I have written JUnit tests for my class, and would like it to tell me if there is any part of my code that is not unit tested. Is there a way to do this?

Unit testing can be done manually but is usually automated. Unit testing is a part of the test-driven development (TDD) methodology that requires developers to first write failing unit tests. Then they write code in order to change the application until the test passes.
Is unit testing manual or automated? Unit tests are usually automated because it's too costly, time-consuming and difficult to isolate units manually. The issue is that unit testing is a part of the web development/app development process.
UNIT TESTING is defined as a type of software testing where individual units or components of a software are tested.
Code coverage on automated or manual tests is more like a nice to have activity. We can live with or without it. It is useful for big matured products where there are automation test suites. You can also do them against your tests code in order to optimize it.
Yes, coverage tools like cobertura or emma.
They create reports that show every line in the source code and whether it was executed or not (and aggregated statistics as well).
Of course, they can only show you if the code was run. There is no way to tell if the unit test contained assertions to confirm that the result was correct.

You need some code coverage tools. See here (http://java-source.net/open-source/code-coverage) for some
If you look at the first one I think it does what you need
Cobertura is a free Java tool that calculates the percentage of code accessed by tests. It can be used to identify which parts of your Java program are lacking test coverage. It is based on jcoverage. Features of Cobertura:
