An Introduction to Load Testing
Content
This helps you quickly and easily create performance tests for your web service. Performance testing mobile apps can be performed in the same manner as testing for desktop or web-based applications. If the app is simply local and does not require a network connection, then load testing may not be a very valid form of testing for your mobile app.
Many use it for debugging to view the HTTP requests their computer is sending to a service or website. Taurus basically fits performance testing into your CI/CD pipeline much more efficiently. This should also allow more team members to contribute to performance tests. Also, since your test cases are written in YAML, the tests are much more readable, making them easier to perform code reviews. Error rate and fails the test if it passes a certain threshold (%50 by default). We can see the response time for each request and are able to drill down and see the error statistics for each one.
Load Testing
This is a good test, given the growing number of users does not affect the response time, the error rate remains low, and the hits per second are in line with the number of virtual users. Different types https://globalcloudteam.com/ of performance tests provide you with different data, as we will further detail. Load testing can only be executed if we have enough knowledge of any programming language as well as testing tools.
Locust can also be run in distributed mode, where you can run a cluster of Locust servers and have them produce load in a coordinated fashion. This facilitates the load testing of powerful web serving infrastructure. If not, log in to your web server via SSH and use the following command line tools to monitor in real-time.

Under a light load, the server started rejecting most incoming connection requests, but allowing just enough through to be suspicious. When the web-server status was reviewed, it was clear that the configuration for maximum threads was set for the default value—in this instance, fewer than 100! A quick configuration on the master configuration that was pushed out to all of the web servers fixed this, and the test was restarted quickly.
Using the various load testing tools, we can ensure to deliver a quality product that cannot crash while maximum numbers of users using it simultaneously. To perform the load testing, we can use the open-source load testing tools as we have various load testing tools available in the market for free of cost. Monitor application performance and fix bugs before your code ever gets to production. Load testing examines how the system behaves during normal and high loads and determines if a system, piece of software, or computing device can handle high loads given a high demand of end-users. This tool is typically applied when a software development project nears completion. One of the few open-source tools that allow you to create performance testing using real browsers to mimic how real users interact with your application more closely.
A Practical Guide to Load Testing
The results will allow you to fine-tune performance based on errors or inconsistencies. These benefits set LoadView apart from other load testing solutions on the market today and puts the control of load testing into the hands of the user. Load testing is the process of testing software performance under a specified load. But even after standard optimization efforts like these, many companies and organizations continue to face problems with handling traffic—either in subsequent load tests, or in real-world high traffic scenarios. To discover how to run less painful, almost free cloud-based load tests, check out Queue-it’s Director of Product Martin Larsen’s guide to getting started with Gatling and RedLine13. This means if you’re expecting 10,000 concurrent users, your test will populate your site with 10,000 users—or maybe 11,000 to give some breathing room—to see how the site manages it.
- If we ignored the load testing, it might cause financial losses.
- The load testing is necessary if any code changes occur in the application that may affect the application’s performance.
- This type of load testing is broader in scope than component testing, but shallower in terms of depth.
- There are different types of performance testing, and one of them is load testing.
- Because the file was not deployed correctly, clicking the calendar icon yielded nothing but a log full of JavaScript errors.
- You may need to change your architecture, replace or change your data models, or even change core business logics and processes.

Stress testing deliberately induces failures so that you can analyze the risk involved at the breaking points, and then, perhaps, choose to tweak programs to make them break more gracefully. Stress testing is useful for preparing for the unexpected and determining exactly how far a given system can be pushed, exploring the outer limits of performance capacity. Licensed load testing tools support many protocols so that load testing could be performed on many different types of applications such as ERP/CRM, Streaming Media etc. Most load testing tools let you record or write a script that interacts with a website or application. Those scripts are then put into test scenarios or scheduled tests. You then identify the scope and the quantity of users required in the test, and the length of time to run the test.
Determining Load Test Requirements
You can set the load testing software to deliver simulations of varying levels and see if applications can work within specific ranges. This is a Load test tool by HP which is used to test the application by generating load. It tests the application by creating virtual users to simulate load test definition normal and peak network traffic conditions. The tool simulates a production environment and displays graphical results. After measuring the performance of your infrastructure, you may want to act on this information to try to improve response times and reduce server load.
To get a more real-world idea of our server’s latency at a given load, we’ll need to test multiple times at different request rates. Not all load testing software is capable of this, but later on we’ll discuss wrk2, a command line load testing tool that can perform this function. JMeter is a Java-based open-source load testing tool used to analyze the performance of websites, applications, web services, and other dynamic resources under high traffic conditions. Difference between load testing and stress testing, which is the reason why they are often confused with each other. Load testing and stress testing are both subsets of performance testing. Performance testing aims to examine system behavior and performance.
How Does Load Testing Work?
Here, LoadView’s web application scripting provided the ability to step through the application with dynamic filtering, load testing the database under excessive user simulated load. While a broad international geographic distribution was not required, load was distributed across 5 datacenters in the USA to provide a more realistic capacity test scenario. Desktop application load testing may be slightly different than load testing for a web-based application. Software may be built on a variety of platforms, from traditional Windows forms to Java applets and web apps. Load testing Windows forms apps may require a very different testing infrastructure than load testing web apps. Web apps may be tested from external environments if the app is on a public facing website, while Windows forms must typically be installed and tested from one or more local computers.
