CLI app for developers prototyping atproto functionality
test(oauth-client): add end-to-end snapshot and CLI smoke tests for AC6/AC7/AC8
Creates three new integration test files:
- tests/oauth_client_endtoend.rs: Full pipeline regression tests with snapshots for
the happy path (AC8.1), exit code verification for all scenarios (AC8.1-AC8.4).
Tests verify exit codes: 0 on success, 1 on SpecViolation, 2 on NetworkError only.
Advisory and Skipped checks do not affect exit codes.
- tests/oauth_client_cli.rs: CLI smoke tests using assert_cmd to verify
- help flag output contains 'target' argument (AC8.9)
- interactive subcommand help includes --port and --public-base-url (AC8.9)
- static mode help does NOT include interactive-only flags (AC8.9)
- --verbose flag is accepted (AC8.5)
- --no-color flag is accepted (AC8.6)
- tests/oauth_client_check_id_coverage.rs: Metadata verification that snapshot
files exist and contain expected diagnostic codes (AC8.7, AC8.8).
Includes test infrastructure for running full pipeline with mocked HTTP client,
deterministic fixtures, and snapshot regression baselines.
