esplan

Description

Count assertions in your test cases with static code analysis before execution and wait until all assertions are completed.

Example

Input:

var esplan = require('esplan');
var assert = esplan.register(require('assert'));

describe('Promise', function() {
    it('can not detect an assertion error in `then` function', function() {
        mayBeResolve().then(function(value) {
            assert.equal(value.length, 2);
            assert.equal(value[0], 'foo');
            assert.equal(value[1], 'bar');
        });
    });
});

Output:

var esplan = require('esplan');
var assert = esplan.register(require('assert'));

describe('Promise', function () {
    // `$$done` is added!
    it('can not detect an assertion error in `then` function', function($$done) {
        assert.$$plan(this, 3, $$done); // this line is inserted!
        mayBeResolve().then(function (value) {
            assert.equal(value.length, 2);
            assert.equal(value[0], 'foo');
            assert.equal(value[1], 'bar');
        });
    });
});

Result (If mayBeResolve() returns wrong value ['foo', 'wrong!']):

Error: Expected 3 assertions, but actually 2 assertions called
