ObjectMapper mapper = new ObjectMapper(new YAMLFactory());
List<TestData> data = mapper.readValue(
new File(AssertionTestData.class.getResource("/data/testdata.yaml").getFile()),

读取配置文件

ObjectMapper mapper = new ObjectMapper(new YAMLFactory());
try {
mapper.writeValue(new File(filePath), new MeiTuanConfig());
} catch (IOException e) {
e.printStackTrace();
}
}
public static MeiTuanConfig load(String filePath){
ObjectMapper mapper = new ObjectMapper(new YAMLFactory());
MeiTuanConfig conf=new MeiTuanConfig();
try {
conf=mapper.readValue(new File(filePath), MeiTuanConfig.class);
} catch (IOException e) {
e.printStackTrace();
}
return conf;
}
测试用例管理
三种至关重要的顺序控制
- 套件级别的顺序控制
- 继承关系里的初始化顺序
- 单个类里的执行顺序
企业微信演练
Swagger
Dubbo
小作业1
创建一个三层的继承关系，所有的Class里都添加上类级别的初始化BeforeClass和方法级别的初始化Before，打印下所有方法的执行流程。
A->B->C->3个用例
作业2
读取一个三行两列的csv数据，这个数据里是字符串，断言两个字符串是否相等
作业3
从YAML文件里读取3个数据，两个数字，一个字符串。构建一个数据驱动的测试用例，根据两个数字的相加，判断是否等于字符串。
作业4
完成企业微信的接口测试用例体系。提前演练，下节课重点实训。把完整的项目代码上传到github并把仓库地址贴到回复里。
拔高题
做一个小的基于yaml的接口测试工具，支持发送请求和断言。
