Ad-hoc and Exploratory Testing

Ad-hoc Testing

Ad-hoc testing is informal, unplanned testing performed without documented test cases, relying on the tester's intuition and experience to find defects.

Exploratory Testing

Exploratory testing is a more structured variant where the tester simultaneously learns the application, designs tests, and executes them, often using time-boxed sessions called "test charters."

Key Differences

• Ad-hoc testing has no structure or documentation, while exploratory testing follows a lightweight, guided structure.
• Exploratory testing is often used to supplement scripted testing, uncovering issues that formal test cases might miss.
• Both rely heavily on the tester's domain knowledge and creativity.
