尝试通过Selenium清除文本时发生InvalidElementStateException

selenium

我正在测试的Web应用程序在删除记录时需要确认。

我创建了一个测试，以输入删除此记录的有效理由。

执行此操作的代码如下：

DeleteFieldButton.
            Click();
        WaitMethods.WaitForElementToBeDisplayed(RemovalReason, 20);
        RemovalReason
            .Click();
        RemovalReason
            .Clear();
        RemovalReason
            .SendKeys("Automated Test - Delete Field");

文本框的XPath如下：

private Label RemovalReason = new Label(By.XPath("//*[@placeholder = 'Removal reason']"));

每当运行测试时，都会返回以下异常。

OpenQA.Selenium.InvalidElementStateException
HResult=0x80131500
Message=Cannot clear By.XPath: //*[@placeholder = 'Removal reason'] as it is 
not declared as a writable text element
Source=web
StackTrace:
at web.Elements.Common.Element.Clear()
at Daera.Efs.Test.E2e.PageObjects.ApplicationSummary.DeleteField(String 
FieldIDToDelete) in 
C:\Code\Local\WebApp.E2e\PageObjects\ApplicationSummary.cs:line 280
 at Test.E2e.Tests.ApplicationSummaryTest.Delete_Wider_General_Field_From_Application_Summary() in C:\Code\Local\WebApp.E2e\Tests\ApplicationSummaryTest.cs:line 45

以下是Web应用程序上元素的HTML：

<input ng-keypress="dialog.keypress($event)" md-autofocus="" ng-model="dialog.result" placeholder="Removal reason" class="ng-valid md-input ng-not-empty md-autofocus ng-touched ng-dirty ng-valid-parse" aria-label="Removal reason" id="input_22" aria-invalid="false" style="">

按照该HTML已经共享了<input>与元素placeholder 属性为 删除的原因 是角
元素，因为你必须发送短信，你必须诱使 WebDriverWait 的 元素可以点击 如下：

IWebElement myElem = new WebDriverWait(driver, TimeSpan.FromSeconds(10)).Until(ExpectedConditions.ElementToBeClickable(By.XPath("//input[@class='ng-valid md-input ng-not-empty md-autofocus ng-touched ng-dirty ng-valid-parse' and starts-with(@id,'input_') and @placeholder='Removal reason']")));
myElem.Click();
myElem.Clear();
myElem.SendKeys("Automated Test - Delete Field");
