Static Testing VS Dynamic Testing

This comprehensive hands-on article covers the details of Static and Dynamic testing and their differences.

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 Defects early in STLC. It examines work documents and provides review comments.

Dynamic Testing

Under Dynamic Testing, the code is executed. It checks for functional behavior of the 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.

Difference Between Static Testing and Dynamic Testing

Point1

Static Testing: Testing was done without executing the program

Dynamic Testing: Testing is done by executing the program

Point2

Static Testing: This testing does the verification process

Dynamic Testing: Dynamic testing does the validation process

Point3

Static Testing: Static testing is about the prevention of defects

Dynamic Testing: Dynamic testing is about finding and fixing the defects

Point4

Static Testing: Static testing gives an assessment of code and documentation

Dynamic Testing: Dynamic testing gives bugs/bottlenecks in the software system.

Point5

Static Testing: Static testing involves a checklist and process to be followed

Dynamic Testing: Dynamic testing involves test cases for execution

Point6

Static Testing: This testing can be performed before the compilation

Dynamic Testing: Dynamic testing is performed after compilation

Point7

Static Testing: Static testing covers the structural and statement coverage testing

Dynamic Testing: Dynamic testing covers the executable file of the code

Point8

Static Testing: The cost of finding defects and fixing them is less

Dynamic Testing: The cost of finding and fixing defects is high

Point9

Static Testing: Return on investment will be high as this process involved an early stage

Dynamic Testing: Return on investment will be low as this process involves after the development phase

Point10

Static Testing: More reviews and comments are highly recommended for good quality

Dynamic Testing: More defects are highly recommended for good quality.

Point11

Static Testing: Requires loads of meetings

Dynamic Testing: Comparatively requires lesser meetings
