Unit test

Let's create a unit test that proves the method works as expected. By now, you should be able to create a UtilsTest class in the test/java/com/packt/javapath/ch06demo directory (or in the test\java\com\packt\javapath\ch06demo directory in the case of the Windows). The test should look like this:

@DisplayName("Utils tests")public class UtilsTest {  @Test  @DisplayName("Test reading value from config file by key")  void getStringValueFromConfig(){    //test body we will write here  }}

{  "unknown": "some value"}

It will play the role of a config file. With that, the test code looks as follows:

@Test@DisplayName("Test reading value from config ...
