在量角器中按值选择选项失败

我试图按选项值选择一个选项。在这种情况下，我有类别和子类别。这是我使用量角器测试的应用程序。在量角器中按值选择选项失败

这里就是我做的是首先添加的类别。我必须刷新页面，因为只有在刷新页面时，添加的类别才会列在子类别选项卡中显示的类别下拉列表中。所以，刷新页面后，我点击子类别选项卡，并尝试填充子类别中的字段。但是，从选项中选择类别时，我的脚本失败。

以下是我尝试的两种方法。

方法1：

// Select Category 
element.all(by.model('sub_category.category_id')).each(function (eachElement, index) 
{ 
    eachElement.click(); 
    browser.driver.sleep(500); 
    element(by.css('.ng-not-empty > option:nth-child(10)')).click(); 
    browser.driver.sleep(500); 
});

方法2：

var select = element(by.model('sub_category.category_id')); 
select.$('[value="Test Supplier Category by Me"]').click(); 
browser.driver.sleep(500);

两种方法都给出了所谓的错误，

失败：使用定位器没有的元素中找到...

下面是HTML

<select required="required" class="form-control empty ng-pristine ng-empty ng-invalid ng-invalid-required ng-touched" name="category_id" ng-model="sub_category.category_id" ng-options="category.id as category.category for category in categories_index" ng-required="true"><option selected="selected" value="?"></option><option value="string:6" label="Staff Cost">Staff Cost</option><option value="string:7" label="Utility Bill Expenses">Utility Bill Expenses</option><option value="string:8" label="Administrative Expenses">Administrative Expenses</option><option value="string:9" label="Building Rent">Building Rent</option><option value="string:10" label="Professional Charges &amp; Fees">Professional Charges &amp; Fees</option><option value="string:11" label="Vehicle Expenses">Vehicle Expenses</option><option value="string:13" label="Training &amp; Workshop Cost">Training &amp; Workshop Cost</option><option value="string:14" label="Marketing &amp; Promotional Expenses">Marketing &amp; Promotional Expenses</option><option value="string:15" label="Printing &amp; Supplies">Printing &amp; Supplies</option><option value="string:16" label="Fixed Assets">Fixed Assets</option><option value="string:17" label="Finance Cost">Finance Cost</option><option value="string:18" label="Statutory Payments">Statutory Payments</option><option value="string:19" label="Overseas Travelling Expenses">Overseas Travelling Expenses</option><option value="string:20" label="Test Supplier Category By Me">Overseas Travelling Expenses</option></select>

当我使用梅托德1，会出现以下错误。

您能否提供您正在使用的'select'元素的HTML表示？截图在这里没有多大帮助。此外，发布错误的完整回溯。谢谢。 – alecxe

@alecxe，已添加。你能看一下吗？:) –

首先，我没有看到张贴的HTML的Test Supplier Category by Me选项。

另外，看起来您正在检查value属性，但应该检查选项的文本。这可以用XPath定位器来完成：

element(by.xpath("//option[. = 'Utility Bill Expenses']")).click();

但是，我真的会考虑使用这里提出一个Select包装：

Select -> option abstraction

然后，代码将如此简单：

var SelectWrapper = require('select-wrapper'); 
var mySelect = new SelectWrapper(by.model('sub_category.category_id')); 

mySelect.selectByText('Utility Bill Expenses');

这给出了一个错误，称为找不到select-wrapper。 :( –

@QualityProducts很好，当然，因为它是一个单独的'select-wrapper.js'文件，您需要手动创建。请仔细研究该链接线程的答案。 – alecxe
