Question

当我从selenium web驱动程序运行此测试用例时，我收到以下错误：

您正在使用带有Oracle URL的Microsoft SQL Server JDBC驱动程序类。

// Load Microsoft SQL Server JDBC driver.
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");

这是完全错误的。获取Oracle JDBC驱动程序JAR。您必须将驱动程序与要连接的数据库进行匹配。

您迫切需要JDBC tutorial。

您也可以使用如何正确编写JUnit测试的课程。我建议您将这些连接外部化并加强这些测试。

没有为jdbc找到合适的驱动程序：oracle：thin：
