Some Basic Difference between Load and Performance Testing

As an engineer or developer everyone has to opt for load and performance testing which provides them the assurance that each feature will work smoothly without disrupting the system. It has been seen that tester often get confused between load testing and performance testing as they are unable to differentiate between both of them. Difference between the Load and Performance Testing Here is the primary difference between load and performance testing which will provide you a brief idea about both the testing process: •    Load Testing– Load Testing is a simple testing method where you will test by notching up the load steadily till it reaches its threshold limit. The primary purpose of the load testing is to determine whether the system can handle a large amount of load and work smoothly without shattering. This testing process checks the endurance of the system and monitors the result. Apart from that this checking process also highlights the defects like mismanagements of memory, buffer overflow, and memory leaks. It also helps the developer determine the top limit of application attributes like hardware, network, and database. •    Performance Testing -   Performance testing helps the tester to check the behaviour and performance of the system. The things that are tested in this process are scalability, responsiveness, reliability, resource usage and stability of the software along with the system. Basically, performance testing doesn't provide the defect of the system rather it provides the tester to see whether it meets the accurate benchmark result set the by the industry.

Know In-Depth About Load And Performance Testing For Application Performance

With relate  to  smooth running of your applications, it’s vital to implement load and performance testing. There are 6 types of performance testing. They are: load, spike, isolation, configuration, soak and stress. Load testing is often used to test the performance of the application as it is the best way to understand the behaviour of system/application under expected lead. A peep looks into load and performance testing When load testing is done, the software is installed into the system to measure the response. In fact, it is also used to regulate application behaviour under anticipated and normal load conditions. This testing helps in indicating the maximum operating capability of a system along with the elements that cause degradation. Load and performance testing is accomplished in various ways by the professional software testing community. More often, the testers use it to showcase the expected storage capability by stimulating number of users to get access to application at the same instance. This makes the load testing applicable for its use with multi-users. This testing is often used for server model such as web servers. On the other hand, other types of software systems can also be load tested. Graphic editors and word processors can be urged to read a big document. Load testing should be initiated during the initial stage of the project development and extent all through the deployment process. The major benefit of load and performance testing is that it improves overall performance and speed of the task through recognizing some vital areas.

The benefits of Load and Performance Testing

In the field of software development, performance testing is an integral part, which is done to determine the quality of the product developed, how fast the software functions and loading capability. These elements should be certainly tested and ensured before delivering to the clients. A good performing and loading software is important for smooth running of the business. Here are a few benefits of Load and Performance Testing: •    This performance test will help to determine how fast the system performs under a specific workload •    It helps to validate and verify quality attributes of system like reliability, scalability, resource usage and others •   Performance testing is the subset of performance engineering. This is an emerging computer science practice that strives to build performance into design and architecture of system. This is done prior to onset of coding •    Performance testing further help to demonstrate if the system meets all performance criteria •    It further help compare two systems in order to find which system performs better •    It further measures the parts of systems or the workload that cause to perform badly •   It helps detecting the defects in the performance. This process will help reducing a huge cost involved in fixing the bugs. This is the fact in case of functional testing   With may key highlights to point about performance testing, this is an important task to firmly determine the system behavior under a specific system workloads. These types of testing process are very similar to the black box testing. This testing process can prevent potential loss of customers and clients. It can increase the productivity while preventing the damage to the brand or corporate image.

What Is The Difference Between Load and Performance Testing?

Load Testing may be defined as the process of subjecting a computer, server, network or application to a function level approaching the limits of its specifications. Load Testing is a part of Performance Testing. It can be conducted in two different ways. It gives a clear idea to the user the total number of applications that can be run parallel while maintaining the rated level of performance. Examples of this type of testing are follows: 1)    Downloading voluminous amount of files from the internet. 2)    Running various applications on a server simultaneously. 3)    Writing and reading information from a hard disk. 4)    Projecting a server to a huge amount of email traffic. Simplified definition of Load and Performance Testing Performance Testing: What is the speed of the system? Load Testing: How much amount of data can the system process? Performance Testing is performed to measure the speed of components of a particular system in a particular situation. This process includes: Load Testing, Stress Testing, Volume Testing, Endurance Testing, Spike Testing etc. So the relation between Load and Performance Testing is Load Testing is a subset of Performance Testing. The primary aim of Load Testing is to identify the upper limit of the system in terms of various computer peripherals, data base and network. The main goal of Performance Testing is to detect the benchmark behaviour of a system under test. It only measures the quality attributes of the system like scalability, reliability and resource usage.  There are many tools used for performance testing: Jmeter, Open STA, Load Runner, Web Load etc. The attributes of Performance Testing are: Speed, Scalability, Stability, and Reliability

An Excellent Guide About Load And Performance Testing

When you consider the Load and Performance Testing, first you have to ensure what is load testing and performance testing. A load testing is the process of placing demand on the software system and measuring its response. This type of testing is operated to decide the behaviour of a system under both anticipated and normal peak load conditions. Performance testing is a process of regulating effectiveness or speed of a device, software program, network or computer. This procedure can incorporate quantitative tests which are performed in a lab, like measuring the response time at which the system functions. Best practices for Load and Performance Testing The best practices for site performance testing have been designed over time. The following are various efficient approaches to Load and Performance Testing: - 1.    Test from real user geographical locations. Decide the geographical locations of top markets and develop load test cases particular to these locations, keeping in mind third-party CDNs, ISPs, browsers, user devices connection speeds and content providers 2.    You have to test before any kind of anticipated intensify the traffic, anticipate events which produce more traffic for the site like regional or product launches, and perform Load And Performance Testing before these events happen. Web performance testing permits any performance problems to surface and be corrected before the important peaks and events loads happen. 3.    Test frequently and early. The frequent and regular performance and load testing allow the probable issues to be caught before they have a chance to escalate.
