This commit introduces new `isEmpty()` and `isNotEmpty()` methods in
`JsonPathResultMatchers` and `JsonPathRequestMatchers` which delegate
to the new `assertValueIsEmpty()` and `assertValueIsNotEmpty()` methods
in `JsonPathExpectationsHelper`, respectively.
Issue: SPR-13352
Commit fffdd1e9e9 introduced additional
JsonPath result matchers in JsonPathResultMatchers for server-side
testing of MVC controllers.
This commit introduces comparable methods in JsonPathRequestMatchers
for client-side testing with a RestTemplate.
- isString()
- isBoolean()
- isNumber()
- isMap()

Prior to this commit, the exists() method in JsonPathExpectationsHelper
correctly asserted that the evaluated JsonPath expression resulted in a
value (i.e., that a non-null value exists); however, if the value was
an empty array, the exists() method always threw an AssertionError.
The existing behavior makes sense if the JsonPath expression is
'indefinite' -- for example, if the expression uses a filter to select
results based on a predicate for which there is no match in the JSON
document, but the existing behavior is illogical and therefore invalid
if the JsonPath expression is 'definite' (i.e., directly references an
array in the JSON document that exists but happens to be empty). For
example, prior to this commit, the following threw an AssertionError.
new JsonPathExpectationsHelper("$.arr").exists("{ 'arr': [] }");
Similar arguments can be made for the doesNotExist() method.
After thorough analysis of the status quo, it has become apparent that
the existing specialized treatment of arrays is a result of the fact
that the JsonPath library always returns an empty list if the path is
an 'indefinite' path that does not evaluate to a specific result.
Consult the discussion on "What is Returned When?" in the JsonPath
documentation for details:
https://github.com/jayway/JsonPath#what-is-returned-when
This commit addresses these issues by ensuring that empty arrays are
considered existent if the JsonPath expression is definite but
nonexistent if the expression is indefinite.
Issue: SPR-13351
Prior to this commit, a JsonPath assertion that a path expression
evaluated to an array in JsonPathExpectationsHelper (and therefore
indirectly in JsonPathResultMatchers in Spring MVC Test) would
incorrectly fail if the array was present in the JSON content but empty.
This commit fixes this issue by removing the "not empty" check for
arrays and lists.
Issue: SPR-13320
Prior to this commit, MockHttpServletRequestBuilder always supplied an
array of cookies to the MockHttpServletRequest that it built, even if
the array was empty.
However, this violates the contract of HttpServletRequest. According to
the Servlet API, the getCookies() method "returns null if no cookies
were sent."
This commit ensures that MockHttpServletRequestBuilder no longer
configures an empty array of cookies in the mock request that it builds.
Issue: SPR-13314
This commit introduces the following methods in JsonPathResultMatchers
in the Spring MVC Test framework.
- isString()
- isBoolean()
- isNumber()
- isMap()
In addition, this commit overhauls the Javadoc in
JsonPathResultMatchers and JsonPathExpectationsHelper.

SPR-11512 introduced support for annotation attribute aliases via
@AliasFor, requiring the explicit declaration of the 'attribute'
attribute. However, for aliases within an annotation, this explicit
declaration is unnecessary.
This commit improves the readability of alias pairs declared within an
annotation by introducing a 'value' attribute in @AliasFor that is an
alias for the existing 'attribute' attribute. This allows annotations
such as @ContextConfiguration from the spring-test module to declare
aliases as follows.
public @interface ContextConfiguration {
@AliasFor("locations")
String[] value() default {};
@AliasFor("value")
String[] locations() default {};
// ...
}
Issue: SPR-13289
This commit fixes numerous references to 'legacy' packages within the
Javadoc for the Spring MVC Test framework.
In addition, this commit improves examples in Javadoc, adds links to
related classes where appropriate, and removes unnecessary imports for
types that are only referenced within documentation.
Issue: SPR-13284
This commit introduces a dedicated build() method in
MockMvcHtmlUnitDriverBuilder to replace createDriver(). In addition,
the configureDriver() method has been renamed to withDelegate() and now
returns the builder for further customization.
This commit also overhauls the Javadoc for static factory methods and
the class-level Javadoc in MockMvcHtmlUnitDriverBuilder for greater
clarity to end users.

This commit introduces a dedicated build() method in
MockMvcWebClientBuilder to replace createWebClient(). In addition, the
configureWebClient() method has been renamed to withDelegate() and now
returns the builder for further customization.
This commit also overhauls the constructor and class-level Javadoc in
MockMvcWebClientBuilder for greater clarity to end users.

This commit renames the configureWebClient() method in
WebConnectionHtmlUnitDriver to modifyWebClientInternal() in order to
better convey the relationship to HtmlUnitDriver#modifyWebClient().

This commit introduces integration between MockMvc and HtmlUnit, thus
simplifying end-to-end testing when using HTML-based views and enabling
developers to do the following.
- Easily test HTML pages using tools such as HtmlUnit, WebDriver, & Geb
without the need to deploy to a Servlet container
- Test JavaScript within pages
- Optionally test using mock services to speed up testing
- Share logic between in-container, end-to-end tests and
out-of-container integration tests

Since @TransactionConfiguration is now deprecated, this commit also
deprecates TransactionConfigurationAttributes with the intention of
completely removing TransactionConfigurationAttributes once
@TransactionConfiguration has been removed.
Issue: SPR-13277
Due to common usage of @Rollback(false), this commit introduces a new
@Commit annotation that more clearly conveys the intent of the code
while retaining the run-time semantics.
@Commit is in fact meta-annotated with @Rollback(false).
Issue: SPR-13279
Since Spring Framework 2.5, @Rollback has been supported on test
methods, with class-level rollback settings configured via
@TransactionConfiguration; however, allowing @Rollback to be declared
on test classes with method-level declarations overriding class-level
declarations would prove more intuitive than having to declare both
@TransactionConfiguration and @Rollback. Furthermore, the
transactionManager flag in @TransactionConfiguration was made
superfluous many years ago with the introduction of support for a
qualifier in @Transactional.
This commit enables @Rollback to be declared at the class level for
default rollback semantics within test class hierarchies and deprecates
@TransactionConfiguration in favor of @Rollback and @Transactional
qualifiers.
Issue: SPR-13276, SPR-13277
Prior to this change, calling the `setDateHeader` method on a
Spring Test MockHttpServletResponse instance would just store the given
long value in a Map, not writing it as a formatted date String.
Also, calling `getDateHeader` on a MockHttpServletRequest would not
support date strings and could not parse those values.
This can be problematic when testing features related to date headers
such as "Expires", "If-Modified-Since", "Last-Modified", etc.
This commit adds formatting and parsing capabilities to Servlet Mocks
for date strings in HTTP headers.
When formatting dates to Strings, the date format used is the one
preferred by the HTTP RFC. When parsing date Strings, multiple date
formats are supported for better compatibility.
Issue: SPR-11912
SPR-13211 introduced support for reusing mock requests in Spring MVC
Test if the request was created by the the Spring TestContext
Framework. Unfortunately, that change makes it impossible for
MockMvc.perform() to be invoked multiple times within the same test
method without side effects. For example, session attributes and
request parameters are transparently and unexpectedly retained for
subsequent invocations of perform(), causing certain categories of
tests to fail.
This commit reverts the changes introduced in SPR-13211 and introduces
a new MockMvcReuseTests class to serve as regression tests within
Spring's test suite.
Issue: SPR-13260, SPR-13211
HTTP headers such as "Expires", "Last-Modified" all use date
strings like "Tue, 21 Jul 2015 10:00:00 GMT". Prior to this commit,
there was no way to match those header values, besides formatting dates
manually.
This commit introduces a new HeaderResultMatcher to test those date
headers using a long timestamp:
```
this.mockMvc.perform(get("/persons/1").header("If-Modified-Since", now))
.andExpect(status().isNotModified())
.andExpect(header().dateValue("Last-Modified", timestamp));
```
Issue: SPR-13263
Prior to this commit, the Spring MVC Test Framework always created a
new MockHttpServletRequest, disregarding any mock request already
present in Spring Web's RequestContextHolder -- for example, one
created by the ServletTestExecutionListener in the Spring TestContext
Framework (TCF).
This commit modifies MockHttpServletRequestBuilder so that it reuses a
mock request created by the TCF. However,
MockMultipartHttpServletRequestBuilder continues to always create a new
MockMultipartHttpServletRequest since a MockHttpServletRequest created
by the TCF is not directly compatible with a
MockMultipartHttpServletRequest. Furthermore, in order to avoid
unforeseen side effects, MockHttpServletRequestBuilder will always
create a new MockHttpServletRequest if a mock request is present in the
RequestContextHolder but not created by the TCF.
Issue: SPR-13211
When using the Spring TestContext Framework (TCF) to load a
WebApplicationContext and the Spring MVC Test Framework (MockMvc) to
test a controller, two instances of MockHttpServletRequest will be
created. Due to an ordering issue with regard to population of the
RequestAttributes, it is therefore possible that a filter accesses the
mocked request managed by the TCF, while the controller accesses the
mocked request managed by MockMvc, and this leads to test failures if
the controller expects data from the filter to be present in the
request.
This commit fixes this bug by ensuring that the RequestAttributes
backed by the mocked request managed by MockMvc are stored in the
RequestContextHolder before any filters are invoked by MockMvc.
Issue: SPR-13217
SPR-12429 introduced various `BEFORE_*` modes in `@DirtiesContext`. To
support these new modes, `DirtiesContextTestExecutionListener` (DCTEL)
was updated to support both `BEFORE_*` and `AFTER_*` modes. However,
there is a problem with having DCTEL support `BEFORE_*` modes since it
is typically configured to execute after the
`DependencyInjectionTestExecutionListener` (DITEL), and this leads to
several undesired side effects:
- The test's `ApplicationContext` is closed by DCTEL *after*
dependencies have been injected into the test instance.
- Injected dependencies may therefore attempt to interact with an
`ApplicationContext` that is no longer _active_.
- If a test has its `ApplicationContext` injected as a dependency,
interaction with the context will likely fail since the context has
been closed.
- Any `TestExecutionListeners` registered after DCTEL will get a _new_
`ApplicationContext` if they invoke `getApplicationContext()` on the
`TestContext`.
This commit fixes these issues by introducing a new
`DirtiesContextBeforeModesTestExecutionListener` (DCBMTEL) that is
registered by default before DITEL. The previous support for `BEFORE_*`
modes has been moved from DCTEL to DCBMTEL. In addition, an
`AbstractDirtiesContextTestExecutionListener` has been extracted from
DCTEL in order to avoid code duplication.
Issue: SPR-13180
Prior to this commit, the Spring MVC Test framework only provided
support for printing debug information about the MvcResult to STDOUT.
This commit introduces support for logging `MvcResult` details at
`DEBUG` level via the Apache Commons Logging API. In addition, this
commit introduces additional `print(..)` variants for printing debug
information to custom output streams and writers.
Specifically, `MockMvcResultHandlers` has been augmented with the
following new static methods:
- `log()`
- `print(OutputStream)`
- `print(Writer)`
Issue: SPR-13171
Prior to this commit, when rendering cookies via `andDo(print())` in
Spring MVC Test, the output for the `MockHttpServletResponse` would
look something like the following:
Cookies = [javax.servlet.http.Cookie@25084a1e]
The reason is that the Cookie class in javax.servlet-api-3.0.1.jar does
not implement toString(). Consequently, nothing about the cookie's
name, value, etc., is displayed, thereby making the debug output for
cookies next to useless.
This commit improves on this by implementing custom toString() logic
for cookies in debug output in Spring MVC Test. For example, the output
now looks like this (without the newlines):
Cookies = [[Cookie@47faa49c name = 'enigma', value = '42', \\
comment = [null], domain = [null], maxAge = -1, \\
path = [null], secure = false, version = 0, \\
httpOnly = false]]
In addition, this commit fixes a minor bug for FlashMap debug output if
the FlashMap is empty.
