cannnot在下拉測試重點元素

Question

這是我在角

<div class="form-group"> 
<label>Select Entity:</label> 
<select class="form-control" id="sel1"> 
<option value="Select">Select</option> 
<option value="Test">Test</option> 
</select> 
</div> 

量角器測試用例下拉菜單是這樣的：

Failed: unknown error: cannot focus element

Answer 1

var entity = element(by.id('sel1')).click(); 
var option = element(by.cssContainingText('option', 'Test')).click(); 

：在量角器

var entity = element(by.id('sel1')).click(); 
var option = element(by.tagName('option[value="Test"]')).click(); 

我收到錯誤
