What is Load Testing?

What is load testing

Load Testing Definition

Load testing is a type of non-functional software testing that helps ensure a system’s behavior, performance and stability when exposed to expected and unexpected (extreme) load. Load testing can help you gather information about:

  • Number of concurrent users and requests that the system can handle
  • Sustainability of the network traffic generated by all requests within a user session
  • The operating capacity and scalability of the server infrastructure

Load Testing with Test Studio

Load tests are a collection of REST requests that Test Studio’s load engine runs in parallel, as fast as possible. This process provides critical information about the system’s resistance against the load, indicating the impact on the user experience.

  • Create load tests from automated web tests and run them for numerous concurrent users
  • Customize your load tests to meet your specific load testing needs
  • Use load testing to verify the performance of your web services

Low-Code Configuration

Use any number of tests you need to create complex usage scenarios that mimic your site’s actual usage. This helps you assess whether your web application meets business requirements for availability and scalability. Test Studio provides you with the flexibility to create elaborate, complex load scenarios and acquire the data you need to make informed decisions. Follow the load testing best practices compiled by the Test Studio team to successfully introduce load testing into your overall testing strategy.

Multiple Load Test Sources

Test Studio allows you to create load tests on top of your existing web test automation. Capture web traffic from multiple browsers with Test Studio’s load test recorder or import Fiddler Everywhere traces to build test cases out of the invaluable data these logs provide, directly in Test Studio. Get started with load testing for your web applications in no time.

Real-Life Condition Simulation

Test Studio provides a list of auto-detected dynamic targets to pick from when crafting a load test. You also have the option to create your own custom dynamic targets to maximize testing effectiveness and cover all possible load testing scenarios, including mobile traffic.

Creating load tests to simulate traffic from mobile devices is as easy as it gets. Test Studio enables you to create user profiles to channel the traffic your web app gets from various mobile devices. Designing scenarios that represent different traffic channels (web browser, desktop client and mobile device) enables better real-world simulation of user load against a site or a web service.

Smart Diagnosis of Issues

Set your goals and benchmarks and then run your test. Validate your web application performance under load based on metrics such as average response time, total errors, traffic size, time to first byte and more. Analyze and compare results from different test runs in one easy to understand chart. Test Studio highlights areas where your system may be failing to meet load and performance goals, helping you stay focused on the key performance indicators.

Scheduling and Distributed Runs

Test Studio’s Run-Time engine gives you robust remote load test scheduling and execution infrastructure, enabling you to create combined test lists of functional, performance and load tests, as well as exclusive load test lists. You can schedule them to run across all available workstations in parallel to speed up the execution of large test lists and accelerate your overall testing process.

Load Testing of Web Services

Modern web applications employ a variety of web services, the quality of which is a key factor in user satisfaction. Test Studio allows you to get information about server performance and stability such as throughput, CPU usage and web methods’ response time when there are thousands of concurrent users. Whether you use in-house or third-party services like stock market tickers, weather reports or news feeds, Test Studio enables you to load test your web services and ensure that their performance meets your standards.

What QAs Say

Telerik Test Studio enables our quality assurance team to quickly identify potential bugs pre-release within the DevOps pipeline. We have been able to scale and accelerate delivery of new features while reducing our manual testing on existing functionality. The features are deep, yet easy to use. The consistent addition of new and improved features helps improve the efficiency of our testing efforts.

Mike Goodwin Director of Technical Support and Quality Assurance, Kiddie Academy®

Headless execution allows us to greatly reduce the overall time needed to complete a test cycle. This method also allows us to integrate Test Studio into our CI pipeline so we can run any portion of the test plan at the time of merge and/or deployment.

Zachary Hansen Chief Technology Officer, Angus Energy

Test Studio is a fantastic platform for anyone who's new to automated testing because it's got a very intuitive UI, but also for somebody who's highly skilled as they can immediately pick up on what Test Studio can do and make very effective use of the tool.

Pete O'Grady QA Manager, RevSpring

Test Studio ließ sich nahtlos in unsere automatisierten Testkonzepte einbinden. Es ist unglaublich, wie komfortabel man damit arbeiten kann. Test Studio nimmt dem Entwickler den Großteil der Arbeit ab, so dass er sich stärker auf die tiefer gehenden Testaufgaben konzentrieren kann.


The best thing about Test Studio is easy ramp up which enables anybody to start creating tests within a few days. The centralized element repository is very comfortable, bringing down test maintenance costs.

Himanshu Saraowgi QA Engineer, Pegasystems

After using the trial for a week we increased our automated testing from 5% to 30%. Test Studio was so easy to incorporate into our existing testing environment! Tests are stable and easy to run and understand.

Mark Judson Software Developer, EBSCO Industries Inc.
