The Java Component Test Report

A component test report summarizes all test results. It is hyperlinked to the test script (in this case, the file TestPhoneNumber.java) and can be browsed using the Report Browser on the left-hand side of the screen..

At the top of the report is an overall summary of test execution. Notice the Passed and Failed items - of twelve tests, only ten passed. Not good news.
