试图检查的角度plunker此元素的值:如何在量角器测试中找到元素?
it('should display valid',function(){
browser.get('http://embed.plnkr.co/3nt01z/preview');
var errortext =element(By.xpath('body>div>h2>span:nth-child2)')).getText);
expect(errortext).toBe('Not:(');
})
虽然得到一个错误:
Stacktrace:
InvalidSelectorError: invalid selector: Unable to locate an element with the xpath expression body>div>h2>span:nth-child(2) because of the following error:
SyntaxError: Failed to execute 'evaluate' on 'Document': The string 'body>div>h2>span:nth-child(2)' is not a valid XPath expression.
有没有更好的方式来找到这个span元素或什么是正确的XPath表达?
