Bug Fixes

Breaking Changes

• Replace default exported unassert with named exported unassertAst

unassert function is removed in favor of named exports aiming ESM era. Please use unassert.unassertAst instead.

before:

const unassert = require('unassert');

after:

const { unassertAst } = require('unassert');

• Replace AST matcher with simpler and robust logic

Configuration options are simplified a lot. Patterns are aggregated into modules.

before:

{
  assertionPatterns: [
    'assert(value, [message])',
    'assert.ok(value, [message])',
    'assert.equal(actual, expected, [message])',
    'assert.notEqual(actual, expected, [message])',
    'assert.strictEqual(actual, expected, [message])',
    'assert.notStrictEqual(actual, expected, [message])',
    'assert.deepEqual(actual, expected, [message])',
    'assert.notDeepEqual(actual, expected, [message])',
    'assert.deepStrictEqual(actual, expected, [message])',
    'assert.notDeepStrictEqual(actual, expected, [message])',
    'assert.fail(actual, expected, message, operator)',
    'assert.throws(block, [error], [message])',
    'assert.doesNotThrow(block, [message])',
    'assert.ifError(value)',
    'console.assert(value, [message])'
  ],
  requirePatterns: [
    'assert = require("assert")'
  ],
  importPatterns: [
    'import assert from "assert"',
    'import * as assert from "assert"'
  ]
}

after:

{
  modules: [
    'assert',
    'assert/strict',
    'node:assert',
    'node:assert/strict'
  ]
}

• Drop power-assert support from default patterns since power-assert works transparently

Move power-assert support away from default patterns since power-assert empowers default assert function transparently, so should not be required explicitly. If power-assert is still required explicitly, add 'power-assert' to modules in customized configuration.

after:

{
  modules: [
    'assert',
    'assert/strict',
    'node:assert',
    'node:assert/strict',
    'power-assert'
  ]
}
