How can I specify the number of elements that test positive for the locator I'm using?

Question

In Selenium when waiting for an element to load how can I specify the number of elements that test positive for the locator I'm using?

This is my case, I want to check for a div of class 'classA' which contains a text 'text2':

WebDriverWait(driver,3)
    .until(expected_conditions
        .text_to_be_present_in_element(
            (By.CLASS_NAME, 'classA'), 'text2'))

but this is going to time out with however long a wait I set, while the previous element also with 'classA' but with 'text1' is found without issue.

I think Selenium is locating the previous element based on class, than testing if its text ever changes to 'text2'.

I want to find the second element based on class, then test for its text (note that presence_of_all_elements_located will return as soon as it founds a single positive).

Answer 1

You can achieve this with custom wait condition using lambda. For example, in case you want to wait 3 seconds until number of elements will be equal 2:

WebDriverWait(driver,3)
   .until(lambda method: len(driver.find_elements(By.CLASS_NAME, 'className')) == 2)

Answer 2

You can not do it with existing built-in methods in Python.
In Java we have expected conditions like

wait.until(ExpectedConditions.numberOfElementsToBe(element, expectedElementsAmount));

and

wait.until(ExpectedConditions.numberOfElementsToBeMoreThan(element,expectedElementsAmount));

but these methods are missing in Python.
You can implement such custom methods by yourself in Python
