Prior to this commit, the size of the ApplicationContext cache in the
Spring TestContext Framework could grow without bound, leading to
issues with memory and performance in large test suites.
This commit addresses this issue by introducing support for setting the
maximum cache size via a JVM system property or Spring property called
"spring.test.context.cache.maxSize". If no such property is set, a
default value of 32 will be used.
Furthermore, the DefaultContextCache has been refactored to use a
synchronized LRU cache internally instead of a ConcurrentHashMap. The
LRU cache is a simple bounded cache with a "least recently used" (LRU)
eviction policy.

Previously, a package private `@ManagedResource` annotated bean was
registered to the JMX domain even if any attempt to invoke an operation
on it will fail since it has to be public.
This commit validates that any `@ManagedResource` annotated bean is
public and throws an InvalidMetadataException otherwise. Note that the
actual bean type does not have to be public as long as the class
annotated with `@ManagedResource` in the hierarchy is pubic and no extra
operations or attributes are defined on the child.

Prior to this commit, the @ContextConfiguration annotation was required
to be present even if default XML files, Groovy scripts, or
@Configuration classes were detected; however, in such cases the
@ContextConfiguration was typically declared empty and therefore
seemingly unnecessary boilerplate.
This commit permits @ContextConfiguration to be omitted whenever it can
be reasonably deduced. Consequently, integration tests such as the
following are now supported.
@RunWith(SpringRunner.class)
public class MyTest {
@Autowired String myBean;
@Test public void example() { /* ... */ }
@Configuration
static class Config {
@Bean String myBean() {
return "Hello";
}
}
}

Prior to this commit, `ServletWebRequest.checkNotModified` would only
support conditional GET/HEAD requests with "If-Modified-Since" and/or
"If-None-Match" request headers. In those cases, the server would return
"HTTP 304 Not Modified" responses if the resource didn't change.
This commit adds support for conditional update requests, such as
POST/PUT/DELETE requests with "If-Unmodified-Since" request headers.
If the underlying resource has been modified since the specified date,
the server will return a "409 Precondition failed" response status
to prevent concurrent updates.
Even if the modification status of the resource is reversed here
(modified vs. not modified), we're keeping here the same intent for the
return value, which signals if the response requires more processing or
if the handler method can return immediately:
```
if (request.checkNotModified(lastModified)) {
// shortcut exit - no further processing necessary
return null;
}
```

In order to align with the relaxed programming models of TestNG and the
upcoming JUnit 5 (with regard to method visibility), this commit
removes the requirement that @BeforeTransaction and @AfterTransaction
methods must be 'public'.

This commit introduces a SpringRunner extension of
SpringJUnit4ClassRunner that is intended to be used as an 'alias' for
SpringJUnit4ClassRunner, primarily in order to simplify configuration
of JUnit 4 based integration tests.
Developers can use this alias as follows:
@RunWith(SpringRunner.class)
public class MySpringIntegrationTests { ... }

This commit adds weak ETag support in ShallowEtagHeaderFilter.
This improves the behavior of the filter in tow ways:
* weak ETags in request headers such as `W/"0badc0ffee"` will be
compared with a "weak comparison" (matching both weak and strong ETags
of the same value)
* when enabled with the "writeWeakETag" init param, the filter will
write weak Etags in its HTTP responses

This is in line with the current behavior of HttpServlet that would
have been in used with dispatchOptionsRequest on the DispatcherSerlvet
set to false (the default prior to 4.3).

Prior to this change SpEL did not have an syntactic
construct enabling easy access to a FactoryBean. With this
change it is now possible to use &foo in an expression when
the factory bean should be returned.

Spring MVC Test now parses application/x-www-form-urlencoded request
content and populates request parameters from it.
This can be useful when running client-side tests against a MockMvc
via MockMvcClientHttpRequestFactory.

Previously, if a database needs to be initialized with several scripts
and many (or all) use a custom separator, said separator must be repeated
for each script.
This commit introduces a `separator` property at the parent element level
that can be used to customize the default separator. This is available
for both the `initialize-database` and `embedded-database` elements.
