Performance testing

Comprehensive check at all stages of the software life cycle


Evaluation of product behavior under the expected load

The task of load testing is to determine the scalability of the application under load. When this happens:

  • measurement of the execution time of selected operations at certain intensities of these operations
  • determination the number of users simultaneously working with the application
  • determination of the limits of acceptable performance with increasing load (with an increase in the intensity of these operations)
  • performance investigation at high, marginal, stressful loads


Determination of the maximum load of the software and assessment of the system stability at peak loads

Stress testing allows you to check how the application and the system as a whole work under stress and also evaluate the ability of the system to regenerate, i.e. to return to normal after cessation of stress. Stress can be an increase in the intensity of operations to very high values ​​or an emergency reconfiguration of the server. Also, one of the tasks in stress testing can be to evaluate performance degradation, so stress testing objectives can overlap with performance testing objectives.


Analysis of the performance of the product during long-term testing with the expected level of load

The task of testing stability (reliability) is to test the performance of the application during long (many hours) testing with an average load level. The execution time of operations can play a minor role in this type of testing. At the same time, the absence of memory leaks, server restarts under load, and other aspects affecting precisely the stability of work takes the first place.


Checking the application work with an increase in the amount of data used

The task of volumetric testing is to obtain an assessment of performance with an increase in the amount of data in the database of the application, and this happens:

  • measurement of the execution time of selected operations at certain intensities of these operations
  • can determine the number of users simultaneously working with the application

Why do we need load testing?

Imagine that you need to add new functionality, adjust the configuration, and you fear that the system will not be able to serve the business due to the increasing load on it. Then you need to assess the current capabilities of the system. Load testing is performed in order to understand whether the system can withstand the required load. This type of testing allows you to pre-determine possible problems related to the application performance and fix them in a timely manner.

Phased load testing

Our specialists study each project in detail and perform testing based on its needs and limitations.


  1. Studying the object of testing. A comprehensive analysis of constraints and requirements allows you to develop an effective testing methodology. With load testing, a lot depends on the expected load on the software product and its functionality, which will be under load.
  2. Planning and preparation. At this stage, a testing methodology is developed, a load profile.
  3. Setting up the test environment. Load testing of servers requires preliminary preparation of data, setting up parameters of work of load generators, monitoring systems and other elements.
  4. Testing scripts development. This stage is conducted with the business requirements of the product.
  5. Run performance tests. During testing, the application is analyzed in different conditions, defects are detected.
  6. Data analysis, reporting.

Test results

Load testing allows you to find answers to the following questions:

  • How does the product handle the expected load?
  • Do you have enough hardware resources to handle the expected traffic volume? An analysis of the state of computing power.
  • How quickly does the server respond to user requests? Analyzed the speed of operations. Low speed and failures under load reduce the efficiency of the application, block its work, increase the risk of losing customers.
  • Is computational capacity scaling required?
  • Are there resource-intensive operations on the site that need optimization?

Failures in product performance can adversely affect a company's business. Load testing software - the ability to prevent failures in its work and ensure stable operation of all components. We will identify current problems and identify hidden defects that may adversely affect the operation of the software.
