Software Testing

Software testing is the process of evaluating a software application to verify that it works as expected and meets specified requirements. It helps identify defects, errors, and missing functionalities before the software is delivered to users.
Types of Software Testing
Manual Testing
Manual testing is a software testing technique in which testers execute test cases manually without using automation tools. It helps verify application functionality and identify defects by comparing actual results with expected results.
Example: A tester manually checks whether a login page accepts valid credentials.
Automation Testing
Automation testing is a software testing technique in which test cases are executed using scripts and automation tools. It helps automate repetitive tasks, improving testing speed, accuracy, and efficiency.
Example: A Selenium script automatically tests the login functionality and verifies the result.
Test Case
A Test Case is a detailed document that specifies the steps, input data, execution conditions, and expected results used to verify whether a particular feature of an application works correctly. It ensures that the software meets the specified requirements.
Test Scenario
A Test Scenario is a high-level description of a functionality or feature that needs to be tested. It focuses on what to test in the application without providing detailed steps.
