Three great weapons in eclipse

Two great weapons in eclipse:

Let's start with Eclipse development tools. Java code, development, when we develop the completion. Need to test. Most of us use junit testing tools, but internal code coverage. and structure we are not looking so detailed.

One. Test code coverage with coverage that is used with JUnit

How to use: In Eclipse, click the Help button to find the Eclipse marketplace, and find the coverage results as follows:

Install directly installed, complete, and restart eclipse later. You can start using it.

Reboot later in Eclipse. You look at this button.

It is convenient to use. Right-click in the class that you want to test. You will see coverage as this option. There's going to be a junit test in there. "The JUnit test tool must be installed"

First, install the Jprofiler

Download 5.1.2 from http://www.ej-technologies.com/and request a trial serial number
