This looks similar to #53, and the fix is to wrap your expected output in " chars.

I'm guessing you were doing something like this (script saved as test_equals.sh).

#!/bin/bash
cmd() { echo ''; }

test_cmd1() {
  assertEquals "cmd() failed" "" $(cmd)
}
test_cmd2() {
  output=$(cmd)
  assertEquals "cmd() failed" "" ${output}
}

. ~/lib/sh/shunit2

This will produce the behavior you are seeing.

$ ./test_equals.sh 
test_cmd1
ASSERT:expected:<cmd() failed> but was:<>
test_cmd2
ASSERT:expected:<cmd() failed> but was:<>

Ran 2 tests.

FAILED (failures=2)

Wrapping the output fixes the problem in both cases.

#!/bin/bash
cmd() { echo ''; }

test_cmd1() {
  assertEquals "cmd() failed" "" "$(cmd)"
}
test_cmd2() {
  output=$(cmd)
  assertEquals "cmd() failed" "" "${output}"
}

. ~/lib/sh/shunit2
$ ./test_equals.sh 
test_cmd1
test_cmd2

Ran 2 tests.

OK

from shunit2.
