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:
Answers:
In order to recognize test functions, they must be named test_. In your case, rename xyCheck to test_xyCheck 🙂
Another issue you may want to check is if you see in the console output “## tests deselected by ‘-k XXXX’“. This means you’ve added a Keyword to the Run/Debug Configuration, and Pycharm will only run tests whose name contains the keyword.
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.
- test functions should start with “test” (underscore is not necessary)
- 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.
Adding another answer in the hopes that it helps someone down the road. I’ve been fighting this problem and just figured out the answer (I think). I originally deleted the standard Django file tests.py out of my application folder. I also created a subdirectory of my project called tests, which contains separate test scripts. In this situation, Pycharm failed to find the tests. I corrected this simply by creating an empty file called tests.py in my application folder.
So:
- Make sure you have a file called tests.py in your application director (it can be an empty file)
- It seems that a folder called tests, in your project, can contain separate test scripts and Pycharm seems to find and run these.
Here’s a picture of the directory structure that’s working for me:
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.
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.
I had this exception when running individual tests in a Django 1.8 project in PyCharm 2018.1. I could run all the tests together, but individual tests in one file crashed.
The exception was happening in unittest’s loader.py
It was getting an ImportError trying to import test_admin_views.py, though the exception was hiding the details of that error.
To see the details of the ImportError, I opened a Python Console and ran:
import my_app.users.tests.test_admin_views
This gave me:
Traceback (most recent call last):
[...]
File "my_app/my_app/users/tests/model_factories.py", line 42, in <module>
from my_app.applications.tests.model_factories import ApplicationFactory
ImportError: cannot import name ApplicationFactory
I noticed that some of the other factories in that file are imported without using the full path, so I tried adding ApplicationFactory to the relative path import list:
from .model_factories import UserFactory, UserGroupFactory, ApplicationFactory
Which worked!
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
None of these helped me, but I was able to fix the issue by setting the working directory to the project directory.
I debugged this by first creating a new Django test configuration witj a target of one of the app names with tests.
That ran successfully. No idea why working directory should need to be specified.
i found the solution , im a beginner , forgive me if its not working,
- if unittest in pycharm is not working …(you will know when , even your file to test is deliberately wrong , pycharm will tell you its OK , or pass)
- pres CRTL ALT S —->> Testing —->> change to pytest , will show hazard like symbol at bottom —->> press fix —->> apply —->> ok..
- the only modification to your code will be to add this in the end .
