CSC 357 Program 2 Test Plan

This is an input/output test plan for programming assignment 2, in the standard 357 format. Additional explanatory information is in the test plan for programming assignment 1

The test-execution script is run.csh. It assumes a program named nwc exists in this directory. The script must be run on falcon or hornet in order to find testing files with specific UNIX paths.

Most testing input is from files in the inputs subdirectory. Cases 1, 2, 7, and 8 have no command-line file inputs. Cases 19-22 take input from files in standard locations in the falcon/hornet file system. The expected-output subirectory has the expected output for each test case. The naming convention for the output files is

case-number:input- filename.[err]out

Here is an excerpt of a typical case from run.csh:

       #
       # Case 4.
       #
       if ($1 == "-v") echo Case 4
       timelimit 15 ./nwc inputs/10-wds > output/4:10-wds.out
       

The script diff-case uses UNIX diff to compare actual and expected outputs. The script takes the case number, the output file, and the number of points for case. It produces no output if there are no differences.

Depending on an implementation, some of the test cases may take a while to run. Since no terminal-visible output appears when a correct program runs, you'll see no sign of progress. If you would like to see output progress as each case runs, use the "-v" option.

	Inputs:
Case	file arg(s)	-n arg	Output	Remarks	Points

2		xxx		usage message; output message is to stderr, with no output to stdout	2
3	empty		empty.out	empty input file	2
4	10-wds		10-wds.out	ten different words in input file, exactly ten words long	10
