What is White box testing/unit testing?
Unit testing – The most ‘micro’ scale of testing; to test particular functions or code modules. Typically done by the programmer and not by testers, as it requires detailed knowledge of the internal program design and code. Not always easily done unless the application has a well-designed architecture with tight code; may require developing test driver modules or test harnesses.
What is Integration testing?
Integration testing – Testing of combined parts of an application to determine if they function together correctly. The ‘parts’ can be code modules, individual applications, client and server applications on a network, etc. This type of testing is especially relevant to client/server and distributed systems.
What is Black box testing?
Black Box testing is also called system testing which is performed by the testers. Here the features and requirements of the product as described in the requirement document are tested.
What knowledge you require to do white box, integration and black box testing?
For white box testing you need to understand the internals of the module like data structures and algorithms and have access to the source code and for black box testing only understanding/functionality of the application.
What is Regression testing?
Regression testing: Re-testing after fixes or modifications of the software or its environment. It can be difficult to determine how much re-testing is needed, especially near the end of the development cycle. Automated testing tools can be especially useful for this type of testing..
Why do we do regression testing?
In any application new functionalities can be added so the application has to be tested to see whether the added functionalities have affected the existing functionalities or not. Here instead of retesting all the existing functionalities baseline scripts created for these can be rerun and tested.
How do we regression testing?
Various automation testing tools can be used to perform regression testing like WinRunner, Rational Robot and Silk Test.
What is Integration testing?
Testing of combined parts of an application to determine if they function together correctly. The ‘parts’ can be code modules, individual applications, client and server applications on a network, etc. This type of testing is especially relevant to client/server and distributed systems.
What is the difference between exception and validation testing?
Validation testing aims to demonstrate that the software functions in a manner that can be reasonably expected by the customer. Testing the software in conformance to the Software Requirements Specifications.
Exception testing deals with handling the exceptions (unexpected events) while the AUT is run. Basically this testing involves how to change the control flow of the AUT when an exception arises.
What is the difference between regression automation tool and performance automation tool?
Regression testing tools capture test and play them back at a later time. The capture and playback feature is fundamental to regression testing.
Performance testing tool determine the load a server can handle. And must have feature to stimulate many users from one machine, scheduling and synchronize different users, able to measure the network load under different number of simulated users.
What are the roles of glass-box and black-box testing tools?
Glass-box testing also called as white-box testing refers to testing, with detailed knowledge of the modules internals. Thus these tools concentrate more on the algorithms, data structures used in development of modules. These tools perform testing on individual modules more likely than the whole application. Black-Box testing tools refer to testing the interface, functionality and performance testing of the system module and the whole system.
