Question

我正在使用testNG运行2个类。第一个类成功运行但第二个类失败并出现错误：

“org.testng.TestNGException：无法调用public void TestScripts.NewAccountCreation.AccountCreation1（）：要么将它设为静态，要么在你的类中添加一个no-args构造函数”

如果我添加非参数构造函数，我将获得空指针异常。

我正在使用Pagefactory设计我的测试用例。

Eclipse版本：kepler

TestNG的：6.9.9

Chrome版本：57.0.2987.133

Chrome驱动程序：2.27

任何建议都将不胜感激。

请找到以下代码：

Answer 1

NewAccountCreation是一个测试类，因为它包含测试方法，因为您在testng.xml中将其声明为类测试。

所以，这意味着TestNG必须能够创建一个类的实例，这就是TestNG抱怨的原因。

您有两个选择：

使用a factory向TestNG解释如何创建测试类（最佳选择IMO）
使用静态共享驱动程序实例（Login#driver不是但是静态的）

使用pagefactory
