WebDriver，Selenium2-简单测试失败

Question

I try this test:

@Test
public void theUserShouldBeAbleToTypeInQueryTerms() {
    WebDriver driver = new FirefoxDriver();
    driver.get("http://www.google.com");
    WebElement queryField = driver.findElement(By.name("q"));
    queryField.sendKeys("cats");
    queryField.submit();
    assertThat(driver.getTitle(), containsString("cats"));
}

but got an error:

Failure, Expected: a string containing "cats" got: "Google"

How can I modify the test to have SUCCESS ?

Answer 1

You have to use WebDriverWait class. It will wait until title will be equals "cats" or timeout. Here's an example of how it works (but you have to adjust the code for your case):

    public static void waitForTitle(final PageTitle title, WebDriver driver) {
    new WebDriverWait(driver, TestDriver.WAIT_TIMEOUT).until(new Function<WebDriver, WebElement>() {

        public WebElement apply(WebDriver driver) {
            for (WebElement we : PageHelper.findElements(WebElementLocator.pageHeader, driver)) {
                if (we.getText().equals(title.getValue())) {
                    return we;
                }
            }
            throw new NoSuchElementException("Title not found: \"" + title.getValue() + "\"");
        }
    });
}
