Switching from TestNG to JUnit

First of all, we need to make some changes to our POM.xml to use JUnit instead of TestNG; we will start with the properties block:

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF- 
    8</project.reporting.outputEncoding>
    <java.version>1.8</java.version>
