SDTF SNA Test Case Libraries

The SNA Development and Test Facility has two ready to run test suites for SNA protocols: 3270/5250/RJE and LU6.2 APPC/APPN. Both suites can be run with multiple link types and come with test specifications, source coding, and results analysis manuals. The results analysis manuals analyze the results of the tests when run with real IBM products. The tests are not 'trained' to run with the IBM products but were developed from published specifications.

The 3270/5250/RJE tests consist of 137,206 lines of coding, 2,312 test cases, and 568 test programs.

The LU6.2 tests consist of 222,218 lines of coding, 10,658 test cases, and 752 test programs.

The test suites contain both positive and negative verification tests and performance tests. Since the tests are PC based they allow 100% test coverage, which is not possible using mainframe based testing approaches. Users may also write their own tests or modify existing tests, since source code is provided.

These tests may execute using the following data link types:

SDLC - Leased or Dialup
LAN - Token Ring and Ethernet
X-25 Leased

Note: The descriptions below include the names of the major test groups, the number of tests in the group, and the names of the individual libraries in the groups (library_name/description, followed by the major functions of the library).
