This commits adds a slice test infrastructure for MongoDB, similar to
what `@DataJpaTest` does with JPA.
By default, an embedded Mongod process is used if available.
See gh-7600
By default, `@DataJpaTest` (and `@AutoConfigureTestDatabase`) attempt to
replace any existing `DataSource` by an embedded one. Previously, if
there is was no embedded database on the classpath, the exception message
did not provide that context in the error message.
This commit clarifies the error message to conduct
`TestDatabaseAutoConfiguration` (that is replacing the existing
`DataSource`).
Closes gh-7797
Most of the config keys defined by the `spring-boot-test-autoconfigure`
module can't be overridden because they are mapped with `@PropertyMapping`
on an annotation. It is confusing that such keys are exposed in content
assistance as using them will have no effect.
This commit removes the annotation processor from the build so that the
`@ConfigurationProperties` beans aren't processed anymore. Instead, manual
metadata is written for the two only keys that are effectively used in
regular configuration.
As a result, the `additional-spring-configuration-metadata` file has been
renamed to `spring-configuration-metadata` since nothing is processing it
anymore.
Closes gh-7887
Update `@ImportAutoConfiguration` with support for an exclude attribute
that works in a similar way to `@EnableAutoConfiguration`.
Also update existing `@Test...` annotation with exclude attribute
aliases.
Fixes gh-6809
