Chapter 6 - Running a Test

A plain Java file, "TestJavapp.java", contains a test program for "SimpleClass.java" and "ComplexClass.java". Running the test produces the diagnostic System.err messages listed and commented in "stderr.txt".

6.1 - Code Examples top

Code Example 8 - tjpp test class
Line 16 causes an assertion to fail and a trace message to be printed out. Each line between 17 and 20 produces one trace message.
