Volume Testing
Volume Testing, as its name implies, is testing that purposely subjects a system (both hardware and software) to a series of tests where the volume of data being processed is the subject of the test. Such systems can be transactions processing systems capturing real time sales or could be database updates and or data retrieval.
Volume testing will seek to verify the physical and logical limits to a system's capacity and ascertain whether such limits are acceptable to meet the projected capacity of the organisation's business processing.
Load / Systems Loading
The 'load' on a system refers to the demands placed upon it. The overall load combines many factors and includes :-
Total storage capacity for programs and data
- Number of applications being run concurrently
- Number of concurrent users, peaks, troughs and average
- Number of peripherals: e.g. using a file server as a print server increases demand, as each printed document is 'spooled' to the server's disk before being queued to the printer.
Whilst the sizing of hardware can become complex, once the above points are clear, other factors, such as expected response times / performance can be considered.
.
Stress Testing
Stress Testing is a form of testing which purposely attempts to identify the weakest link of a system. Stress testing will seek to verify that, following any abnormal conditions, the system can revert quickly to normal operation. Such conditions might include : data processing immediately after system downtime, after a network failure, or during peak activity periods.
Performance testing
Performance testing answers the question: How much can you get out of a given product? At VeriTest, we'll take the product you care about—whether it's one you make or one you're considering installing in your line of business—and push it to its limits. This knowledge is valuable at many points in the product life cycle, from development to marketing to technical support. Knowing how a product really performs also gives you the confidence necessary to install a third-party product in a mission-critical environment.
The first step in the performance testing process is determining what factors matter most to you: the number of transactions per second? The speed at which the product it can execute a list of tasks? The number of hours a battery lasts?
Next we determine the best way to measure those factors. Sometimes we'll use a benchmark tool, either from the industry-standard PC Magazine benchmarks that we develop here at VeriTest, or from one of the other test tools we regularly use, such as RadView's WebLoad. Sometimes it may be as simple as a using a stopwatch—physical or in software—to clock performance. More often than not, each performance test—even if it involves a standard test tool—requires a unique methodology, and this is where our years of experience in all sorts of performance measurement and test plan creation give us a big advantage over other testing labs.
Many performance tests also require an underlying testbed, which can be as simple as a single PC or as complex as hundreds of network clients and servers connected over a gigabit backbone with active network monitors. Whatever the appropriate testbed, we're likely to have it—and to have the experience to use it to best effect.
To get accurate performance results, you need testers with the right expertise and the right equipment. With years of experience in performance testing and in creating industry standards for performance measurement tools, VeriTest will take your product—and your profits—to the limit.
