org.openqa.selenium.TimeoutException：预期条件失败：等待 By.xpath 所在元素的可见性：

Question

我正在尝试使用 sendkeys() 选项发送文本。这是我的 class 页面对象中的方法案例：

public void setEntityName() {
    internalWait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*[@id=\"entity_name\"]")));
    entityName.clear();
    entityName.sendKeys("TEST");
}

HTML:

 <input id="entity_name" name="entity_name" type="text" ng-model="entityData.name" ng-disabled="false" placeholder="Type Enity Name" data-maxlength="20" data-smart-validate-input="" data-required="" class="ng-pristine ng-invalid ng-invalid-required ng-valid-maxlength ng-touched">

测试显示错误

org.openqa.selenium.TimeoutException: Expected condition failed: waiting for visibility of element located by By.xpath: //*[@id="entity_name"]

谁能帮我解决这个错误。

所需元素是 Angular 元素，因此要调用 sendKeys() 而不是 visibilityOfElementLocated()，您必须为 [=] 引入 WebDriverWait 14=] 并且您可以使用以下任一解决方案：

使用cssSelector:

public void setEntityName() {
    WebElement entityName = new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("input.ng-pristine.ng-invalid.ng-invalid-required.ng-valid-maxlength.ng-touched#entity_name[ng-model='entityData.name']")));
    entityName.clear();
    entityName.sendKeys("TEST");
}

使用xpath:

public void setEntityName() {
    WebElement entityName = new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//input[@class='ng-pristine ng-invalid ng-invalid-required ng-valid-maxlength ng-touched' and @id='entity_name'][@ng-model='entityData.name']")));
    entityName.clear();
    entityName.sendKeys("TEST");
}
