There is no @Test annotated methods in class given in TestNG suite 2. @Test annotation is imported from junit package instead of TestNG 3. @Test method access specifier is not public 4.

Eclipse : when trying to run the tests from Eclipse 2019-03 , I get a message that either TestNG cannot find class in classpath or that No tests were found and nothing was run ...

Surefire plugin is complaining that it cannot find a class named [ERROR] Cannot find class in classpath: Configuration.Configuration This class is not part of TestNG.
