In this case, the ReflectionUtils.tryToReadFieldValue() method is used to access the field folder . The field folder is declared in the JUnitRuleExample class and is used to store the current folder. The JUnitRuleExample class is a JUnit 4 class, and the field folder is declared with the @Rule annotation. The JUnitRuleExample class is used in the JUnitRuleExampleTest class, which is a JUnit 5 class. The JUnitRuleExampleTest class has a field named folder , which is
