AD – HOC Testing ( also called Monkey Testing )

Testing the application randomly is called Ad-hoc testing.

Why we do Ad-hoc testing ?

1)End-users use the application randomly and he may see a defect, but professional TE uses the application systematically so he may not find the same defect. In order to avoid this scenario, TE should go and then test the application randomly (i.e, behave like and end-user and test).

For ex,

In the above figure, after we have tested the application for FT, IT and ST – if we click on some feature instead of going to homepage (or) sometimes datapage, if it goes to blank page then it will be a bug. In order to avoid these kind of scenarios, we do Ad-hoc testing.

2) Development team looks at the requirements and build the product. Testing Team also look at the requirements and do the testing. By this method, Testing Team may not catch many bugs. They think everything works fine. In order to avoid this, we do random testing behaving like end-users.

3) Ad-hoc is a testing where we don’t follow the requirements (we just randomly check the application). Since we don’t follow requirements, we don’t write test cases.
