3.5. What is a .jtr file?

As each test is run, it produces a JavaTest Results (.jtr) file which contains information about how the test was run, the name of the test, standard output, standard input, final status, etc. The name of the file is the basename of the file containing the test description followed by the .jtr extension. For example, Hello.java produces a file called Hello.jtr. These files reside in the work directory which contains a directory hierarchy that parallels the source structure.
