SCA 2.2.2 Test Suite

The Joint Tactical Networking Center (JTNC) transferred the Software Communications Architecture (SCA) v2.2.2 test procedures and JTNC Test Application (JTAP) to the Wireless Innovation Forum to share with the SCA development community.

The JTNC utilized the SCA v2.2.2 test procedures and the JTAP as part of the product evaluation procedure. Note that although the JTNC does not provide an SCA v2.2.2 Conformance Certification process, the SCA test procedures and JTAP may be utilized to assess product conformance with the SCA requirements. The results gathered through execution of the test procedures should serve as evidence of product conformance, but in order to guarantee the product meets all of the identified acceptance criteria, product developers will need to work with the product procurer or a designated certification authority. The JTNC does not provide a guarantee of accuracy nor ongoing support of the SCA test procedures or JTAP. Please contact WInnF for assistance with any issues.

The SCA v2.2.2 automated test procedures utilize the R Check SCA tool for Application Environment Profile (AEP) validation; however, the R Check SCA tool is no longer commercially available and is not included with this distribution due to contractual restrictions.

The SCA v2.2.2 manual test procedures are available for applications, operating environments, and radio services and cover all of the SCA requirements in lieu of JTAP.
