 Test cases should normally not be removed from the code base: if something has worked before, it should keep working in future versions, so we should keep testing it.

It can only be enforced through review of library changes. The review may be assisted by a tool that compares the old and the new version, in the same way that `abi-check.py` compares the library's API and ABI.

 If the way certain keys are stored changes, and we don't deliberately decide to stop supporting old keys (which should only be done by retiring a version of the storage format), then we should keep the corresponding test cases in load-only mode: create a file with the expected content, load it and check the data that it contains.

-Purpose
+This script compares the interfaces of two versions of Mbed TLS, looking
+for backward incompatibilities between two different Git revisions within
+an Mbed TLS repository. It must be run from the root of a Git working tree.
 
-This script is a small wrapper around the abi-compliance-checker and
-abi-dumper tools, applying them to compare the ABI and API of the library
-files from two different Git revisions within an Mbed TLS repository.
-The results of the comparison are either formatted as HTML and stored at
-a configurable location, or are given as a brief list of problems.
-Returns 0 on success, 1 on ABI/API non-compliance, and 2 if there is an error
-while running the script. Note: must be run from Mbed TLS root.
+For the source (API) and runtime (ABI) interface compatibility, this script
+is a small wrapper around the abi-compliance-checker and abi-dumper tools,
+applying them to compare the header and library files.
+
+For the storage format, this script compares the automatically generated
+storage tests and the manual read tests, and complains if there is a
+reduction in coverage. A change in test data will be signaled as a
+coverage reduction since the old test data is no longer present. A change in
+how test data is presented will be signaled as well; this would be a false
+positive.
+
+The results of the API/ABI comparison are either formatted as HTML and stored
+at a configurable location, or are given as a brief list of problems.
+Returns 0 on success, 1 on non-compliance, and 2 if there is an error
+while running the script.
+
+You must run this test from an Mbed TLS root.
