Load Testing and Performance Testing are commonly said as positive testing where as Stress Testing is said to be as negative testing. Say for example there is a application which can handle 25 simultaneous user logins at a time. In load testing we will test the application for 25 users and check how application is working in this stage, in performance testing we will concentrate on the time taken to perform the operation. Where as in stress testing we will test with more users than 25 and the test will continue to any number and we will check where the application is cracking the Hardware resources.
It is an alternative form of Testing, where some colleagues were invited to examine your work products for defects and improvement opportunities. Some Peer review approaches are, Inspection – It is a more systematic and rigorous type of peer review. Inspections are more effective at finding defects than are informal reviews.Ex : In Motorola’s Iridium project nearly 80% of the defects were detected through inspections where only 60% of the defects were detected through informal reviews. Team Reviews – It is a planned and structured approach but less formal and less rigorous comparing to Inspections. Walkthrough – It is an informal review because the work product’s author describes it to some colleagues and asks for suggestions. Walkthroughs are informal because they typically do not follow a defined procedure, do not specify exit criteria, require no management reporting, and generate no metrics. Pair Programming – In Pair Programming, two developers work together on the same program at...
