Selenium IDE 正在停止 javascript

Question

当使用 Selenium IDE 记录网页上的操作时，应用程序正在停止 JavaScript 并显示错误消息 "too much recursion."

我在 FireFox 54.0.1

上使用 Selenium IDE 2.9.1.1

我写了一个简单的 javascript 测试警报，但它也被 Selenium 阻止了。

<html>
<head>
    <script>
        function hello(){
            alert("Hello\nHow are you?");
        }
    </script>
</head>
<body>
    <input type="button" onclick="hello();" value="Say Hi" />
</body>
</html>

enter image description here

selenium-ide/content/recorder.js

Recorder.prototype.reattachWindowMethods = function() {
   var window = this.getWrappedWindow();
   //this.log.debug("reattach");
   if (!this.windowMethods) {
       this.originalOpen = window.open;
   }
   this.windowMethods = {};
   ['alert', 'confirm', 'prompt', 'open'].forEach(function(method) {
           this.windowMethods[method] = window[method];
       }, this);
   var self = this;
   window.alert = function(alert) {
       self.windowMethods['alert'].call(self.window, alert);
       self.record('assertAlert', alert);
   }
}

这是因为函数调用实际上在运行时被 Selenium 自己的 JavaScript 覆盖了。添加下面Javascript代码到selenium core user extension，重启后可以解决这个问题。

//http://docs.seleniumhq.org/docs/08_user_extensions.jsp
Selenium.prototype.doExecute = function(script) {
    this.browserbot.getCurrentWindow().eval(script);
};
Selenium.prototype.getExecute = function(script) {
    return this.browserbot.getCurrentWindow().eval(script);
};
Selenium.prototype.getJqMethod = function(selector, method) {
    return this.getExecute('$("' + selector + '").' + method + '();');
};
Selenium.prototype.getJqText = function(selector) {
    return this.getJqMethod(selector, "text");
};
Selenium.prototype.getJqHtml = function(selector) {
    return this.getJqMethod(selector, "html");
};
Selenium.prototype.getJqVal = function(selector) {
    return this.getJqMethod(selector, "val");
};
PageBot.prototype.locateElementByJq = function(selector, inDocument) {
    // FF/Chrome/IE9+: defaultView, OldIE: parentWindow
    return (inDocument.defaultView || inDocument.parentWindow)
            .eval("jQuery('" + selector.replace(/'/g, "\'") + "')[0];");
};
