The npm script for running Protractor is encountering an error

Currently, I am facing an issue while trying to execute the conf.js file using an npm script. The conf.js file is generated within the JSFilesRepo/config folder after running the tsc command as I am utilizing TypeScript in conjunction with protractor-jasmine.

When I navigate to the cmd at the package.json level and input the following command:

protractor JSFilesRepo/config/conf.js

it runs smoothly. However, when attempting to run it through an npm script (npm run test) from the package.json level, I encounter an error

"scripts": {   
    "test": "node_modules/.bin/protractor JSFilesRepo/config/conf.js",
  },

Error message: Error: Could not locate update-config.json. Please execute 'webdriver-manager update' to fetch binaries.

I have already updated webdriver-manager. My assumption is that there might be a path-related issue.

Answer №1

When you run 'protractor JSFilesRepo/config/conf.js', it utilizes the global protractor setup for which you have already executed 'webdriver-manager update'.

However, when you run 'node_modules/.bin/protractor JSFilesRepo/config/conf.js', it uses the local protractor version within your project, and it seems like you haven't yet run 'webdriver-manager update' specifically for this local instance.

To fix this, simply execute '

./node_modules/protractor/bin/webdriver-manager update
' from the root directory of your project.

Answer №2

Include the following script in your package.json:

"scripts": {   
    "WDupdate":"node node_modules/protractor/node_modules/webdriver-manager/bin/webdriver-manager update",
    "test": "node_modules/.bin/protractor JSFilesRepo/config/conf.js"
 }

To execute, first run WDupdate, then proceed with your test command.
