WebBrick
Make Driver Actions
# PlayWright
from web_bricks import WebBrick
from playwright.async_api import ElementHandle
class WebElement(WebBrick):
async def element(self) -> ElementHandle:
return await self.driver.wait_for_selector(f'xpath={self.full_locator_str}')
async def tap(self):
return await self.element.tap()
async def is_visible(self):
try:
await self.driver.wait_for_selector(f'xpath={self.full_locator_str}', state='visible')
except TimeoutError as e:
return False
return True
@property
async def inner_text(self):
return await self.element.inner_text('value')
Make Page Object Tree Interface
from web_bricks import many
from typing import List
class RootPageSingleElement(WebElement):
LOCATOR = '//*[@data-n="single-element-on-root-page"]'
class RootPageListElements(WebElement):
LOCATOR = '//*[@data-n="element-of-list"]'
class RootPageBlock(WebElement):
LOCATOR = '//*[@data-n="block-on-root-page"]'
@property
def element_of_list(self) -> List[RootPageListElements]:
return many(RootPageListElements(self))
class RootPage(WebElement):
LOCATOR = '/*'
@property
def single_element(self) -> RootPageSingleElement:
return RootPageSingleElement(self)
@property
def block(self) -> RootPageBlock:
return RootPageBlock(self)
Do the things
from web_brick import str_xpath_locator_extractor
with async_playwright() as playwright:
browser = playwright.chromium.lunch()
page = browser.new_page()
# treat LOCATOR as xpath string
app = RootPage(page, config=WebBricksConfig(locator_repr_extractor=xpath_str_locator_extractor)
# Interact with PO
var_zero_elem_value = await app.block.element_of_list[0].inner_text
await app.single_element.tap()
assert await app.block.is_visible()
assert app.block.element_of_list[0].is_visible()
assert app.block.element_of_list[0].inner_text == 'SomeValue'
assert app.block.element_of_list[3].inner_text == var_zero_elem_value
