Question 1

What is the primary goal of integration testing?

Accepted Answer

Verifying that combined components or modules work correctly together

Answer

Question 2

Which tool category is commonly used for automated UI testing of web applications?

Accepted Answer

Browser automation tools such as Selenium or Playwright

Accepted Answer

Input values at the edges of valid ranges

Answer

Boundary value analysis tests input at the exact minimum and maximum edges of valid ranges, where defects most frequently occur.

Question 5
