In commit 9711db787e, we introduced support for disabling test
application context pausing via a Spring property or JVM system
property, as follows.
-Dspring.test.context.cache.pause=never
However, users may actually be interested in keeping the pausing
feature enabled if contexts are not paused unnecessarily.
To address that, this commit introduces a new
PauseMode.ON_CONTEXT_SWITCH enum constant which is now used by default
in the DefaultContextCache.
With this new pause mode, an unused application context will no longer
be paused immediately. Instead, an unused application context will be
paused lazily the first time a different context is retrieved from or
stored in the ContextCache. This effectively means that an unused
context will not be paused at all if the next test class uses the same
context.
Although ON_CONTEXT_SWITCH is the now the default pause mode, users
still have the option to enable context pausing for all usage scenarios
(not only context switches) by setting the Spring property or JVM
system property to ALWAYS (case insensitive) — for example:
-Dspring.test.context.cache.pause=always
This commit also introduces a dedicated "Context Pausing" section in
the reference manual.

This part of the reference documentation covers topics that apply to multiple modules

within the core Spring Framework.

== Spring Properties
|
|
|
|
{spring-framework-api}/core/SpringProperties.html[`SpringProperties`] is a static holder
|
|
for properties that control certain low-level aspects of the Spring Framework. Users can
|
|
configure these properties via JVM system properties or programmatically via the
|
|
`SpringProperties.setProperty(String key, String value)` method. The latter may be
|
|
necessary if the deployment environment disallows custom JVM system properties. As an
|
|
alternative, these properties may be configured in a `spring.properties` file in the root
|
|
of the classpath -- for example, deployed within the application's JAR file.
|
|
|
|
The following table lists all currently supported Spring properties.
