parameter is required by @ Test but has not been marked @optional or defined

Question

Hi I am seeing this error, please help

Parameter 'Visit' is required by @Test on method searchByVisitNo but has not been marked @Optional or defined.

I don't know why is there a need to mark it optional when it is defined in testng xml file

Here is the entire code I used

<suite name="Suite" parallel="tests">
    <test name="SearchByVisit">
        <parameter name="Visit" value="123456"/>
        <classes>
            <class name="abc"/>
        </classes>
    </test>
</suite>

@Parameters({"Visit"})
@Test(priority=3)
public void searchByVisitNo(String VisitNumber)throws InterruptedException
{
    searchByVisit(VisitNumber);
}

public void searchByVisit(String Visit) throws InterruptedException
{
    WebDriverWait wait = new WebDriverWait(driver, 20);
    WebElement element = wait.until(
        ExpectedConditions.visibilityOfElementLocated(By.id("search-input"))
    );
    element.sendKeys(Visit);
    clickSearch();
}

You are passing paramter <parameter name="Visit" value="123456"/> in your .xml file and you directly running your TestNG class. So it's not getting that parameter while compiling .

So you need to run your xml suite to provide a valid parameter to your TestNG class.
