Starting with Spring 3.1 applications can specify
contextInitializerClasses via context-param and init-param in web.xml;
however, there is currently no way to have such initializers invoked in
integration testing scenarios without writing a custom
SmartContextLoader. For comprehensive integration testing it should
therefore be possible to re-use ApplicationContextInitializers in the
Spring TestContext Framework as well.
This commit makes this possible at the @ContextConfiguration level by
allowing an array of ACI types to be specified, and the out-of-the-box
SmartContextLoader implementations invoke the declared initializers at
the appropriate time.
- Added initializers and inheritInitializers attributes to
@ContextConfiguration.
- Introduced support for ApplicationContextInitializers in
ContextConfigurationAttributes, MergedContextConfiguration, and
ContextLoaderUtils.
- MergedContextConfiguration stores context initializer classes as a
Set and incorporates them into the implementations of hashCode() and
equals() for proper context caching.
- ApplicationContextInitializers are invoked in the new
prepareContext(GenericApplicationContext, MergedContextConfiguration)
method in AbstractGenericContextLoader, and ordering declared via the
Ordered interface and @Order annotation is honored.
- Updated DelegatingSmartContextLoader to support initializers.
Specifically, a test class may optionally declare neither XML
configuration files nor annotated classes and instead declare only
application context initializers. In such cases, an attempt will
still be made to detect defaults, but their absence will not result
an an exception.
- Documented support for application context initializers in Javadoc
and in the testing chapter of the reference manual.

The invalidate() method in MockHttpSession is currently implemented
incorrectly. According to the Servlet specification, the method should
throw an IllegalStateException if it is invoked on an already
invalidated session. However, invoking invalidate() on the same
MockHttpSession instance multiple times does not throw an exception.
This commits addresses this issue by checking the invalid field and
throwing an IllegalStateException if it has already been set to true.
Issue: SPR-9686
ReflectionTestUtils.setField() implicitly calls toString() on the target
object when arguments for a call to Assert.notNull() are built. This can
have undesirable side effects, for example if the toString() invocation
results in a thrown exception or access to an external system (e.g., a
database).
This commit addresses this issue by inlining the Assert.notNull() code,
thereby avoiding accidental invocation of toString() on a non-null
target.
Issue: SPR-9571
The default set of TestExecutionListeners is sufficient in most
integration testing scenarios; however, the TestContextManager
nonetheless logs an INFO message if the @TestExecutionListeners
annotation is not present on an integration test class.
In order to avoid flooding the logs with messages about the absence of
@TestExecutionListeners, this commit reduces the log level for such
messages from INFO to DEBUG.
Issue: SPR-8645
Recently new utility methods were added to JdbcTestUtils, and a
JdbcTemplate was introduced in abstract transactional base classes in
the TestContext framework. This presents an easy opportunity to make
these new utility methods available as convenience methods in the base
test classes.
This commit introduces new countRowsInTableWhere() and dropTables()
convenience methods in the abstract transactional base classes in the
TestContext framework. These new methods internally delegate to methods
of the same names in JdbcTestUtils.
Issue: SPR-9665
Since Spring 2.5, the abstract transactional base classes in the
TestContext framework have defined and delegated to a protected
SimpleJdbcTemplate instance variable; however, SimpleJdbcTemplate has
deprecated since Spring 3.1. Consequently, subclasses of
AbstractTransactionalJUnit4SpringContextTests and
AbstractTransactionalTestNGSpringContextTests that use this instance
variable suffer from seemingly unnecessary deprecation warnings.
This commit addresses this issue by introducing a protected JdbcTemplate
instance variable in abstract transactional base classes to replace the
use of the existing SimpleJdbcTemplate. Furthermore, the existing
simpleJdbcTemplate instance variable has been deprecated, and utility
methods in the affected base classes now delegate to JdbcTestUtils
instead of the now deprecated SimpleJdbcTestUtils.
Issue: SPR-8990
Several static utility methods in SimpleJdbcTestUtils accept an instance
of SimpleJdbcTemplate as an argument; however, SimpleJdbcTemplate has
been deprecated since Spring 3.1 in favor of simply using JdbcTemplate
which now also supports Java 5 language constructs such as var-args.
Consequently, use of such methods from SimpleJdbcTestUtils results in
deprecation warnings without an equivalent API to migrate to.
This commit addresses this issue by migrating all existing methods in
SimpleJdbcTestUtils to JdbcTestUtils. The migrated methods now accept an
instance of JdbcTemplate as an argument, thereby avoiding the
deprecation warnings but maintaining semantic compatibility with the
functionality previous available in SimpleJdbcTestUtils.
In addition, this commit also introduces two new methods:
- countRowsInTableWhere(): counts the rows in a given table, using
a provided `WHERE` clause
- dropTables(): drops the tables with the specified names
Issue: SPR-9235
For legacy reasons, a MockEnvironment implementation already exists in multiple places within Spring's test suite; however, it is not available to the general public.
This commit promotes MockEnvironment to a first-class citizen in the spring-test module, alongside the existing MockPropertySource.
In addition, the following house cleaning has been performed.
- deleted MockPropertySource from the spring-expression module
- deleted MockEnvironment from the "spring" integration testing module
- updated test copies of MockPropertySource and MockEnvironment
- documented MockEnvironment and MockPropertySource in the testing
chapter of the reference manual
Issue: SPR-9492
Currently the Spring TestContext Framework looks up a
PlatformTransactionManager bean named "transactionManager". The exact
name of the bean can be overridden via @TransactionConfiguration or
@Transactional; however, the bean will always be looked up 'by name'.
The TransactionManagementConfigurer interface that was introduced in
Spring 3.1 provides a programmatic approach to specifying the
PlatformTransactionManager bean to be used for annotation-driven
transaction management, and that bean is not required to be named
"transactionManager". However, as of Spring 3.1.2, using the
TransactionManagementConfigurer on a @Configuration class has no effect
on how the TestContext framework looks up the transaction manager.
Consequently, if an explicit name or qualifier has not been specified,
the bean must be named "transactionManager" in order for a transactional
integration test to work.
This commit addresses this issue by refactoring the
TransactionalTestExecutionListener so that it looks up and delegates to
a single TransactionManagementConfigurer as part of the algorithm for
determining the transaction manager.
Issue: SPR-9604
TransactionalTestExecutionListener currently requires that the
PlatformTransactionManager bean be named "transactionManager" by
default. Otherwise, the bean name can only be overridden via the
transactionManager attribute of @TransactionConfiguration or the value
attribute of @Transactional.
However, if there is only a single PlatformTransactionManager in the
test's ApplicationContext, then the requirement to specify the exact
name of that bean (or to name it exactly "transactionManager") is often
superfluous.
This commit addresses this issue by refactoring the
TransactionalTestExecutionListener so that it is comparable to the
algorithm for determining the transaction manager used in
TransactionAspectSupport for "production" code. Specifically, the TTEL
now uses the following algorithm to retrieve the transaction manager.
- look up by type and qualifier from @Transactional
- else, look up by type and explicit name from
@TransactionConfiguration
- else, look up single bean by type
- else, look up by type and default name from @TransactionConfiguration
Issue: SPR-9645
Currently the getNamedDispatcher(String) method of MockServletContext
always returns null. This poses a problem in certain testing scenarios
since one would always expect at least a default Servlet to be present.
This is specifically important for web application tests that involve
the DefaultServletHttpRequestHandler which attempts to forward to the
default Servlet after retrieving it by name. Furthermore, there is no
way to register a named RequestDispatcher with the MockServletContext.
This commit addresses these issues by introducing the following in
MockServletContext.
- a new defaultServletName property for configuring the name of the
default Servlet, which defaults to "default"
- named RequestDispatchers can be registered and unregistered
- a MockRequestDispatcher is registered for the "default" Servlet
automatically in the constructor
- when the defaultServletName property is set to a new value the
the current default RequestDispatcher is unregistered and replaced
with a MockRequestDispatcher for the new defaultServletName
Issue: SPR-9587
Previously MockHttpServletRequest#sendRedirect did not set the HTTP status
or the Location header. This does not conform to the HttpServletRequest
interface.
MockHttpServletRequest will now:
- Set the HTTP status to 302 on sendRedirect
- Set the Location header on sendRedirect
- Ensure the Location header and getRedirectedUrl are kept in synch
Issue: SPR-9594
This commit introduces a test suite (Spr8849Tests) that demonstrates
the claims made in SPR-8849.
Specifically, if <jdbc:embedded-database id="xyz" /> is used to create
an embedded HSQL database in an XML configuration file and that
configuration file is imported in different sets of configuration files
that are used to load ApplicationContexts for different integration
tests, the embedded database will be initialized multiple times using
any nested <jdbc:script /> elements. If such a script is used to create
a table, for example, subsequent attempts to initialize the database
named "xyz" will fail since an embedded database named "xyz" already
exists in the JVM.
As a work-around, this test suite uses a SpEL expression to generate a
random string for each embedded database instance:
id="#{T(java.util.UUID).randomUUID().toString()}"
See the Javadoc in Spr8849Tests for further information.

Commit 096693c46f refactored and
deprecated TransactionAspectUtils, moving its #qualifiedBeanOfType
and related methods into BeanFactoryUtils. This created a package cycle
between beans.factory and beans.factory.annotation due to use of the
beans.factory.annotation.Qualifier annotation in these methods.
This commit breaks the package cycle by introducing
beans.factory.annotation.BeanFactoryAnnotationUtils and moving these
@Qualifier-related methods to it. It is intentionally similar in name
and style to the familiar BeanFactoryUtils class for purposes of
discoverability.
There are no backward-compatibilty concerns associated with this change
as the cycle was introduced, caught and now fixed before a release.
Issue: SPR-6847
TransactionAspectUtils contains a number of methods useful in
retrieving a bean by type+qualifier. These methods are functionally
general-purpose save for the hard coding of PlatformTransactionManager
class literals throughout.
This commit generifies these methods and moves them into
BeanFactoryUtils primarily in anticipation of their use by async method
execution interceptors and aspects when performing lookups for qualified
executor beans e.g. via @Async("qualifier").
The public API of TransactionAspectUtils remains backward compatible;
all methods within have been deprecated, and all calls to those methods
throughout the framework refactored to use the new BeanFactoryUtils
variants instead.
The reference manual previously did not mention the applicability of
JSR-250 lifecycle annotations within the TestContext framework. The
lacking documentation here has lead to misunderstandings of the support
provided for @PostConstruct and @PreDestroy in test classes.
The testing chapter of the reference manual has therefore been updated
to explicitly define the limited support for these annotations.
Also introduced Jsr250LifecycleTests for empirical verification of the
expected behavior.
Issue: SPR-4868
Introduced AtBeanLiteModeScopeTests integration tests to verify proper
scoping of beans created in 'lite' mode.
Updated comments in TACCWithoutACTests to better reflect the runtime
behavior for 'lite' @Bean methods.
Issue: SPR-9401
Updated all Javadoc in the Spring TestContext Framework (TCF) to explain
and refer to 'annotated classes' instead of 'configuration classes'.
Specifically, @ContextConfiguration now explicitly defines what is meant
by 'annotated classes', and various other classes now refer to this
definition. Otherwise, the term 'configuration class' has simply been
replaced with 'annotated class'.
Also deleted cross references to deprecated JUnit 3.8 classes and
formatted Javadoc in general for greater readability.
Issue: SPR-9401
AbstractTransactionalAnnotatedConfigClassTests is now annotated with
@DirtiesContext(classMode = ClassMode.AFTER_EACH_TEST_METHOD) so
that side-effects between tests are avoided.
Re-enabled TransactionalAnnotatedConfigClassWithAtConfigurationTests
and TransactionalAnnotatedConfigClassesWithoutAtConfigurationTests.
Also introduced a log4j FileAppender for tests that writes to
"build/spring-test.log".
Issue: SPR-9051
The claim: given an integration test class that is annotated with
@ContextConfiguration and declares a configuration class that is missing
an @Configuration annotation, if a transactional test method (i.e., one
annotated with @Transactional) changes the state of the database then
the
changes will not be rolled back as would be expected with the default
rollback semantics of the Spring TestContext Framework (TCF).
TransactionalAnnotatedConfigClassWithAtConfigurationTests is a concrete
implementation of AbstractTransactionalAnnotatedConfigClassTests that
uses
a true @Configuration class and thereby demonstrates the expected
behavior
of such transactional tests with automatic rollback.
TransactionalAnnotatedConfigClassesWithoutAtConfigurationTests is a
concrete implementation of
AbstractTransactionalAnnotatedConfigClassTests
that does NOT use a true @Configuration class but rather a 'lite mode'
configuration class (see the Javadoc for @Bean for details).
Using such a 'lite mode' configuration class results in the following:
- Its @Bean methods act as factory methods instead of singleton beans.
- The dataSource() method is invoked multiple times instead of once.
- The test instance and the TCF operate on different data sources.
- The transaction managed (and rolled back) by the TCF is not the
transaction that the application code or test instance uses.
Ultimately, the use of a 'lite mode' configuration class gives the false
appearance that there is a bug in the TCF (in that the transaction is
not
rolled back); however, the transaction managed by the TCF is in fact
rolled back.
In conclusion, these tests demonstrate both the intended behavior of the
TCF and the fact that using 'lite mode' configuration classes can lead
to
confusing results (both in tests and production code).
Issue: SPR-9051
It was claimed that when a {@code @ContextConfiguration} test class
references a config class missing an {@code @Configuration} annotation,
@Bean dependencies are wired successfully but the bean lifecycle is not
applied (no init methods are invoked, for example).
AnnotatedConfigClassesWithoutAtConfigurationTests refutes this claim by
demonstrating that @Bean methods in non-@Configuration classes are
properly handled as "annotated factory bean methods" and that lifecycle
callbacks in fact apply to such factory beans.
Issue: SPR-9051
Two tests in MockServletContextTests were disabled with @Ignore with the
comment "fails to work under ant after move from .testsuite -> .test";
however, this no longer appears to apply with the Gradle build. Thus
these tests have been re-enabled.
Before this change there were numerous javadoc warnings being reported
while building Spring framework API.
This commit resolves most of the javadoc warnings, reducing the total
number from 265 to 103.
Issue: SPR-9113
Before this change javadoc in two classes had non-UTF-8 encoded
characters. This caused building Spring API to fail in Java 1.7.
Commit fixes this by replacing wrongly encoded characters with their
UTF-8 equivalents.
Issue: SPR-9097
Each of these tests began failing during the Gradle build porting
process. None seem severe, many are likely due to classpath issues.
In the case of TestNG support, this needs to be added to the Gradle
build in order to execute these tests. See SPR-8116.txt
This renaming more intuitively expresses the relationship between
subprojects and the JAR artifacts they produce.
Tracking history across these renames is possible, but it requires
use of the --follow flag to `git log`, for example
$ git log spring-aop/src/main/java/org/springframework/aop/Advisor.java
will show history up until the renaming event, where
$ git log --follow spring-aop/src/main/java/org/springframework/aop/Advisor.java
will show history for all changes to the file, before and after the
renaming.
