WebDriver getText 抛出异常

Question

Okay, I am completly clueless: I have table on the page where every rows has CSS ID incremented by one. And I am searching the Auction ID in such table and matching it with the Auction I entered through previous Selenium test. So my code goes like this:

    int i = 0;
    Boolean stillHaveSomethingToSearch = true;
    Boolean foundit = false;

    while (stillHaveSomethingToSearch){
        idConstructor = "mainForm:aucPanelId:0:listOfAuctions:"+i;

        try{
            auctionRow = driver.findElement(By.id(idConstructor));
        } catch (NoSuchElementException e){
            stillHaveSomethingToSearch = false;
        }
        if (stillHaveSomethingToSearch) {
           foundAuctionID = auctionRow.getText();
            System.out.println("foundAuctionID = " + foundAuctionID);
           if (auctionID.equals(foundAuctionID)){
               stillHaveSomethingToSearch = false;
               foundit = true;
           }
        }
        i++;
    }
    if (foundit){
        auctionRow.click();
     }

Where "auctionID" is send to the method by previous test.

auctionRow is Webelement represented with two spans where the actual auctionID is stored

  <span id="mainForm:aucPanelId:0:listOfAuctions:0">116</span>

Whole row is clickable, so after i send the click() command, it will open me found auction

What is strange: The auctionRow.getText(); throws an error.

If i change it to getTagName() function it will correctly return me "span"

How do I force it to provide me the text between two spans?

SOLVED Ok, I found nice and easy (and shorter to code) workaround. Since I know that the Auction ID is in span element an I know what the ID should be, I am now searching by Xpath:

public AuctionTab showAuctionID(String auctionID){
    try{
     auctionRow = getRegulationUI().getDriver().findElement(By.xpath("//span[text()='"+auctionID+"']"));
    }catch (NoSuchElementException e){
        throw new NotFoundException("Auction ID "+ auctionID+ "was not found on first page");
    }
    auctionRow.click();
    return new AuctionTab(this);
    }

Answer 1

Instead of doing this:

getDriver().findElement(By.xpath("//span[text()='"+auctionID+"']"));

I would try something like this:

By auctionList = By.xpath(".//span[contains(@id,'listOfAuctions')]"));
By containsTextWithId = By.xpath(".//span[contains(.,'" + id + "')]"));
By combinedLocator = new ByChained(auctionList, containsTextWithId);

Or some similar idea, depending on what you are doing.

Answer 2

Instead of using getText(), in many occasions it's better to call getValue(). Using the getValue you might get a longer string, but the text you are expecting inside should be there.
