Load testing is a software testing technique used to examine the behavior of the system when subject to expected and extreme normal load conditions. Load testing are generally carried out under controlled laboratory conditions to differentiate between two different systems. Load testing are designed to test the requirements of non-application software applications. Load testing are sometimes referred to as longevity testing or endurance testing.
Stress testing is a type of performance testing to check the stability of the software when there is not enough hardware resources such as CPU, memory, disk space etc. Stress testing is a negative testing where we load software with a large number of concurrent users / processes that can not be handled by hardware system resources. This testing is also known as Fatigue testing, this test should capture application stability by testing it exceeds its bandwidth capacity.
The main idea behind the stress test is to determine the system failure and to observe how the system gracefully recovers, this quality is known as repeatability. The pressure test comes under the Non-Functional Test & it’s designed to test the requirements of non-application software applications. This test will run under a controlled environment before it is launched, so that we can appropriately capture the behavior of the system under the most uncertain scenario.
Endurance testing is a type of test that does non functional. Endurance testing involves testing systems with expected amount of loads in the long run to look for system behavior. Let’s take an example where the system is designed to work for 2 hours but the same system lasts for 5 hours of time to check the endurance of the system. Test cases are usually carried out to examine system behavior such as memory leak or failed system or random behavior. Sometimes endurance testing is also referred to as a Soak testing.
Scalability testing is a non-functional testing type and is a software application testing to determine its ability to improve in terms of non-functional capabilities such as supported user loads, transaction numbers, data volumes etc. The main goal if this testing is to understand where the system peaks prevent invasion.
Volume testing is a non-functional test that refers to testing software applications with a large amount of data to be processed to check for application efficiency. The main goal of the testing is to monitor application performance under different database volumes.
