我一直在尝试为 100% 的覆盖率编写测试类。我很难理解如何调用标准控制器并调用参数化构造函数还将页面设置为当前页面作为当前页面。在帐户视图页面上，我已经覆盖了自定义对象相关列表上的新按钮。当我编辑记录时，我可以使用相同的类。在编辑记录视图页面和新记录视图页面上，我都可以检索帐户 ID。目前我能够达到 65% 的覆盖率。我不确定我做错了什么。如果可能，请提供帮助。我附上了下面的代码。

谢谢加亚特里

//my Class

            for (State__c iso : State__c.getAll().values())
            options.add(new SelectOption(iso.State_ISO__c,iso.State_Name__c+' - '+iso.State_ISO__c));

            return options;

如果您知道测试覆盖率中缺少代码的哪一部分，那将会容易得多。

  1. 转到开发人员控制台并运行您的测试
  2. 在页面底部选择测试选项卡
  3. 从右侧找到您的测试（标题：总体代码覆盖率）
  4. 双击你的测试

未覆盖的部分将显示为红色。现在尝试为他们编写测试。

如果你想覆盖你的类属性，你所要做的就是：

@isTest static void myPropertiesTest(){

    MyClass obj = new MyClass();
    obj.myProperty = SomeValue;
    // now assert a function in you class that uses this property. 

    // an easy and dumb way is to just assert the property. 
    System.assertEquals(SomeValue, obj.myProperty);
}
