This commit add mock support for WebFlux with an infrastructure similar
to what `WebMvcTest` provides. `@WebFluxTest` can be used to test
controllers with a narrowed classpath that is relevant to WebFlux. Also,
`@SpringBootTest` now starts WebFlux in "mock" mode by default and
`@AutoConfigureWebTestClient` can be used to inject a `WebTestClient`
connected to the `ApplicationContext`.
To make that happen, a `ReactiveWebApplicationContext` interface has been
introduced to mirror what `WebApplicationContext` currently does. Things
are still a bit volatile at this point and that infra may move to Spring
Framework at some point.
Closes gh-8401
This commit exposes a `WebTestClient` automatically in a reactive
integration test that uses an embedded web server. This is similar to
what we do with `TestRestTemplate` for servlet based integration tests.
Closes gh-8399
This commit makes sure that `@SpringBootTest` with a reactive setup
starts a web application if necessary.
If both a servlet and a reactive environment are available, a servlet
environment is bootstraped. This commit also adds a way to force a
reactive environment by specifying the `spring.main.web-application-type`
property of the test (e.g. `@TestPropertySource`).
Closes gh-8383
Previously, @SpyBean's name attribute was not used when determining
the name of the bean to spy upon. When there were multiple candidates,
none of which were primary, this would lead to a failure to find the
bean to spy upon. This behaviour is also inconsistent with @MockBean
which does use the name attribute to identify the bean to mock.
This commit updates MockitoPostProcessor to use the name attribute,
when set, to identify the bean that should be spied upon. For
consistency with @MockBean it is always used when set. When not set
the previous logic will continue to be used.
Closes gh-8315
This commit refactors the `ServerProperties` property keys and
introduces a separate "server.servlet" namespace to isolate
servlet-specific properties from the rest.
Closes gh-8066
This commit introduces a new variant of web applications: there are now
Servlet based and Reactive web applications.
The mere presence of `Servlet` and `ConfigurableWebApplicationContext`
classes is not enough to make a difference between those variants.
This is why the decision process is now the following:
* if `DispatcherHandler` is present but not `DispatcherServlet`, the
WebApplicationType is detected as REACTIVE
* if `DispatcherHandler` is present and `DispatcherServlet`, this is a
case where we consider that developers are using Spring MVC in
combination with the reactive web client. So WebApplicationType is
detected as SERVLET
* if `Servlet` and `ConfigurableWebApplicationContext` are present,
WebApplicationType is detected as SERVLET
* if none of the above match, WebApplicationType is NONE

Previously, TestRestTemplate applied the root URI to URIs by
converting them to a String and then passing the String to the
RestTemplate delegate. Being a String, meant that the URI passed
through RestTemplate's standard URI template expansion processing
using the configured UriTemplateHandler. While this caused the root
URI to be applied, it also had the unwanted side-effect of
encoding the URI for a second time.
This commit updates TestRestTemplate so that, when configured with a
RootUriTemplateHandler, it applies the root URI directly and then
passes a modified URI to the RestTemplate delegate. Being a URI means
that no template expansion is performed and the possible double
encoding is avoided.

The caching behaviour when using ImportAutoConfiguration is covered
by tests in spring-boot-test-auto-configuration, specifically by
ImportsContextCustomizerFactoryWithAutoConfigurationTests.
See gh-7953
Update `ImportsContextCustomizer` so that whenever possible a more
specific cache key is used.
Prior to this commit the customizer would generate a key based on *all*
annotations on the test class. This has repeatedly caused issues where
test classes that should have the same cache key did not due to
unrelated annotations.
A new `DeterminableImports` interface has been added that can be
implemented by `ImportSelector` and `ImportBeanDefinitionRegistrar`
implementations that are able to determine their imports early. The
existing `ImportAutoConfigurationImportSelector` and
`AutoConfigurationPackages` classes have been retrofitted with
this interface.
Fixes gh-7953
Previously, TestRestTemplate would only apply the UriTemplateHandler
to Strings and not to URIs. When using the auto-configured
TestRestTemplate, this prevented relative URIs from being
made absolute using LocalHostUriTemplateHandler.
The commit updates TestRestTemplate to turn URIs into Strings before
passing them to the delegate RestTemplate. Turning them into Strings
ensures that the delegate calls the UriTemplateHandler.
Closes gh-7891
