What is the ideal location to install selenium-webdriver to work with NodeJS + Selenium + Mocha (On Windows)

I have just started to explore NodeJS with Selenium. Moving forward I will be working with NodeJS + Selenium + Mocha

1. Installed node.js:

   C:\Users\AtechM_03>node -v
   v6.11.2
   

2. Installed npm:

   C:\Users\AtechM_03>npm -v
   3.10.10
   

3. Configured nodeclipse as per http://www.nodeclipse.org/updates/ and my Project structure looks like:

Now, I am not sure about the exact location to install selenium-webdriver

4. Installed selenium-webdriver at the default location (through command-line) as per (http://www.nodeclipse.org/updates/)

   C:\Users\AtechM_03>npm install selenium-webdriver

5. Installed selenium-webdriver at the current project directory (through command-line) as per (https://dzone.com/articles/selenium-nodejs-and-mocha)

   C:\Users\AtechM_03\LearnAutmation\NodeProject>npm install selenium-webdriver

6. Wrote my first program through NodeJS-Selenium as first_test.js and it executes well.

Code:

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

    var driver = new webdriver.Builder().
       withCapabilities(webdriver.Capabilities.chrome()).
       build();

    driver.get('http://www.google.com');
    driver.findElement(webdriver.By.name('q')).sendKeys('simple programmer');
    driver.findElement(webdriver.By.name('q')).submit();
    driver.quit();

Execution :

    C:\Users\AtechM_03\LearnAutmation\NodeProject\Selenium>node first_test.js
    C:\Users\AtechM_03\LearnAutmation\NodeProject\Selenium>

My Question :

• How can I know from which location of selenium-webdriver is Testcase getting executed?
• How can I remove/uninstall the additional selenium-webdriver installation completely?
• How can I generate some granular trace level logs to know whats happening within?

While with Selenium-Java binding I add the jars at project level where as with Selenium-Python binding PyDev module binded the Python Home to Eclipse by default.

Any suggestions/pointers will be helpful.

Answer 1

How can I know from which location of selenium-webdriver is Testcase getting executed

The package search location order of nodejs as below:

1. project local packages, which at project_folder/node_modules
   
2. nodejs global packages, which at NPM_global_package_install_folder/node_modules, you can get where is PM_global_package_install_folder by executing command:
   npm config get prefix it print out a folder path
3. nodejs build-in module, which is inside node.exe

If your project local packages includes this package, nodejs will use it from local pacakges, otherwise use if from global package, if gloal packages not has this package, noejs will report module 'selenium-webdriver' not found error.

How can I remove/uninstall the additional selenium-webdriver installation completely

1. In general, to uninstall project local package, execute npm uninstall selenium-webdriver under project folder, or npm uninstall selenium-webdriver -g to uninstall global package.

How can I generate some granular trace level logs to know whats happening within

Actually, selenium server supply a detail log of each selenium API call, not sure it's you wanted.
