We need to translate the given text from English to Bahasa Indonesia. The text is about visual snapshot testing for web renderer components using vitest fixtures. We must preserve product names, protocol names, URLs, numbers, and technical terms. The name "web-renderer-test" is not in the text, so we don't include it. We translate only the text inside <text>. No extra commentary. Let's translate: "Visual snapshot testing for web renderer components using vitest fixtures." -> "Pengujian snapshot visual untuk komponen web renderer menggunakan fixture vitest." "Create test fixtures in packages/web-renderer/src/test/fixtures that define a React component, dimensions, frame rate, and duration" -> "Buat fixture pengujian di packages/web-renderer/src/test/fixtures yang mendefinisikan komponen React, dimensi, frame rate, dan durasi" "Register fixtures in packages/web-renderer/src/test/Root.tsx to enable preview functionality" -> "Daftarkan fixture di packages/web-renderer/src/test/R

The web renderer is in packages/web-renderer and the test suite is in packages/web-renderer/src/test.

It uses visual snapshot testing using vitest. A test file can for example be executed using:

bunx vitest src/test/video.test.tsx

Example

Each test is powered by a fixture in packages/web-renderer/src/test/fixtures. A fixture looks like this for example:

import {AbsoluteFill} from 'remotion';

const Component: React.FC = () => {
  return (
    <AbsoluteFill
      style={{
        justifyContent: 'center',
        alignItems: 'center',
      }}
    >
      <div
        style={{
          backgroundColor: 'red',
          width: 100,
          height: 100,
          borderRadius: 20,
        }}
      />
    </AbsoluteFill>
  );
};

export const backgroundColor = {
  component: Component,
  id: 'background-color',
  width: 200,
  height: 200,
  fps: 25,
  durationInFrames: 1,
} as const;

The corresponding test looks like this:

import {test} from 'vitest';
import {renderStillOnWeb} from '../render-still-on-web';
import {backgroundColor} from './fixtures/background-color';
import {testImage} from './utils';

test('should render background-color', async () => {
  const blob = await renderStillOnWeb({
    licenseKey: 'free-license',
    composition: backgroundColor,
    frame: 0,
    inputProps: {},
    imageFormat: 'png',
  });

  await testImage({blob, testId: 'background-color'});
});

Adding a new test

Add a new fixture in packages/web-renderer/src/test/fixtures.
Important: Add the fixture to packages/web-renderer/src/test/Root.tsx to add a way to preview it.
Add a new test in packages/web-renderer/src/test.
Run bunx vitest src/test/video.test.tsx to execute the test.
Important: Update packages/docs/docs/client-side-rendering/limitations.mdx to reflect the newly supported property.
