junit是无法进行并发测试,但是又有需要并发测试的场景怎么办呢?此时可以借助一个插件(Groboutils Core)来完成这种功能。
maven仓库地址:https://mvnrepository.com/artifact/net.sourceforge.groboutils/groboutils-core
第一步:在项目的pom.xml中加入依赖:
<!-- 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>
第二步:在单测中进行代码编写
@Test public void testConcurrentInitOrBind() { // mock一个返回 doReturn(Lists.newArrayList(userMemberCard)).when(operateCardDao) .queryCardByRegisterMobileAndTenantId(anyString(), anyLong()); TestRunnable runner = new TestRunnable() { // 在runTest方法中填写自己的测试方法 @Override public void runTest() throws Throwable { InitCardResVo resVoFirst = operateCardService.initOrBindCard(requestVo); System.out.println("result resVoFirst is:" + resVoFirst.toString()); } }; // 一个数组,代表并发个数。此处并发5个 TestRunnable[] trs = new TestRunnable[5]; for (int i = 0; i < 5; i++) { trs[i] = runner; } MultiThreadedTestRunner mttr = new MultiThreadedTestRunner(trs); try { mttr.runTestRunnables(); } catch (Throwable ex) { ex.printStackTrace(); } }
