| description | Add a test case to the web renderer |
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
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'});
});

Publish Remotion Lambda Chrome binaries to the eu-central-1 test region and update hosted layer and Chrome version references. Use when updating Chrome binaries before full regional rollout.
Document Remotion skill placement. Use when adding, moving, or editing Remotion skills to decide whether a skill belongs in .agents/skills as an internal skill or packages/skills as a public skill.
Guidance for Remotion Studio UI changes where the global CSS reset affects nested elements. Use when editing packages/studio UI, especially when adding wrapper spans, inline icons, labels, buttons, compact rows, or any nested text whose typography, color, sizing, or truncation must stay stable.
Start Remotion Studio from packages/example and open it in the Codex browser. Use when the user invokes /studio or $studio, asks to launch the example Studio, or wants the Remotion Studio dev UI available locally.
