Load Test

Load Test2020-03-15T11:44:50+03:00

Load testing allows application performance to be scaled in response time, resource usage level, hardware capacity, network capacity when the user load is at maximum. Thus, the conditions under which the access to the application is sustainable and how many users can access the application simultaneously are determined. The load test identifies problems such as system delays and page prevention when multiple users access the application, enabling the detection and prevention of potential failures in the system.

The purpose of the load test is to maintain system reliability and performance, ensure the successful operation of the system software, and ensure that the end user can take full advantage of the system.

The load test provides information in the following areas:

  • Response time for each process,

  • Performance of system components under various loads,
  • Network latency between client and server,
  • Software design problems,
  • Server configuration problems, such as Web server, application server, database server,
  • Detecting hardware limitation problems such as memory congestion, network congestion, and determining if the system needs fine tuning or if hardware and software changes are required to improve performance

LOAD TEST STAGES

  • Determining a test scenario
  • Determination of load test operations
  • Preparing data for each process
  • Estimating the number of users accessing the system
  • Determination of connection speeds
  • Identification of different browser and operating systems used
  • Configuration of all servers
  • Test scenario execution and monitoring
  • Collecting and analyzing test results
  • Making recommendations for correction
  • Re-test

STRESS TEST

The stress test is designed to prepare for unexpected situations, to determine how far a particular system can be pushed, and to increase the number of simultaneous requests of a system, even at a complete failure point, to investigate the external limits of performance capacity. If a load test reaches a peak in the number of simultaneous users, the basic load will continue to increase the load in the system until the resources are overloaded. This is to intentionally push the system into a failure state to see how the system handles itself and whether the system can perform a proper recovery. Thus, it enables the analysis of risks at break points and minimizes the risks by fine-tuning.

Frequently Asked Questions About Load Test

Why Should I Have Load Test?2020-03-15T11:42:05+03:00

The purpose of a load test is to prove that the expected volume of a system can handle with a minimum acceptable performance drop. If a load test reaches a peak in the number of simultaneous users, the basic load will continue to increase the load in the system until the resources are overloaded. This pushes the system into a possible failure state to see how the system handles itself and whether the system can perform a proper recovery.

To summarize in short items;

  • The load test tests the reliability and performance of the system.
  • The Load Test helps identify bottlenecks in the system under severe user stress scenarios before they take place in the production environment.
  • The load test provides excellent protection against underperformance and provides complementary strategies for performance management and production environment monitoring.
What Strategies are Used in Load Testing?2020-03-15T11:41:50+03:00

There are many ways to perform a load test. Here are some examples for you to get an idea:

Manual Load Test: This is one of the strategies of carrying out the load test, but it does not produce reproducible results, provides measurable stress levels in an application, and is a process that is very difficult to coordinate.

Load Testing Tools Developed at Home: An organization that recognizes the importance of load testing can create its own tools for performing load tests.

Open Source Load Testing Tools: There are several load testing tools available free of charge as open source. They may not be as sophisticated as their paid colleagues, but they are the best choice if you have a limited budget.

Enterprise-Class Load Testing Tools: They usually offer the Capture / Playback option. They support a large number of protocols. They can simulate an enormous number of users.
