/**
 * Fork a Verdaccio process with a custom configuration.
 *
 * Usage:
 *
 *  - Fork the process within the beforeAll body.
 *  - Define a storage (use a specific name)
 *  - Define a unique port (be careful with conflicts)
 *  - Set a configuration
 *  - await / mockServer
 *  - call done();
 *
 *  beforeAll(function(done) {
      const store = path.join(__dirname, '../partials/store/test-profile-storage');
      const mockServerPort = 55544;
      rimraf(store, async () => {
        const parsedConfig = parseConfigFile(parseConfigurationProfile());
        const configForTest = _.assign({}, _.cloneDeep(parsedConfig), {
          storage: store,
          auth: {
            htpasswd: {

        app = await endPointAPI(configForTest);
        mockRegistry = await mockServer(mockServerPort).init();

   On finish the test we must close the server

   afterAll(function(done) {
    mockRegistry[0].stop();
    done();
   });
