Ad hoc and exploratory testing are informal software testing techniques used to quickly identify defects without strict documentation or formal test cases. Both approaches focus on discovering unexpected issues by actively interacting with the application.
- Helps find defects quickly with minimal planning
- Used when time is limited or formal test cases are not available
- Focuses on real-time testing of the application behavior
Ad hoc Testing
Adhoc testing is an informal and unstructured software testing technique where testing is performed without any planning, documentation, or predefined test cases. It is mainly done to quickly find defects by randomly checking the application.
Example: A tester randomly clicks buttons in a shopping app (add to cart, checkout, profile) without test cases to quickly find unexpected crashes or errors.
Exploratory Testing
Exploratory testing is an informal testing approach where learning, test design, and test execution happen at the same time. Testers explore the application actively and create test cases on the spot based on their understanding.
Example: Testing a login page by trying valid/invalid inputs, checking errors, and exploring system behavior in real time while learning the feature.
Adhoc Testing Vs Exploratory Testing
| Ad hoc Testing | Exploratory Testing |
|---|---|
| Random, unplanned testing without test cases | Simultaneous learning, test design, and execution |
| No prior planning or structure | Semi-structured and goal-based approach |
| No documentation | Light documentation may be done |
| Completely random actions | Guided exploration based on understanding |
| Focus on quick defect detection | Focus on learning + defect detection |
| Relies on tester’s intuition | Relies on experience, knowledge, and exploration |
| No specific goals | May have test goals or charters |
| Used when time is very limited | Used to explore and understand application deeply |
