@peter.nguyentr: anyone knows how to enable local testing for BS config?

@lukoyanov94:

const browserstack = require("browserstack-local");
// to avoid same names in simultaneous launch for multiple runner
const _localIdentifier = `local_${Date.now()}_${Math.random().toString(36).substring(7)}`;

// take credentials from environment variables
const _user = process.env.BS_CREDS_USR;
const _key = process.env.BS_CREDS_PSW;

exports.config = {
  ...
  bootstrap: function(done) {
    if (_user && _key) {
      console.log(`Connecting local. Identifier: "${_localIdentifier}"`);

      module.exports.bs_local = new browserstack.Local();
      module.exports.bs_local.start(
        {
          onlyAutomate: true,
          key: _key,
          localIdentifier: _localIdentifier
        },
        function(error) {
          if (error) {
            console.log(error);
            return error;
          }
          console.log("Connected. Now testing...");
          done();
        }
      );
    } else done();
  },
  teardown: function(done) {
    if (_user && _key) {
      module.exports.bs_local.stop(() => {
        console.log("Disconnected");
        done();
      });
    } else done();
  },
  ...
}

@peter.nguyentr: thanks so much,
