Question

我正在尝试在Katalon（使用Groovy）中执行显式等待。我有以下代码：

// wait on page change to "Dashboard"
    WebDriverWait dashboardChangeWait = new WebDriverWait(driver, 3)
    /* This is causing the following Exception : 
     *   - GroovyCastException : Attempt to cast 'true' with class 'java.lang.Boolean' to class
     *      'org.openqa.selenium.WebElement'
     * */
    WebElement element = dashboardChangeWait.until(
        ExpectedConditions.textToBe(By.cssSelector('.breadcrumb-item.active'), "DASHBOARD"))

给了我一个GroovyCastException。我知道WebDriverWait.until需要Function（yay，类似JavaScript的编码！）参数，以及ExpectedConditions.textToBe returns a ExpectedCondition<Boolean>和until的签名是V org.openqa.selenium.support.ui.FluentWait.until(Function<Object, Object<V>> arg0)。有没有办法在Katalon执行这种类型的等待，这可以避免这个问题？

Answer 1

你非常接近。 ExpectedConditions 方法textToBe()定义如下：

public static ExpectedCondition<java.lang.Boolean> textToBe(By locator, java.lang.String value)

An expectation for checking WebElement with given locator has specific text

Parameters:
locator - used to find the element
value - used as expected text

Returns:
Boolean true when element has text value equal to @value

因此，您只需将返回类型更改为 boolean 而不是WebElement，如下所示：

Boolean status = dashboardChangeWait.until(ExpectedConditions.textToBe(By.cssSelector('.breadcrumb-item.active'), "DASHBOARD"))

执行Selenium显式等待时，Katalon中的GroovyCastException
