打开一个新窗口/选项卡

我试图创建一个测试脚本，将通过我的网站，点击一个链接，打开一个新的选项卡到另一个网站，填写表单提交，然后回到原来的网站，但是我看过的每一个例子，并尝试不适合我。页面一直运行，直到它打开新窗口，然后新窗口在那里停留大约5秒钟，然后一切都关闭了。这是我得到的:

var x = require('casper').selectXPath;
casper.options.viewportSize = {width: 1920, height: 1075};
casper.on('page.error', function(msg, trace) {
   this.echo('Error: ' + msg, 'ERROR');
   for(var i=0; i<trace.length; i++) {
       var step = trace[i];
       this.echo('   ' + step.file + ' (line ' + step.line + ')', 'ERROR');
   }
});
casper.test.begin('Resurrectio test', function(test) {
   casper.start('https://mywebsite1/abc/default.asp');
   casper.waitForSelector("form[name=FormSize] input[name='a']",
       function success() {
           test.assertExists("form[name=FormSize] input[name='Nickname']");
           this.click("form[name=FormSize] input[name='Account']");
       },
       function fail() {
           test.assertExists("form[name=FormSize] input[name='Nickname']");
   });
   casper.waitForSelector("input[name='Nickname']",
