How to check for a change in the Inner Text of an html

Question

I have to check if a change was done in the inner text of an area on my website.

Lets assume this to be the html of such page:

<span _ngcontent-c1="" class="image">
   <span _ngcontent-c1="" style="font-weight: 700">test</span>
        "Question"
   <sup _ngcontent-c1="" class="supR">®</sup></span>

I have this to find the element:

IWebElement testText= driver.FindElement(By.Class("image")).Text;

After clicking on an item in the page, the inner text "Question" changes to "Answer", for example.

What is the best way to check the change? Create a new IWebElement and compare it (with an assertion) to the first one? This is the only way I know. Although, I would like to know if there is a better way. Because in case the inner Text changes with other actions, I don't think creating a new IWebElement every time to check if the change was made.

Answer 1

IWebElement element = driver.FindElement(By.Id("element-id"));

WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));
wait.Until(ExpectedConditions.TextToBePresentInElement(element, "text"));

use webdriver wait :https://www.lambdatest.com/blog/explicit-fluent-wait-in-selenium-c/
