May I know the way to set up an assertion to verify value of an element in Serenity?

Hello Charity,

To set up an assertion to verify value of an element in Serenity, please add the following sample code below:

Assert.AreEqual("Sample page - lambdatest.com", driver.Title);
IWebElement firstCheckBox = driver.FindElement(By.Name("li1"));
            firstCheckBox.Click();

IWebElement secondCheckBox = driver.FindElement(By.Name("li2"));
            secondCheckBox.Click();

IWebElement textfield = driver.FindElement(By.Id("sampletodotext"));
            textfield.SendKeys(itemName);

IWebElement addButton = driver.FindElement(By.Id("addbutton"));
            addButton.Click();

IWebElement itemtext = driver.FindElement(By.XPath("/html/body/div/div/div/ul/li[6]/span"));
String getText = itemtext.Text;
Assert.IsTrue(itemName.Contains(getText));
