I have setup test environment according to  
[http://lynckia.com/licode/travis-webrtc.html](http://lynckia.com/licode/travis-webrtc.html)  
then,I try to run all test cases defined at /test/nuve-test.js , test cases  
can be found at  
[https://github.com/ging/lynckia/blob/master/test/nuve-test.js](https://github.com/ging/lynckia/blob/master/test/nuve-test.js)  
3 test cases failed .

test steps:

1. run ./script/initLynckia.sh
2. run ./script/ [initBasicExample.sh](http://initBasicExample.sh)
3. open [http://localhost:3001](http://localhost:3001) at browser and make sure environment is  
correct.
4. run “npm test” at command line  
4 test cases passed while last 3 test cases failed.  
here is test result info  
Chrome 27.0 (Linux) nuve-test _should publish stream in room FAILED_  
timeout: timed out after 5000 msec waiting for something to happen  
Chrome 27.0 (Linux) SLOW 5.117 secs: nuve-test should publish stream in

Any comments or suggestion ?

Hi Alice,

Thanks for the warning! We’re taking a glance at it since it seems the  
–use-fake-media-device flag of Chrome doesn’t work properly. We’ll let you  
know when we find a solution.

Anyway, any advice from someone in the list who is playing with this  
Chrome’s feature will be welcome! Thanks!

Cheers,

Hi, Javier  
I can send a pull request in Github 🙂  
A another question : why you set chrome\_bin =“DISPLAY=:99” at Cakefile ?  
I can only launch chrome with “DISPLAY=:0”

Thanks

Hi, Javier  
I have debug the test cases again . It failed because stream-added event  
always triggered later than timeout time (5000 msec) after we call  
room.publish(localStream);  
If we call room.publish(localStream) at test case ‘should connect to room’  
and add ‘waits(20000)’ before ‘room.addEventListener(“stream-added”,  
function(msg) ~’  
It works now.On Tuesday, June 4, 2013 11:21:12 PM UTC+8, Javier Cerviño wrote:

Hi Alice,

Thanks a lot! That’s a very interesting fix for the tests since the were  
partially broken. You can send a pull request in Github with the commit if  
you want. If not, we’ll do it.
