The page of a job contains the Test Result Trend as a graph (passed tests green, failed tests red).

When a build fails before executing JUnit (e.g. because of a compilation error), the graph shows the same test result as for the latest successful build, even though zero tests were executed. Apparently the junit test result is left untouched when a build doesn't proceed to the test phase.

This is misleading, as the unchanged state in the graph seems to indicate that all is well, even though it isn't.

IMHO the test result should rather show zero tests instead.
