An error occurred while trying to start ChromeDriver: cannot resolve path: "/node_modules/.bin/chromedriver"
Finally, I got a solution when I show his git account of the tutorial also post the solution too.
I just need to change my file nightwatch.conf.js
module.exports = { "src_folders" : ["tests"], "webdriver" : { "start_process": true, "server_path": require('chromedriver').path, "port": 9515 }, "test_settings" : { "default" : { "desiredCapabilities": { "browserName": "chrome" } } }}
