Rename `ApplicationContextTester` and related classes to
`ApplicationContextRunner` and refactor existing tests to use correctly
named variables.
See gh-9875
Rename `ContextLoader` to `ApplicationContextTester` and provide
distinct subclasses for standard, web and reactive application contexts.
Context callbacks now return AssertJ compatible contexts, allowing
tests to run directly on context. For example:
context.run((loaded) -> assertThat(loaded).hasBean("foo"));
The returned context can now also represent a context that has failed
to start (meaning that the `loadAndFail` methods are no longer needed):
context.run((loaded) -> assertThat(loaded).hasFailed());
Configuration classes are loaded via the recently introduced
`Configurations` class. This means that the tester no longer needs to
be directly aware of auto-configuration concepts.
See gh-9634
Update `TestPropertyValues` so that it can also be used to update
system properties. Properties are set before the call is made and
restored to their previous value afterwards.
Fixes gh-9792
This commit adds ContextLoader, a test helper that configures an
ApplicationContext that is meant to simulate a particular
auto-configuration scenario.
The auto-configuration, user configuration and environment can be
customized. The loader invokes a ContextConsumer to assert the context
and automatically close the context once it is done.
Concretely, tests can create a shared field instance of that helper with
the shared configuration to increase its visibility and tune the context
further in each test.
If the context is expected to fail, `loadAndFail` allows to optionally
assert the root exception and consume it for further assertions.
This commit also migrates some tests to illustrate the practical use of
the helper

Remove test-jar artifacts from Maven projects and relocate classes. The
majority of utilities now live in the `spring-boot-testsupport` module.
This update will help us to deploy artifacts using the standard Maven
deploy plugin in the future (which doesn't support the filtering of
individual artifacts).
Fixes gh-9493
Relax `SpringBootTestContextBootstrapper` rules so that a test can
specify an `ApplicationContextInitializer` and still have
`@SpringBootConfiguration` detected.
Prior to this commit detection would not occur because it's possible
that an initializer _could_ register configuration. This scenario is
actually quite unlikely to occur, certainly less likely than wanting to
use an initializer in combination with auto-detection.
Fixes gh-8483
Update SpringBootTestContextBootstrapper to detect `@ContextHierarchy`
annotations so that only the last child creates a
`WebApplicationContext`.
Prior to this commit a context hierarchy would start two embedded web
servers which is inconsistent with the `SpringApplicationBuilder`
behavior.
Fixes gh-8311
Restructure `org.springframework.boot.autoconfigure.web` to better align
with the new package structure in `spring-boot`.
Auto-configuration is now split into client, servlet and reactive
sub-packages. In addition a new `http` package now handles common
HTTP concerns.
Fixes gh-8616
Rework `org.springframework.boot.context.embedded` to relocate classes
to `org.springframework.boot.web`. Packages are now organized around
the following areas:
Packages for shared concerns, for example the `WebServer` interface
to start/stop a server and the common configuration elements:
- org.springframework.boot.web.context
- org.springframework.boot.web.server
Servlet specific packages:
- org.springframework.boot.web.servlet.server
- org.springframework.boot.web.servlet.context
- org.springframework.boot.web.servlet.filter
Reactive specific packages:
- org.springframework.boot.web.reactive.context
- org.springframework.boot.web.reactive.server
Embedded server implementations (both reactive and servlet):
- org.springframework.boot.web.embedded
In addition:
- Rename `EmbeddedServletContainerFactory` to `ServletWebServerFactory`
to align with the `ReactiveWebServerFactory`.
- Rename `EmbeddedWebApplicationContext` to
`ServletWebServerApplicationContext` and
- Rename `EmbeddedReactiveWebApplicationContext` to
`ReactiveWebServerApplicationContext`.
- Add checkstyle rules to restrict imports.
- Fixup all affected code to use the correct imports and local names.
Fixes gh-8532
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
