What is Ad-hoc Testing and how does it differ from Exploratory Testing?

Ad-hoc Testing is informal testing performed without any planning, documentation, or expected results. It’s random testing to find defects through an unstructured approach.

Characteristics

• No formal process or documentation
• Completely random and unstructured
• No test cases or test design
• Performed when time is limited
• Relies on tester’s intuition
• Usually one-time activity

Types of Ad-hoc Testing

1. Buddy Testing: Developer and tester work together
2. Pair Testing: Two testers work on same feature
3. Monkey Testing: Random inputs without any pattern
