+//! @SYMTestCaseID PBASE-T_RCACHE-0190
+//! @SYMTestType CIT
+//! @SYMPREQ PREQ914
+//! @SYMTestCaseDesc This test case is exercising the Read Caching functionality added to
+//! the File Server. There are negative and positive tests.
+//! @SYMTestActions 0 setup the environment to execute the tests
+//! 1 TestNegative creates situations where the cached content needs to be
+//! flushed or removed from the cache by corrupting files and verifies
+//! the cache behaviour
+//! 2 TestSimpleRead ensures that the cache is working in the simple cases,
+//! with a combination of sync and async reads:
+//! a. The file fits in the cache
+//! b. The file doesn't fit in the cache
+//! 3 TestRepeatedRead verifies the cache behaviour when a file is read an
+//! arbitrary number of times, with and without other operations ongoing
+//! 4 TestReadAhead reads 3 times from a file and verifies that the read
+//! ahead functionality acts afterwards.
+//! 5 TestConcurrent reads files concurrently and verifies how the cache
+//! copes with it.
+//! 6 TestFillCache fills the cache and then executes TestSimpleRead.
+//!
+//! @SYMTestExpectedResults finishes if the read cache behaves as expected, panics otherwise
+//! @SYMTestPriority High
+//! @SYMTestStatus Implemented
