Load testing is necessary and should always be part of your testing before production.
Never underestimate the importance of load testing.
'It is always interesting to see that people cram their projects full of unit tests but not a single performance test.'
Performance problems are often overlooked until the software completely fails.
Software with bugs and problems that hinder or limit its use can make the difference between a company’s success and failure, the ability to attract/loyalize users or lose them to the competition.
Improving your system’s performance through rigorous practices and continuous testing is a great way to detect problems ahead of time.
Why should I do the load tests
Load testing is a non-functional software testing process in which the performance of the software application is tested under a specific expected load.
Basically, it is imposing a load on the system to see how it performs. For example, simulating 15,000 concurrent users on a website
During this time, we can collect many valuable metrics, such as average response time or average number of requests per minute.
3 Advantages of Load Testing
Testers 🐞— By using load-testing, you can simulate thousands of test users
It helps you check for performance bottlenecks before deploying to production.
It reduces the possibility of downtime by checking and isolating requests that need to be improved and made better.
Performance 🚀— With load-testing, you can find and fix performance issues before users will find them.
Load testing is a kind of performance testing. It will help you to minimize the risks associated with performance requirements and support continuous process improvement by supporting performance tuning.
After a new release, they are useful for determining whether the performance of the application under test will improve or degrade under expected load conditions.
Confidence 💪🏾 — It gives a sense of confidence and reliability before the application is released.
Be confident that your application can handle thousands of users.
3 tools for Load Testing
There are many load testing tools available today for all kinds of applications and organizations.
Here are three if you finally decide to get into load testing:
Apache JMeter is one of the most commonly used open-source performance testing tools for load testing. It was originally developed for testing web applications or FTP applications.
“Locust — A modern load testing framework”
For load testing https://locust.io and gatling are easy to integrate in the pipeline.
Keep in mind that “For software to work successfully, it is essential to run performance tests.”
