Summary

Summary by CodeRabbit

Tests
- Expanded coverage for gRPC authorization policies, including anonymous and deny-all access, identity and role checks, and combined authorizers.
- Added checks for per-RPC policy selection, interceptor decisions, context and method forwarding, and authorization error handling.
- Verified allowed and denied outcomes, missing credentials, authorizer evaluation behavior, and policy configuration edge cases across varied contexts and service types.

Tests were added across gRPC authorization packages. They cover authorizer outcomes, identity and role checks, per-RPC selection, error handling, and interceptor behavior.

Changes: gRPC authorization tests

Layer / File(s)	Summary
Authorizer outcomes and composition `pkg/grpc/authz/allow/allow_test.go`, `pkg/grpc/authz/deny/deny_test.go`, `pkg/grpc/authz/and/and_test.go`, `pkg/grpc/authz/or/or_test.go`	Tests cover basic authorization outcomes, configured-denial errors, composition behavior, argument forwarding, and sensor and scanner identity cases.
Identity and role authorization `pkg/grpc/authz/idcheck/idcheck_test.go`, `pkg/grpc/authz/user/role_test.go`	Tests cover identity presence, service-type matching, role matching, and related authorization errors.
Per-RPC authorization routing `pkg/grpc/authz/perrpc/per_rpc_test.go`	Tests cover mapped and default authorizers, RPC-name forwarding, `FromMap` behavior, and duplicate RPC names.
Authorization interceptor behavior `pkg/grpc/authz/interceptor/interceptor_test.go`	Tests cover authorization status formatting, context updates, and checker decisions about errors and handler invocation.

Full details: Description check

Explanation

The description includes the required sections, explains the test-focused change, and records validation. The CI inspection checkbox and added unit tests checkbox remain unchecked, but the description is otherwise sufficiently complete.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 17 functions across 8 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Assert the forwarded context and method name in TestOr_ForwardsContextAndMethod.

The test asserts only the call count. recordingAuthorizer ignores both the context and the method name. The test still passes if Or forwards a different context or method name. Record both arguments and assert that they match the inputs.

Suggested fix

-// recordingAuthorizer captures every Authorized call for inspection.
-type recordingAuthorizer struct {
-	calls int
-	err   error
-}
-
-func (r *recordingAuthorizer) Authorized(_ context.Context, _ string) error {
-	r.calls++
-	return r.err
-}
+// recordingAuthorizer captures every Authorized call for inspection.
+type recordingAuthorizer struct {
+	calls  int
+	err    error
+	ctx    context.Context
+	method string
+}
+
+func (r *recordingAuthorizer) Authorized(ctx context.Context, method string) error {
+	r.calls++
+	r.ctx = ctx
+	r.method = method
+	return r.err
+}

 	rec := &recordingAuthorizer{}
 	Or(rec).Authorized(ctx, method)
 	assert.Equal(t, 1, rec.calls)
+	assert.Equal(t, ctx, rec.ctx)
+	assert.Equal(t, method, rec.method)

stores the context and method passed to Authorized, then assert both match the
