209-247: Consider adding a negative assertion for operating-regions test.This test verifies that
operatingRegionsincludes all unique regions fromspec.operatingRegions,spec.region, and poollocale. However, it lacksobservedResources, which is fine for testing rendering logic. Consider also verifying no duplicate regions appear (e.g., ifus-east-1were added to bothoperatingRegionsand as the mainregion).
500-553: Gating test is important but could be more explicit.The test verifies that child pool doesn't render when parent isn't ready, but the assertion only checks that the parent pool exists. Consider adding a negative assertion mechanism if the test framework supports it, to explicitly verify the child pool (
test-child-wait-child) is absent.
1131-1197: Verify netmaskLength test doesn't assert cidr absence.The test verifies
VPCIpamPoolCidrusesnetmaskLength = 16, but doesn't explicitly check thatcidris absent. If the composition could erroneously set both fields, this test wouldn't catch it. Consider verifying the expected behavior more explicitly if the framework supports it.

4-12: Well-documented test philosophy.The philosophy comments clearly explain the testing approach: focusing on API behavior rather than provider implementation details. This is an excellent practice for composition tests.
21-80: Basic defaults test looks correct.The test properly validates that minimal spec input produces expected defaults:
managementPolicies = ["*"],providerConfigRef = {name = "default", kind = "ProviderConfig"}, andtags = {hops = "true"}.
812-873: Good test for management policies inheritance.The test correctly verifies that global
managementPolicies = ["Observe"]cascades to bothVPCIpamPoolandVPCIpamPoolCidrresources.
998-1030: Pool gating test validates critical sequencing.This test ensures pools don't render until the IPAM is ready and provides
privateDefaultScopeId. The emptyobservedResources = []and assertion of onlyVPCIpamcorrectly validates this gating behavior.
14-1237: Comprehensive and well-organized test suite.The test suite covers a wide range of scenarios including:
- Default values and inheritance
- Provider config variations
- Tag merging
- Operating regions auto-computation
- Pool constraints and locales
- IPv6 ULA and GUA pools
- Parent/child pool relationships and gating
- External name adoption for IPAM, pools, CIDRs, and scopes
- Custom scopes and scope references
- Management policy inheritance and overrides
- Label propagation
- forProvider passthrough fields
The consistent structure with "When/Then" comments makes tests easy to understand. Based on learnings, ensure corresponding examples exist under
examples/ipams/for any new schema knobs being tested.
