jMeter


The Apache jMeter is a free and open source application designed for load and performance testing. The functionality of jMeter extends across many different applications, servers, and protocol types. In the context of web applications, we might be tempted to compare it to the browser. However, jMeter works with HTTP and https at a protocol level. It does not render HTML or execute JavaScript. Although jMeter is primarily a GUI application, it can easily be installed and have its tests run in console mode. This makes it a convenient tool of choice for quickly building our tests in GUI mode, and then running them on a server console later on.

Assuming that we are using the Ubuntu 16.10 (Yakkety Yak) installation, installing jMeter as a tool is easy, as shown in the following command line:

sudo apt-get -y install jmeter

However, this might not give us the latest version of jMeter, in which case, we can get one from the official jMeter download page (http://jmeter.apache.org/download_jmeter...
