@SYMTestCaseID SYSLIB-DBMS-CT-3407
@SYMTestCaseDesc Test for defect DEF103023 - DBMS requires ReadDeviceData and WriteDeviceData capability to read from the db.
The current test application has no capabilities at all.
"C:TestDB.DB" database is a secure shared database with:
- no "READ" polycy (no restrictions apply to the database read operations);
- "WRITE" policy with "WriteUserData" capability defined;
- "SCHEMA" policy with "NetworkServices" capability defined;
- table C has no defined securoty policy, so the database security policy will be used;
The current test application should be able to:
- begin/commit/rollback a "read-only" transaction;
But should fail if:
- begin a transaction and try to modify the database within the transaction;
This test function asserts the test cases described above.
@SYMTestPriority High
