Exploratory testing is a powerful and fun approach to testing. The plainest and simplest definition of exploratory testing is test design and test execution at the same time. Exploratory testing is opposite of scripted testing which have predefined test procedures, whether manual or automated. Exploratory test are not defined in advance. In this type of testing the testers have to do minimum effort for planning but maximum execution cover so that tester gets exact functionality of application. This can be helpful for tester to decide what can be next to test. During testing the tester learns about behavior of the software application, start creating test plan or test scenarios.
Advantages of exploratory testing:
- Less preparation is needed, important bugs are found quickly, and at execution time, the approach tends to be more intellectually stimulating than execution of scripted tests.
- Testers can use deductive reasoning based on the results of previous results to guide their future testing on the fly. They do not have to complete a current series of scripted tests before focusing in on or moving on to exploring a more target rich environment. This also accelerates bug detection when used intelligently.
- After initial testing, most bugs are discovered by some sort of exploratory testing. This can be demonstrated logically by stating, “Programs that pass certain tests tend to continue to pass the same tests and are more likely to fail other tests or scenarios that are yet to be explored.”Manual Testing
