Ad hoc testing is the kind of software testing service that is carried out without specifications and planning. It is executed only unless the defects are uncovered. There is the necessity for adhoc testing when testers are short of time and cannot perform thorough testing so as to involve proper test cases along with test plans.

Adhoc testing is executed after performance of formal testing on the app. Adhoc testing is less formal as it is based on unstructured approach.

From time to time, adhoc testing is necessary when the project is over, after all the test cases are done. Accordingly, in this regard adhoc testing is performed additionally in order to complement other kinds of testing.

Its effectivity depends only on capability of the testers, their in-depth understating about System being tested. Using only own intuition, the tester must detect bugs without following specifications/requirements.

What is advantage of Adhoc testing? Resorting to it, you manage to save much time. Sometimes, it is necessary to spend a lot of precious time for preparation and explanation of tests in order to change a design of the program. There is no need to waste time with Adhoc testing since it does not require specifications or planning.

Steps to Consider

Get prepared well. Learn from other projects about defects. Then, when testing, you will not overlook bugs that must be found.

Make a rough copy. You need just a rough draft without going into details, like while planning. You do not need to write down what, how and when to test.

Test during sessions. Run test of the software or app step by step, which is to say, functionality by functionality. Then it will be easier to concentrate on the problems and understand them, if any.

Aim at key areas. You should target uncovered areas in testing designs or user documents. Be able to use various tools. Some defects are easier to detect with special tools, so they matter much to debuggers and task monitors.

Record found bugs. Make record of your findings, where they were in app. This will help developer and those who will test the apps in future.

Are you unsure of own capabilities? Consult specialists of software testing companies and they do their best to solve your problems.
