Rather it manually checks the code, requirement documents, and design documents to find errors. Hence, the name 'static'.
The main objective of this testing is to improve the quality of software products by finding errors in the early stages of the development cycle. This testing is also called a Non-execution technique or verification testing.
Static testing involves manual or automated reviews of the documents. This review is done during an initial phase of testing to catch Defect early in STLC. It examines work documents and provides review comments
Examples of Work documents-
- Requirement specifications
- Design document
- Source Code
- Test Plans
- Test Cases
- Test Scripts
- Help or User document
- Web Page content
What is Dynamic Testing?
Under Dynamic Testing, a code is executed. It checks for functional behavior of software system, memory/cpu usage and overall performance of the system. Hence the name 'Dynamic'
The main objective of this testing is to confirm that the software product works in conformance with the business requirements. This testing is also called an Execution technique or validation testing.
Dynamic testing executes the software and validates the output with the expected outcome. Dynamic testing is performed at all levels of testing and it can be either black or white box testing.
Static Testing Techniques:
- Informal Reviews: This is one of the type of review which doesn't follow any process to find errors in the document. Under this technique, you just review the document and give informal comments on it.
- Technical Reviews: A team consisting of your peers, review the technical specification of the software product and checks whether it is suitable for the project. They try to find any discrepancies in the specifications and standards followed. This review concentrates mainly on the technical documentation related to the software such as Test Strategy, Test Plan and requirement specification documents.
- Walkthrough: The author of the work product explains the product to his team. Participants can ask questions if any. A meeting is led by the author. Scribe makes note of review comments
- Inspection: The main purpose is to find defects and meeting is led by a trained moderator. This review is a formal type of review where it follows a strict process to find the defects. Reviewers have a checklist to review the work products.They record the defect and inform the participants to rectify those errors.
- Static code Review: This is a systematic review of the software source code without executing the code. It checks the syntax of the code, coding standards, code optimization, etc. This is also termed as white box testing.This review can be done at any point during development.
Dynamic Testing Techniques:
- Unit Testing: Under Unit Testing, individual units or modules are tested by the developers. It involves testing of source code by developers.
- Integration Testing: Individual modules are grouped together and tested by the developers. The purpose is to determine what modules are working as expected once they are integrated.
- System Testing: System Testing is performed on the whole system by checking whether the system or application meets the requirement specification document.
Also, Non-functional testing like performance, Security Testing fall under the category of dynamic testing.
Difference between Static and Dynamic Testing:
Static Testing | Dynamic Testing |
---|---|
Testing was done without executing the program | Testing is done by executing the program |
This testing does the verification process | Dynamic testing does the validation process |
Static testing is about prevention of defects | Dynamic testing is about finding and fixing the defects |
Static testing gives an assessment of code and documentation | Dynamic testing gives bugs/bottlenecks in the software system. |
Static testing involves a checklist and process to be followed | Dynamic testing involves test cases for execution |
This testing can be performed before compilation | Dynamic testing is performed after compilation |
Static testing covers the structural and statement coverage testing | Dynamic testing covers the executable file of the code |
Cost of finding defects and fixing is less | Cost of finding and fixing defects is high |
Return on investment will be high as this process involved at an early stage | Return on investment will be low as this process involves after the development phase |
More reviews comments are highly recommended for good quality | More defects are highly recommended for good quality. |
Requires loads of meetings | Comparatively requires lesser meetings |
Conclusion:
Verification and Validation are two measures used to check that the software product meets the requirements specifications. Static testing involves verification whereas dynamic testing involves validation. Together they help improve software quality. Learn more about Verification & Validation here
An inspection is more thorough and often aims to serve aspecific purpose, whereas a test is less austere.
A test is usually used to test your skill or knowledge insomething particular depending on what it is.
ex.)'In the Olympics they test whether or not your qualified toenter'
An inspection is to inspect whether or not your qualified orcould be that you are hiding something so they inspect wether ornot you are who you say you are and to make sure your not cheatingin that particular thing.
ex.)'In the Olympics they inspect you to make sure your notusing steroids'
Im not too sure but that would be my best guess. Maybe I'mputting it in the wrong context.
