硒可访问性测试

Question

我已经下载了最新的 rcx 文件，并在 chrome 选项中添加了扩展。

第一步执行得很好。第二步执行到 driver.Navigate().GoToUrl("chrome://extensions-frame/");

下一步它会抛出这个错误

"OpenQA.Selenium.NoSuchElementException

我正在使用“extension_1_0_9_0.crx”作为当前扩展名。

请满足需要。

我的代码如下：

[TestInitialize]
        public void Init()
        {
            //Open ChromeDriver with appropriate extension enabled
            ChromeOptions options = new ChromeOptions();
            options.AddExtension("../Extension/extension_1_0_9_0.crx");
            driver = Driver.Initalize<ChromeDriver>(options);
        }
    [TestMethod]
    public void AccessabilityTest()
    {
        // 2 - setup key shortcut for extension
        driver.Navigate().GoToUrl("chrome://extensions-frame/");
        driver.FindElement(By.XPath("//a[@class='extension-commands-config']"))
            .Click();
        driver.FindElement(By.XPath("//span[@class='command-shortcut-text']"))
            .SendKeys(Keys.Control + "m");
        driver.FindElement(By.Id("extension-commands-dismiss"))
            .Click();

        // 3
        driver.Navigate().GoToUrl("http://www.google.pl");
        // 4 - open WAVE extension 
        new Actions(driver).KeyDown(Keys.Control).SendKeys("m").Build().Perform();

        // 5
        var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));
        wait.Until(ExpectedConditions.ElementExists(By.ClassName("wave5icon")));

        // 6
        var waveTips = driver.FindElements(By.ClassName("wave5icon"));
        if (waveTips.Count == 0) Assert.Fail(
            "Could not locate any WAVE validations - " +
            "please ensure that WAVE is installed correctly");
        foreach (var waveTip in waveTips)
        {
            if (!waveTip.GetAttribute("alt").StartsWith("ERROR")) continue;

            var fileName = String.Format("{0}{1}{2}",
                "WAVE", DateTime.Now.ToString("HHmmss"), ".png");
            var screenShot = ((ITakesScreenshot)driver).GetScreenshot();
            //screenShot.SaveAsFile(
            //    Path.Combine(System.IO.Path.GetTempPath(), fileName), ImageFormat.Png);
            driver.Close();
            Assert.Fail(
                "WAVE errors were found on the page. Please see screenshot for details");
            Assert.IsTrue(false, "One or more of the functionality tests failed : WAVE errors were found on the page. Please see screenshot for details");
        }

        //Assert.IsTrue(isAllPass, "One or more of the functionality tests failed");
    }

Answer 1

2 件事。他们已移动链接以启用 Chrome 插件的快捷键。您甚至可以通过手动切换其中任何一个来看到这一点。该选项仍然可用@ chrome://extensions，但它不再位于页面底部，它是用户 id=menuButton。

我还认为，即使您启用了该选项，将 CTRL+m 发送到浏览器也会遇到问题。

Answer 2

为了回答问题中的任何行都可以，我使用的是带有 WAVE 扩展的那些行，这就是问题所在。

我没有尝试使用 Wave 实现此功能的任何方法。它不适用于 wave 只会为您提供错误的快照。

从快照中，您将无法了解哪些是错误或缺陷的类型。 我建议不要为可访问性测试使用 WAVE 扩展。而不是使用工具“Globant.Selenium.Axe”。使用 Nuget 包管理器

安装插件

这是 Chrome 扩展程序的 link。

这是在文本文件中记录错误的代码：

 //If file does not exists, Create a new file and log the result.
            if (!File.Exists(accessiblityTestFileLocation))
            {
                File.Create(accessiblityTestFileLocation).Dispose();
                LogResult ();
            }
            //If file exists, Log the result into file.
            else if (File.Exists(accessiblityTestFileLocation))
            {
                LogResult ();
            }

日志结果函数：

   public void LogResult ()
                {

     using (StreamWriter sw = new StreamWriter(accessiblityTestFileLocation))
        {
            foreach (var path in appInfo.Pages)
            {
                var navigateUrl = new Uri(baseUrl, path.Path);

                driver.Navigate().GoToUrl(navigateUrl);
                driverService.driver.Manage().Window.Maximize();

                AxeResult results = driver.Analyze();

                //Format the results, And write them in the text file.
                if (results.Passes.Length > 0)
                {
                    //Format the text as per your need, This text will be entered into the Text file.
                    sw.WriteLine("\n");
                    sw.WriteLine(path.Title);
                    sw.WriteLine("===========================");
                    sw.WriteLine("\n");

                    foreach (var passCase in results.Passes)
                    {
                        sw.WriteLine("Id: " + passCase.Id);
                        sw.WriteLine("Description: " + passCase.Description);
                        sw.WriteLine("Impact: " + "Normal");
                        sw.WriteLine("Help: " + passCase.Help);
                        sw.WriteLine("HelpURL: " + passCase.HelpUrl);
                        foreach (var node in passCase.Nodes)
                        {
                            sw.WriteLine(node.Html);
                            sw.WriteLine("\n");
                        }
                    }
                }

                //Format the results based on the result type, And write them in the text file.
                if (results.Violations.Length > 0)
                {
                    foreach (var violation in results.Violations)
                    {
                        //Write the accessibility test for the selected Attributes provided by the Axecore.
                        sw.WriteLine("Id: " + violation.Id);
                        sw.WriteLine("Description: " + violation.Description);
                        sw.WriteLine("Impact: " + violation.Impact);
                        sw.WriteLine("Help: " + violation.Help);
                        sw.WriteLine("HelpURL: " + violation.HelpUrl);
                        foreach (var node in violation.Nodes)
                        {
                            sw.WriteLine(node.Html);
                            sw.WriteLine("\n");
                        }
                    }
                }
            }
        }
                }
