Jenkins Slave (service) , cannot detect protractor - jenkins

Question

We are using slave as service and we r trying to run protractor with simple batch file after calling to npm install , but from some reason protractor was not detected, do u know what could be the reason/problem?
if i use web option (slave) for running job - everything went fine,
BTW - I try to set the service with user that allowed to run the test, and also set node in PATH, but nothing help
Appreciate your comments,
Thanks

Answer 1

because you install protractor as a global package, So you should use webdriver-manager from global package install folder. The current folder where you execute npm install -g protractor has no webdriver-manager this cmd/binary. So jenkins report can't find webdriver-manager in current folder or PATH.
For best practice, you should add protractor as your nodejs project's dependency through npm install -S protractor before you write script, after do that, you will found 'protractor' will be add into package.json.
When others who get your source code, he only need to execute npm install under folder where package.json insides to get all dependencies installed.
After npm install done, the webdriver-manager will be found <package.json file inside folder>\node_modules\.bin\webriver-manager
So your cmd should write down as following:
pwd
ls -l "${WORKSPACE}"
cd /d <package.json file inside folder>
npm install
node_modules\.bin\webdriver-manager update
node_modules\.bin\protractor conf.js
