Pytest - run multiple tests from a single file

I'm using Pytest (Selenium) to execute my functional tests. I have the tests split across 2 files in the following structure:

My_Positive_Tests.py

class Positive_tests:


  def test_pos_1():
    populate_page()
    check_values()

  def test_pos_2():
    process_entry()
    validate_result()

My_Negative_Tests.py

class Negative_tests:
  def test_neg_1
    populate_page()
    validate_error()

The assertions are done within the functions (check_values, validate_result, validate_error). I'm trying to find a way to run all the tests from a single file, so that the main test file would look something like:

My_Test_Suite.py

test_pos_1() 
test_pos_2()
test_neg_1()

Then from the command line I would execute:

py.test --tb=short "C:\PycharmProjects\My_Project\MyTest_Suite.py" --html=report.html

Is it possible to do something like this? I've been searching and haven't been able to find out how to put the calls to those tests in a single file.

Start file names and tests with either test_ or end with _test.py. Classes should begin with Test

Directory example:
|-- files
|--|-- stuff_in stuff
|--|--|-- blah.py
|--|-- example.py
|
|-- tests
|--|-- stuff_in stuff
|--|--|-- test_blah.py
|--|-- test_example.py

In terminal: $ py.test --cov=files/ tests/ or just $ py.test tests/ if you don't need code coverage. The test directory file path must be in your current directory path. Or an exact file path ofcourse

With the above terminal command ($ py.test tests/), pytest will search the tests/ directory for all files beginning with test_. The same goes for the file.

test_example.py 

# imports here

def test_try_this():   
    assert 1 == 1
# or
class TestThis:
    assert 1 == 0
# or even:
def what_test():
    assert True

You need to change the class name

class Positive_tests: to--> class Test_Positive:

The class name should also start with "Test" in order to be discovered by Pytest. If you don't want to use "Test" in front of your class name you can configure that too, official doc here

You don't have to run your tests manually. Pytest finds and executes them automatically:

# tests/test_positive.py
def test_pos_1():
    populate_page()
    check_values()

def test_pos_2():
    process_entry()
    validate_result()

and

# tests/test_negative.py
def test_neg_1():
    populate_page()
    validate_error()

If you then run 

py.test

They should automatically be picked up.

You can then also select a single file

py.test -k tests/test_negative.py

or a single test

py.test -k test_neg_1
