Under my Angular 6 app , i ve this config
karma.conf.js:
// Karma configuration file, see link for more information
// https://karma-runner.github.io/1.0/config/configuration-file.html
module.exports = function (config) {
config.set({
basePath: '',
frameworks: ['jasmine', '@angular-devkit/build-angular'],
plugins: [
require('karma-jasmine'),
require('karma-chrome-launcher'),
require('karma-jasmine-html-reporter'),
require('karma-coverage-istanbul-reporter'),
require('@angular-devkit/build-angular/plugins/karma')
],
client:{
clearContext: false // leave Jasmine Spec Runner output visible in browser
},
mime: {
'text/x-typescript': ['ts','tsx']
},
coverageIstanbulReporter: {
dir: require('path').join(__dirname, 'coverage'),
reports: [ 'html', 'lcovonly' ],
fixWebpackSourcePaths: true
},
reporters: config.angularCli && config.angularCli.codeCoverage
? ['progress', 'coverage-istanbul']
: ['progress', 'kjhtml'],
port: 9876,
colors: true,
logLevel: config.LOG_INFO,
autoWatch: true,
browsers: ['Chrome'],
browserDisconnectTimeout: 10000,
browserDisconnectTolerance: 3,
browserNoActivityTimeout: 60000,
flags: [
'--disable-web-security',
'--disable-gpu',
'--no-sandbox'
],
singleRun: true,
concurrency: Infinity
});
};
An i ve a file , test.ts ; which is supposed to configurate the test running :
// This file is required by karma.conf.js and loads recursively all the .spec and framework files
import 'zone.js/dist/long-stack-trace-zone';
import 'zone.js/dist/proxy.js';
import 'zone.js/dist/sync-test';
import 'zone.js/dist/jasmine-patch';
import 'zone.js/dist/async-test';
import 'zone.js/dist/fake-async-test';
import { getTestBed } from '@angular/core/testing';
import {
BrowserDynamicTestingModule,
platformBrowserDynamicTesting
} from '@angular/platform-browser-dynamic/testing';
// Unfortunately there's no typing for the `__karma__` variable. Just declare it as any.
declare var __karma__: any;
declare var require: any;
// Prevent Karma from running prematurely.
__karma__.loaded = function () {};
// First, initialize the Angular testing environment.
getTestBed().initTestEnvironment(
BrowserDynamicTestingModule,
platformBrowserDynamicTesting()
);
// Then we find all the tests.
const context = require.context('./', true, /my-component.component.spec.ts/);
// And load the modules.
context.keys().map(context);
// Finally, start Karma to run the tests.
__karma__.start();
i may let me filter file to be tested
for example i want to run this one : my-component.component.spec.ts
But that it not running , and it seems that it lacks some config in the karma.conf to run the test.ts
Sugesstions ?
change this line
const context = require.context('./', true, /my-component.component.spec.ts/);
with this
const context = require.context('./', true, /my-component\.component\.spec\.ts$/);
to avoid the special character '.'
