a_test

library1.0.9jsnpmunverified

Compact test framework using when-style assertions with recursive test runner. Current stable version 1.0.9. Sub-package of the 'a' monorepo, focusing on minimalist TDD/BDD syntax. Differentiators: lightweight, recursive test discovery, when-style chaining for readable tests. Cadence: part of 'a' ecosystem, releases tied to main package.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

describe

✓ import { describe } from 'a_test'

✗ const describe = require('a_test')

ESM-only package, no CommonJS export.

✓ import { it } from 'a_test'

✗ import { test } from 'a_test'

Symbol is 'it', not 'test'.

when

✓ import { when } from 'a_test'

when is the primary assertion style.

Minimal test suite using when-style assertions and recursive test runner.

import { describe, it, when } from 'a_test'; describe('Math', () => { it('adds numbers', () => { when(1 + 1).then(2); }); }); test.run();

Debug

Known issues

breakingv1.0.0 switched from 'expect' to 'when' assertion syntax; existing tests using 'expect' will fail.

fix

Replace expect() calls with when().then() pattern.

affects: <1.0.0

deprecateddescribe.skip and it.skip are deprecated; use .skip property on the test callback instead.

fix

Use describe.skip(() => {}) or it.skip(() => {}).

affects: >=1.0.5

gotchaRecursive test runner may cause infinite loops if tests are in parent directories without proper configuration.

fix

Set rootDir option in test.run({ rootDir: './tests' }) to limit scope.

affects: >=1.0.0

Errors

Common errors & fixes

Error: Cannot find module 'a_test'

Package not installed or not in node_modules.

fix

TypeError: (0 , a_test.describe) is not a function

Using CommonJS require instead of ESM import.

fix

Change to 'import { describe } from 'a_test'' and ensure package.json has 'type': 'module'.
