Inspired by the recently added support for resource patterns in
@PropertySource locations, this commit adds the same support for
resource locations in @TestPropertySource.
For example, assuming the `config` folder in the classpath contains
only 3 files matching the pattern `file?.properties`,
... the following:
@TestPropertySource("classpath:/config/file1.properties")
@TestPropertySource("classpath:/config/file2.properties")
@TestPropertySource("classpath:/config/file3.properties")
... or:
@TestPropertySource({
"classpath:/config/file1.properties",
"classpath:/config/file2.properties",
"classpath:/config/file3.properties"
})
... can now be replaced by:
@TestPropertySource("classpath*:/config/file?.properties")

Spring Framework 4.3 introduced the `PropertySourceFactory` SPI for use
with `@PropertySource` on `@Configuration` classes; however, prior to
this commit there was no mechanism to support custom properties file
formats in `@TestPropertySource` for integration tests.
This commit introduces support for configuring a custom
`PropertySourceFactory` via a new `factory` attribute in
`@TestPropertySource` in order to support custom file formats such as
JSON, YAML, etc.
For example, if you create a YamlPropertySourceFactory, you can use it
in integration tests as follows.
@SpringJUnitConfig
@TestPropertySource(locations = "/test.yaml", factory = YamlPropertySourceFactory.class)
class MyTestClass { /* ... /* }
If a custom factory is not specified, traditional `*.properties` and
`*.xml` based `java.util.Properties` file formats are supported, which
was the existing behavior.

Prior to this commit, if an error was encountered during build-time AOT
processing, the error was logged at WARN/DEBUG level, and processing
continued.
With this commit, test AOT processing now fails on error by default. In
addition, the `failOnError` mode can be disabled by setting the
`spring.test.aot.processing.failOnError` Spring/System property to
`false`.
Closes gh-30977
This commit overhauls the TestExecutionListener for Micrometer's
ObservationRegistry that was introduced in the previous commit.
Specifically, this commit:
- Renames the listener to MicrometerObservationRegistryTestExecutionListener
since the use of a ThreadLocal is an implementation detail that may
change over time.
- Makes the listener package-private instead of public in order to
allow the team greater flexibility in evolving this feature.
- Eagerly loads the ObservationThreadLocalAccessor class and verifies
that it has a getObservationRegistry() method to ensure that the
listener is properly skipped when SpringFactoriesLoader attempts to
load it, if Micrometer 1.10.8+ is not on the classpath.
- Switches the listener's automatic registration order to 2500 in order
to register it after the DependencyInjectionTestExecutionListener.
- Only tracks the previous ObservationRegistry in beforeTestMethod() if
the test's ApplicationContext contains an ObservationRegistry bean.
- Properly removes the TestContext attribute for the previous
ObservationRegistry in afterTestMethod().
- Introduces DEBUG logging for diagnostics.
- Adds an entry in the Javadoc for TestExecutionListener as well as in
the Testing chapter in the reference manual.
Closes gh-30658
