[英]How to run 'window' js command in nightwatch js
Please i have some tests that varies depending on my device. 请我根据我的设备进行一些测试。 I have to determine whether my device is mobile or desktop before beginning of a test.
在开始测试之前,我必须确定我的设备是移动设备还是桌面设备。
I wanted to exploit the nightwatch before function and i added below in my globals.js 我想在功能之前利用夜视仪,我在我的globals.js中添加了下面的内容
var self = module.exports = {
environment: undefined,
beforeEach: function (done) {
self.environment = browser.window.navigator.userAgent;
console.log("Run against: " + self.environment);
done();
},
};
and i my test 我是我的考试
module.exports = {
tags: ['assetindex'],
'visit': function(browser) {
(/Mobile/.test(browser.globals.environment)) ?
browser
.page.assetindex().mobileVisit()
.end()
:
browser
.page.assetindex().mobileVisit()
.end()
}
};
However, my code failed at 但是,我的代码失败了
self.environment = browser.window.navigator.userAgent;
saying widnow not defined. 说widnow没有定义。 The error makes sense considering i am not running against a browser object .
考虑到我没有针对浏览器对象运行,错误是有道理的。 Please how do i achieve that?
请问我该如何实现? How can i the js window against my browser in nightwatch ?
我怎么能在夜视仪上对着我的浏览器使用js窗口? Any help or alternative is highly appreciated
任何帮助或替代方案都非常感谢
update 更新
After reading the answer below, i update my global.js to 阅读下面的答案后,我将我的global.js更新为
var self = module.exports = {
environment: undefined,
beforeEach: function (browser, done) {
browser.execute(function(data) {
return window.navigator.userAgent;
}, [], function(result) {
console.log('it comes here ', result);
self.environment = result.value;
});
console.log("Run against: " + self.environment);
done();
},
};
TO my surprise, self.environment is always undefined. 令我惊讶的是,自我环境总是未定义的。 It does not seem to be running the .exec function.
它似乎没有运行.exec函数。
You can probably use the execute
command: 您可以使用
execute
命令:
browser.execute(function(data) {
return window.navigator.userAgent;
}, [], function(result) {
self.environment = result.value;
});
For more information: http://nightwatchjs.org/api/execute.html 有关更多信息,请访问: http : //nightwatchjs.org/api/execute.html
In your case, when using beforeEach
you need to move the done()
inside the callback function, like so: 在你的情况下,当使用
beforeEach
你需要在回调函数中移动done()
,如下所示:
beforeEach: function (browser, done) {
browser.execute(function(data) {
return window.navigator.userAgent;
}, [], function(result) {
console.log('it comes here ', result);
self.environment = result.value;
console.log("Run against: " + self.environment);
done();
});
},
