| | Sherpa: Regression Test Procedures |
 | | Sherpa is an interactive application; users type in commands at the command line, and Sherpa functions are executed in response. |
 | | Sherpa normally sends much of its output to stdout (e.g., the "fit" command by default displays the fit statistic at the end of each iteration, and the best-fit values of the thawed parameters upon completion; and, the options to the "show" command print out much information, and so on). |
 | | Later, after more Sherpa development, one wishes to test that changes introduced into the code do not change the output for these test scripts; so the output from one's "development" version of Sherpa can be compared to output from the last "approved" version. |
