BMO MOCKER

This module is meant to help you test your modules faster. It loads your dependencies and configuration for your app and provides you an interface to swap out modules before building your module for testing. Currently the module assumes that your directory structure has a config and dependencies folder in the directory where you run your test process. Those folders should contain your bmo config and your dependency modules.

#Example usage

import mocker from '@b-mo/mocker';
import fooModule from '.';

const container = mocker();
container.mock('barDep', { barSvc:()=>[{ baz:'bar' }] });
const fooInstance = await container.build(fooModule);
expect(fooInstance.getBars()).toEqual({ baz:'bar' });

#API

const container = mocker({ config, dependencies })

config - An object containing values you wish to override in your test configuration.
dependencies - A set of modules to use as dependencies instead of the default ones.
returns an IOC container for building your test modules.

**[DEPRECATED]**
container.extend(package)

either an object with a dependencies key or the name of a package
that exposes a dependencies property. The dependencies will be included
when the container is built.

This function is deprecated, declare extensions as a part of you "bmo" config in the project's package.json

container.mock(dependencyName, dependencyValue);

dependencyName - A json path for the mock you wish to set.
dependency - the thing you want to be passed to the module instead of the normal module.
returns the container for chaining

container.config(configPath, configValue)

configPath - A json path for the value you want to override in the config
configValue - the value you want instead of the default one.
returns the container for chaining

const moduleInstance = await container.build(module)

module - the base module you would like to be instantiated
returns the created module with the mocked values instead of the normal dependencies.

Performance notes: The container will load and resolve your projects dependencies when you first call build. Subsequent calls to build should be faster assuming you do not re-create the whole container and re-use the same container to build new module instances.
