Add possibility to stop a karma server

[nidi3]

When you start testacular with singleRun=false from within a script (Eg. build script) there is no way to stop it again (apart from killing the process manually).

Someting like

node testacular stop 9876

would be nice.

[vojtajina]

testacular stop --runner-port 9876

That reminds me we should use the same port for runner as well as web server, then it would be testacular stop --port 9876

[dignifiedquire]

1. We should add a short option so it would be just testacular stop -p 9876
2. When we are on that topic what about an option --detached for testacular start. This would allow for the process to run in the background and be stopped with this command.

[vojtajina]

+1 for --detached, testacular stop sounds good as well

[nidi3]

Any news regarding this issue?

[vojtajina]

Sorry, not a high priority now. I like the suggestion, but need to do other stuff first (eg. improve the communication protocol between karma server and karma run so that we can send other messages than just "run tests"; also refactor karma to only use single port for web server and the communication with other processes).

Send a pull request if you want it really badly ;-)

It is not a high priority to sto a server that you started? Wow!

[vojtajina]

@jasiedu Currently you can stop the server by pressing control+c or in --single-run mode it exits after executing all the tests.

I work on this project in my free time, if you want to help, that's awesome. Otherwise you fall into "trolling" group, which is ok, have fun ;-)

@dignifiedquire We can close this, right?

[dignifiedquire]

Yes we can thanks to you :)

It just hangs there after starting the server. This is whether or not I do karma start --single-run or set the singleRun: true directly in the config.
