WHY IS PERFORMANCE CRITICAL AT ALL LEVELS OF BUSINESS

PERFORMANCE TESTING

Performance testing is the practice of evaluating how a system performs in terms of responsiveness and stability under a particular workload. Performance tests are typically executed to examine speed, robustness, reliability, and application size.

WHY PERFORMANCE TESTING

– To determine whether the application satisfies performance requirements (for instance, the system should handle up to 1,000 concurrent users).

– To locate computing bottlenecks within an application.

– To establish whether the performance levels claimed by a software vendor are indeed true.

– To compare two or more systems and identify the one that performs best.

– To measure stability under peak traffic events.

Different types of performance tests

Load Testing: Load Testing is executed to identify the maximum operating capacity of an application. It helps in identifying the performance of an application when it is used simultaneously by multiple users.

Stress Testing  This is a process that is used to test the durability of an application or software. It is done by testing it beyond the limit of how it can normally perform.

Spike testing: This test is performed to determine the weakness of an application. It helps in understanding the performance of the system under the sudden increase or decrease of the user load.

Endurance testing: This is also known as Soak testing. In endurance testing, a system is tested with a certain load extended over a certain period of time to determine the performance of the system under continuous use.

Volume Testing : It is a process to identify the performance of the system by increasing the volume of data in the database

USAGES AND NEEDS:

Performance testing is critical to customer satisfaction; if your application’s performance doesn’t meet the expectations of your customers, they will move on to your competitor. Performance testing can be complicated and requires specialized test planning. To plan a comprehensive test strategy, it is important to fully understand the challenges of performance testing as well as the process and tools available to create an effective performance test.

Performance Testing can be used in Cloud Applications, Desktop Applications, Mobile Application.

Here is the Performance Testing in Mobile applications:

• Experts believe that mobile application errors are much higher than what have been reported. Mobile applications struggle with network issues, especially when the server is congested. And if the applications are running on unreliable mobile networks, it becomes even more difficult
• Poor application experience means frustrated customers, which translates into lost revenues. Research shows that over 47% of the respondents, when faced with a broken image would exit the application and transact on a different platform.
• Application speed changes as per regions. It is important to update an app country-wise and test it for the same. Internal testing should be done on the performance of the applications in various speeds and on different networks. Some countries have 2G connections, some have 3G and others 4G. It is important to check whether users of the application across the world can use it conveniently, without any network issues.
• Moreover, a system may run conveniently with concurrent users. Performance testing determines whether high speed, scalability, and stability of the system is achieved by the system under high demand.

TOOLS OF PERFORMANCE TESTING

• JMeter

JMeter is an open source tool that can be used for performance and load testing for analyzing and measuring the performance of a variety of services. This tool is mainly used for web and web service applications
