If <test>.exp exists, <test>'s output is diff'ed with <test>.exp. Any
difference is considered failure.
If <test>.exp does not exist, output to stdout of the following form is
expected:
1..<n>
{not }ok[ 1]
{not }ok[ 2]
...
{not }ok[ n]
1 <= <n> < 2^31
Lines which do not match the patterns shown above are ignored.
