Static Testing

What is Static Testing?

Static Testing, a software testing technique in which the software is tested without executing the code. It has two parts as listed below:

• Review - Typically used to find and eliminate errors or ambiguities in documents such as requirements, design, test cases, etc.

• Static analysis - The code written by developers are analysed (usually by tools) for structural defects that may lead to defects.

Types of Reviews:

The types of reviews can be given by a simple diagram:

Static Analysis - By Tools:

Following are the types of defects found by the tools during static analysis:

• A variable with an undefined value

• Inconsistent interface between modules and components

• Variables that are declared but never used

• Unreachable code (or) Dead Code

• Programming standards violations

• Security vulnerabilities

• Syntax violations
