有时候可能因为被测web的原因导致如下报错：

Uncaught SyntaxError: Unexpected identifier
    
    This error originated from your application code, not from Cypress.
    
    When Cypress detects uncaught errors originating from your application it will automatically fail the current test.
    
    This behavior is configurable, and you can choose to turn this off by listening to the 'uncaught:exception' event.

然而官方也没给出啥解决方案

在support/index.js中添加以下代码：

Cypress.on('uncaught:exception', (err, runnable) => {
      return false
    })

问题解决
