"""Tests for Step 3.6: cloud provider integration clients.
Coverage:
Unit \u2014 app/integrations/__init__.py:
- encrypt_token / decrypt_token round-trip
- decrypt_token raises ValueError on invalid ciphertext
- encrypt_token raises ValueError on empty/non-dict input
- _get_fernet raises RuntimeError when OAUTH_ENCRYPTION_KEY not set
- get_provider returns GmailClient for 'gmail'
- get_provider returns MSGraphClient for 'outlook' and 'teams'
- get_provider raises ValueError for unknown provider
Unit \u2014 app/integrations/gmail.py:
- _build_gmail_query with no filter returns empty string
- _build_gmail_query with labels builds label: expr
- _build_gmail_query with senders builds from: expr
- _build_gmail_query with date_range builds after:/before: exprs
- _build_gmail_query since overrides date_range.from when more recent
- _build_gmail_query date_range.from overrides since when more recent
- _parse_body extracts text/plain part
- _parse_body extracts text/html part (stripped)
- _parse_body recurses into multipart, prefers text/plain
- GmailClient.fetch_messages: happy path with mocked service
- GmailClient.fetch_messages: no messages returns empty list
- GmailClient.fetch_messages: HTTP error on messages.list raises RuntimeError
- GmailClient.refreshed_credentials: None when token unchanged
- GmailClient.refreshed_credentials: returns dict when token changes
Unit \u2014 app/integrations/ms_graph.py:
- _build_email_filter with no filter returns empty string
- _build_email_filter with senders builds OData from clause
- _build_email_filter with since builds receivedDateTime ge clause
- MSGraphClient.fetch_emails: happy path with mocked httpx
- MSGraphClient.fetch_emails: 401 triggers token refresh and retries
- MSGraphClient.fetch_messages: happy path with mocked httpx
- MSGraphClient.fetch_messages: 403 from getAllMessages degrades gracefully
- MSGraphClient.refreshed_credentials: None when token unchanged
- MSGraphClient._refresh_access_token: MSAL error raises RuntimeError
