ResourceManager cannot be instantiated during junit testing bug

[wee-zard]

Arrange:

• Configuring the environment (with for example Gradle v3.3).
• Importing the junit .jar files, so we can run junit test cases.

Act:

• Creating a TestFile where we want to run the test case.
• Making an instance of ResourceManager Class
• Check if the instance is created of not with assertNull.

Excepting:

• We can make an instance of the ResourceManager class and run different test cases on it to check, if it's working properly or not.

Actually:

• During the test, we got a NullPointerException.
