State transition testing , Decision Table testing


State transition testing:-  If we pass different input variables to check multiple states that are called state transition testing.
When we log in with a valid pin code in ATM then it will process to transaction menu otherwise it will provide a try again message and provide re-enter pin code, it is an example of state transition where the state of the machine will be changed according to input data.
Decision Table Testing:-   Using this we can check software using different input conditions. It will return true condition and false condition results, it can also provide branching and nesting.
If we create the greatest number program using three different numbers then it is part of decision table testing.
IT is the best way to perform testing operations.
