Often juxtaposed with ad hoc testing, exploratory testing is an investigative process where test design and execution occur simultaneously. This approach is distinct from scripted testing, as it does not follow predefined items or plans. Many organisations engage external teams for exploratory testing post-scripted testing to ensure thorough coverage.

The benefits of exploratory testing are extensive. Testers, while guided on focus areas, are encouraged to let their insights flow creatively and intuitively. Their subsequent steps are typically informed by the outcomes of their previous tests. This method is particularly effective when pinpointing elusive issues, as testers must creatively probe and reproduce errors to understand their root causes. Exploratory testing is a crucial strategy employed by skilled testers everywhere.
