 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.
