Question: What is black-box (or functional) testing?
Answer: Black Box Testing is testing without knowledge of the internal workings of the item being tested. The Outside world comes into contact with the test items, --only through the application interface ,,, an internal module interface, or the INPUT/OUTPUT description of a batch process. They check whether interface definitions are adhered to in all situation and whether the product conform to all fixed requirements. Test cases are created based on the task descriptions.

Question: What is the Automated Testing?
Answer: Automated testing is as simple as removing the "human factor" and letting the computer do the thinking. This can be done with integrated debug tests, to much more intricate processes. The idea of the these tests is to find bugs that are often very challenging or time intensive for human testers to find. This sort of testing can save many man hours and can be more "efficient" in some cases. But it will cost more to ask a developer to write more lines of code into the game (or an external tool) th Source: CoolInterview.com
Question: What is Online Help Test?
Answer: Online help tests check the accuracy of help contents, correctness of features in the help system, and functionality of the help system.
Question: Explain Boundary Test?
Answer: Boundary tests are designed to check a program's response to extreme input values. Extreme output values are generated by the input values. It is important to check that a program handles input values and output results correctly at the lower and upper boundaries. Keep in mind that you can create extreme boundary results from non-extreme input values. It is essential to analyze how to generate extremes of both types. In addition. sometime you know that there is an intermediate variable invol Source: CoolInterview.com
Question: How to Install/uninstall Test?
Answer: Web system often require both client-side and server-side installs. Testing of the installer checks that installed features function properly--including icons, support documentation , the README file, and registry keys. The test verifies that the correct directories are created and that the correct system files are copied to the appropriate directories. The test also confirms that various error conditions are detected and handled gracefully.
Testing of the uninstaller checks that the inst Source: CoolInterview.com
Question: Explain Regression Testing Technique?
Answer: Background " One segment of system is developed and thoroughly tested.
" Another segment is changed which has disastrous effect on the tested segment.
" The implemented change, new data or parameters have created change in the already tested segment.
Usage " All aspects of system remain functional after testing.
" Change in one segment does not change the functionality of other segment.
Objectives " Determine -
system documents remain current

Question: What is the Regression testing?
Answer: Did a new build break an existing function? Repeat testing after changes for managing risk relate to product enhancement.
A regression test is performded when the tester wishes to see the progress of the testing processs by performing identical tests before and after a bug has been fixed. A regression test allows the tester to compare expeted test results with the actual results.
Regression testing's primary objective is to ensure that all bugfree features stay that way. In add Source: CoolInterview.com
Question: Explain Testing Methods?

Question: What is Forced-Error Test?
Answer: The forced-error test (FET) consists of negative test cases that are designed to force a program into error conditions. A list of all error messages thatthe program issues should be generated. The list is used as a baseline for developing test cases. An attempt is made to generate each error message in the list. Obviously, test to validate error-handling schemes cannot be performed until all the handling and error message have been coded. However, FETs should be thought through as early as possi Source: CoolInterview.com

Question: What is Click-stream measurement tests?
Answer: Makes a request for a set of Web pages and records statiestics about the response, including total page views per hour, total hits per week, total user sessions per week, and derivatives of these numbers. The downside is that if your Web-enabled application takes twics as many pages as it should for a user to complete his or her goal, the click stream test makes it look as though your Web site is popular, while to the user your Web site is frustrating.

Question: What is External Beta Testing?
Answer: External beta testing offers developers their first glimpse at how users may actually interact with a program. Copies of the program or a test URL, sometimes accompanied with letter of instruction, are sent out to a group of volunteers who try out the program and respond to questions in the letter. Beta testing is black-box, real-world testing. Beta testing can be difficult to manage, and the feedback that it generates normally comes too late in the development process to contribute to improved Source: CoolInterview.com
