This paper discusses a design and an implementation of a MIB taster, a conf
ormance test tool of Management Information Base (MIB) for TMN. A remote te
st method is used as a practical test configuration. We classify test purpo
ses into three; basic interconnection test, capability test and behaviour t
est. Test items for the capability test are defined according to Managed Ob
ject Conformance Statement (MOCS) and Managed Relationship Conformance Stat
ement (MRCS). Test items for the behaviour test is defined according to GDM
O BEHAVIOUR clause. The MIB tester automatically generates test scenarios f
or capability tests, which are also used as those for the basic interconnec
tion test, and supports the scenario creation of the behaviour test in an u
ser-friendly manner. We evaluate the: implemented MIB tester through its ap
plication to the actual TMN agents.
