Nightwatch中的setValue方法不起作用

问题描述

我正在尝试设置一个新的Nightwatch项目，以实现简单的Google搜索页面的自动化.我对页面上出现的 searchbox 的断言通过了，但是我无法对元素(Searchbox或SearchButton)

I am trying to setup a new Nightwatch project for the purpose of automating a simple Google search page. My assert for searchbox present on page passes, but I am not able to perform any mouse/keyboard action on the elements (Searchbox, or SearchButton)

注意::我正在运行Nightwatch版本1.0.

Note: I am running Nightwatch version 1.0.

测试用例:

module.exports = {
  before : function(browser) {
   browser.globals.waitForConditionTimeout = 5000;
  },
    tags: ['google'],
    'Demo test Google' : function (browser) {
         browser 
         .url('http://www.google.com') // Go to a url
         .waitForElementVisible('body', 10000) // wait till page loads
         .pause(2000)
         .assert.title('Google') // Make sure Site title matches
         .assert.visible('input[name=q]') 
         .setValue('input[name=q]', 'nightwatchjs') // send values
         .click('button[name=btnG]') // click on search box
         .pause(1000)
         .end()
       },
};

我也尝试过这种方法:

var setValue =  function(sel, value) {
  $(sel).val(value).change();
};

module.exports = {
  before : function(browser) {
       browser.globals.waitForConditionTimeout = 5000;
  },
    tags: ['google'],
    'Demo test Google' : function (browser) {
         browser 
         .url('http://www.google.com') // Go to a url
         .waitForElementVisible('body', 10000) // wait till page loads
         .pause(2000)
         .assert.title('Google') // Make sure Site title matches
         .assert.visible('input[name=q]') 
         .execute(setValue, ['input[name=q]', 'nightwatchjs'])
         .click('button[name=btnG]') // click on search box
         .pause(1000)
         .end()
       },
};

这是输出日志:

运行:对Google进行演示测试

Running: Demo test Google

• √元素在133毫秒后可见.
• √测试页面标题是否等于"Google"-18毫秒.
• √测试元素是否可见-61毫秒.

推荐答案

尝试先在输入上单击click()，然后再使用setValue()，有时会有所帮助

Try to click() on input first, and then use setValue(), sometimes it helps
