In software development, ensuring quality is paramount. Two key testing approaches—static testing and dynamic testing—play distinct yet complementary roles in achieving this goal. This article provides a clear, professional overview of both methods, their differences, and their applications, ideal for teams seeking to understand their testing options.
What is Static Testing?
Static testing involves evaluating software artifacts, such as code or documentation, without executing the program. It focuses on identifying defects early in the development process through manual or automated reviews.
Key Characteristics
No Execution: Analyses code, requirements, or designs without running the software.
Techniques: Code reviews, walkthroughs, inspections, and static analysis tools (e.g., SonarQube).
Purpose: Detects errors in syntax, logic, or standards compliance before runtime.
Benefits
Identifies issues early, reducing development costs.
Improves code quality and adherence to standards.
Saves time by addressing defects before execution.
What is Dynamic Testing?
Dynamic testing evaluates software by executing it in a runtime environment. It tests the system’s functionality, performance, and behaviour under various conditions.
Key Characteristics
Execution-Based: Runs the software to validate its behaviour.
Techniques: Unit testing, integration testing, system testing, and user acceptance testing.
Purpose: Ensures the software meets functional and non-functional requirements.
Benefits
Validates real-world performance and user experience.
Detects runtime issues like crashes or performance bottlenecks
