Facing issues with Karma-PhantomJS-Launcher in unit testing #208

Closed Asiq closed 7 years ago

Asiq commented 7 years ago

I have configured the Karma Plugins with karma-phantomjs-launcher My Configurations and Error List. Karma.conf.js : module.exports = function (config) { config.set({ basePath: '', frameworks: ['jasmine', 'angular-cli'], plugins: [ require('karma-jasmine'), require('karma-chrome-launcher'), require('karma-phantomjs-launcher'), require('karma-remap-istanbul'), require('karma-mocha-reporter'), require('angular-cli/plugins/karma') ], files: [ { pattern: './src/test.ts', watched: false } ], preprocessors: { './src/test.ts': ['angular-cli'] }, mime: { 'text/x-typescript': ['ts','tsx'] }, remapIstanbulReporter: { reports: { html: 'coverage', lcovonly: './coverage/coverage.lcov' } }, angularCli: { config: './angular-cli.json', environment: 'dev' }, reporters: config.angularCli && config.angularCli.codeCoverage ? ['mocha', 'karma-remap-istanbul'] : ['mocha'], port: 9876, colors: true, logLevel: config.LOG_INFO, cordovaSettings: { platforms: ['android', 'ios'], mode: 'emulate', hostip: '10.0.2.2', target: '0468de2a213eae29', plugins: [ 'org.apache.cordova.console' ] }, browsers: ['PhantomJS'], singleRun: true }); };

package.json file this is my devDependencies:

"devDependencies": { "@ionic/app-scripts": "0.0.47", "@types/jasmine": "2.5.38", "angular-cli": "1.0.0-beta.24", "codelyzer": "~0.0.26", "jasmine-core": "2.5.2", "jasmine-spec-reporter": "2.7.0", "karma": "1.3.0", "karma-chrome-launcher": "2.0.0", "karma-phantomjs-launcher": "1.0.2", "karma-cli": "1.0.1", "karma-jasmine": "1.1.0", "karma-mocha-reporter": "2.2.1", "karma-remap-istanbul": "0.2.2", "protractor": "4.0.13", "protractor-jasmine2-screenshot-reporter": "0.3.2", "ts-node": "1.7.2", "tslint": "4.1.1", "tslint-eslint-rules": "3.2.0", "typescript": "2.0.10" },

When i run the unit testing npm test .. Missing error handler on socket. TypeError: Cannot read property 'set' of null at KarmaRemapIstanbul.onBrowserComplete

Even Code Coverage is not showing any result.

Hey,

I've wasted enough of my life trying to support (and debug) PhantomJS, inside and outside of this repo, to have no interest whatsoever in doing so here.

Essentially we use whatever ng-cli use upstream.

Have dig around and see if you can find anything with ng-cli and Phantom:

Looking at the error message, you might try to disable code coverage to see if it gets you anywhere.

Sorry to not be more helpful, but I don't have the time to support anything test-wise outside of ng-cli.

Thanks

Hey,

Thanks for your comments, Here im using angular ng-cli way to achieved the code coverage and unit test cases , basically i followed your clicker project as taking an example of writing unit test cases for my project. It was really helped me lot.

Now my goal is to disconnect the karma runner after first time test cases are ran.(the reason behind is to execute my Jenkins command after unit test cases).

could you please guide me on this, How do I can achieved it.

Thanks
