Performance testing tools

After the first internal beta version of the software system is released, performance testing is a common problem. We need to use different tools to complete the entire test process. Next we will introduce several commonly used tools.

Jmeter

The basic concepts of Java open-source tools are as follows:

1. thread group: in the test, each task must be processed by a thread. All subsequent tasks must be created under the thread group. You can create a thread group in "test plan-> Add-> thread group", and then there are several input columns in the thread group panel: thread count, ramp-up period (in seconds) number of cycles, in which ramp-up period (in seconds) indicates that all threads have been created during this time. If there are 8 threads and ramp-up = 200 seconds, the thread startup interval is 200/8 = 25 seconds. The advantage is that there is no heavy load on the server at the beginning.

2. sampler: it can be considered that all test tasks are undertaken by the sampler. There are many types of tasks, such as HTTP requests.

3. assertion: determines whether the result of the request returned by the sampleer is correct.

4. Monitor: it displays and counts some data (throughput, kb/s…) on the result of the samplete request ......) .

Stress Testing is aimed at testing the software response speed, especially when a large number of concurrent users access the software in a short period of time. This document uses jmeter as an example to describe how to use it to perform common stress testing: Web Testing, database testing, and JMS testing.
