API 测试（16）

来源：互联网发布：淘宝订单号查询系统编辑：程序博客网时间：2024/04/29 02:08

示例程序：ApiTest

此程序综合了前15篇的多种技术，编写了一个完整的轻量级的API测试套件。待测方法包括：ArithmeticMean(),GeometricMean()和HarmonicMean()，它们在API开始时候描述过。轻量级测试套件完整代码如下，这个程序从TestCases.txt文件每次读入一行测试用例数据。然后测试套件会解析出测试用例ID，并且一并得到待测方法的名称、输入值和期望值。输入值为传给待测方法，接下来程序把得到的实际结果和测试用例的期望结果进行比较。测试通过与否，最终的结果会发送到命令行程序并且记录到TestResults.txt文件
