Adhoc testing is a testing approach; it is the least formal
testing approach

without follow the test cases.

Ad hoc testing is concern with the Application Testing 
without following any rules or test cases. For Ad hoc 
testing one should have strong knowledge about the 
Application

Ad hoc testing is a subset of Monkey testing.In this no
formal test cases are used,it is being done due to lack of
the time. No testing approach is being used in this.

Adhoc testing : without test data r any documents 
performing testing.

Adhoc Testing : Testing the application by tester who is 
having minimum knowledge of application information.so that 
his approach would be different to usual,there is chances 
of discovering uncovered bugs

AdHoc means doing something which is not planned.

Adhoc testing has advantage as well as disadvantage for 
every project

advantage: we check the application randomly so we reduce 
time consuming

Disadvantage: we will check the application randomly so we 
miss some activities. so there is chance of bugs i that 
activity

adhoc is unstructured and inconsistent level of testing.

Ad - Hoc testing: This testing is done by developer or 
tester by excecuting the sample log of the application.This 
testing done to familarise with application and understand 
the application.

Due to lack of time, resources and budget..,the Testing 
Team is not able to conduct optimal testing.so they are 
conducting testing  on main activities of that build only.

if no proper documents are provided to testing team 
then they try to understands the requirements then 
continuos the testing without any proper methodology

Ad Hoc Testing:- The testing without using any test cases 
is called Ad Hoc testing.in this testing tester's attitude 
should be "Test to Break".It should test all the major 
functionality it's called Ad Hoc Testing.
   Thank You.

Ad hoc testing is a subset of blackbox testing

Adhoc Testing is an unstructured testing that is performed
without Planning and Documentation.

The term adhoc means "for this" (something intended for a 
particular situation or purpose). Testing is performed 
without planning and Documentation

"ADHOC"  testing is a type of testing ,In which one will
perform testing on the application in his own way after
understanding the requirements clerly.

"ADHOc" testing is a type of testing ,in which one will
perform testing on the application in his own way after 
understanding the requirements clearly....

Adhoc testing is a type of testing that is completely
informal and this is done using no recognized test case design.
This is done purely based on the knowledge of the tester in
the application.

its a type of testing in which one perform the tg there own 
style ofter understanding the reqirements usaly it is done 
by the testers
