How to test a maven service which needs another service in java?

问题

我已经搜索了两天以寻找答案。我尝试了@Mock、@InjectMock和@Spy，并尝试了不同的附加操作，但是没有任何一个按照教程中描述的那样工作。我找到的许多问题都涉及Angular中的问题，这是我第一个spring-boot/maven项目，以前从未使用过Angular。

我有一个基本的服务用于一些我希望只能在那里更改的值，但是需要在多个其他服务中使用它们。我已经编写了一个缩短版的示例，展示了我想要测试的基本结构，并且我包含了我目前找到的解决方法，但我很想知道有经验的程序员会如何处理这个问题。

我有一个配置服务：

  1. @Service
  2. public class ConfigService {
  3.     private final int initialLength = 4;
  5.     public int getInitialLength() {
  6.         return initialLength;
  7.     }
  9.     public double getInitialSquared() {
  10.         return Math.pow(4, 2);
  11.     }    
  12. }

还有另一个使用它的服务：

  1. @Service
  2. public class OtherService {
  4.     @Autowired
  5.     ConfigService configService;
  7.     // 目前我如何绕过它是通过重载，只测试第二个函数
  8.     String printLine() {
  9.         return printLine(configService.getInitialLength());
  10.     }
  12.     String printLine(int length) {
  13.         StringBuilder output = new StringBuilder();
  14.         for (int i = 0; i < configService.getInitialLength(); i++) {
  15.             output.append("-");
  16.         }
  17.         return output.toString();
  18.     }
  20. }

以及我的目前的测试：

  1. class OtherServiceTest {
  3.     @InjectMocks
  4.     OtherService otherService = new OtherService();
  6.     @Test
  7.     void printLine() {
  8.         AssertEquals("----", OtherService.printLine(4));
  9.     }
  10. }

I have searched two days for an answer. I tried @Mock, @InjectMock and @Spy with different additional things, but nothing worked how it was described in tutorials. Many Questions I found dealt with a Problem in Angular, this is my first spring-boot/maven project and have never worked with Angular.

I have a Basic Service for some values I want to be able to change only there but need them in multiple other services. I have written a shortened example of the base structure I want to test and I included the workaround I found for the moment, but would love to know how experienced programmers would go about this.

I have my configuration Service:

  1. @Service
  2. public class ConfigService {
  3. 	private final int initialLength = 4;
  5. 	public int getInitialLength() {
  6. 		return initialLength;
  7. 	}
  9. 	public double getInitialSquared() {
  10. 		return Math.pow(4,2);
  11. 	}    
  12. }

And another Service using it:

  1. @Service
  2. public class OtherService {
  4. 	@Autowired
  5. 	ConfigService configService;
  7. 	// How I surpassed it for now is overloading and only testing the second function
  8. 	String printLine() {
  9. 		return printLine(configService.getInitialLength());
  10. 	}
  12. 	String printLine(int length) {
  13. 		StringBuilder output = new StringBuilder();
  14. 		for (int i = 0; i &lt; configService.getInitialLength(); i++) {
  15. 			output.append(&quot;-&quot;);
  16. 		}
  17. 		return output.toString();
  18. 	}
  20. }

And my Test for now:

  1. class OtherServiceTest {
  3. 	@InjectMocks
  4. 	OtherService otherService = new OtherService();
  6. 	@Test
  7. 	void printLine() {
  8. 		AssertEquals(&quot;----&quot;, OtherService.printLine(4));
  9. 	}
  10. }
