如何通过 Selenium 和 Webdriver 提高执行速度

Question

在不知道原因的脚本执行过程中测试很慢。

这是我的脚本：

driver.Navigate().GoToUrl(url);       
driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(20);
driver.FindElement(By.LinkText("Register Here")).Click();
new WebDriverWait(driver, TimeSpan.FromSeconds(10)).Until(
    SeleniumExtras.WaitHelpers.ExpectedConditions.InvisibilityOfElementLocated(
        (By.XPath("//div[@class='loader-wrapper    ng-trigger ng-trigger-visibilityChanged ng-animating']"))));
driver.FindElement(By.XPath("(.//*[normalize-space(text()) and    normalize-space(.)='Organization    Type'])[2]/following::select[1]")).Click();
new SelectElement(driver.FindElement(By.XPath("(.//*[normalize-space(text())    and normalize-space(.)='Organization    Type'])[2]/following::select[1]"))).SelectByText("Hospital");
driver.FindElement(By.XPath("(.//*[normalize-space(text()) and    normalize-space(.)='Organization    Type'])[2]/following::button[1]")).Click();
new WebDriverWait(driver, TimeSpan.FromSeconds(10)).Until(
    SeleniumExtras.WaitHelpers.ExpectedConditions.InvisibilityOfElementLocated(
        (By.XPath("//div[@class='loader-wrapper    ng-trigger ng-trigger-visibilityChanged ng-animating']"))));
driver.FindElement(By.XPath("(.//*[normalize-space(text()) and    normalize-space(.)='Phone    Number'])[1]/following::button[1]")).Click();
new WebDriverWait(driver, TimeSpan.FromSeconds(10)).Until(
    SeleniumExtras.WaitHelpers.ExpectedConditions.InvisibilityOfElementLocated(
        (By.XPath("//div[@class='loader-wrapper    ng-trigger ng-trigger-visibilityChanged ng-animating']"))));

try
{
    Assert.AreEqual("Title is Required.", driver.FindElement(By.XPath("(.//*[normalize-space(text()) and    normalize-space(.)='Title'])[1]/following::span[1]")).Text);
}
catch (Exception e)
{
    verificationErrors.Append(e.Message);
}

有什么建议可以加快测试速度吗？

Answer 1

让您的脚本/程序更快的一个简单步骤是：

• 将 ImplicitWait 的所有实例删除为：
  • 您正在广泛使用 WebDriverWait，即 Explicit Wait

根据Explicit and Implicit Waits的文档：

警告：不要混合隐式和显式等待。这样做会导致不可预测的等待时间。例如，设置 10 秒的隐式等待和 15 秒的显式等待，可能会导致 20 秒后发生超时。
