Types of Testing - Page 2

Performance testing - Validates that both the online response time and batch run times meet the defined performance requirements.

Usability testing - testing for 'user-friendliness'. Clearly this is subjective, and will depend on the targeted end-user or customer. User interviews, surveys, video recording of user sessions, and other techniques can be used. Programmers and testers are usually not appropriate as usability testers.

Install/uninstall testing - testing of full, partial, or upgrade install/uninstall processes.

Recovery testing - testing how well a system recovers from crashes, hardware failures, or other catastrophic problems.

Security testing - testing how well the system protects against unauthorized internal or external access, willful damage, etc; may require sophisticated testing techniques.

Compatibility testing - testing how well software performs in a particular hardware/software/ operating system/network/etc. environment.

Exploratory testing - often taken to mean a creative, informal software test that is not based on formal test plans or test cases; testers may be learning the software as they test it.

Ad-hoc testing - similar to exploratory testing, but often taken to mean that the testers have significant understanding of the software before testing it.

Monkey testing:-monkey testing is a testing that runs with no specific test in mind. The monkey in this case is the producer of any input data (whether that be file data, or input device data).
Keep pressing some keys randomely and check whether the software fails or not.

User acceptance testing - determining if software is satisfactory to an end-user or customer.

Comparison testing - comparing software weaknesses and strengths to competing products.

Alpha testing - testing of an application when development is nearing completion; minor design changes may still be made as a result of such testing. Typically done by users within the development team.

Beta testing - testing when development and testing are essentially completed and final bugs and problems need to be found before final release. Typically done by end-users or others, not by programmers or testers.

Mutation testing - a method for determining if a set of test data or test cases is useful, by deliberately introducing various code changes ('bugs') and retesting with the original test data/cases to determine if the 'bugs' are detected. Proper implementation requires large computational resources

Cross browser testing - application tested with different browser for usablity testing & compatiblity testing

Concurrent testing - Multi-user testing geared towards determining the effects of accessing the same application code, module or database records. Identifies and measures the level of locking, deadlocking and use of single-threaded code and locking semaphores etc.

Negative testing - Testing the application for fail conditions,negative testing is testing the tool with improper inputs.for example entering the special characters for phone number
