Junit本是不支持多线程的,一个单元测试case主进程跑完,其他new出来的线程都会GG思密达。此篇mark一份在Junit中执行多线程的方法。

方案一

  • 添加依赖 pom.xml
<!-- https://mvnrepository.com/artifact/net.sourceforge.groboutils/groboutils-core -->
        <dependency>
            <groupId>net.sourceforge.groboutils</groupId>
            <artifactId>groboutils-core</artifactId>
            <version>5</version>
            <scope>test</scope>
        </dependency>

测试case

            for (int i = 0; i < n; i++) {
                trs[i] = new DeviceMsgTaskRunnable();
            }

                    DeviceInfoBO db = list.get((int) (Math.random() * list.size()));
                    DeviceStatusDTO deviceStatusDTO = new DeviceStatusDTO();
                    deviceStatusDTO.setAppKey(db.getAppKey());
                    deviceStatusDTO.setTimeFlag(new Date().getTime());
                    deviceStatusDTO.setDeviceCode(db.getDeviceCode());
                    if (db.getIsOnline() == MainConstant.DEVICE_CURRENT_OFFLINE) {
                        deviceStatusDTO.setStatus(true);
                    } else {
                        deviceStatusDTO.setStatus(false);
                    }
                    log.info(JSONObject.toJSONString(deviceStatusDTO));
                    deviceMessageSolver.doStatus(deviceStatusDTO);
                } catch (Exception e) {
                    log.error("线程执行异常", e.getMessage());
                }
            }
        }
    }
}

关键代码:

1.class DeviceMsgTaskRunnable extends TestRunnable
2.TestRunnable[] trs = new TestRunnable[n];
3.for (int i = 0; i < n; i++) {
	  trs[i] = new DeviceMsgTaskRunnable();
   }
4.MultiThreadedTestRunner mttr = new MultiThreadedTestRunner(trs);
5.mttr.runTestRunnables();
