Load tests should be performed all the time in order to ensure your system is always on point, which is why it should be integrated into your continuous integration cycles utilizing tools such as Jenkins and Taurus.
A stress test is a type of performance test that checks the upper limits of your system by testing it under extreme loads. Stress tests examine how the system behaves under intense loads and how it recovers when going back to normal usage. Are the KPIs like throughput and response time the same as before spike in load? Stress tests also look for memory leaks, slowdowns, security issues, and data corruption.
Stress testing can be conducted through load testing tools by defining a test case with a very high number of concurrent virtual users. Just as a stress test is a type of performance test, there are types of load tests as well. If your stress test includes a sudden, high ramp-up in the number of virtual users, it is called a Spike Test. We presume the system will be under traffic three minutes into the test.
Run stress tests against your website or app before major events, like Black Friday , ticket selling for a popular concert with high demand, or elections. Utilize all the types of performance tests detailed here to ensure you are always aware of any issues and can have a plan for dealing with them.
JMeter can be enhanced through BlazeMeter, which provides larger scalability, many geo-locations around the world, better reporting and sharing capabilities, multiple integrations, and recording options.

Break Point : If we keep increasing the load on the server, there comes a point when the server cannot handle any more requests and it crashes, most probably starting to give a http error response code.

Finally, load testing allows you to predict how a planned release will work or not before an update goes live. One way of describing stress testing is "extreme load testing". Stress testing is a kind of performance testing that happens when you push your app, API or software to the upper limits of its capacity.
It works to reveal how your system will hold up under a sudden surge of demand when your current number of users goes beyond the maximum levels you can support. Configuration testing : This type of testing helps you find any changes to the pieces of your system that affect behavior or performance. Endurance testing : This monitors continuous load, red-flagging any slow leaks that may be slowing you down or wasting resources.
Isolation testing: Isolation testing is used to try to zero in on a specific problem in hopes of finding its cause and fixing it. Doing load testing here helps us achieve two things.
First, it ensures that the app can indeed carry the estimated 10 active users. Second, it avoids the situation presented above. Application defects that cause data loss or memory leaks are also examined and found. It happens that such an application or website works very well in a limited environment for a small number of recipients. However, under the influence of increased activity, various unpleasant things start to happen.
As an example, a gaming company decides to release an online game. Many incoming data resulted in overloading and complete shutdown of the servers, and players lost server connection for several hours until the failure was resolved. As you would expect, the players felt disappointed that they could not play the game, even after purchasing the premier package. In contrast to a load test, an early stress test in the above example would have helped ascertain the maximum number of active users the game app could carry before the servers broke down.
And of course, validate if the software can tolerate errors while handling this maximum load. Apache JMeter: is among the most common and popular tools dedicated to performing performance, stress, and functional tests. This program is written in Java and free-to-use. It allows users to download additional plugins.
Its GUI is easy-to-operate but when performing load tests, it is advisable to execute using commands from the CMD console. This lets the user run tests from multiple machines at once. Also, you can collect and analyze statistics in detail, and generate reports. The GUI with Java is reflected in the application speed, which may disturb the measurements. JMeter can be used primarily to send GET requests.
