API手册

mWebDriver 有3个类: Driver, Broswer, Elements

所有API均支持 链式Promise 和 generator，以及es7 async语法:

browser.find('#kw').then(function(elements){
    return elements.val('test')
                   .submit();
})
.title()
.then(function(title){
    console.log(title);
});

并且，你也可以基于Driver类使用混合链式Promise, 所有API方法都会从Browser和Elements类复制到Driver类的实例上:

var driver = new MWebDriver();

driver.session("chrome")
    .url('https://www.baidu.com/')
    .find('#kw')
    .val('mp3')
    .submit()
    .title()
    .then(function(title){
        console.log(title);
    })
    .close();

你可以下面搜索所有的API，已经包括了所有API的所有使用方式:

如何获取元素的截图？

1. 安装gm组件

   brew install graphicsmagick (Mac)

   sudo apt-get install graphicsmagick (Linux)

   http://www.graphicsmagick.org/download.html (Windows)

2. 获取截图

   var png_base64 = yield browser.getScreenshot({ elem: '#id', filename: 'test.png' });

如何扩展自定义方法？

var MWebDriver = require('mWebDriver');

var driver = new MWebDriver();

MWebDriver.addMethod('searchMp3', function(){
    return this.find('#kw').val('mp3').submit();
});

driver.session("chrome")
    .url('https://www.baidu.com/')
    .searchMp3()
    .title()
    .then(function(title){
        console.log(title);
    })
    .close();
