From e1b8213a727d00eed62470dab4523c0016d36d63 Mon Sep 17 00:00:00 2001 From: Alisue Date: Sat, 21 Mar 2026 19:33:35 +0900 Subject: [PATCH 1/3] fix(test): handle nullable Worker.onmessage in type constraints and call sites Worker.onmessage is typed as `((ev: MessageEvent) => any) | null`, so the existing MethodKeyOf utility (which only maps non-nullable functions) caused type errors when used with Worker. Introduce NullableMethodKeyOf that also matches `T[K] extends AnyFn | null` and apply it to the unimplemented-method list in mock_test.ts. Add non-null assertions at the three call sites in cli_test.ts where onmessage is invoked directly, since the fake worker always provides a value there. --- denops/@denops-private/cli_test.ts | 6 +++--- tests/denops/testutil/mock_test.ts | 6 +++++- 2 files changed, 8 insertions(+), 4 deletions(-) diff --git a/denops/@denops-private/cli_test.ts b/denops/@denops-private/cli_test.ts index 13594e2d..a88b9290 100644 --- a/denops/@denops-private/cli_test.ts +++ b/denops/@denops-private/cli_test.ts @@ -288,7 +288,7 @@ Deno.test("main()", async (t) => { ); await t.step("and the worker stream is closed", async (t) => { - fakeWorker.onmessage(new MessageEvent("message", { data: null })); + fakeWorker.onmessage!(new MessageEvent("message", { data: null })); await delay(0); await t.step("calls Worker.terminate()", () => { @@ -453,7 +453,7 @@ Deno.test("main()", async (t) => { assertSpyCalls(globalThis_Worker, 1); fakeTcpListener.close(); - fakeWorker.onmessage(new MessageEvent("message", { data: null })); + fakeWorker.onmessage!(new MessageEvent("message", { data: null })); await delay(0); await t.step("calls Worker.terminate()", () => { @@ -557,7 +557,7 @@ Deno.test("main()", async (t) => { await delay(0); await t.step("and the worker stream is closed", async (t) => { - fakeWorker.onmessage(new MessageEvent("message", { data: null })); + fakeWorker.onmessage!(new MessageEvent("message", { data: null })); await delay(0); await t.step("outputs error logs", () => { diff --git a/tests/denops/testutil/mock_test.ts b/tests/denops/testutil/mock_test.ts index 6a9af175..b5f5bb33 100644 --- a/tests/denops/testutil/mock_test.ts +++ b/tests/denops/testutil/mock_test.ts @@ -24,6 +24,10 @@ type MethodKeyOf = ({ [K in keyof T]: T[K] extends AnyFn ?
