Detailed Description

Suite of tests for the WREB controller board.

This program communicates directly with the Jython interpreter to manipulate the board, so it does not need to be loaded into the Jython exectuor.

External dependencies:

astropy
numpy
matplotlib
Unix Dialogs installation (for GUI, optional)

To run:

"python REBTest.py [options]" Initial crashing yielding a ValueError is likely due to a crRun or JythonConsole crashing or not being loaded.

Tests are structured as classes with four required methods:

init sets initial variables; minimum required variables are self.title and self.status.
runTest is the body of the tests, running the code to execute the tests and storing the results to state variables.
summarize writes summary information to the summary object passed to it; this is used in generating the cover page.
report writes the portion of the pdf report that the test is responsible for. Tests are executed from a list of test objects defined in FunctionalTest().
