Connection closed when running tests

I am trying to get the karma-test-runner plugin to work but whenever I run the tests, it reports that the connection has been closed.

The log reports the following:

''' |Running 1 javascript test...

My grails test class is defined like this (I have been playing with different ports to see if that could be the issue, but it does not seem to be):

import de.is24.util.karmatestrunner.junit.KarmaTestSuiteRunner import org.junit.runner.RunWith

@RunWith(KarmaTestSuiteRunner.class) @KarmaTestSuiteRunner.KarmaRemoteServerPort(8888) @KarmaTestSuiteRunner.KarmaConfigPath("test/unit/javascript/karma.conf.js") class JavaScriptUnitTestKarmaSuite { }

My karma config file is:

/global module: false/ module.exports = function (config) { "use strict"; config.set({

    basePath: '.',

    frameworks: ['jasmine'],

    files: [
        /* files under test go here */
        'spec/**/*.js'
    ],

    reporters: ['remote'],

    plugins: [
        'karma-jasmine',
        'karma-junit-reporter',
        'karma-phantomjs-launcher',
        'karma-remote-reporter'
    ],

    remoteReporter: {
        host: 'localhost',
        port: '8888'
    },

     // web server port
    port: 9876,

    logLevel: config.LOG_INFO,

    autoWatch: false,

    browsers: ['PhantomJS'],

    singleRun: true
});

};

The config basically work, and can run the correct tests on the command line with

karma start karma.conf.js

Any ideas why the connection is being closed? I downgraded the karma-remote-reporter to 0.15 in case the more recent changes to use sockets directly could be the problem but it seems to report similar errors in both cases.

Hmm - the log seems to be fine.

To downgrade karma-remote-reporter to 0.1.5 was correct - the grails plugin is still incompatible with 0.2.0 (I will release a new version for grails this weekend).

Is the log output you posted - from karma-remote-reporter 0.1.5 ?

The log indicates that something on the grails-plugin (karma-test-runner) side closes the connection... maybe debugging the junit-karma-testrunner-1.4.jar::ResultReceiverServer::run/start gives you a clue about what's going on - I'm wondering why there's no error in the log (if you look at the code in case of an error we print an error message at least to the console...) ...

What grails version are you using - I'll try to reproduce the error...

Thanks for the quick response, I am using grails 2.4.4.

I have re-tried with 0.1.5 and the log is different to the one I posted (I tried a number of variations last night so may have lost track a bit).

The log output from 0.1.5 is as follows:

........Karma will be started with process builder args: [karma.cmd, start, C:\git\main\gnosis-app\test\unit\javascript\karma.conf.js] |Running 1 javascript test...

Thanks!

Hi again,

I updated my demo project git@github.com:FlorianGrundig/grails-angular-phonecat.git to grails 2.4.4 and run "grails test-app" with java 6 and 7 without any errors.

Can you please clone my demo project, run "npm install --save-dev", run "grails test-app unit:javascript" - is that working for you?

Update: I released a new version 0.2.3 which uses junit-karma-testrunner 0.1.6 and karma-remote-reporter 0.2.0. I updated my demo project git@github.com:FlorianGrundig/grails-angular-phonecat.git to use these new versions (please keep in mind that you have to manage/update your karma-remote-reporter manually).

Do you made any progress?

Hi, Thanks for the replies.

I tried the upgraded plugin in our project and it seemed to produce a different problem failing to parse JSON (which at least indicates something is now receiving the messages in the grails world!).

I cloned your phonecat project but that caused errors with karma not being a valid Win32 executable (the one that the tests point to inside of node_modules) - so I need to investigate that before I can get any further).

The log of running test-app is:

Hi,

Are you sure that you're using the 0.2.0 version of the karma-remote-reporter plugin? Your log output indicates that you're still using the previous 0.1.x version of karma-remote-reporter....

If you clone my test project and run it under windows - just remove @KarmaTestSuiteRunner.KarmaProcessName("./node_modules/karma/bin/karma") annotation at the test classes as they're valid only for linux environments...

Did it help you to get the demo project running?

Ah yes, commenting out the annotation worked on your project, thanks!

I will double check the karma-remote-reporter version and let you know

You are correct, I had not upgraded the version of the karma-remote-reporter plugin. After doing that it works great!

Thanks again for your help
