Software Testing Full Course (Detailed Guide)

Introduction to Software Testing

Software Testing is a process used to identify the correctness, completeness, and quality of developed software. It involves executing software/system components using manual or automated tools to evaluate one or more properties of interest. The goal is to find software bugs or errors and ensure that the software behaves as expected.

Importance of Software Testing:

Ensures product quality.

Enhances user experience.

Reduces maintenance costs.

Prevents software failures.

Ensures software performs reliably and meets requirements.

Types of Software Testing

1. Manual Testing:

Manual Testing is the process of manually checking software for defects. The tester takes over the role of an end-user and tests the software to find unexpected behavior.

Sub-types:

Black Box Testing

White Box Testing

Gray Box Testing

2. Automation Testing:

Automation Testing uses tools and scripts to test software automatically. It is useful for regression testing, performance testing, etc.

Popular Tools:

Selenium

QTP (UFT)

TestComplete

Appium

Levels of Software Testing

Unit Testing: Testing individual units/components of a software.

Integration Testing: Testing the integration of modules.

System Testing: Testing the complete system as a whole.

Acceptance Testing: Testing software in the real-world scenario to verify it meets all requirements.
