27.1 Test Suite Components

Each test suite under ~ns/tcl/test is written to verify the correctness of a certain module in ns. It has 3 components:

• A shell script (test-all-xxx) to start the test;
• A ns tcl script (test-suite-xxx.tcl) to actually run through the tests defined.
• A subdirectory (test-output-xxx) under ~ns/tcl/test, which contains thecorrect trace files generated by the test suite. These files are used to verify if the test suite runs correctly with your ns.

(Note: xxx stands for the name of the test suite.)
