Newbie question on tests: I have found a way but it is very fiddly - is there a better way? Spyder is so much easier!

The JetBrains documentation has examples on how to test a class, but I am struggling to understand how to test functions - not classes.

With Spyder and pytest it's pretty intuitive: I install the unittest plugin , tell Spyder in which directory to find the test, and it runs them. I then get an output that looks like this:

How can I do the same with PyCharm?

• In settings - tools - Python integrated tools I have set testing to pytest
• I have create a new project, with a file called main.py and a banal toy example function which sums two numbers
• I then create a test_main.py file with a few banal assertions - one true, one intentionally false.
• If I go back to main.py, place the cursor at the function, right click - goto - test, it correctly takes me to the test I have just written - great
• However, how do I run this test?????
• If I right click on test_main and choose "run test_main", well, it runs the file as though it were a normal file, ie nothing happens - it doesn't run the test like Spyder does!!

After some fiddling, something kinda works if I do Run - edit configuration ; choose + at the top left and choose "Python test - pytest"

But where is this documented? It is incredibly fiddly and inefficient! Do I have to do this every time? Isn't there a more automated way to tell PyCharm to run all the test?

Also, is there a more "graphical" output, something more similar to the Spyder screenshot above, or is the screenshot below all one can get with PyCharm?
