Practice - 5 Tasks

easy

Complete the code to create a custom expected condition that waits for an element to be visible.

Selenium Python

class element_visible:
    def __init__(self, locator):
        self.locator = locator

    def __call__(self, driver):
        element = driver.find_element(*self.locator)
        return element if element.is_displayed() [1] None

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'if' instead of 'or' causes syntax errors.

Returning the element without checking visibility.

Returning True/False instead of element or None.

The 'or' operator returns the element if it is displayed; otherwise, it returns None, which is the expected behavior for a custom expected condition.

Complete the code to define a custom expected condition that waits for the page title to contain a specific word.

Selenium Python

class title_contains_word:
    def __init__(self, word):
        self.word = word

    def __call__(self, driver):
        return self.word in driver.title [1] False

💡 Hint

Common Mistakes

Using 'or False' which always returns True.

Returning the expression without ensuring a boolean result.

Using 'if' or 'else' incorrectly in a return statement.

Using 'and False' ensures the expression returns True if the word is in the title, otherwise False, which is required for expected conditions.

Fix the error in the custom expected condition that waits for an element's text to equal a given value.

Selenium Python

class text_to_be_equal:
    def __init__(self, locator, text):
        self.locator = locator
        self.text = text

    def __call__(self, driver):
        element = driver.find_element(*self.locator)
        return element.text == self.text [1] element

💡 Hint

Common Mistakes

Using 'or element' which returns element even if text does not match.

Returning True/False instead of element or False.

Using 'if' or 'else' incorrectly in return.

Using 'and element' returns the element if the text matches, otherwise returns False, which is the expected behavior for expected conditions.

Fill both blanks to create a custom expected condition that waits for an element to be clickable.

Selenium Python

from selenium.webdriver.support import expected_conditions as EC

class element_to_be_clickable_custom:
    def __init__(self, locator):
        self.locator = locator

    def __call__(self, driver):
        element = driver.find_element(*self.locator)
        return element.is_enabled() [1] element.is_displayed() [2] element

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'or' which returns element if only one condition is true.

Using 'if' or 'else' in return statement.

Returning True/False instead of element or None.

Both conditions must be true for the element to be clickable, so 'and' is used to combine them and return the element if true.

5fill in blank

hard

Fill all three blanks to create a custom expected condition that waits for an element's attribute to have a specific value.

Selenium Python

class attribute_value_is:
    def __init__(self, locator, attribute, value):
        self.locator = locator
        self.attribute = attribute
        self.value = value

    def __call__(self, driver):
        element = driver.find_element(*self.locator)
        attr_value = element.get_attribute([1])
        return attr_value == [2] [3] element

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using wrong variable names for attribute or value.

Using 'or' which returns element even if values don't match.

Returning True/False instead of element or None.

We get the attribute using self.attribute, compare it to self.value, and use 'and' to return the element if the condition is true.
