+=== Test Types
+
+The ACVP server performs a set of tests on the specified SPDM algorithm in order to assess the correctness and robustness of the implementation. A typical ACVP validation session *SHALL* require multiple tests to be performed for every supported permutation of SPDM capabilities. This section describes the design of the tests used to validate implementations of the SPDM algorithms. The number of tests *MAY* vary but the minimum number required by each test type *SHALL* be included by the server. The test type describes the format of the test rather than the intention of the test. Multiple tests of the same test type *MAY* cover different assurances regarding the implementation. 
+
+==== SPDM Test Types
+
+* KDF / SPDM / * "AFT" - Algorithm Functional Test. 
+
+For each test case provided the IUT *SHALL* perform the key schedule. The IUT *SHALL* use the provided key, th1, and th2 values. The IUT-computed requestHandshakeSecret, responseHandshakeSecret, requestDataSecret, responseDataSecret, and exportMasterSecret are communicated to the ACVP server and compared to the requestHandshakeSecret, responseHandshakeSecret, requestDataSecret, responseDataSecret, and exportMasterSecret. This tests the implementation of Section 12 `Key schedule` from <<DSP0274 1.4.0>>. The server *SHALL* provide at least 20 tests for each combination of capabilities.

+== Test Vectors
+
+The ACVP server provides test vectors to the ACVP client, which are then processed and returned to the ACVP server for validation. A typical ACVP validation test session would require multiple test vector sets to be downloaded and processed by the ACVP client. Each test vector set represents an individual cryptographic algorithm defined during the capability exchange. This section describes the JSON schema for a test vector set used with {spec-algorithm} algorithms.
+
+The test vector set JSON schema is a multi-level hierarchy that contains meta data for the entire vector set as well as individual test vectors to be processed by the ACVP client. The following table describes the JSON elements at the top level of the hierarchy.
+
+.Top Level Test Vector JSON Elements
+|===
+| JSON Values | Description | JSON Type
+
+| acvVersion | Protocol version identifier | string
+| vsId | Unique numeric vector set identifier | integer
+| algorithm | Algorithm defined in the capability exchange | string
+| mode | Mode defined in the capability exchange | string
+| revision | Protocol test revision selected | string
+| testGroups | Array of test group JSON objects. Depending on the algorithm, see <<SPDM_keySChedule_tgjs>> | array
