我目前正在尝试建立一个 Nightwatch 项目，看看它是否有用。我正在关注 This tutorial现在。本教程中的内容有效，但是当我尝试对其进行一些修改时，它不再起作用了。我查看了 Developer API guide ，但我想我还是遗漏了什么？我使用的代码粘贴在下面:
var conf = require('../../nightwatch.conf.js');
module.exports = {
'Demo test' : function (browser) {
browser
.url('http://localhost/myWebsite?newwindow=0')
.waitForElementVisible('body', 6000)
.setValue('input[name=txtLogin]', 'login')
.setValue('input[name=txtPassword]', 'password')
.waitForElementVisible('input.btnLogin', 2000)
.click('button[id=btnLogin]')
.pause(6000)
.assert.elementPresent("#selectTitle")
.assert.containsText('#selectTitle', 'schedules')
.assert.urlContains('login/login_start.asp')
.saveScreenshot(conf.imgpath(browser) + 'titleScreen.png')
.end();
}
};
命令错误:
Running: Demo test
√ Element <body> was visible after 41 milliseconds.
ERROR: Unable to locate element: "input[name=txtLogin]" using: css selector

× Timed out while waiting for element <input.btnLogin> to be present for 2000 milliseconds. - expected "visible" but got: "not found"
at Object.Demo test (C:\Workspace\myWebsite\learn-nightwatch\test\e2e\My_Test.js:10:8)

最后，html 只是为了完成:
<input type="text" class="inputText" id="txtLogin" name="txtLogin" >
<input type="password" class="inputText" id="txtPassword" name="txtPassword" >
最佳答案
setValue 对我来说也很棘手。有时它会输入值但随后会清除它们，目前 (10/10/2017) 每次我使用 setValue 函数时它都会突然打开 Chrome 设置选项卡。
我现在要做的是首先定义一个这样的函数
var setValue = function(sel, value) {
$(sel).val(value).change();
};
然后像那样从 Nightwatch 链函数中调用它
browser.url('https://google.com')
.execute(setValue, ['#search', 'keyword'])
.click('#search-btn')
.waitForElementVisible('an example of selector')
.assert.containsText('selector', '100000xxxx results')
关于javascript - Nightwatch setValue 方法不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/40990894/
