Issue 13932: If some test module fails to import another module unittest reports a very misleading message (original) (raw)

If some test module (say, testmath) fails to import some other module, unittest reports a very misleading message:

AttributeError: 'module' object has no attribute 'testmath'

Would it be possible improve the message or, better, to simply make the test as failed. (Maybe be by inspecting the ImportError exception message).

Consider the following example (and notice the typo at "import mathhh"):

mkdir -p test touch test/init.py cat > test/testmath.py <<EOL import unittest import mathhh class MathTestCase(unittest.TestCase): def testSin(self): self.assertEqual(math.sin(0), 0) EOL python -m unittest test.testmath

it returns
