After some further discussion:
The MVC config simplifies ViewResolver configuration especially where
content negotiation view resolution is involved.
The configuration of the underlying view technology however is kept
completely separate. In the case of the MVC namespace, dedicated
top-level freemarker, velocity, and tiles namespace elements are
provided. In the case of the MVC Java config, applications simply
declare FreeMarkerConfigurer, VelocityConfigurer, or TilesConfigurer
beans respectively.
Issue: SPR-7093
Following the separation of FreeMarker/Velocity/TilesConfigurer-related
configuration via separate interface, simplify and streamline the
view registration helper classes which no longer have much difference
(most are UrlBasedViewResolver's).
Updates to Javadoc and tests.
Issue: SPR-7093
This change improves the support for auto-registration of FreeMarker,
Velocity, and Tiles configuration.
The configuration is now conditional not only based on the classpath
but also based on whether a FreeMarkerConfigurer for example is already
present in the configuration.
This change also introduces FreeMarker~, Velocity~, and
TilesWebMvcConfigurer interfaces for customizing each view technology.
The WebMvcConfigurer can still be used to configure all view resolvers
centrally (including FreeMarker, Velocity, and Tiles) without some
default conifguration, i.e. without the need to use the new
~WebMvcConfigurer interfaces until customizations are required.
Issue: SPR-7093
This commit improves and completes the initial MVC namespace
view resolution implementation. ContentNegotiatingViewResolver
registration is now also supported.
Java Config view resolution support has been added.
FreeMarker, Velocity and Tiles view configurers are registered
depending on the classpath thanks to an ImportSelector.
For both, a default configuration is provided and documented.
Issue: SPR-7093
This change adds a method within the ModelResultMatcher that will allow
a user to assert whether the returned Model has an attribute with a
field that has a specific error associated with it.
Issue: SPR-11971
This commit introduces unit tests that attempt to reproduce the problem
described in Spring Boot issue 885; however, the tests pass and
therefore do not confirm the reported problem.
See: https://github.com/spring-projects/spring-boot/issues/885
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.
- TransactionalTestExecutionListener now delegates to
TransactionContext completely for starting and ending transactions.
Issue: SPR-5079
Prior to this commit, the Spring TestContext Framework (TCF) was
compatible with JUnit 4.5 or higher.
This commit effectively raises the minimum version of JUnit that is
officially supported by the TCF to JUnit 4.9, thereby aligning with
similar upgrades made in the Spring Framework 4.0 release (i.e.,
upgrading minimum requirements on third-party libraries to versions
released mid 2010 or later).
Issue: SPR-11908
Prior to this commit, SQL script annotations and related classes in the
TestContext framework (TCF) were named DatabaseInitializer*. However,
these annotations are not used only for initialization and are
therefore misleading when used for cleaning up the database.
This commit refines the names of annotations and related classes for
configuring SQL scripts to be executed for integration tests in the TCF
as follows:
- @DatabaseInitializer -> @Sql
- @DatabaseInitializers -> @SqlGroup
- DatabaseInitializerTestExecutionListener -> SqlScriptsTestExecutionListener
A special thanks goes out to the following attendees of the Zurich
Hackergarten meeting last night for their collective brainstorming:
@aalmiray, @atsticks, @ollin, @simkuenzi, @tangresh, @vyazelenko.
Issue: SPR-7655
Prior to this commit, it was possible to execute SQL scripts
programmatically via ResourceDatabasePopulator, JdbcTestUtils, and
ScriptUtils. Furthermore, it was also possible to execute SQL scripts
declaratively via the <jdbc> XML namespace. However, it was not
possible to execute SQL scripts declaratively on a per test class or
per test method basis.
This commit makes it possible to declaratively configure SQL scripts
for execution in integration tests via annotations that can be declared
at the class or method level. Details follow.
- Introduced a repeatable @DatabaseInitializer annotation that can be
used to configure SQL scripts at the class or method level with
method-level overrides. @DatabaseInitializers serves as a container
for @DatabaseInitializer.
- Introduced a new DatabaseInitializerTestExecutionListener that is
responsible for parsing @DatabaseInitializer and
@DatabaseInitializers and executing SQL scripts.
- DatabaseInitializerTestExecutionListener is registered by default in
abstract base test classes as well as in TestContextBootstrapper
implementations.
- @DatabaseInitializer and @DatabaseInitializers may be used as
meta-annotations; however, attribute overrides are not currently
supported for repeatable annotations used as meta-annotations. This
is a known limitation of Spring's AnnotationUtils.
- The semantics for locating SQL script resources is consistent with
@ContextConfiguration's semantics for locating XML configuration
files. In addition, a default SQL script can be detected based
either on the name of the annotated class or on the name of the
annotated test method.
- @DatabaseInitializer allows for specifying which DataSource and
PlatformTransactionManager to use from the test's
ApplicationContext, including default conventions consistent with
TransactionalTestExecutionListener and @TransactionConfiguration.
- @DatabaseInitializer supports all of the script configuration options
currently supported by ResourceDatabasePopulator.
- @DatabaseInitializer and DatabaseInitializerTestExecutionListener
support execution phases for scripts that dictate when SQL scripts
are executed (i.e., before or after a test method).
- SQL scripts can be executed within the current test's transaction if
present, outside of the current test's transaction if present, or
always in a new transaction, depending on the value of the boolean
requireNewTransaction flag in @DatabaseInitializer.
- DatabaseInitializerTestExecutionListener delegates to
ResourceDatabasePopulator#execute to actually execute the scripts.

This commit upgrades Hibernate-based integration tests in the
spring-test module to use Hibernate 4 instead of 3 and Hibernate
Validator 5 instead of 4. This streamlines and simplifies our
dependency management at the same time.
Issue: SPR-11834
Work done in conjunction with SPR-5243 and SPR-4588 introduced physical
package cycles in the spring-test module. The work performed in
conjunction with SPR-9924 uses reflection to resolve these physical
package cycles; however, prior to this commit the logical package
cycles still remain.
Furthermore, over time it has become apparent that the Spring
TestContext Framework (TCF) could better serve application developers
and especially third-party framework developers by providing a more
flexible mechanism for "bootstrapping" the TCF. For example, prior to
this commit, default TestExecutionListeners could only be registered by
subclassing TestContextManager (and SpringJUnit4ClassRunner if using
JUnit). Similarly, the default ContextLoader could only be set by
subclassing SpringJUnit4ClassRunner for JUnit and by copying and
modifying AbstractTestNGSpringContextTests for TestNG.
This commit addresses the aforementioned issues by introducing a
bootstrap strategy in the TestContext framework that is responsible for
determining default TestExecutionListeners and the default
ContextLoader in an extensible fashion. The new TestContextBootstrapper
SPI also provides a mechanism for supporting various types of
MergedContextConfiguration depending on the feature set of the context
loaders supported by the strategy.
The following provides an overview of the most significant changes in
this commit.
- Introduced TestContextBootstrapper strategy SPI, BootstrapContext,
and @BootstrapWith.
- Introduced AbstractTestContextBootstrapper,
DefaultTestContextBootstrapper, and WebTestContextBootstrapper
implementations of the TestContextBootstrapper SPI and extracted
related reflection code from ContextLoaderUtils & TestContextManager.
- Introduced BootstrapUtils for retrieving the TestContextBootstrapper
from @BootstrapWith, falling back to a default if @BootstrapWith is
not present.
- @WebAppConfiguration is now annotated with
@BootstrapWith(WebTestContextBootstrapper.class).
- CacheAwareContextLoaderDelegate is now an interface with a new
DefaultCacheAwareContextLoaderDelegate implementation class.
- Introduced closeContext(MergedContextConfiguration, HierarchyMode) in
CacheAwareContextLoaderDelegate.
- DefaultTestContext now uses CacheAwareContextLoaderDelegate instead
of interacting directly with the ContextCache.
- DefaultTestContext now delegates to a TestContextBootstrapper for
building the MergedContextConfiguration.
- TestContextManager now delegates to TestContextBootstrapper for
retrieving TestExecutionListeners.
- Deleted TestContextManager(Class, String) constructor and
SpringJUnit4ClassRunner.getDefaultContextLoaderClassName(Class)
method since default ContextLoader support is now implemented by
TestContextBootstrappers.
- Extracted ActiveProfilesUtils from ContextLoaderUtils.
- Extracted ApplicationContextInitializerUtils from ContextLoaderUtils.
- MetaAnnotationUtils is now a public utility class in the test.util
package.
- Removed restriction in @ActiveProfiles that a custom resolver cannot
be used with the 'value' or 'profiles' attributes.
- Introduced DefaultActiveProfilesResolver.
Issue: SPR-9955
This commit introduces an explicit integration test to verify that a
PropertySource can be set via a custom ApplicationContextInitializer in
the Spring TestContext Framework.
Issue: SPR-11666
Prior to this commit, the Spring TestContext Framework did not support
the declaration of both 'locations' and 'classes' within
@ContextConfiguration at the same time.
This commit addresses this in the following manner:
- ContextConfigurationAttributes no longer throws an
IllegalArgumentException if both 'locations' and 'classes' are
supplied to its constructor.
- Concrete SmartContextLoader implementations now validate the
supplied MergedContextConfiguration before attempting to load the
ApplicationContext. See validateMergedContextConfiguration().
- Introduced tests for hybrid context loaders like the one used in
Spring Boot. See HybridContextLoaderTests.
- Updated the Testing chapter of the reference manual so that it no
longer states that locations and classes cannot be used
simultaneously, mentioning Spring Boot as well.
- The Javadoc for @ContextConfiguration has been updated accordingly.
- Added hasLocations(), hasClasses(), and hasResources() convenience
methods to MergedContextConfiguration.
Issue: SPR-11634
To simplify common use cases, this commit introduces a new
execute(DataSource) method in ResourceDatabasePopulator that complements
the existing populate(Connection) method.
Issue: SPR-11629
Prior to this commit, if multiple test methods were executed in a
subclass of AbstractTestNGSpringContextTests annotated with
@WebAppConfiguration, then injected Servlet API mocks would only
reference the mocks created for the first test method. Subsequent test
methods could therefore never reference the current mocks, and there
was a discrepancy between the state of the injected mocks and the mock
set in the RequestContextHolder.
This commit addresses this issue by ensuring that dependencies
(including updated mocks) are injected into the test instance before
the next test method if the ServletTestExecutionListener resets the
request attributes in RequestContextHolder.
