今天继续完成测试用例的相关功能，因为我们这个平台内容比较多，一个测试用例可能关联的属性也比较多，具不完全统计大概有：环境、项目、服务、模块、接口、用例级别、创建人和编辑人等。所以这块功能在写的时候都需要关联很多表去查询或者写入数据。不做不知道，原来自己之前掌握的MySQL语句的知识，太浅薄了。
今天主要用到了MySQL语法case when then else end、FIND_IN_SET函数和多种非必选条件和判断语句的练习（这个其实就是复杂一些）。中间还发现了mybatis其实替用户做了一些兼容性的处理，比如我在拼WHERE条件语句的时候，每个都是and condition，本来还担心要不要去掉第一个and，经过咨询前辈才知道，这块不要直接拼WHERE语句，可以用<where></where>这个mybatis语法即可完成，非常友好。今天学到的第二个就是异步查询转同步，在之前的文章已经讲过了，今天算是又实践了一下，写实际的业务跟练习区别还是挺大。
MySQL语法case when then else end实践
需求大概就是从很多非必传参数里面搜索库里面的用例，这些条件包括：环境、项目、服务、模块、接口等等，如下图：
然后接口传参都是int和string类型，0表示全部，各个选项状态不一。在处理搜索框的搜索类型时候，我提前做了判断，如果内容是个数字，那么我就认为是搜索ID，否则我认为是搜索用例名（模糊匹配），因此我引入了另外一个type作为记录。接收参数的类代码如下：
class CaseSearchBean extends AbstractBean {
private static final long serialVersionUID = -869483426556;
int id
@Min(value = 1L)
int uid
int envId
int apiId
@Range(min = 0L, max = 2L, message = "是否本人参数错误")
int isMyself
@Range(min = 0L, max = 2L, message = "是否可用参数错误")
int isUsed
int serviceId
int moduleId
@Min(value = 1L)
int pageNum
@Range(min = 5L, max = 10L)
int pageSize
int projectId
String testQuery
/**
* 处理搜索类型,1:用例名模糊搜索,2:用例id精确搜索
*/
int type
def init() {
if (StringUtils.isEmpty(testQuery)) return
if (SourceCode.isNumber(testQuery)) type = 2
else type = 1
}
}
由于业务不多，中间的service和mapper接口就不放了。

异步查询转同步
相关文章和测试方案请参考:
这个地方主要是因为用例关联的项目和版本比较多，返回格式要求是array<object>格式的id+name形式对象，所以单独拿出来查了。业务实现类的相关代码如下：
@Override
public TestCaseAttributeBean getAttributeById(int id) {
TestCaseAttributeBean bean = new TestCaseAttributeBean();
bean.setId(id);
CountDownLatch countDownLatch = new CountDownLatch(2);
getAttributeById(bean, countDownLatch);
getCaseProjectRelation(bean, countDownLatch);
try {
countDownLatch.await(10, TimeUnit.SECONDS);
} catch (InterruptedException e) {
CaseException.fail("查询用例信息发生错误:" + e.getMessage());
}
return bean;
}
@Async
@Override
public void getAttributeById(TestCaseAttributeBean bean, CountDownLatch countDownLatch) {
try {
TestCaseAttributeBean attributeById = testCaseMapper.getAttributeById(bean.getId());
bean.copyFrom(attributeById);
} finally {
countDownLatch.countDown();
}
}
@Async
@Override
public void getCaseProjectRelation(TestCaseAttributeBean bean, CountDownLatch countDownLatch) {
try {
bean.setVersionList(testCaseMapper.getCaseProjectRelation(bean.getId()));
} finally {
countDownLatch.countDown();
}
}
bean代码
本来打算用AbstractBean类的copyFrom()方法的，发现不太好，只能重写了一个。
class TestCaseAttributeBean extends AbstractBean {
private static final long serialVersionUID = -1595563071153477L;
int id
int apiId
String apiName
int envId
String envName
int moduleId
String moduleName
String name
int serviceId
String serviceName
List<ProjectBean> versionList
/**
* 用于异常查询结果赋值
* @param bean
*/
@Override
def copyFrom(TestCaseAttributeBean bean) {
this.id = bean.getId()
this.apiName = bean.getApiName()
this.envId = bean.getEnvId()
this.envName = bean.getEnvName()
this.moduleId = bean.getModuleId()
this.moduleName = bean.getModuleName()
this.name = bean.getName()
this.serviceId = bean.getServiceId()
this.serviceName = bean.getServiceName()
}
}
当然还需要在启动类的增加注解，开启异步任务功能。
@EnableScheduling
@MapperScan(value = "com.okay.family.mapper")
@ServletComponentScan
@EnableAsync
@EnableTransactionManagement
@SpringBootApplication(exclude = {MongoAutoConfiguration.class, MongoDataAutoConfiguration.class})
public class FamilyApplication {
public static void main(String[] args) {
SpringApplication.run(FamilyApplication.class, args);
}
}
