To answer this question, we need to understand the concept of static testing.
Static testing is a software testing technique that involves reviewing and inspecting the software artifacts without executing the program. It is performed during the early stages of the software development life cycle to identify defects, improve quality, and ensure compliance with standards.
Let's go through each option to understand why it is correct or incorrect:
Option A) Code inspection - This option is correct. Code inspection is a static testing technique where the software code is reviewed manually to find defects, improve code quality, and ensure adherence to coding standards. It is a form of static testing because it does not involve executing the code.
Option B) Coverage analysis - This option is incorrect. Coverage analysis is a dynamic testing technique that measures the amount of code covered by test cases. It requires executing the program and analyzing the code coverage achieved.
Option C) Usability assessment - This option is incorrect. Usability assessment involves evaluating the software's user interface and user experience to determine how easy it is to use. It is a form of dynamic testing because it typically involves interacting with the software.
Option D) Installation test - This option is incorrect. Installation test is a type of dynamic testing that verifies the successful installation and configuration of the software. It involves executing the installation process and checking if the software functions correctly.
The correct answer is Option A) code inspection. This option is correct because code inspection is a static testing technique that involves reviewing the software code without executing it.
