Whereas the existing TestContextConcurrencyTests verify support for
concurrency in the TestContextManager and TestContext, this commit
introduces SpringJUnit4ConcurrencyTests that verify support for
concurrent test execution in Spring's JUnit 4 support, namely in the
SpringRunner, SpringClassRule, and SpringMethodRule.
The tests executed by this new test class come from a hand-picked
collection of test classes within the test suite that is intended to
cover most categories of tests that are currently supported by the
TestContext Framework on JUnit 4.
Note, however, that the chosen test classes intentionally do not
include any classes that fall under the following categories.
- tests that make use of Spring's @DirtiesContext support
- tests that make use of JUnit 4's @FixMethodOrder support
- tests that commit changes to the state of a shared in-memory database
Issue: SPR-5863
Prior to this commit, executing tests concurrently in the TestContext
Framework (TCF) was unsupported and typically lead to unpredictable
results.
This commit addresses this core issue by supporting concurrent
execution in the TestContextManager and the DefaultTestContext.
Specifically, the TestContextManager now uses ThreadLocal storage for
the current TestContext, thereby ensuring that any registered
TestExecutionListeners and the TestContextManager itself operate on a
TestContext specific to the current thread.
In order to avoid repeatedly incurring the costs of the overhead of the
TCF bootstrapping process, the original TestContext built by the
TestContextBootstrapper is used as a template which is then passed to
the copy constructor of the concrete implementation of the TestContext
to create the context for the current thread. DefaultTestContext now
implements such a copy constructor, and all concrete implementations of
TestContext are encouraged to do the same.
If the TestContext built by the TestContextBootstrapper does not
provide a copy constructor, thread-safety and support for concurrency
are left completely to the implementation of the concrete TestContext.
Note, however, that this commit does not address any thread-safety or
concurrency issues in the ContextLoader SPI or its implementations.

This commit introduces integration tests that verify the expected
behavior for @Nested tests in conjunction with the SpringExtension for
JUnit Jupiter, including automatic application of
TestExecutionListeners to the enclosing test instance of a @Nested
test instance.
Issue: SPR-14150
Due to restrictions imposed by JUnit 4, the SpringClassRule must be
declared as a public static field, which makes it impossible to be
declared directly within a nested (i.e., inner) test class.
This commit demonstrates a work-around that makes it possible to use
the SpringClassRule and SpringMethodRule in a nested (i.e., inner) test
class when using a custom JUnit 4 runner such as the
HierarchicalContextRunner from Stefan Bechtold.
The trick is to have inner test classes extend a class that properly
declares the SpringClassRule and SpringMethodRule. The
SpringRuleConfigurer in this commit serves as an example.
Note, however, that each such nested test class must declare its own
@ContextConfiguration. Furthermore, TestExecutionListeners in the
Spring TestContext Framework are not applied to the enclosing instance
of such an inner test class, meaning that @Autowired fields in the
enclosing instance will not be injected, etc.

This commit picks up where SPR-14614 left off by introducing a new
@EnabledIf annotation to serve as a logical companion to @DisabledIf.
In addition, this commit extracts common logic from DisabledIfCondition
into a new AbstractExpressionEvaluatingCondition base class which the
new EnabledIfCondition also extends.
An @EnabledOnMac annotation is also included in the Javadoc as well as
in the test suite to demonstrate support for custom composed annotations.
Issue: SPR-14644
Prior to this commit, the DisabledIfCondition did not trim whitespace
from expressions configured via @DisabledIf. Consequently, results such
as " true " would evaluate to "false".
This commit fixes this problem by trimming all expressions configured
via @DisabledIf.
Issue: SPR-14614
This commit introduces tests for DisabledIfCondition that verify actual
condition evaluation results and exception handling; whereas, the
existing tests in DisabledIfTestCase only test the "happy paths" and
standard cases.
Issue: SPR-14614
- Extracted stand-alone DisabledIfCondition from the SpringExtension
so that the condition is only evaluated when necessary.
- Simplified implementation of DisabledIfCondition.
- Overhauled and extended logging in DisabledIfCondition.
- DisabledIfCondition now throws an IllegalStateException if @DisabledIf
is not present on the test element or if the expression does not
evaluate to a String or Boolean.
- Each generated ConditionEvaluationResult now includes the actual
expression in the default reason.
- @DisabledIf is now auto-configured to be evaluated by the
DisabledIfCondition since it is now meta-annotated with
@ExtendWith(DisabledIfCondition.class)
- Overhauled documentation for @DisabledIf and provided standard
examples as well as an @DisabledOnMac annotation to demonstrate
support for custom composed annotations.
Issue: SPR-14614
This commit introduces @DisabledIf annotation that takes SpEL as a
condition. The condition is evaluated at run time whether to disable
JUnit 5 (Jupiter) test method/class.

This change adds support for a target type in JsonPath assertions in
Spring MVC Test.
The existing assertValue(String expression, Object expectedValue)
transparently falls back on using an alternative JsonPath API that
allows specifying the target type to coerce to.
There is also a new overloaded method
assertValue(String expression, Matcher<T> matcher, Class<T> targetType)
for use with Hamcrest matchers where the target type can be specified.
Issue: SPR-14498
Previously invoking HtmlUnitRequestBuilder merge caused the pathInfo of
the parent to be corrupted. This could additional invocations with the
same parent.
This fix ensures that the parent is no longer directly used. Instead,
we create a copy of the parent by merging the parent that was passed in
with the copy.
Fixes SPR-14584
Prior to this commit, a dynamic test in
FailingBeforeAndAfterMethodsSpringExtensionTestCase was failing but for
the wrong reason. Namely, the @Configuration class was private which
resulted in an IllegalStateException being thrown, when in fact
an AssertionFailedError was expected.
This commit addresses this by introducing an explicit check for an
AssertionFailedError.
Issue: SPR-4365
Prior to this commit, if multiple TestExecutionListener 'after' methods
threw an exception, only the first such exception was rethrown.
Subsequent exceptions were logged, but there was no way to access or
process them other than via the log file.
This commit addresses this shortcoming by making use of the support for
suppressed exceptions introduced in Java 7. Specifically, if multiple
TestExecutionListener 'after' methods throw an exception, the first
exception will be rethrown with subsequent exceptions suppressed in the
first one.
Issue: SPR-14459
This commit introduces initial support for JUnit Jupiter (i.e., the new
programming and extension models in JUnit 5) in the Spring TestContext
Framework.
Specifically, this commit introduces the following.
- SpringExtension: an implementation of multiple extension APIs from
JUnit Jupiter that provides full support for the existing feature set
of the Spring TestContext Framework. This support is enabled via
@ExtendWith(SpringExtension.class).
- @SpringJUnitConfig: a composed annotation that combines
@ExtendWith(SpringExtension.class) from JUnit Jupiter with
@ContextConfiguration from the Spring TestContext Framework.
- @SpringJUnitWebConfig: a composed annotation that combines
@ExtendWith(SpringExtension.class) from JUnit Jupiter with
@ContextConfiguration and @WebAppConfiguration from the Spring
TestContext Framework.
Issue: SPR-13575
Prior to this commit, any attempt to include a bean of type
ServletServerContainerFactoryBean in the WebApplicationContext for an
integration test class annotated with @WebAppConfiguration in
conjunction the Spring TestContext Framework (TCF) would have resulted
in an IllegalStateException stating that "A ServletContext is required
to access the javax.websocket.server.ServerContainer instance."
In such scenarios, the MockServletContext was in fact present in the
WebApplicationContext; however there was no WebSocket ServerContainer
stored in the ServletContext.
This commit addresses this issue by introducing the following.
- MockServerContainer: a private mock implementation of the
javax.websocket.server.ServerContainer interface.
- MockServerContainerContextCustomizer: a ContextCustomizer that
instantiates a new MockServerContainer and stores it in the
ServletContext under the attribute named
"javax.websocket.server.ServerContainer".
- MockServerContainerContextCustomizerFactory: a
ContextCustomizerFactory which creates a
MockServerContainerContextCustomizer if WebSocket support is present
in the classpath and the test class is annotated with
@WebAppConfiguration. This factory is registered by default via the
spring.factories mechanism.
Issue: SPR-14367
ReflectionTestUtils invokes toString() on target objects in order to
build exception and logging messages, and prior to this commit problems
could occur if the invocation of toString() threw an exception.
This commit addresses this issue by ensuring that all invocations of
toString() on target objects within ReflectionTestUtils are performed
safely within try-catch blocks.
Issue: SPR-14363
Previously MockMvcWebConnection did not update the cookie manager with the
cookies from MockHttpServletResponse. This meant that newly added cookies
are not saved to the cookie manager and thus are not presented in the next
request.
This commit ensures that MockMvcWebConnection stores the response cookies
in the cookie manager.
