The pys fixture is used if you want a single instance of Pylenium that is shared across all tests within a Test Session.
Using py is the recommended way of working with Pylenium. Sharing data and states across tests is a bad practice. For example, you cannot run tests in parallel in this mode.
Import Pylenium and add the type hint to your tests (as shown above) so you get intellisense and autocomplete when writing tests
Arguments
none
Yields
Pylenium - an instance of Pylenium driver that interacts with the web
pys_config
When using pys, an instance of PyleniumConfig is also created and can be managed for the test session. You can access pys_config as a fixture or directly from pys.config
Access by Fixture
from pylenium.driver import Pylenium
from pylenium.config import PyleniumConfig
class TestSauceDemo:
def test_land_on_products_page_after_login(self, pys: Pylenium, pys_config: PyleniumConfig):
pys_config.custom["user"] = "standard_user" # Set a value in one test...
pys.visit("https://www.saucedemo.com/")
pys.get("#user-name").type("standard_user")
pys.get("#password").type("secret_sauce")
pys.get("#login-button").click()
assert pys.contains("Products").should().be_visible()
def test_add_item_to_cart_increments_counter_by_1(self, pys: Pylenium, pys_config: PyleniumConfig):
print(pys_config.custom.get("user")) # And use it in another test
pys.get("[id*='add-to-cart']").click()
assert pys.get("a.shopping_cart_link").should().have_text("1")
Access Directly (recommended)
Recommended because it's fewer lines of code and you already have access via Pylenium
from pylenium.driver import Pylenium
class TestSauceDemo:
def test_land_on_products_page_after_login(self, pys: Pylenium):
pys.config.custom["user"] = "standard_user" # Set a value in one test...
pys.visit("https://www.saucedemo.com/")
pys.get("#user-name").type("standard_user")
pys.get("#password").type("secret_sauce")
pys.get("#login-button").click()
assert pys.contains("Products").should().be_visible()
def test_add_item_to_cart_increments_counter_by_1(self, pys: Pylenium):
print(pys.config.custom.get("user")) # And use it in another test
pys.get("[id*='add-to-cart']").click()
assert pys.get("a.shopping_cart_link").should().have_text("1")
