Software Testing Methodologies 

A Detailed Overview

What is Software Testing Methodology?

Strategies designed to find and fix errors in an application, ensure its functionality and appearance, and verifies that it behaves as specified.

Types of Software Testing Methodologies

Functional Testing: Check software functionality to ensure all features work as expected. Non-Functional Testing: Check critical aspects of software like performance, usability, reliability, etc.

Methods of Functional Testing

Tests small chunks of code that can be logically isolated within a system. This reduces errors, bad code, and makes the code clean and ready for documentation.

1. Unit Testing

Combines individual software modules and tested them as a group to determine whether the system complies with specified functional requirements.

2. Integration Testing

Analyzes the compliance of an integrated software product with its specifications. The goal is to identify and fix bugs before the final rollout.

3. System Testing

Assess whether the system complies with the business/user requirements and whether it is suitable for delivery. Testing is divided into two stages; Alpha and Beta.

4. Acceptance Testing

Methods of Non-Functional Testing

Checks the application performance by putting it through intensive loads until breakage starts to occur. Performance testing involves stress, load, and scalability tests.

5. Performance Testing

Check for bugs/issues before the product goes into production to secure it against potential threats, vulnerabilities, or any risks.

6. Security Testing

Checks how the application's user interface looks and feels when it is used by real users. It exposes any usability defect.

7. Usability Testing

Test the application's compatibility with other operating systems, devices, hardware, and more. But, it brings all the security risks related to a third party.

8. Compatibility Testing
