Assuming that the `username` property has not be set elsewhere, `app.description` will have the value `MyApp is a Spring Boot application written by Unknown`.
Assuming that the `username` property has not been set elsewhere, `app.description` will have the value `MyApp is a Spring Boot application written by Unknown`.

TIP: You can also use this technique to create "`short`" variants of existing Spring Boot properties.
See the _<<howto#howto.properties-and-configuration.short-command-line-arguments>>_ how-to for details.

For a `@WebMvcTest` for an application with the above `@Configuration` class, you might expect to have the `SecurityFilterChain` bean in the application context so that you can test if your controller endpoints are secured properly.
However, `MyConfiguration` is not picked up by @WebMvcTest's component scanning filter because it doesn't match any of the types specified by the filter.
You can include the configuration explicitly by annotating the test class with `@Import(MySecurityConfiguration.class)`.
You can include the configuration explicitly by annotating the test class with `@Import(MyConfiguration.class)`.
This will load all the beans in `MyConfiguration` including the `BasicDataSource` bean which isn't required when testing the web tier.
Splitting the configuration class into two will enable importing just the security configuration.

Having a single configuration class can be inefficient when beans of a certain domain needed to be included in slice tests.
Having a single configuration class can be inefficient when beans of a certain domain need to be included in slice tests.
Instead, structuring the application's configuration as multiple granular classes with beans for a specific domain can enable importing them only for specific slice tests.

For that, you can add a bean of type `ErrorAttributes`.

To change the error handling behavior, you can implement `ErrorWebExceptionHandler` and register a bean definition of that type.
Because a `ErrorWebExceptionHandler` is quite low-level, Spring Boot also provides a convenient `AbstractErrorWebExceptionHandler` to let you handle errors in a WebFlux functional way, as shown in the following example:
