var webdriver = require('selenium-webdriver'),

.build();
module.exports = driver;
function exitHandler(options, err) {
driver.quit()
}
//do something when app is closing
process.on('exit', exitHandler.bind(null,{cleanup:true}));
//catches ctrl+c event
process.on('SIGINT', exitHandler.bind(null, {exit:true}));
//catches uncaught exceptions
process.on('uncaughtException', exitHandler.bind(null, {exit:true}));

Answer 1

Before using any driver instance check whether that driver session is active or not here we have two cases
1. session id is present
if session id present then we can go further
2. session id doesn't exist
so we can't go further either stop
