@given("nopcommerce page is displayed")
def webpage(browser):
    browser.get("http://admin-demo.nopcommerce.com")

@when("user enters username as admin@yourstore.com")
def enter_uname(browser):
    browser.find_element_by_id("Email").send_keys("admin@yourstore.com")

@when("user enters password as admin")
def enter_pwd(browser):
    browser.find_element_by_id("Password").send_keys("admin")

Answer 1

It's not entirely the solution, and I have the same issue in PycharmIDE, but I suggest using terminal and start tests like:

pytest <test_fily.py>

for IDEA solution, still working on it

Answer 2

I guess the problem is that the pytest is not identifying any executable pytest method's in your step definition file. Please try changing the "scenarios" to "scenario" and add a pytest identifiable method below the same

@scenario('../features/NopcommerceLogin.feature')
def test_login():
      pass

This approach always works for me and is based on Pytest-BDD doc.

Answer 3

Change your configurations to use pytest configuration: screenshot

or try running using terminal : pipenv run python -m pytest

Answer 4

Make sure that pytest configured in pycham Enable Pytest for your project

Open the Settings/Preferences | Tools | Python Integrated Tools settings dialog as described in Choosing Your Testing Framework. In the Default test runner field select pytest. Click OK to save the settings

Answer 5

@Vova I found that in the run configuration, the Working directory was incorrectly set to the directory where the steps python file was, instead of the project root directory. Fixing that made the test run successfully in PyCharm.

Answer 6

I had this issue - it was simply alignment in the feature file, I had a space on the Scenario definition after 'Scenario' and before the colon. When I removed - the error no longer occured.
