====
Since Spring Framework 4.3, the size of the context cache is bounded with a default
maximum size of 32. Whenever the maximum size is reached, a _least recently used_ (LRU)
eviction policy is used to evict and close stale contexts. The maximum size can be
configured from the command line or a build script by setting a JVM system property named
`spring.test.context.cache.maxSize`. As an alternative, the same property can be set
programmatically via the `SpringProperties` API.
Since having a large number of application contexts loaded within a given test suite can
cause the suite to take an unnecessarily long time to execute, it is often beneficial to
know exactly how many contexts have been loaded and cached. To view the statistics for
