The diagram above illustrates the various pathvIEw components and the processes involved.
(1) Standard Gen source code is generated (from the toolset or encyclopaedia). Prior to compilation, it is modified by the pathvIEw Source Code Post-Processor, which adds in calls to the pathvIEw runtime to log statement executions.
(2) The modified source code is then installed and made available for execution in the testing region.
(3) On execution of the application, statement coverage data is gathered by the pathvIEw runtime, and sent (using TCP/IP) to the pathvIEw Listener at the end of the transaction. The Listener stores the execution results in the pathvIEw database. The Listener is a multi-threaded application that supports the logging from multiple application executables in parallel.
(4) The code coverage data can be viewed at any time using the pathvIEw client.
