In browser mode, is there any way to configure the default timeout for expect.element?

[ezzatron]

I usually end up configuring longer timeouts when running under CI. Something like:

// vitest.config.ts
import { defineConfig } from "vitest/config";

const isCI = process.env.CI === "true";

export default defineConfig({
  test: {
    testTimeout: isCI ? 10000 : 1000,
    hookTimeout: isCI ? 30000 : 3000,
  },
});

It would be great to see a similar option to set the default timeout for expect.element, because in my experience the locators do time out frequently under CI, and working around that is non-trivial. Perhaps like:

// vitest.config.ts
import { defineConfig } from "vitest/config";

const isCI = process.env.CI === "true";

export default defineConfig({
  test: {
    testTimeout: isCI ? 30000 : 3000,
    hookTimeout: isCI ? 30000 : 3000,
    browser: {
      locateTimeout: isCI ? 30000 : 3000,
    },
  },
});

For reference, my current workaround is to add a custom command to expose the CI state, and use it to define custom poll options for each expect.element call:

// vitest.config.ts
import { defineConfig } from "vitest/config";

const isCI = process.env.CI === "true";

export default defineConfig({
  test: {
    testTimeout: isCI ? 10000 : 1000,
    hookTimeout: isCI ? 30000 : 3000,
    browser: {
      commands: {
        isCI: () => isCI,
      },
    },
  },
});

// example.test.ts
import { commands, page } from "@vitest/browser/context";
import { beforeAll, expect, it, type ExpectPollOptions } from "vitest";
import { render } from "vitest-browser-react";
import Component from "./Component";

let pollOptions: ExpectPollOptions;

beforeAll(async () => {
  pollOptions = { timeout: (await commands.isCI()) ? 10000 : 1000 };
});

it("uses a different poll timeout for CI", async () => {
  render(<Component />);

  await expect.element(page.getByText(/example/i, pollOptions)).toBeVisible();
});

expect.element internally uses expect.poll, so timeout config should be this one https://vitest.dev/guide/cli-generated.html#expect-poll-timeout If documentation is missing this connection, any suggestion is welcome.

Thank you! Somehow missed that one when searching 🤦
