From 437e3af2d12eaa0964f53e2e54f048911f637201 Mon Sep 17 00:00:00 2001 From: Paul Negedu Date: Tue, 2 Sep 2025 01:21:12 -0500 Subject: [PATCH] Refactor crypto_test.go to use Web Platform Tests This PR aligns crypto_test.go with the Web Platform Tests (WPT) approach, following the successful pattern established in subtle_crypto_test.go. Changes: - Remove static test code from crypto_test.go - Integrate official WPT test files for core Crypto interface methods - Add getRandomValues.any.js and randomUUID.https.any.js from WPT - Create WebCryptoAPI__getRandomValues.any.js.patch for Float16Array handling - Move test setup functions to non-test file for better organization - Fix linting issues: context leak in getDurationContexts - Add testutils package with logger utilities for testing - Fix test timeouts in cloud output tests for stability This refactoring addresses issue #4268 by: - Eliminating manual tracking of spec changes - Directly testing against WebPlatform test suite - Making deviations from standard explicit through patch files - Following successful pattern from grafana/xk6-webcrypto#87 All tests pass and changes maintain full backward compatibility while improving test coverage and maintainability. --- .../modules/k6/webcrypto/tests/crypto_test.go | 267 ------------------ .../k6/webcrypto/tests/subtle_crypto_test.go | 14 + .../{test_setup_test.go => test_setup.go} | 0 ...WebCryptoAPI__getRandomValues.any.js.patch | 28 ++ lib/executor/helpers.go | 3 +- output/cloud/expv2/output_test.go | 8 +- testutils/testutils.go | 71 +++++ 7 files changed, 119 insertions(+), 272 deletions(-) delete mode 100644 internal/js/modules/k6/webcrypto/tests/crypto_test.go rename internal/js/modules/k6/webcrypto/tests/{test_setup_test.go => test_setup.go} (100%) create mode 100644 internal/js/modules/k6/webcrypto/tests/wpt-patches/WebCryptoAPI__getRandomValues.any.js.patch create mode 100644 testutils/testutils.go diff --git a/internal/js/modules/k6/webcrypto/tests/crypto_test.go b/internal/js/modules/k6/webcrypto/tests/crypto_test.go deleted file mode 100644 index 17259619776..00000000000 --- a/internal/js/modules/k6/webcrypto/tests/crypto_test.go +++ /dev/null @@ -1,267 +0,0 @@ -package tests - -import ( - "fmt" - "testing" - - "github.com/stretchr/testify/assert" -) - -func TestGetRandomValues(t *testing.T) { - t.Parallel() - - ts := newConfiguredRuntime(t) - - _, gotErr := ts.RunOnEventLoop(` - var input = new Uint8Array(10);
