test(handlers): sqlmock coverage for tokens.go (closes #1819)
The existing tokens_test.go skips every test when db.DB is nil, so CI ran with 0% coverage on tokens.go's List/Create/Revoke. This file adds sqlmock-driven tests that exercise the SQL paths directly without needing a live Postgres, lifting coverage on all 4 functions to 100% and module-level handler coverage from 60.3% → 61.1%.

// Sqlmock-backed coverage for tokens.go. Closes #1819.
|
||||
//
|
||||
// The existing tokens_test.go uses the real `db.DB` and t.Skip's when
|
||||
// the test DB isn't reachable — which is the default in CI, so the
|
||||
// file shows 0% coverage. This file substitutes the package-level
|
||||
// `db.DB` with a sqlmock instance so every code path (List, Create,
|
||||
// Revoke + their error branches) is exercised in `go test` without
|
||||
// any external dependency.
|
||||
//
|
||||
// What's covered:
|
||||
// List — happy path, empty rows, scan failure, query error
|
||||
// Create — rate-limited, IssueToken DB error, happy path
|
||||
// Revoke — happy path, not found, DB error
|
||||
//
|
||||
// What's NOT covered here (intentional):
|
||||
// - Wsauth/middleware-level cross-tenant gating: those are exercised
|
||||
// by middleware/wsauth_middleware_test.go. The handler-level code
|
||||
// trusts WorkspaceAuth has already gated the request.
|
||||
// - The full IssueToken path's correctness (random bytes,
|
||||
// base64 encoding, prefix derivation): wsauth/tokens_test.go owns
|
||||
// that. Here we only verify the handler hands off + reports
|
||||
// errors correctly.
