• One-time tests
  
• Frequently changing UI
  

Q34. What is CI/CD in Agile?

Continuous Integration and Continuous Deployment for faster releases.

Q35. Role of testing in CI/CD?

Automation acts as a quality gate before deployment.

Q36. What is API testing in Agile?

Testing backend services early, even before UI is ready.

Q37. Why is API testing critical in Agile?

• Faster execution
  
• Stable testing
  
• Early defect detection
  

Q38. What do you validate in API testing?

• Status codes
  
• Response body
  
• Error handling
  

Q39. Sample API validation scenario

Story: Create order

• Validate HTTP 201
  
• Verify order ID
  
• Check DB entry
  

Q40. How is SQL used in Agile testing?

To validate backend data consistency.

Q41. Example SQL query

SELECT status FROM orders WHERE order_id = 123;

Q42. What is flaky test in Agile?

Tests that pass/fail intermittently due to timing or environment.

Q43. How do you handle flaky tests?

Stabilize waits, clean data, improve environment reliability.

Q44. What is exploratory testing in Agile?

Unscripted testing within sprint to discover hidden issues.

Q45. Why is exploratory testing important in Agile?

Agile changes frequently; exploratory testing adapts quickly.

Q46. What is TDD?

Test-Driven Development – tests written before code.

Q47. What is BDD?

Behavior-Driven Development – focuses on business behavior.
