Static Testing Vs Dynamic Testing (original) (raw)

Last Updated : 13 May, 2026

Static Testing and Dynamic Testing are two important approaches used in software testing to ensure quality.Static testing checks the software without executing the code, while dynamic testing involves running the code. Both are essential for identifying defects at different stages of development.

Helps in early defect detection and quality improvement
Covers both code review and execution-based testing
Used together for complete software validation

Static Testing

Static Testing is the process of evaluating software without executing the code. It focuses on reviewing documents, code, and design to find defects early.

Done without running the program
Includes reviews, inspections, and walkthroughs
Detects errors in early stages (requirements/design phase)

**Example: Reviewing requirement documents or code to identify mistakes before execution.

Dynamic Testing

Dynamic Testing is a software testing method that involves executing the application to evaluate its behavior and validate outputs against expected results. It ensures the system meets business and functional requirements under real operating conditions.

Involves actual code execution using black box or white box techniques.
Helps identify runtime errors, performance issues, and integration defects.

**Example: Testing a login feature by entering username and password.

Static Testing vs Dynamic Testing

Below are the differences between static testing and dynamic testing:

**Parameter	**Static Testing	**Dynamic Testing
**Definition	Detects defects without executing code.	Detects defects by executing the software.
**Objective	Prevent defects early.	Identify and fix defects during execution.
**Stage	Early stages of development.	After code implementation.
**Code Execution	No code execution required.	Requires code execution.
**Deployment	Performed before deployment.	Performed after deployment/build completion.
**Cost	Less costly.	More costly.
**Documents/Artifacts	Uses checklists, reviews, and documents.	Uses test cases and test data.
**Time Required	Takes less time.	Takes more time due to execution.
**Bug Detection	Finds design, documentation, and coding issues.	Finds runtime, performance, and integration issues.
**Techniques	Reviews, walkthroughs, inspections, code reviews.	Functional and non-functional testing.
**Process Type	Verification.	Validation.
