Milestone Achievement: 100% Hooks Coverage 🎉
- Hooks coverage: 87.5% (7/8) → 100% (8/8)
- Total tests: 81 → 105 (+29.6%)
- MCP functionality: 0 → 24 tests
useMcpActions Tests (8 tests):
- Test server reload with loading state management
- Use deferred promise pattern to verify loading state transitions
- Verify intermediate loading=true state during async operation
- Verify error toast (duration: 6s) on reload failure
- Ensure loading returns to false after error
- Test optimistic toggle with rollback on failure
- Immediately update enabled flag before API confirmation
- Verify success toast messages for enable/disable
- Roll back state to original value on API failure
- Show error toast (duration: 6s) when toggle fails
- Test server save with list refresh
- Verify ID rewrite logic: saveServer(newId, {...input, id: oldId}) → {id: newId}
- Verify syncOtherSide option correctly propagated to API
- Refresh server list after successful save
- Propagate errors to caller while showing error toast
- Do not refresh list when save fails
- Test server delete with state management
- Verify deleteServerInConfig called with correct parameters
- Verify list refresh removes deleted server
- Show success toast (duration: 1.5s) on delete
- Keep state unchanged on delete failure
- Propagate error to caller with error toast
useMcpValidation Tests (16 tests):
- Test JSON validation (4 tests)
- Return empty string for blank/whitespace text
- Return "mcp.error.jsonInvalid" for parsing failures
- Reject non-object types (string, array)
- Accept valid object payloads
- Test TOML error formatting (2 tests)
- Map mustBeObject/parseError to "mcp.error.tomlInvalid"
- Append error details for unknown errors
- Test TOML config validation (5 tests)
- Propagate errors from validateToml utility
- Return "mcp.error.commandRequired" for stdio without command
- Return "mcp.wizard.urlRequired" for http without url
- Catch and format tomlToMcpServer exceptions
- Return empty string when validation passes
- Test JSON config validation (5 tests)
- Reject invalid JSON syntax
- Reject mcpServers array format (single object required)
- Require command field for stdio type servers
- Require url field for http type servers
- Accept valid server configurations
Technical Highlights:
- Deferred Promise Pattern: Precise async timing control
- Optimistic Updates: Test immediate feedback + rollback
- Error Propagation: Distinguish caller errors vs toast notifications
- i18n Validation: All validators return translation keys
- Factory Functions: Reusable test data builders
All tests passing: 105/105
