Package Exports

thunk-test

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (thunk-test) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

ThunkTest

Modular testing for JavaScript. Set up tests as thunks, then execute them with a call.

ThunkTest(
  'pipe: awesome username generator',
  pipe([
    string => string.toUpperCase(),
    string => `x${string}x`,
    string => `X${string}X`,
    string => `x${string}x`,
    string => `_${string}_`,
  ]))
  .case('deimos', '_xXxDEIMOSxXx_') // objects deep equal, otherwise strict equal
  .case('|', result => assert.equal(result, '_xXx|xXx_')) // can supply a callback
  .case('?', async result => assert.equal(result, '_xXx?xXx_')) // async ok
  .throws(1, new TypeError('string.toUpperCase is not a function'))
  .throws(null, (err, arg0) => {
    assert.strictEqual(arg0, null)
    assert.strictEqual(err.name, 'TypeError')
    assert.strictEqual(err.message, 'Cannot read property \'toUpperCase\' of null')
  })()
// -- pipe: awesome username generator
//  ✓ pipeline('deimos') -> '_xXxDEIMOSxXx_'
//  ✓ pipeline('|') -> result => assert.equal(result, '_xXx|xXx_')
//  ✓ pipeline(1) throws TypeError: string.toUpperCase is not a function
//  ✓ pipeline(null) throws; (err, arg0) => {
//       assert.strictEqual(arg0, null)
//       assert.strictEqual(err.name, 'TypeError')
//       assert.strictEqual(err.message, 'Cannot read property \'toUpperCase\' of null')
//     }
//  ✓ pipeline('?') -> async result => assert.equal(result, '_xXx?xXx_')
//  ✓ pipeline(NaN) throws; async (err, arg0) => {
//       assert.strictEqual(arg0, NaN)
//       assert.strictEqual(err.name, 'TypeError')
//       assert.strictEqual(err.message, 'string.toUpperCase is not a function')
//     }

ThunkTest is a function-first testing library.
