除了输入数据之外，测试人员需要校验显示的数据或应用程序的输出是否是正确的。

In addition to entering data, testers need to verify that the data displayed, or output by the application, is correct.

例如，考虑校验和，如果文件格式包含一个校验和，在将文件传至应用程序前仅仅修改此校验和就可以使其同随机数据相匹配。

For example, consider checksums. If a file format contains a checksum, then you simply modify the checksum so it matches your random data before passing the file to the application.

我们使用了一个校验和报表统计应用程序的例子向您介绍了使用Groovy编写ant脚本和一个数据库报表统计来展示使用GroovySql进行JDBC编程。

I used a checksum reporting application example to show you the basics of Ant scripting with Groovy and a database statistics report to demonstrate the benefits of JDBC programming with GroovySql.
