JMU CS Wiki

This page provides information about the feedback provided by the autograders that use gradingtier (and Checkstyle, JUnit, and JaCoCo/EclEmma) to assess Java programming assignments.

Feedback about style includes a list of defects (generated by Checkstyle) organized by file that looks something like the following.

Feedback about correctness includes a list of test failures (generated by JUnit). You may be given information only about the test, in which case it will look something like the following.

You may also be given hints, in which case it will look something like the following.

Or, you may also be given detailes about the failure, in which case it will look something like the following.

Feedback about the coverage of your tests (generated by JaCoCo/EclEmma) is organized by class and method, and looks something like the following.

Note that if a method contains no branches then the branch coverage line will be omitted. Note also that JaCoCo uses the term “branches” differently from the way some other people do. Specifically, the number of “bracnhes” is the sume of the number of possible Boolean values in an expression.
