Protractor Unable to execute test cases in Chome using webdriver-manager - protractor

Protractor is unable to start test cases in chrome browser using webdriver-manager.
I followed the instructions given here https://www.protractortest.org/#/
and faced the below error.

I am using Ubutu machine and trying to run a basic scenario. Selenium Server seems to be up and running in http://localhost:4444/, as mentioned. Can any one please suggest ?

Answer 1

Make your config as below
exports.config = {
directConnect: true,
// Capabilities to be passed to the webdriver instance.
capabilities: {
'browserName': 'chrome'
},
// Framework to use. Jasmine is recommended.
framework: 'jasmine',
// Spec patterns are relative to the current working directory when
// protractor is called.
specs: ['example_spec.js'],
// Options to be passed to Jasmine.
jasmineNodeOpts: {
defaultTimeoutInterval: 30000
}
};
Run npm i webdriver-manager & webdriver-manager update from your project folder.
if you get No Update config found error when trying to run the test run node node_modules/protractor/bin/webdriver-manager update
Now run your test
Hope it helps you

Answer 2

From this answer it appears that you can add --disable-dev-shm-usage when running on Linux machines to resolve this issue.
conf.js
exports.config = {
seleniumAddress: 'http://localhost:4444/wd/hub',
specs: ['todo-spec.js'],
capabilities: [
{
browserName: 'chrome',
chromeOptions: { args: ["--disable-dev-shm-usage"] },
},
};
Can you give this a try and let me know if it works? Thanks

Try running your job using the following chrome arg:
--capabilities.chromeOptions.args="no-sandbox"
