Root Cause

unittest discovery found no tests because the module/class/method naming didn't match the pattern (test*.py, TestCase subclass, test_* method), or the start directory was wrong.

generic

中文

unittest 发现没有找到测试，因为模块/类/方法命名不匹配模式（test*.py、TestCase 子类、test_* 方法），或者起始目录错误。

Workarounds

  1. 95% success 
    # tests/test_calc.py
import unittest

class TestCalc(unittest.TestCase):
    def test_add(self):
        self.assertEqual(1+1, 2)

# run
python -m unittest discover -s tests -p 'test*.py' -v
  2. 90% success 
    python -m unittest discover -s . -t . -p '*_test.py' -v

Dead Ends

Common approaches that don't work:

  1. 95% fail

    Verbosity shows the same 'Ran 0 tests'; it doesn't fix discovery.

  2. 60% fail

    Different discovery rules; may still collect zero if names are wrong.

  3. 70% fail

    Only affects direct execution, not discovery.
