I do not think so, yet many sources say it is.
As I understand it:
Context-driven testing means that when planning testing on our project, I choose the methods, practices, etc. in order to fit the context. I choose the approach
While exploratory testing is a just a method of testing, where testers explore certain part of the application and dynamically design and run test cases,possibly exploring new areas and new tests.
I know Exploratory testing is related to context-driven but I do not believe it means the same.
Is that correct understanding?
