How to use the @terascope/job-components.registerApis function in @terascope/job-components

// used for testing so we dont have to pollute the process env in testing
    const {
        processAssignment = context.__test_assignment || process.env.assignment,
        execution = _parseJob(context.__test_job || process.env.job),
    } = config;

    const isSlicer = processAssignment === 'execution_controller';
    const assetPath = execution.assets ? context.sysconfig.teraslice.assets_directory : null;
    const jobAssets = execution.assets ? execution.assets : [];

    const opLoader = new OperationLoader({
        assetPath,
        terasliceOpPath: path.join(__dirname, '..', '..'),
    });

    registerApis(context, execution);

    function _instantiateJob() {
        let slicer = null;
        const reporter = null;
        let queue = [];

        if (context.sysconfig.teraslice.reporter) {
            throw new Error('reporters are not functional at this time, please do not set one in the configuration');
        }
        // TODO fix released api
        function executionApi() {
            return {
                reader: queue[0],
                queue,
                config: execution,
                reporter,

constructor({
        op,
        context,
