Unable to find a @SpringBootConfiguration, you need to use @ContextConfiguration or @SpringBootTest(classes=...) with your test

If you are encountering the error message "Unable to find a @SpringBootConfiguration, you need to use @ContextConfiguration or @SpringBootTest(classes=...) with your test," it means that Spring Boot is unable to detect the configuration class for your test.

To resolve this issue, you have a few options:

1. Use @ContextConfiguration: Annotate your test class with @ContextConfiguration and specify the location of your configuration file(s). For example:

public class MyTest {
 // ...
}

2. Use @SpringBootTest(classes=...): Annotate your test class with @SpringBootTest and specify the configuration class(es) using the "classes" attribute. For example:

public class MyTest {
 // ...
}

Make sure to replace `MyConfiguration` with the actual class that contains your Spring Boot configuration.

3. Check your test package structure: Ensure that your test class is located in the same or a sub-package of your main application class. By default, Spring Boot will automatically scan for configuration classes within its package and sub-packages.

By applying one of these solutions, you should be able to resolve the error and properly configure Spring Boot for your tests.
