Plain JS config: How to load plugins?

[dwbruhn]

The plain JS config example creates the plugin section as follows:

module.exports = {
    plugins: {
        view: {
            module: "nemo-view"
        }
    },

But nemo.view is undefined:

describe('@firstTest@', function () {
  it('should load a website', async function () {
    console.log('NEMO VIEW', this.nemo.view);
    await this.nemo.driver.get(this.nemo.data.baseUrl);
  });
});

Output:

NEMO VIEW undefined

I've tried both module: require.resolve("nemo-view") and module: require("nemo-view") but neither gets nemo-view to load.

Enabling DEBUG=nemo-core:log only shows snap being loaded:

nemo-core:log register plugin snap +0ms
  nemo-core:log plugin.registration fulfill with 1 plugins. +1ms

So far I've tracked it down to this function:

nemo/lib/runner/mocha.js

Lines 46 to 48 in aaec89b

	.then((nemoCoreConfig) => {
	NemoBaseConfig.merge(nemoCoreConfig);
	return NemoCore(NemoBaseConfig);

When running with a JSON config, the nemoCoreConfig has nemo-view in the plugins section:

nemoCoreConfig plugins:  { view:
   { module: 'nemo-view',

But when running with plain JS, the plugins section of nemoCoreConfig is undefined:

nemoCoreConfig plugins:  undefined

(In both cases, snap is in the NemoBaseConfig which gets merged with the nemoCoreConfig.)

So here's the problem:

nemo/lib/runner/mocha.js

Lines 40 to 44 in aaec89b

	// plain JS config use case
	return NemoCore.Configure({
	driver: driverConf,
	data: dataConf
	});

If there's no instanceConfig.basedir (which is the case when you're using an explicit/implicit config file), this generates a nemoCoreConfig with no plugin information.

One possible (and kinda ugly) fix is to pass program.configFile all the way down here so if instanceConfig.basedir is undefined, it will read the config from the config file instead. This like what's being done in _nemo:

nemo/bin/_nemo

Lines 87 to 99 in aaec89b

	if (program.baseDirectory) {
	// baseDirectory case
	return NemoFactory.configure(program);
	}
	else if (program.configFile) {
	// explicit config file case
	return NemoFactory.configureJS(program);
	}
	try {
	// implicit config file case
	require(path.resolve(process.cwd(), 'nemo.config'));
	program.configFile = path.resolve(process.cwd(), 'nemo.config');
	return NemoFactory.configureJS(program);

BTW while debugging this I noticed that the -C option is kind difficult with JSON files now. It doesn't support comments in JSON, and if you use shortstop handlers you have to back up out of the node_modules/nemo-core/etc. directory like this:

"data": "require:../../../../test/functional/data/data.json"
