metatests

metatests is an extremely simple to use test framework and runner for Metarhia technology stack built on the following principles:

• Test cases are files, tests are either imperative (functions) or declarative (arrays and structures).

• Assertions are done using the built-in Node.js assert module. The framework also provides additional testing facilities (like spies).

• Tests can be run in parallel.

• All tests are executed in isolated sandboxes. The framework allows to easily mock modules required by tests and provides ready-to-use mocks for timers and other core functionality.

• Testing asynchronous operations must be supported.

• Testing pure functions without asynchronous operations and state can be done without extra boilerplate code using DSL based on arrays.

  mt.case('Test common.duration', { common }, {
    // ...
    'common.duration': [
      ['1d',     86400000 ],
      ['10h',    36000000 ],
      ['7m',     420000   ],
      ['13s',    13000    ],
      ['2d 43s', 172843000],
      // ...
    ],
    // ...
  });

  (Prior art)

• The framework must work in Node.js and browsers (using Webpack or any other module bundler that supports CommonJS modules and emulates Node.js globals).
