21.3 Performing tests

./test.sh blunder.tst runs the tests in `blunder.tst' and prints the results of the commands on numbered lines, which may look like:

 
1 E5
2 F9
3 O18
4 B7
5 A4
6 E4
7 E3
8 A3
9 D9
10 J9
11 B3
12 C6
13 C6

This is usually not very informative, however. More interesting is ./eval.sh blunder.tst which also compares the results above against the correct ones in the test file and prints a report for each test on the form:

 
1 failed: Correct '!E5', got 'E5'
2 failed: Correct 'C9|H9', got 'F9'
3 PASSED
4 failed: Correct 'B5|C5|C4|D4|E4|E3|F3', got 'B7'
5 PASSED
6 failed: Correct 'D4', got 'E4'
7 PASSED
8 failed: Correct 'B4', got 'A3'
9 failed: Correct 'G8|G9|H8', got 'D9'
10 failed: Correct 'G9|F9|C7', got 'J9'
11 failed: Correct 'D4|E4|E5|F4|C6', got 'B3'
12 failed: Correct 'D4', got 'C6'
13 failed: Correct 'D4|E4|E5|F4', got 'C6'

The result of a test can be one of four different cases:

If you want a less verbose report, ./regress.sh . blunder.tst does the same thing as the previous command, but only reports unexpected results. The example above is compressed to

 
3 unexpected PASS!
5 unexpected PASS!
7 unexpected PASS!

For convenience the tests are also available as makefile targets. For example, make blunder runs the tests in the blunder test suite by executing eval.sh blunder.tst. make test runs all test suites in a sequence using the regress.sh script.
