Simple Test Recorder for Redux

Installation

npm install redux-simple-test-recorder --save

Usage

The first thing that you need to do is to create a test generator function that is suitable for your application, here's an example for a tape test:

const reducer = (state, {type, payload}) => {
    ...
};

const testGenerator = (actions) => {
    const asserts = actions.map((action, index) => {
        return `test('${action.action.type} (action index ${index}) should correctly update state', function(assert) {
          var action = actions[${index}];
          var result = reducer(action.prevState, action.action);
          assert.ok(equality(result, action.nextState), 'state updated correctly');
          assert.end();
        });`
    }).join('\n\n');

    return (`
    var test = require('tape');
    ${reducer.toString()}
    var equality = (result, nextState) => JSON.stringify(result) === JSON.stringify(nextState);
    var actions = ${JSON.stringify(actions, null, 2)};

    ${asserts}`
    );
};

Than you should build and use the middleware in your store

import reduxRecord from 'redux-simple-test-recorder';

const record = reduxRecord(testGenerator);
export const store = createStore(reducer, applyMiddleware(record.middleware));
export const recordInterface = record.recordInterface;

Now you can use the record interface to start recording your tests

recordInterface.startRecord();
//Do something on the UI...
const test = recordInterface.stopRecord();
console.log(test);

Enjoy your generated tests! :)
