Question

I\'m looking for a way to run tests on command-line utilities written in bash, or any other language.

I\'d like to find a testing framework that would have statements li

I know that this question is old, but since I was looking for an answer, I figured I would add my own for anyone else who happens along.

Full disclaimer: The project I am mentioning is my own, but it is completely free and open source.

I ran into a very similar problem, and ended up rolling my own solution. The test code will look like this:

from CLITest import CLITest, TestSuite
from subprocess import CalledProcessError


class TestEchoPrintsToScreen(CLITest):
    '''Tests whether the string passed in is the string
    passed out'''

    def test_output_contains_input(self):
        self.assertNotIsInstance(self.output, CalledProcessError)
        self.assertIn("test", self.output)

    def test_ouput_equals_input(self):
        self.assertNotIsInstance(self.output, CalledProcessError)
        self.assertEqual("test", self.output)

suite = TestSuite()

suite.add_test(TestEchoPrintsToScreen("echo test"))

suite.run_tests()

This worked well enough to get me through my issues, but I know it could use some more work to make it as robust as possible (test discovery springs to mind). It may help, and I always love a good pull request.
