Performance Testing: What, Why, Types

Overall performance testing gathers all the tests that verify an application's speed, robustness, stability, and correct sizing. That examines several indicators such as a browser, site and network the rates of response, server problem processing time, number of acceptable concurrent users architected, CPU memory consumption, and number/type of errors which may be encountered when using a software.

Why should you test the performance of your system?

In short, to ensure that it will meet the service levels expected in production, as well as produce a positive user experience. Application performance is a key determinant of usage, success, and productivity.

Because it can be cost prohibitive to solve a production performance problem, ongoing performance testing strategy search engine optimization is the key to the success of an efficient digital strategy.

What are different types of performance testing?

There are various sorts of performance tests; the main include Load, Unit, Pressure, Soak, and Spike screening.

Load Testing

Used to simulate the number of virtual users using an application. To reproduce practical use and load conditions, depending on response times, this test can be used to identify potential bottlenecks. It also helps the user fine-tune the application architecture's sizing

Product Testing

Simulates transactional process of functional test plan. The aim is to isolate the transactions that could disrupt the program.

Stress Testing

Executed to determine how systems behave in the face of maximum peak activity. To this end, the number of users increases significantly/steadily during the test period.

Soak Testing

Stress tests and Soak tests are meant to improve the number of users to monitor system behavior but over a longer period. The goal is to observe if the dense and ongoing activity, over time, exhibits performance degradation and excessive system resource demand.

What do performance checks measure?

Performance test may be used to examine various success factors such as response times or perhaps the error potential. With these performance results in-hand, you can confidently identify bottlenecks, bugs, and errors; choose to optimize the program to reduce the issue(s).

Why should you perform performance tests?

Be it web or mobile, the lifecycle of an application is made up of two main stages: development and deployment. In each instance, the businesses teams expose the app to end-users on the production architecture.

Development performance testing focuses on components (web services, microservices, APIs). The earlier an application's components are tested, the faster an anomaly will be detected, and the lower expense of quality.

As the application is assembled, performance tests are increasingly extensive. In some cases, performance tests can be carried out during the production, for occasion, when it is difficult/expensive to replicate a creation environment in the development laboratory.

Why automate performance testing? For more flexibility!

Digital transformation is driving a car organizations to accelerate the pace associated with the design of new services, applications or features in the name of gaining/maintaining their competitive advantages. Souple development methodologies provide a solution in this situation.

Despite ongoing industry re-homing of Agile and DevOps, performance testing is a highly-manual process. The purpose of every performance tester is not to let it logjam their Agile development. The solution - integrating as much automation in the performance testing process as is possible.

Having complete automation of your performance testing is possible when testing components. However, a persons intervention of performance technicians is still necessary when performing complex tests on assembled applications.

The future of performance testing is based on the automation of tests across all stages of the software lifecycle.
