1. What is AI in Software Testing?

Answer:
AI in software testing refers to the use of Artificial Intelligence and Machine Learning techniques to improve testing activities such as test case generation, defect prediction, test maintenance, test optimization, visual validation, and intelligent automation.

AI helps QA teams:

Reduce repetitive manual work
Improve test coverage
Detect flaky tests
Predict high-risk areas
Generate intelligent test data
Speed up regression testing

2. What is the difference between Traditional Automation and AI-based Automation?

Traditional Automation	AI-based Automation
Rule-based	Learns from data
Hardcoded locators	Self-healing locators
Requires frequent maintenance	Adaptive maintenance
Static scripts	Intelligent execution
Breaks easily on UI changes	Handles dynamic changes

Example:
In Playwright or Selenium, if an XPath changes, traditional automation fails. AI-based tools can identify elements using attributes, text, position, or visual recognition.

3. What are Self-Healing Test Scripts?

Answer:
Self-healing scripts automatically recover from UI changes by identifying alternative locators when the original locator fails.

Example:

If:

id="loginBtn"

changes to:

id="signinBtn"

AI tools analyze:

Text
CSS structure
Neighbor elements
Historical locator data

and automatically update the locator.
