# E2E Test Utilities
Shared infrastructure for running `@composio/core` and CLI end-to-end tests in isolated Docker environments.
## What's Here
| File/Directory | Purpose |
| ----------------- | ---------------------------------------------------- |
| `src/` | TypeScript utilities (e2e runner, config, types) |
| `scripts/` | Docker build and cleanup scripts |
| `Dockerfile.node` | Multi-stage Dockerfile for Node.js test environments |
| `Dockerfile.deno` | Dockerfile for Deno test environments |
| `Dockerfile.cli` | Scratch Dockerfile for CLI test environments |
## API
### `e2e`
The main entry point for e2e tests. Automatically infers the working directory and suite name from the caller's location. Uses `bun:test` for the test framework.
```typescript
import { e2e, type E2ETestResult } from '@e2e-tests/utils';
import { TIMEOUTS } from '@e2e-tests/utils/const';
import { describe, it, expect, beforeAll } from 'bun:test';
e2e(import.meta.url, {
versions: {
node: ['22.22.3', '24.17.0', '25.9.0'], // optional, defaults to mise.toml
deno: ['2.6.7'], // optional, defaults to mise.toml
cli: ['current'], // optional, defaults to CLI package.json version
},
env: { MY_VAR: 'value' }, // optional env vars
defineTests: ({ runtime, runCmd, runFixture }) => {
let result: E2ETestResult;
beforeAll(async () => {
result = await runFixture({ filename: 'fixtures/test.mjs' });
}, TIMEOUTS.FIXTURE);
describe('output', () => {
it('exits successfully', () => {
expect(result.exitCode).toBe(0);
});
});
},
});
```
### `E2EConfig`
Configuration object passed to `e2e()`:
| Property | Type | Description |
| -------------- | ------------------------------------- | ------------------------------------------------------------- |
| `versions` | `RuntimeVersions` | Runtime versions to test. See RuntimeVersions below |
| `env` | `Record<string, string \| undefined>` | Environment variables for Docker. Validated at startup |
| `usesFixtures` | `boolean` | When true, sets cwd to `{testDir}/fixtures`. Default: `false` |
| `defineTests` | `(ctx: DefineTestsContext) => void` | Callback to define tests using bun:test primitives |
### `RuntimeVersions`
| Property | Type | Description |
| -------- | -------------------------------- | ------------------------------------------ |
| `node` | `readonly NodeVersionFromUser[]` | Node.js versions. Defaults to `mise.toml` |
| `deno` | `readonly DenoVersionFromUser[]` | Deno versions. Defaults to `mise.toml` |
| `cli` | `readonly CliVersionFromUser[]` | CLI versions. Defaults to CLI package.json |
### `DefineTestsContext`
The context passed to the `defineTests` callback:
| Property | Type/Signature | Description |
| ------------ | ---------------------------------------------------------------------------------- | ----------------------------------------- |
| `runtime` | `'node' \| 'deno' \| 'cli'` | Current runtime being tested |
| `runCmd` | `(command: string) => Promise<E2ETestResult>` | Run arbitrary command in Docker container |
| `runFixture` | `(options: RunFixtureOptions) => Promise<E2ETestResult \| E2ETestResultWithSetup>` | Run fixture with optional setup phase |
### `RunFixtureOptions`
Options for `runFixture()`:
| Property | Type | Description |
| ---------- | -------- | ------------------------------------------------------------------- |
| `filename` | `string` | Fixture file path relative to cwd (e.g., `'index.mjs'`) |
| `setup` | `string` | Optional setup command (e.g., `'npm install'`). Enables volume mode |
**Behavior:**
- **Without `setup`**: Runs `node <filename>` directly. Returns `E2ETestResult`.
- **With `setup`**: Creates a Docker volume, runs setup with volume mounted read-write, then runs fixture with volume mounted read-only. Returns `E2ETestResultWithSetup`.
```typescript
// Simple fixture (no dependencies to install)
const result = await runFixture({ filename: 'test.mjs' });
// Fixture with setup phase (uses Docker volumes)
const result = await runFixture({
filename: 'index.mjs',
setup: 'npm install --legacy-peer-deps',
});
expect(result.setup.exitCode).toBe(0); // Check setup phase
expect(result.exitCode).toBe(0); // Check fixture phase
```
### `E2ETestResult`
Result returned by `runCmd` and `runFixture`:
```typescript
interface E2ETestResult {
exitCode: number; // Exit code from the command (0 = success)
stdout: string; // Captured stdout
stderr: string; // Captured stderr
}
```
### `runCmd` with File Capture
When you need to assert on files created inside the container, pass a `files` array:
```typescript
const result = await runCmd({
command: 'composio version > out.txt',
files: ['out.txt'],
});
expect(result.files['out.txt']).toBe('0.1.24');
```
The files are copied out of the container after execution and returned as a map in the result.
### `E2ETestResultWithSetup`
Extended result when `runFixture` is called with a `setup` option:
```typescript
interface E2ETestResultWithSetup extends E2ETestResult {
setup: {
exitCode: number;
stdout: string;
stderr: string;
};
}
```
Top-level fields (`exitCode`, `stdout`, `stderr`) reflect the fixture result. The `setup` object contains the setup command result.
### `sanitizeOutput`
Utility for stable test comparisons. Removes ANSI escape codes, normalizes line endings, and trims whitespace.
```typescript
import { sanitizeOutput } from '@e2e-tests/utils';
const clean = sanitizeOutput(result.stdout);
```
### `TIMEOUTS`
Predefined timeout constants for tests (in milliseconds):
```typescript
import { TIMEOUTS } from '@e2e-tests/utils/const';
it(
'calls LLM',
async () => {
// test code
},
{ timeout: TIMEOUTS.LLM_SHORT }
);
```
| Constant | Value | Use Case |
| ----------- | --------- | ------------------------------------------ |
| `DEFAULT` | `5_000` | Standard test operations |
| `FIXTURE` | `120_000` | `beforeAll` hooks that call `runFixture()` |
| `LLM_SHORT` | `30_000` | Quick LLM calls |
| `LLM_LONG` | `60_000` | Complex LLM operations |
## Version Resolution
### Node.js Version Resolution
Node.js versions to test are resolved in this order:
1. **`COMPOSIO_E2E_NODE_VERSION` env var** (highest priority): Use `[env_value]`
2. **`config.versions.node`**: Use the provided array
3. **Default**: Use version from `mise.toml` file
### Well-Known Node Versions
The following versions are pre-defined in `const.ts`:
- `22.22.3`
- `24.17.0`
- `25.9.0`
- `current` (resolves to `mise.toml` version)
### Deno Version Resolution
Deno versions to test are resolved in this order:
1. **`COMPOSIO_E2E_DENO_VERSION` env var** (highest priority): Use `[env_value]`
2. **`config.versions.deno`**: Use the provided array
3. **Default**: Use version from `mise.toml` file
### Well-Known Deno Versions
The following versions are pre-defined in `const.ts`:
- `2.6.7`
- `current` (resolves to `mise.toml` version)
### CLI Version Resolution
CLI versions to test are resolved in this order:
1. **`COMPOSIO_E2E_CLI_VERSION` env var** (highest priority): Use `[env_value]`
2. **`config.versions.cli`**: Use the provided array
3. **Default**: Use version from `ts/packages/cli/package.json`
### Well-Known CLI Versions
- `current` (resolves to CLI package.json version)
## Environment Variable Validation
Environment variables passed to `E2EConfig.env` are validated at test startup. If any variable has an `undefined` value, the test fails fast with a clear error message:
```
[my-test] Missing required environment variables: COMPOSIO_API_KEY, OPENAI_API_KEY
Set these variables before running the tests, or remove them from E2EConfig.env if not required.
```
This prevents silent failures from missing credentials.
## The `usesFixtures` Option
When `usesFixtures: true` is set:
- Working directory changes to `{testDir}/fixtures/`
- Docker volume mounts at `fixtures/node_modules`
- Fixture paths in `runFixture({ filename })` are relative to `fixtures/`
Use this for tests that have their own `package.json` and need to run `npm install`:
```typescript
import { TIMEOUTS } from '@e2e-tests/utils/const';
e2e(import.meta.url, {
usesFixtures: true,
defineTests: ({ runFixture }) => {
beforeAll(async () => {
// Both commands run in fixtures/ directory
result = await runFixture({
filename: 'index.mjs', // Resolves to fixtures/index.mjs
setup: 'npm install', // Runs in fixtures/
});
}, TIMEOUTS.FIXTURE);
},
});
```
## Scripts
```bash
# Pre-build Docker images for all well-known Node, Deno, and CLI versions
pnpm docker:build
# Remove all e2e Docker images (Node.js, Deno, and CLI)
pnpm docker:clean
```
## DEBUG.log Output
Each test suite generates a `DEBUG.log` file with structured output grouped by runtime version:

**Features:**
- File cleared at start of each test run (no stale data)
- Phases grouped by Node version for easy scanning
- Visual hierarchy: `===` for file boundaries, `###` for versions, `---` for phases
- Empty stdout/stderr shown as `(empty)`
- Summary with pass/fail/skip status and timing
## Behavior
- Builds an isolated Docker container and runs the test command inside it
- Docker is required
- Tests run sequentially per Node version
- Volume cleanup is best-effort (doesn't fail tests on cleanup errors)
