Explanation
All changed code is test code in
cmd/configure_gcp_test.goand targetsaddMemberToPolicyBinding. The conditional-binding tests support policy-preservation and access-error behavior of the same helper. No SDK round-trip mocking or unrelated production change was added.

Explanation
Issue
#1284requires a table-driven test incmd/configure_gcp_test.gothat covers cases 1-5. The PR adds separate test functions instead. The tests cover the required behaviors, including empty policy, existing members, missing roles, duplicate roles, and conditional bindings, but they do not meet the required table-driven test structure.Resolution
Add or refactor the
addMemberToPolicyBindingcoverage into a table-driven test that includes issue#1284cases 1-5 and asserts the expectedchanged, error, and complete policy state.

Assert the full binding list when creating a missing binding, use an exact error message, and cover a conditional binding followed by an unconditional one for the same member (no-op, no error). Refs #1284 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

199-199: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winAssert the conditional-access error without fixing its full wording.
require.EqualErrormakes this test fail if the explanatory text changes but the error behavior stays the same. Check the distinguishing conditional-access text, member, and role instead. Based on learnings, “prefer checking the error type/class (and only essential distinguishing fields) rather than matching exact error message text, unless the message is a documented part of the API contract.”🤖 Prompt for AI Agents

201-204: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winUse an independent condition in the unchanged-policy assertion.
The expected binding reuses
cond, which is also inpolicy.Bindings. If the helper mutates a condition field, both sides of this assertion see the new value. Copy the condition before the call and use that copy in the expected binding.🤖 Prompt for AI Agents

Closes #1284
Test-only change in
cmd/configure_gcp_test.go; no behavior change. Items 1-3 of the issue were already covered. Each new test asserts the exact resulting policy.EmptyPolicyCreatesBinding: empty policy gets a single binding with exactly the requested member.MultipleBindingsSameRole: with two unconditional bindings of one role, the member goes to the last one and other bindings are untouched; a member already in the first binding is a no-op.OnlyConditionalAccessErrors: a member bound only via a conditional binding returns the "has only conditional access" error,changed=false, policy unchanged.UnconditionalAmongConditional: member is appended to the unconditional binding between conditional ones; a role with only conditional bindings gets a new unconditional binding.Verification (run under the heavy lock):
go vet ./...,go test -timeout 300s -count=1 ./cmd/..., golangci-lint, andscripts/test-git-secrets-allowlist.shall pass.🤖 Generated with Claude Code
