ABAP

在ABAP类里，的单元本地类(Local Class)里用关键字FOR TESTING声明过的测试方法，

在单元测试启动后会自动被调用到。

Spring Boot

在Spring及Spring Boot “Convention over configuration”的测试设定思路里，放在路径src/test/java下面以Tests.java结尾的的高防服务器单元Java类会被当成单元测试类处理。

对上述项目执行命令行mvn clean install后，报错误消息：

java.lang.IllegalStateException: Unable to find a @SpringBootConfiguration,的单元 you need to use @ContextConfiguration or @SpringBootTest(classes=...) with your test at org.springframework.util.Assert.state(Assert.java:70) at org.springframework.boot.test.context.SpringBootTestContextBootstrapper.getOrFindConfigurationClasses(SpringBootTestContextBootstrapper.java:202) at org.springframework.boot.test.context.SpringBootTestContextBootstrapper.processMergedContextConfiguration(SpringBootTestContextBootstrapper.java:137) at org.springframework.test.context.support.AbstractTestContextBootstrapper.buildMergedContextConfiguration(AbstractTestContextBootstrapper.java:409) at org.springframework.test.context.support.AbstractTestContextBootstrapper.buildDefaultMergedContextConfiguration(AbstractTestContextBootstrapper.java:323) at org.springframework.test.context.support.AbstractTestContextBootstrapper.buildMergedContextConfiguration(AbstractTestContextBootstrapper.java:277) at org.springframework.test.context.support.AbstractTestContextBootstrapper.buildTestContext(AbstractTestContextBootstrapper.java:112) at org.springframework.boot.test.context.SpringBootTestContextBootstrapper.buildTestContext(SpringBootTestContextBootstrapper.java:82) at org.springframework.test.context.TestContextManager.<init>(TestContextManager.java:120) at org.springframework.test.context.TestContextManager.<init>(TestContextManager.java:105) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.createTestContextManager(SpringJUnit4ClassRunner.java:152) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.<init>(SpringJUnit4ClassRunner.java:143) at org.springframework.test.context.junit4.SpringRunner.<init>(SpringRunner.java:49) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:422) at org.junit.internal.builders.AnnotatedBuilder.buildRunner(AnnotatedBuilder.java:104) at org.junit.internal.builders.AnnotatedBuilder.runnerForClass(AnnotatedBuilder.java:86) at org.junit.runners.model.RunnerBuilder.safeRunnerForClass(RunnerBuilder.java:59) at org.junit.internal.builders.AllDefaultPossibilitiesBuilder.runnerForClass(AllDefaultPossibilitiesBuilder.java:26) at org.junit.runners.model.RunnerBuilder.safeRunnerForClass(RunnerBuilder.java:59) at org.junit.internal.requests.ClassRequest.getRunner(ClassRequest.java:33) at org.apache.maven.surefire.junit4.JUnit4Provider.execute(JUnit4Provider.java:283) at org.apache.maven.surefire.junit4.JUnit4Provider.executeWithRerun(JUnit4Provider.java:173) at org.apache.maven.surefire.junit4.JUnit4Provider.executeTestSet(JUnit4Provider.java:153) at org.apache.maven.surefire.junit4.JUnit4Provider.invoke(JUnit4Provider.java:128) at org.apache.maven.surefire.booter.ForkedBooter.invokeProviderInSameClassLoader(ForkedBooter.java:203) at org.apache.maven.surefire.booter.ForkedBooter.runSuitesInProcess(ForkedBooter.java:155) at org.apache.maven.surefire.booter.ForkedBooter.main(ForkedBooter.java:103)

从调用栈能看出，Spring Boot单元测试框架试图自动找到一个被施加单元测试的测试Java类，但是的网站模板单元失败了，所以报了异常。测试

由于我这个SpringBoot项目的入口是com.sap.smartService.SmartServiceApplication, 因此我需要在单元测试启动类里指定这个入口类：

@SpringBootTest(classes = com.sap.smartService.SmartServiceApplication.class)

加上之后maven build成功：
