Download jar package
You first need to download the JUnit jar package and a dependent package hamcrest.core, they download the following address:
JUnit: JUnit: 4.13-Beta-1
hamcrest.core: 1.3.0.1
Note that hamcrest.core package version 2.1 can not be used because the 4.13 version of JUnit and it is not compatible, it will throw an ClassNotFoundExceptionexception.
Recommended junit-4.13.jarand hamcrest-core-1.3.jar, otherwise there will be unexpected trouble

Then set it up:
You can change the output path to the desired path
in the position shown above change in the output path does not seem affected. . .

Create a directory test file
You need to create a new folder in the Project, for storing the automatically generated test .java files, such as Factorial.javathe class corresponding to the FactorialTest.javastorage location of the file
where I create a new directory, and the same level directory scr, FIG.
Next you need this folder to store directory generate test file
