Just starting out with Polymer and Unit Testing. I was trying out the activity on this page https://www.polymer-project.org/2.0/docs/tools/tests but I couldn't get polymer test to run. So I tried running polymer test --verbose and end up getting this error:
Error: Selenium server did not start.Another Selenium process may already be running or your java version may be out of date.
error: cli runtime exception: Error: Selenium server did not start.Another Selenium process may already be running or your java version may be out of date. error: Error: Selenium server did not start.Another Selenium process may already be running or your java version may be out of date. at ChildProcess.errorIfNeverStarted (C:\Users\Eleonor Somosot\AppData\Roaming\npm\node_modules\polymer-cli\node_modules\selenium-standalone\lib\start.js:141:15) at emitTwo (events.js:106:13) at ChildProcess.emit (events.js:191:7) at Process.ChildProcess._handle.onexit (internal/child_process.js:215:12)
Hoping someone could help me with this and maybe explain. Thanks..
Hit below url for shut down already running selenium server on port 4444.
http://localhost:4444/selenium-server/driver/?cmd=shutDownSeleniumServer
If selenium server is already running on port 4444 then it will shut down the server and says OK if selenium is not running on this port 4444 then by hitting above url will give you "Unable to connect"
If no server was running, Tuned out the java version was in cause. Make sure you are running java 7 or higher:
java -version
