This commit introduces the `DispatcherServletCustomizer` callback
interface that can be used to customize the `DispatcherServlet` that a
`MockMvc` is using.
Previously, only the `dispatchOptions` flag can be customized. This
commit allows to customize any property of `DispatcherServlet` before it
is initialized.

Prior to this commit, when using @EnabledIf or @DisabledIf in Spring's
JUnit Jupiter support, the test's ApplicationContext was always eagerly
loaded, even if the ApplicationContext would never be used (i.e., the
test was disabled). This behavior can lead to undesirable side effects
-- for example, attempting to load an application context that requires
services only available on the CI server when the test is not actually
running on the CI server.
This commit addresses this issue by introducing new boolean
`loadContext` flags in @EnabledIf and @DisabledIf. By default these
flags are set to false which means that the user's test application
context will not be loaded to evaluate the expression. On the contrary,
a dummy application context will be loaded instead, and expressions
will be evaluated against that dummy context. Consequently, if the user
wishes to interact with properties from the Spring Environment or with
beans from the test application context, the `loadContext` must be
explicitly set to true.
In addition, expressions which evaluate to a String must now evaluate
to exactly "true" or "false" (ignoring case and surrounding whitespace).

Prior to this commit, the redirectedUrl() and forwardedUrl() methods in
MockMvcResultMatchers supported fully constructed URLs and URLs
containing Ant-style path patterns. However, URI templates were not
supported for these result matchers even though the request path can be
built using URL templates -- for example, via the get() and post()
methods in MockMvcRequestBuilders.
This commit addresses this shortcoming by allowing users to supply a
URL template instead of a fully constructed URL to redirectedUrl() and
forwardedUrl(). To populate the URL template, template variables may be
supplied to redirectedUrl() and forwardedUrl() as var-args.

Commit e65a1a4372 introduced support in PrintingResultHandler for only
printing the request or response body in the Spring MVC Test framework
if the content type is known to be text-based (e.g., plain text, HTML,
XHTML, XML, JSON, etc.). For unknown content types the body is assumed
to be text-based and is therefore always printed. The latter behavior,
however, is undesirable since the content may in fact not be text-based.
This commit addresses this issue by making the printing of the request
or response body an opt-in feature. Specifically, if a character
encoding has been set, the request or response body will be printed by
the PrintingResultHandler. Note, however, that the character encoding
is set to ISO-8859-1 in MockHttpServletResponse by default.
In addition, MockHttpServletRequest's getContentAsString() method now
throws an IllegalStateException if the character encoding has not been
set.
Issue: SPR-14776
Prior to this commit, PrintingResultHandler always printed the request
or response body regardless of its content type. For binary content,
however, the output was unreadable and therefore useless.
This commit addresses this issue by only printing the request or
response body if it is "printable" (i.e., if its content type is known
to be text-based such as plain text, HTML, XHTML, XML, JSON, etc.). If
the content type is unknown (e.g., unspecified for the HTTP request in
the test), it is assumed that the body is printable.
Issue: SPR-14776
Prior to this commit, the PrintingResultHandler used by the various
print() and log() methods in Spring MVC Test printed the response body
but not the request body.
Since request bodies are sometimes generated programmatically, however,
it can be beneficial to have the dynamically generated request body
logged as well.
This commit therefore prints the request body in PrintingResultHandler
by delegating to the recently introduced getContentAsString() method in
MockHttpServletRequest.
Issue: SPR-14717
In order to improve debugging and logging within test suites, this
commit introduces getContentAsByteArray() and getContentAsString()
methods in MockHttpServletRequest, analogous to the existing methods in
MockHttpServletResponse.
Issue: SPR-14717
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.
Issue: SPR-5863
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.
Issue: SPR-14150
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.
Issue: SPR-14614
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 adds a test runtime dependency on log4j 2 for every project
and migrates all log4j.properties files to log4j2-test.xml files.
