失败：无法读取的不确定

Question

财产“findElementsOverride”我有如下的测试：

 it('diplays the currency and description of a valid account', function() { 
      common.setValueForInput("CH3809000000911058770", page.inputs.css.zahlungKontoIban).then(
       function() { 
        return element(page.buttons.empfaengerKontoValidieren).click(); 
       }) 
       .then(function() { 
        return expect(element(by.id("zahlungKontoIbanFehler")).isDisplayed()) 
         .toBeFalsy('an error message must not be shown when the accounts are different'); 
       }) 
       .then(function(){ 
        browser.pause(); 
       expect(element(by.id("zielwaehrung")).getAttribute("innerHTML")) 
        .toContain('CHF', 'the currency for CH3809000000911058770 is CHF') 
       expect(element(by.id("empfaengerName")).getAttribute("innerHTML")) 
        .toContain('Test Bezeichnung 2', 'the description for CH3809000000911058770 is Test Bezeichnung 2') 
       }) 
     }); 

它失败的堆栈跟踪：

位置线94:59是语句getInnerHtml()的

expect(element(page.zielwaehrung).getInnerHtml()) 
         .toContain('CHF', 'the currency for CH3809000000911058770 is CHF') 

我把browser.pause()检查确实存在的元素和他们是。

这条消息是什么意思，我该如何调试它？

Answer 1

这个错误来自太多beforeAll电话

我误以为beforeAll应用于describe在调用它。事实证明情况并非如此，当你拨打beforeAll 5个电话时，其中browser.get会发出一些信息。

我用一次呼叫替换了多个呼叫到beforeEach，现在一切正常。

Answer 2

getInnerHtml方法现在不推荐使用，而是使用getAttribute("innerHTML")代替。
