What's Scalability and Performance Testing
Scalability and performance testing is the way to understand how the system will handle the load cause by many concurrent users. In a Web environment concurrent use is measured as simply the number of users making requests at the same time.
Performance testing is designed to measure how quickly the program
completes a given task. The primary objective is to determine whether
the processing speed is acceptable in all parts of the program.
If explicit requirements specify program performance, then performance test
are often performed as acceptance tests.
As a rule, performance tests are easy to automate. This makes sense above
all when you want to make a performance comparison of different system
conditions while using the user interface. The capture and automatic replay
of user actions during testing eliminates variations in response times.
This type of test should be designed to verify response and excution time.
Bottlenecks in a system are generally found during this stage of testing.
