mocha-json-deserialize

☕️ A Mocha.js JSON deserializer ☕️

Pairs well with mocha-json-serialize-reporter!

What is this for?

This can be used to revive the JSON output from mocha-json-serialize-reporter back into a Mocha Suite.

• This package is used by mocha-json-runner to "playback" a previously run mocha test suite that has been serialized to JSON. You could then run the JSON through another Mocha reporter such as Spec.

• The deserialized Mocha Suite could also be added to an existing mocha test suite.

Example

See Examples

// Run this with mocha:
// mocha examples/mocha.js
 
const mochaJsonDeserialize = require('mocha-json-deserialize');
 
// stringify is optional, can take a JSON string or an Object
const json = JSON.stringify({
  suite: {
    title: '',
    tests: [
      { title: 'passing test', state: 'passed' },
      { title: 'failing test', state: 'failed', err: { message: 'FAIL' } },
      { title: 'pending test', pending: true },
      {
        title: 'a slow test',
        state: 'passed',
        speed: 'slow',
        duration: 5,
        slow: 3,
      },
    ],
  },
});
 
const rootSuite = mochaJsonDeserialize(json);
rootSuite.title = 'A deserialized suite';
 
describe('A describe block', function() {
  this.addSuite(rootSuite);
 
  describe('A real suite', function() {
    it('should have a passing test', function() {});
  });
});

Output:

  A describe block
    A deserialized suite
      ✓ passing test
      1) failing test
      - pending test
      ✓ a slow test (5ms)
    A real suite
      ✓ should have a passing test
 
 
  3 passing (7ms)
  1 pending
  1 failing
 
  1) A describe block
       A deserialized suite
         failing test:
