PyCharm - no tests were found?

Question

I've been getting na error in PyCharm and I can't figure out why I'm getting it:

No tests were found

This is what I have for my point_test.py:

import unittest
import sys
import os

sys.path.insert(0, os.path.abspath('..'))

from ..point import Point


class TestPoint(unittest.TestCase):
    def setUp(self):
        pass

    def xyCheck(self,x,y):
        point = Point(x,y)
        self.assertEqual(x,point.x)
        self.assertEqual(y,point.y)

and this point.py, what I'm trying to test:

import unittest

from .utils import check_coincident, shift_point

class Point(object):
    def __init__(self,x,y,mark={}):
        self.x = x
        self.y = y
        self.mark = mark

    def patched_coincident(self,point2):
        point1 = (self.x,self.y)
        return check_coincident(point1,point2)

    def patched_shift(self,x_shift,y_shift):
        point = (self.x,self.y)
        self.x,self,y = shift_point(point,x_shift,y_shift)

Is it something wrong with my run configuration? I looked at this SO post but I'm still utterly confused. My run configuration currently looks like this:

Solution 1

In order to recognize test functions, they must be named test_. In your case, rename xyCheck to test_xyCheck :)

Solution 2

I know it's more than a year since the question was asked, but I had the same issue and that post was the first result in search.

As I understood PyCharm (or Intellij Idea Python plugin) needs your test to meet the following criteria if you want it to be launched when you run all the tests in directory.

1. test functions should start with "test" (underscore is not necessary)
2. the file, containing the test should also start with "test". "Test" (with capital T doesn't work in my case

I'm using Intellij IDEA 2016.3.5 with Python plugin

If you want to run you tests with command line

python -m unittest

Then you should add __init__.py to test directory. Python still wants your test function names to start with "test", and you test file name to start with "test", but in case of files it doesn't care if the first "t" is capital or not. TestCase and test_case is equally fine.

Solution 3

One thing that can also cause this problem is if you have not selected the right testing framework in your settings:

settings > Python Integrated Tools > Testing > Default test runner

All my tests are in pytest, but it was set to unit test

Solution 4

Another gotcha that has just bitten me.

I had a test file within my test package called test_queue.py which followed all of the above advice, however when I selected "Run UnitTests" in PyCharm the console reported no tests found.

The issue in my case was that I had a non-unit test file in the root of the project also called test_queue.py which had been used for some other purpose early on in the project and forgotten about.

Even though I was specifically selecting the test file in my tests folder, and the path was set to absolutely point at the unit test version of the file, it seems the file in the root of the project was being used.

So, one more thing to check, make sure there are no other files in your project with the same name.

Solution 5

Don't use dashes ("-") in your filename. These files were being ignored on my machine. renaming them from project-tests.py to project_tests.py solved the problem.

perhaps this will be useful to you: intellij-support.jetbrains.com/hc/en-us/community/posts/… to stop running in test mode.

For me the file containing the tests has to start with test_

[Calvin Li]

Echoing what Ilya's answer, you also need to name the test files test_... otherwise you can't run the tests from their directories

[Georgios Syngouroglou]

Keep in mind, if your tests are inside of a class, the class name should also start with the word Text. This question uses the class name TestPoint, which is correct. You could have the same error if your class name was PointTest.
