react-schema/test/utils/getTypeName.test.js

Use react like PropTypes for generic object validation.

import subject from '../../src/utils/getTypeName';
import { expect } from 'chai';
import PropTypes from '../../src/PropTypes';

describe('utils::getTypeName', () => {
  context('given a nilly', function () {
    it('returns undefined', function () {
      expect(subject()).to.equal(undefined);
    });
  });

  context('given an introspectable checker', function () {
    it('returns its pre-defined type', function () {
      expect(subject({ $meta: { type: 'foo' } })).to.equal('foo');
    });
  });

  describe('pre-defined types in PropTypes', function () {
    context('given PropTypes.string', function () {
      it('returns "string"', function () {
        expect(subject(PropTypes.string)).to.equal('string');
      });
    });

    context('given PropTypes.string.isRequired', function () {
      it('returns "string"', function () {
        expect(subject(PropTypes.string.isRequired)).to.equal('string');
      });
    });

    context('given PropTypes.string', function () {
      it('returns "string"', function () {
        expect(subject(PropTypes.string)).to.equal('string');
      });
    });

    context('given PropTypes.string.isRequired', function () {
      it('returns "string"', function () {
        expect(subject(PropTypes.string.isRequired)).to.equal('string');
      });
    });
  });
});
