33b9bd72cc Proper support for Root WAC in Spring MVC Test
The modifications to DefaultMockMvcBuilder performed in conjunction
with SPR-12553 introduced a breaking change: the WebApplicationContext
supplied to DefaultMockMvcBuilder's constructor was *always* stored in
the ServletContext as the root WebApplicationContext, overwriting a
root WebApplicationContext that had been set by the user or by the
Spring TestContext Framework (TCF) -- for example, in
AbstractGenericWebContextLoader. Consequently, the changes in SPR-12553
cause tests that use @ContextHierarchy to fail if web components rely
on the correct WebApplicationContext being stored under the
WebApplicationContext#ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE key.

This commit reverts the breaking changes introduced in SPR-12553: if
the root WebApplicationContext has already been set in the
ServletContext of the WebApplicationContext supplied to
DefaultMockMvcBuilder, no action is taken.

Furthermore, this commit introduces new code to address the initial
intent of SPR-12553. Specifically, if the root WebApplicationContext
has NOT been set in the ServletContext of the WebApplicationContext
supplied to DefaultMockMvcBuilder, the application context hierarchy
will be traversed in search of the root WebApplicationContext, and the
root WebApplicationContext will then be stored under the
ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE key.

55eb5b622c Support XML config fully in web integration tests
Prior to this commit, it was impossible to use all features of XML
configuration (e.g., the <qualifier> tag) in web-based integration
tests (loaded using @WebAppConfiguration, @ContextConfiguration, etc.)
if the Groovy library was on the classpath. The reason is that the
GroovyBeanDefinitionReader used internally by
GenericGroovyXmlWebContextLoader disables XML validation for its
internal XmlBeanDefinitionReader, and this prevents some XML
configuration features from working properly. For example, the default
value for the 'type' attribute (defined in the spring-beans XSD) of the
<qualifier> tag gets ignored, resulting in an exception when the
application context is loaded.

This commit addresses this issue by refactoring the implementation of
loadBeanDefinitions() in GenericGroovyXmlWebContextLoader to use an
XmlBeanDefinitionReader or GroovyBeanDefinitionReader depending on the
file extension of the resource location from which bean definitions
should be loaded. This aligns the functionality of
GenericGroovyXmlWebContextLoader with the existing functionality of
GenericGroovyXmlContextLoader.

d98f626be1 Make TestPropertySourceUtils more robust
- Added assertions for pre-conditions on method arguments for all
   public utility methods.

 - Introduced additional tests in TestPropertySourceUtilsTests to verify
   the new pre-conditions.

 - Introduced INLINED_PROPERTIES_PROPERTY_SOURCE_NAME constant for the
   name of the MapPropertySource created from inlined properties; the
   name therefore no longer contains the inlined properties, but the
   original values of the inlined properties can now be logged at debug
   level.

 - Simplified tests in InlinedPropertiesTestPropertySourceTests.

e5d41d91d5 Preserve ordering of inlined props in @TestPropertySource
The initial implementation for adding inlined properties configured via
@TestPropertySource to the context's environment did not preserve the
order in which the properties were physically declared. This makes
@TestPropertySource a poor testing facility for mimicking the
production environment's configuration if the property source mechanism
used in production preserves ordering of property names -- which is the
case for YAML-based property sources used in Spring Boot, Spring Yarn,
etc.

This commit addresses this issue by ensuring that the ordering of
inlined properties declared via @TestPropertySource is preserved.
Specifically, the original functionality has been refactored. extracted
from AbstractContextLoader, and moved to TestPropertySourceUtils where
it may later be made public for general purpose use in other frameworks.

0c856b3d22 Support @Configuration as meta-annotation in the TCF
Spring Framework 4.0 introduced support for using test-related
annotations as meta-annotations in the Spring TestContext Framework
(TCF) in order to create custom composed annotations within a test
suite; however, the detection of default @Configuration classes in test
classes was not updated to search for @Configuration declared as a
meta-annotation. Specifically, AnnotationConfigContextLoaderUtils
invokes Class.isAnnotated() which only searches for annotations
declared directly on the class in question.

This commit addresses this issue by refactoring the
isDefaultConfigurationClassCandidate() method in
AnnotationConfigContextLoaderUtils so that it uses
AnnotationUtils.findAnnotation() instead of Class.isAnnotated() for
detecting the presence of the @Configuration annotation, either
directly or as a meta-annotation.

da04362a5e Log context cache statistics in the TCF
Prior to this commit, finding out how many application contexts had
been loaded within a test suite required the use of reflection and a
bit of hacking.

This commit addresses this issue by logging ContextCache statistics
whenever an application context is loaded by the Spring TestContext
Framework (TCF).

The log output can be enabled by setting the
"org.springframework.test.context.cache" logging category to DEBUG.

25d13ac41e Sensible defaults for Servlet & Filter registrations in mock
Prior to this commit, the getter methods in MockServletContext threw an
UnsupportedOperationException when trying to retrieve Servlet and
Filter registrations.

This commit improves the behavior of these methods by returning null
when a single registration is requested and an empty map when all
registrations are requested. This is now in line with the Javadoc for
ServletContext. Note, however, that the corresponding setter methods
still throw UnsupportedOperationExceptions which is suitable behavior
for a mock.

0b0ddc6ed1 Honor scheme in MockHttpServletRequest.isSecure()
Prior to this commit the implementation of isSecure() in
MockHttpServletRequest simply returned the value of the 'secure'
boolean flag. Thus setting the scheme to 'https' had no effect on the
value returned by isSecure() even though most non-mock implementations
(e.g., Tomcat, Jetty, etc.) base the return value on the actual scheme
in the request.

This commit makes the behavior of MockHttpServletRequest.isSecure()
more intuitive by honoring both the 'secure' boolean flag and the
current value of the scheme.

110be33337 Honor Host header for server name/port in MckHtSrvRq
Prior to this commit, the getServerName() and getServerPort() methods
in MockHttpServletRequest simply returned the 'mocked' serverName and
serverPort but ignored the 'Host' header entirely. Per the Servlet
specification, however, these methods must parse the server name or
port from the 'Host' header if it is present and otherwise fall back to
the resolved server name or port.

This commit fixes this by ensuring that getServerName() and
getServerPort() properly parse the server's name or port from the
'Host' header if it is present in the request. If the 'Host' header is
not present, MockHttpServletRequest falls back to returning the
'mocked' serverName and serverPort.

66250b1f8e Support merging custom TELs with default TELs
Prior to this commit, if a custom TestExecutionListener was registered
via @TestExecutionListeners the defaults would not be registered. Thus,
if a user wanted to declare a custom listener and use the default
listeners, the user was forced to manually declare all default
listeners in addition to any custom listeners. This unfortunately
required that the user know exactly which listeners were registered by
default. Moreover, the set of default listeners can change from release
to release, and with the support for automatic discovery of default
listeners introduced in SPR-11466 it is no longer even possible to know
what the set of default TestExecutionListeners is before runtime.

This commit addresses this issue by introducing a mechanism for merging
custom declared listeners with the defaults for the current
environment. Specifically, @TestExecutionListeners supports a new
MergeMode that is used to control whether or not explicitly declared
listeners are merged with the default listeners when
@TestExecutionListeners is declared on a class that does not inherit
listeners from a superclass.

e6d16148e5 Support automatic discovery of default TELs
Prior to this commit, there was no declarative mechanism for a custom
TestExecutionListener to be registered as a default
TestExecutionListener.

This commit introduces support for discovering default
TestExecutionListener implementations via the SpringFactoriesLoader
mechanism. Specifically, the spring-test module declares all core
default TestExecutionListeners under the
org.springframework.test.context.TestExecutionListener key in its
META-INF/spring.factories properties file, and third-party frameworks
and developers can contribute to the list of default
TestExecutionListeners in the same manner.

 - AbstractTestContextBootstrapper uses the SpringFactoriesLoader to
   look up the class names of all registered default
   TestExecutionListeners and sorts the instantiated listeners using
   AnnotationAwareOrderComparator.

 - DefaultTestContextBootstrapper and WebTestContextBootstrapper now
   rely on the SpringFactoriesLoader mechanism for finding default
   TestExecutionListeners instead of hard coding fully qualified class
   names.

 - To ensure that default TestExecutionListeners are registered in the
   correct order, each can implement Ordered or declare @Order.

 - AbstractTestExecutionListener and all default TestExecutionListeners
   provided by Spring now implement Ordered with appropriate values.

 - Introduced "copy constructors" in MergedContextConfiguration and
   WebMergedContextConfiguration

 - SpringFactoriesLoader now uses AnnotationAwareOrderComparator
   instead of OrderComparator.

181299cc6c Improve ex msg when locations & classes are declared in test hierarchy
Prior to this commit, if both locations and classes were declared via
@ContextConfiguration at differing levels in a test class hierarchy,
the exception message stated that neither of the default context
loaders was able to load an ApplicationContext from the merged context
configuration, but the message didn't explain why.

This commit adds an explicit check for such scenarios and provides a
more informative exception message similar to the following:

"Neither X nor Y supports loading an ApplicationContext from
[MergedContextConfiguration ...]: declare either 'locations' or
'classes' but not both."

2cf4147ba8 Introduce @TestPropertySource support in the TCF
Spring Framework 3.1 introduced an Environment abstraction with support
for hierarchical PropertySources that can be configured
programmatically as well as declaratively via the @PropertySource
annotation. However, prior to this commit, there was no way to
declaratively configure PropertySources in integration tests in the
Spring TestContext Framework (TCF).

This commit introduces declarative support for PropertySources in the
TCF via a new class-level @TestPropertySource annotation. This
annotation provides two options for declaring test property sources:

 - The 'locations' attribute allows developers to declare external
   resource locations for test properties files.

 - The 'properties' attribute allows developers to declare inlined
   properties in the form of key-value pairs.

Test properties files are added to the Environment before all other
property sources and can therefore override system and application
property sources. Similarly, inlined properties are added to the
Environment before all other property sources and can therefore
override system property sources, application property sources, and
test properties files.

Specifically, this commit introduces the following major changes:

 - Introduced @TestPropertySource annotation along with internal
   TestPropertySourceAttributes, MergedTestPropertySources, and
   TestPropertySourceUtils for working with test property sources
   within the TCF.

 - All TestContextBootstrappers have been modified to support the
   merged property resource locations and inlined properties from
   @TestPropertySource.

 - MergedContextConfiguration (and consequently the context caching
   key) is now additionally based on the merged property resource
   locations and inlined properties from @TestPropertySource. The same
   applies to WebMergedContextConfiguration.

 - AbstractContextLoader's prepareContext() method now adds
   PropertySources for all resource locations and inlined properties
   from the supplied MergedContextConfiguration to the Environment of
   the supplied ApplicationContext. All subclasses of
   AbstractGenericContextLoader and AbstractGenericWebContextLoader
   therefore automatically provide support for @TestPropertySource.

35c372f200 Support Groovy scripts in the TCF
Spring Framework 4.0 introduced first-class support for a Groovy-based
DSL for defining the beans for an ApplicationContext. However, prior to
this commit, the Spring TestContext Framework (TCF) did not provide any
out-of-the-box support for using Groovy scripts as path-based resource
locations when loading an application context for tests.

This commit addresses this issue by introducing first-class support for
using Groovy scripts to load the ApplicationContext for integration
tests managed by the TCF. Specifically, the following changes have been
made in the TCF to support Groovy scripts.

 - Introduced getResourceSuffixes() in AbstractContextLoader in order
   to support multiple resource suffixes in the default detection
   process. This feature is used by the new Groovy/Xml context loaders.

 - Introduced GenericGroovyXmlContextLoader and
   GenericGroovyXmlWebContextLoader which support both Groovy scripts
   and XML config files for loading bean definitions. Furthermore,
   these loaders support "-context.xml" and "Context.groovy" as
   resource suffixes when detecting defaults. Note that a default XML
   config file will be detected before a default Groovy script.

 - DelegatingSmartContextLoader and WebDelegatingSmartContextLoader now
   use reflection to choose between using GenericGroovyXmlContextLoader
   and GenericGroovyXmlWebContextLoader vs. GenericXmlContextLoader and
   GenericXmlWebContextLoader as their XML loaders, depending on
   whether Groovy is present in the classpath.

 - Groovy scripts can be configured via the 'locations' or 'value'
   attributes of @ContextConfiguration and can be mixed seamlessly with
   XML config files.

71b63cd972 Update MockMvcConfigurer support
This is a follow-up on the commit introducing MockMvcConfigurer:
c2b0fac852

This commit refines the MockMvcConfigurer contract to use (the new)
ConfigurableMockMvcBuilder hence not requiring downcasting to
AbstractMockMvcBuilder.

The same also no longer passes the "default" RequestBuilder which would
also require a downcast, but rather allows a RequestPostProcessor to be
returned so that a 3rd party framework or application can modify any
property of every performed MockHttpServletRequest.

To make this possible the new SmartRequestBuilder interface separates
request building from request post processing while the new
ConfigurableSmartRequestBuilder allows adding a RequestPostProcessor
to a MockMvcBuilder.

2e75adb04c Improve transaction management for @Sql scripts
Prior to this commit, the support for SQL script execution via @Sql
provided an algorithm for looking up a required
PlatformTransactionManager to use to drive transactions. However, a
transaction manager is not actually required for all testing scenarios.

This commit improves the transaction management support for @Sql so
that SQL scripts can be executed without a transaction if a transaction
manger is not present in the ApplicationContext. The updated algorithm
now supports the following use cases.

 - If a transaction manager and data source are both present (i.e.,
   explicitly specified via the transactionManager and dataSource
   attributes of @SqlConfig or implicitly discovered in the
   ApplicationContext based on conventions), both will be used.

 - If a transaction manager is not explicitly specified and not
   implicitly discovered based on conventions, SQL scripts will be
   executed without a transaction but requiring the presence of a data
   source. If a data source is not present, an exception will be thrown.

 - If a data source is not explicitly specified and not implicitly
   discovered based on conventions, an attempt will be made to retrieve
   it by using reflection to invoke a public method named
   getDataSource() on the transaction manager. If this attempt fails,
   an exception will be thrown.

 - If a data source can be retrieved from the resolved transaction
   manager using reflection, an exception will be thrown if the
   resolved data source is not the data source associated with the
   resolved transaction manager. This helps to avoid possibly
   unintended configuration errors.

 - If @SqlConfig.transactionMode is set to ISOLATED, an exception will
   be thrown if a transaction manager is not present.

628806e85b Introduce @SqlConfig for common SQL script config
Prior to this commit, @Sql provided attributes for configuring the
syntax of the referenced SQL scripts as well as exception handling and
transaction behavior; however, such configuration could not be reused
across @Sql declarations thus requiring developers to copy-and-paste
common configuration and resulting in unnecessary code duplication.

This commit addresses this issue by introducing a new @SqlConfig
annotation that can be used to declare common, global configuration for
SQL scripts that can be reused within a test class hierarchy.

 - Introduced top-level @SqlConfig annotation and extracted
   common configuration attributes from @Sql.

 - @SqlConfig can be used at the class level for common, global config
   or via the new 'config' attribute of @Sql for local config.

 - Introduced MergedSqlConfig as a holder for the merged values from
   local and global @SqlConfig instances. MergedSqlConfig also contains
   the logic for overriding global configuration with local
   configuration.

 - Refactored all attributes of @SqlConfig to be either of type String
   or custom enums in order to support overriding. Empty Strings or
   DEFAULT enum values imply the use of a default or inherited value.

f667e43ca2 Introduce programmatic tx mgmt in the TCF
Historically, Spring's JUnit 3.8 TestCase class hierarchy supported
programmatic transaction management of "test-managed transactions" via
the protected endTransaction() and startNewTransaction() methods in
AbstractTransactionalSpringContextTests.

The Spring TestContext Framework (TCF) was introduced in Spring 2.5 to
supersede the legacy JUnit 3.8 support classes; however, prior to this
commit the TCF has not provided support for programmatically starting
or stopping the test-managed transaction.

This commit introduces a TestTransaction class in the TCF that provides
static utility methods for programmatically interacting with
test-managed transactions. Specifically, the following features are
supported by TestTransaction and its collaborators.

 - End the current test-managed transaction.

 - Start a new test-managed transaction, using the default rollback
   semantics configured via @TransactionConfiguration and @Rollback.

 - Flag the current test-managed transaction to be committed.

 - Flag the current test-managed transaction to be rolled back.

Implementation Details:

 - TransactionContext is now a top-level, package private class.

 - The existing test transaction management logic has been extracted
   from TransactionalTestExecutionListener into TransactionContext.

 - The current TransactionContext is stored in a
   NamedInheritableThreadLocal that is managed by
   TransactionContextHolder.

 - TestTransaction defines the end-user API, interacting with the
   TransactionContextHolder behind the scenes.
