## Pull Request Summary: Test Case Updates for API Behavior Changes
**Core Invariant**: These test case updates reflect backend API
improvements to error messaging and schema information returned by
collection operations. The changes maintain backward compatibility—no
public signatures change, and all modifications are test expectation
updates.
**Updated Error Messages for Better Diagnostics**:
- `test_add_field_feature.py`: Updated expected error when adding a
vector field without dimension specification from a generic "not support
to add vector field" to the more descriptive "vector field must have
dimension specified, field name = {field_name}: invalid parameter". This
change is non-breaking for clients that only check error codes; it
improves developer experience with clearer error context.
**Schema Information Extension**:
- `test_milvus_client_collection.py`: Added `enable_namespace: False` to
the expected `describe_collection()` output. This is a new boolean field
in the collection metadata that defaults to False, representing an
opt-in feature. Existing code querying describe_collection continues to
work; the new field is simply an additional property in the response
dictionary.
**Dynamic Error Message Construction**:
- `test_milvus_client_search_invalid.py`: Replaced hardcoded error
message with conditional logic that generates the appropriate error
based on input state (None vectors vs invalid vector data). This
prevents test brittle failure if multiple error conditions exist, and
correctly validates the API's behavior handles both "missing data" and
"malformed data" cases distinctly.
**No Regression Risk**: All changes update test expectations to match
improved backend behavior. The changes are additive (new field in
schema) or clarifying (better error messages), with no modifications to
existing response structures or behavior for valid inputs.
