Fixes https://github.com/spring-projects/spring-integration/issues/3686
* Add `src/idea` with respective editor config for IntelliJ IDEA.
Must be imported into an IDE
* Add `src/eclipse` with respective editor config for Eclipse/STS
* Reformat imports in source code according a new editor config
* Add `org.gradle.caching=true` and `org.gradle.parallel=true` into a `gradle.properties`
* Fix `Matcher` tests in the `spring-integration-test-support` for the latest JUnit 4
Mostly thanks to IDEA's plugin: https://plugins.jetbrains.com/plugin/10345-assertions2assertj
There is still a lot of work to do when complex and composite matchers are used.
* Add `awaitility` dependency and deprecate `EventuallyMatcher` in favor
of `awaitility`
* Remove Hamcrest from dependencies and disable JUnit & Hamcrest
static imports to encourage to use only AssertJ
* Migrate JUnit assumptions in rules to AssertJ's assumptions
* Deprecate some custom matchers in favor of existing in Hamcrest
after upgrading the last to version `2.1`
* Replace `ExpectedException` rules with `assertThatThrownBy()`
* Mention `MessagePredicate` in the `testing.adoc`
* INT-4376: Upgage to Log4J 2
JIRA: https://jira.spring.io/browse/INT-4376
* Deprecate Log4J 1.x components in favor of newly added
a `Log4j2LevelAdjuster` JUnit `@Rule`
* Update all the logging configuration to Log4J 2
* Polishing after testing
JIRA: https://jira.spring.io/browse/INT-4364
Always let the OS choose the ports for tests.
Just one test remains (RMI) because there appears to be no way to obtain
the port after creating a registry with a 0 port.
This test has been switched to use the Spring utility.
Polishing - PR Comments
Fix PayloadMatcherTests for generics
Address PR comments and other improvements
* Revert `rawtypes` mode for the `PayloadMatcher`
* Make `HeaderMatcher` as `rawtypes` as well
* Make `MockMessageHandler` expect `rawtypes` for `Matcher`s.
This way we can just support `Matcher`s like `notNullValue(Message.class)`
* Rename `expect()` to `assertNext()`
* Rename `andReply()` to `thenReply()`
* Track replies are supplied in the `MockMessageHandler`
* Distinguish simple `MH` from the `MP` types in the
`MockIntegrationContext#instead()` do not let to replace simple `MH`
with fully configured `MockMessageHandler` or any other `MP` implementation.
Fail replace if types mismatch; wrap `MockMessageHandler` to simple `MH`
if it doesn't have replies when we are going to replace simple `MH`
* Wrap `MockMessageHandler` to the `Mockito.spy()` in the
`MockIntegration#mockMessageHandler()` to allow to `verify()` interaction
in the test-case
Remove wrapping `MockMH` to raw `MH` when no reply supported.
If `MockMH` isn't supplied with replies ti's safe to use it as is - no harm to target endpoint
which supposed to be last one in the flow
Some polishing and JavaDocs
More JavaDocs
Add docs for the `MockMessageHandler` and fix some JavaDocs
Make the `MockMessageHandler` with an API like:
```
MockIntegration.mockMessageHandler()
.handleNext(Consumer<Message<?>>)
.handleNext(Consumer<Message<?>>)
.handleNextAndReply(Function<Message<?>, Object>)
.handleNext(Consumer<Message<?>>)
.handleNextAndReply(Function<Message<?>, Object>)
.handleNextAndReply(Function<Message<?>, Object>);
```

MockIntegration PoC
Demonstrate how `MockIntegration.mockMessageSource()` can be used.
Even from the XML Config!
The same semantics can be applied for any other our mocking features we will add to the `MockIntegration`
Add `testMockMessageSourceDynamicFlow()`
Improve `MockIntegration.Context.instead()` for target bean type assertion
Some refactoring, improvements and JavaDocs
* Move `MockIntegration.Context` to its own `MockIntegrationContext` class
* Rename `@MockIntegrationTest` to `@SpringIntegrationTest` since we talk there not only about mocks, but any other possible testing feature for integration
* Add `@SpringIntegrationTest#stopEndpoints()` attribute for endpoints bean names patterns
* Add `IntegrationEndpointsInitializer` to customize `AbstractEndpoint`s according options from the `@SpringIntegrationTest`
Right now it is only about making them `autoStartup = false`
* Rename `SI-test` to `SI-test-support`
* Rename `SI-mock` to `SI-test`
* Rename `@SpringIntegrationTest#stopEndpoints()` to `noAutoStartup()`
* Fix JavaDocs according PR comments
* Increase timeouts in some sporadically failed tests
* Draft for the `testing.adoc`
Fixesspring-projects/spring-integration-java-dsl#23
Fix `testing.adoc` a bit
* Document Testing Support
* Fix a couple typos in the `xml.adoc`
* Add `package-info.java` files to `/test/` sub-packages
Improve docs according PR comments
Fix typos in `TestUtils` JavaDocs
Add `What's New` note about Java DSL and Testing support
