事实证明,这个问题的解决方案是植根于NgWebDriver
. NgWebDriver 遵循 IE、Edge、PhantomJS、Firefox 和 Safari 的驱动程序来导航到 URL,但如果它是其他任何东西,那么它只是运行这个:this.ExecuteScript("window.name += '" + AngularDeferBootstrap + "'; window.location.href = '" + value + "';");
被调用的JavaScript 方法不仅仅处理传入本地路径,它需要一个 http(s) 字符串来导航。所以能不能传入本地路径,就看具体驱动实现Url属性的set方法了。
以下是相关的Protractor-net属性。
public class NgWebDriver : IWebDriver, IWrapsDriver, IJavaScriptExecutor
{
private const string AngularDeferBootstrap = "NG_DEFER_BOOTSTRAP!";
private IWebDriver driver;
private IJavaScriptExecutor jsExecutor;
private string rootElement;
private IList<NgModule> mockModules;
// constructors and stuff
/// <summary>
/// Gets or sets the URL the browser is currently displaying.
/// </summary>
public string Url
{
get
{
this.WaitForAngular();
return this.driver.Url;
}
set
{
// Reset URL
this.driver.Url = "about:blank";
// TODO: test Android
IHasCapabilities hcDriver = this.driver as IHasCapabilities;
if (hcDriver != null &&
(hcDriver.Capabilities.BrowserName == "internet explorer" ||
hcDriver.Capabilities.BrowserName == "MicrosoftEdge" ||
hcDriver.Capabilities.BrowserName == "phantomjs" ||
hcDriver.Capabilities.BrowserName == "firefox" ||
hcDriver.Capabilities.BrowserName.ToLower() == "safari"))
{
this.ExecuteScript("window.name += '" + AngularDeferBootstrap + "';");
this.driver.Url = value;
}
else
{
this.ExecuteScript("window.name += '" + AngularDeferBootstrap + "'; window.location.href = '" + value + "';");
}
if (!this.IgnoreSynchronization)
{
try
{
// Make sure the page is an Angular page.
long? angularVersion = this.ExecuteAsyncScript(ClientSideScripts.TestForAngular) as long?;
if (angularVersion.HasValue)
{
if (angularVersion.Value == 1)
{
// At this point, Angular will pause for us, until angular.resumeBootstrap is called.
// Add default module for Angular v1
this.mockModules.Add(new Ng1BaseModule());
// Register extra modules
foreach (NgModule ngModule in this.mockModules)
{
this.ExecuteScript(ngModule.Script);
}
// Resume Angular bootstrap
this.ExecuteScript(ClientSideScripts.ResumeAngularBootstrap,
String.Join(",", this.mockModules.Select(m => m.Name).ToArray()));
}
else if (angularVersion.Value == 2)
{
if (this.mockModules.Count > 0)
{
throw new NotSupportedException("Mock modules are not supported in Angular 2");
}
}
}
}
catch (WebDriverTimeoutException wdte)
{
throw new InvalidOperationException(
String.Format("Angular could not be found on the page '{0}'", value), wdte);
}
}
}
}
由于此属性假定应用程序正在使用 Angular,因此在与您一起导航时Navigate().GoToUrl()
必须再次包含应用程序是否通过bool
.
在我们的例子中,我们没有使用 Angular 并将其传递给GoToUrl()
方法调用,直接传递给包装的IWebDriver
via INavigation
。此包装的驱动程序正确处理本地文件。
下面是Protractor-net中的导航类:
public class NgNavigation : INavigation
{
private NgWebDriver ngDriver;
private INavigation navigation;
// irrelevant constructors and such
/// <summary>
/// Load a new web page in the current browser window.
/// </summary>
/// <param name="url">The URL to load. It is best to use a fully qualified URL</param>
/// <param name="ensureAngularApp">Ensure the page is an Angular page by throwing an exception.</param>
public void GoToUrl(string url, bool ensureAngularApp)
{
if (ensureAngularApp)
{
this.ngDriver.Url = url;
}
else
{
this.navigation.GoToUrl(url);
}
}
