describe be
it cannot stand alone
expect _expect--be 0 2
to fail
end
it processes remainder clause as if it did not exist
(
expected="foo bar baz"
_expect--awesome() { shift "$2"; test "$*" == "$expected"; }

to succeed
)
end

describe succeed
it will succeed when command exits with status code 0
expect _expect--succeed 0 2
to succeed
end
it will fail when command exits with non-zero status code
expect _expect--succeed 1 2
to fail
end

it will succeed when command exits with non-zero status code
expect _expect--fail 1 2
to succeed
end
it will fail when command exits with status code 0
expect _expect--fail 0 2
to fail
end
end
describe not
it will invert the result of an expectation
# exit code of 1, so normally `succeed' would fail
expect _expect--not 1 2 succeed
to succeed
# exit code of 0, so normally `succeed' would succeed
expect _expect--not 0 2 succeed
to fail
end

it will default to asserting against stdout
expect _expect--output 0 2 "test string" <<< "test string"
to succeed

it can assert against stderr output
{
expect _expect--output 0 3 /dev/fd/3 \
"test stderr" on stderr
to succeed

it fails on stdout mismatch

to fail

it ignores exit code

# as is good practice for Unix utilities
it expects trailing newline by default
expect _expect--output 0 2 "foo" < <( echo -n foo )
to fail
end
it can disable trailing newline check with "'without newline'" clause

it errors on any unrecognized clause

to succeed

it will match against a pattern
expect _expect--match 0 2 "^foo.*baz" <<< "foo bar baz"
to succeed

to fail
end
end

it succeeds when both stdout and stderr are empty
# omitting stderr arg

to succeed
