6 # Tests in the test file have a syntax similar to mail headers,
7 # individual test case are separated by blank lines and they can contain
8 # the following fields:
10 # Name: name of the case (default: sequence number since start of file)
11 # Run: command to run (default: command from the previous test case)
12 # This can be an arbitrary shell pipeline, sequences $0 to $9 are
13 # replaced by file names of In<N> or Out<N> files (see below).
14 # In: lines to pass to the program as standard input
15 # Out: lines to expect at the program's standard output
16 # In<N>: lines to pass to the program as input file <N>
17 # Out<N>: lines to expect from the program in output file <N>
18 # Both In<N> and Out<N> can be specified simultaneously if we
19 # are testing a program which modifies some of its input files.
20 # Exit: expected exit code of the program (default: 0)
