const lockfileInfo = require('lockfile-info');
const assert = require('assert');

lockfileInfo().then((results) => {
assert.deepEqual(Object.keys(results), [
'hasPackageJSON',
'hasNodeModulesDir',
'hasLockfile',
'hasPackageLock',
'hasShrinkwrap',
'lockfileVersion',
]);

assert.equal(typeof results.hasPackageJSON, 'boolean');
assert.equal(typeof results.hasNodeModulesDir, 'boolean');
assert.equal(typeof results.hasLockfile, 'boolean');
assert.equal(typeof results.hasPackageLock, 'boolean');
assert.equal(typeof results.hasShrinkwrap, 'boolean');
assert.equal(typeof results.lockfileVersion, 'number'); // NaN, 1, 2, or 3
