From ac9a98bc526ecef85c8ada5b27f0ff5506223b57 Mon Sep 17 00:00:00 2001 From: Artur Khantimirov Date: Tue, 18 Aug 2026 13:04:40 +1200 Subject: [PATCH 01/11] Add e2e/check: pure error-returning assertions for e2e tests Implements github.com/Azure/agentbaker/e2e/check with a generic, error-returning assertion API (no testing import, no panics, no ANSI, no failure callbacks): Equal[T]/NotEqual[T], Contains/NotContains (string), ContainsElement/ NotContainsElement ([]E), ContainsKey/NotContainsKey (map[K]V), NoError/Error/ErrorContains, NotNil[T]/NotEmpty[T]/Len[T], True/False/That. Failure is a structured error (Message/Note/Want/Got/Diff/Cause) with deterministic Error() output and Unwrap() for errors.Is/As. Uses reflect.DeepEqual for equality and cmp.Diff(want, got) for diffs, guarded against go-cmp panics on unexported fields. Adds github.com/google/go-cmp v0.7.0 as a direct dependency in e2e/go.mod (previously only transitive). Includes check/checkconsumer, a separate consumer package that guards against a go vet false positive: formatMessage's fallback previously forwarded straight to fmt.Sprint, which caused go vet's printf analyzer to misclassify every check assertion as a print-style wrapper and flag call sites whose message happened to contain a percent verb. That diagnostic only ever surfaces in importing packages, so vetting check alone can't catch a regression - checkconsumer exists specifically to be caught by the package tests.

Runtime helper functions they call are updated to match, and the handful of fallible VMConfigMutator/ BootstrapConfigMutator closures (VM extension creation, Windows 2025 kubelet version lookup, RCV1P branch CSE zip build) now use the error-capable VMConfigMutatorWithError/BootstrapConfigMutatorWithError fields instead of failing via testing.T. - Former require-style (failCheck) chains short-circuit with "if err := ...; err != nil { return err }", preserving execution order. - Former sequential checks that are genuinely independent (unrelated file/service assertions on an already-provisioned node) are combined with errors.Join so a single run surfaces every failure instead of stopping at the first. - s.T.Logf, s.T.Cleanup, and Scenario.T are unchanged; no addCleanup or toolkit.Logf introduced. - Testify is untouched in the three pure unit tests that do not call RunScenario (Test_Version_Consistency_GPU_Managed_Components, Test_extractPackageRevision, Test_CreateVMExtensionLinuxAKSNode_Timing). gofmt, go vet ./..., go build ./..., and go test -run '^$' ./... all pass against the current state of the sibling core/validator/special changes.
