Jmeter's first use

1. Install jmeter

Http://apache.etoak.com//jmeter/binaries/apache-jmeter-2.9.zip

Click jmeter in the bin directory to start. An error is reported because JDK is not installed. After JDK is installed, configure the environment variable. directly add it in path. C: \ Program Files \ Java \ jdk1.7.0 _ 21 \ bin

2. Start successfully. Create a test plan, create a thread group, and configure the number of threads and startup mode.

3. Add an HTTP request. Enter the request URL directly in the path.

4. Add the listener to aggregate the report and click Start to execute the report. Then, you can observe the throughput and other metrics...

Summary

It seems very simple. At the beginning, I still got a mistake. There are three thread groups. I checked them. According to the explanation of the wormhole, I still want to learn from young people. There are too few things to study, if you are younger, you will be out of date!

Although there are three options for adding a thread group with different names, the interface is identical after creation. The previous version only has the name of a thread group. Now there is one more setup theread group and terdown thread group.

1) setup thread group

A special type of threadgroup that can be used to perform pre-test operations. These threads act like a normal thread group component. The difference is that these types of threads perform regular thread group execution before testing.

2) teardown thread group.

A special type of threadgroup that can be used to perform post-test actions. These threads act like a normal thread group component. The difference is that these types of threads execute regular thread groups after testing.

Maybe you still don't quite care about the differences between them and common thread groups. If you have used JUnit, you may not be unfamiliar with setup or teardown. It does not matter if it is used in real time. Familiar with LoadRunner, we should know that the LoadRunner script is not only the core content of the real script in the action, but also the initialization script for initializing the "Environment" and the script block for clearing information after the test. Here, setup thread group and teardown thread group respectively refer to these two parts. In essence, they are no different.

3) thread group (thread group ).

This is the thread we usually add to run. Generally speaking, a thread group can be considered as a virtual user group. Every thread in the thread group can be considered as a virtual user. The number of threads in the thread group will not change during the test execution.
