Snapshot of Software Performance Testing
How is software performance testing defined? performance testing is a process, not a single, one time test. The process determines the speed and effectiveness of a software program, a computer or other device, or network. Software performance testing verifies that some automated function, or device, does indeed, perform according to the specifications that a manufacturer prints on the box or guarantee card. At the heart of the process is a comparison of the parameters of two or more programs. The parameters could be data transfer rate, throughput, reliability, speed, bandwidth, or, efficiency, or others related to security and integrity. Sometimes
One example of performance testing would be as a diagnostic aid in load testing - checking to see how fast a web page loads when it has a large number of users. Load testing is a quantitative test done in a lab, and it measures the number of MIPS (millions of instructions per second) at which a system functions. Simply put, it measures the response time of the system.
Performance testing impacts business metrics. What is the impact of slow pages on a business that uses 'software as a service', such as Live.com? This is done as described above, in load testing, with split testing. The tester will separate the users into two categories: half will get the normal page, and the other half gets the same page, but artificially slowed. The effects are immediate - people who get a slow page click away from the page and the business metrics are visible. When this is done, businesses can see for themselves just how valuable load testing, split testing and many other tools in software performance testing
Software testing is always planned and prepared in advance and performed systematically. Stages are built into the plan. Tests case design techniques and test approaches are identified and deployed by teams during the software engineering procedure. Some testing strategies have been templated and have the following hallmarks:
• As a rule, Testing begins with a module, or block of code, and works upwards, building with the purpose of integration of the complete system. Debugging must be included in any testing strategy, even though they are seemingly different activities.
• As a practice, after testing is conducted by the software developer, an independent test group conducts another test.
• Since there is no one testing technique, and they all have different applicability, many different kinds of tests are conducted diverse points in during the development cycle.
