Create a new test for a class that is not well covered

Most integrated development environments have tools that will create a test stub that is a good beginning. Apache Netbeans has "Create / Update tests" . JetBrains IntelliJ has "Create tests". Visual Studio Code has the "Extension Pack for Java".

Use the IDE or your own coding to create a test for one of the classes that is not well covered by tests.

Keep the test small so that the pull request is easy to review.
