我正在尝试围绕ng2-admin project编写一些测试。我在设置测试环境时遇到问题。测试将用typescript编写，因此karma.config.js还需要指定一个转换器。但是在尝试运行它时遇到错误。
karma.config.js
module.exports = function(config) {
config.set({
basePath: '.',
frameworks: ['jasmine', 'requirejs'],
files: [
// paths loaded by Karma
{pattern: 'node_modules/angular2/bundles/angular2-polyfills.js', included: true, watched: true},
{pattern: 'node_modules/systemjs/dist/system.src.js', included: true, watched: true},
{pattern: 'node_modules/rxjs/bundles/Rx.js', included: true, watched: true},
{pattern: 'node_modules/angular2/bundles/angular2.dev.js', included: true, watched: true},

// paths to support debugging with source maps in dev tools
{pattern: 'src/app/**/*.ts', included: true, watched: true},
{pattern: 'src/test/**/*.ts', included: true, watched: true},
],
// proxied base paths
proxies: {
// required for component assests fetched by Angular's compiler
},
port: 9876,
logLevel: config.LOG_INFO,
colors: true,
autoWatch: true,
browsers: ['Chrome'],
// Karma plugins loaded
plugins: [
'karma-jasmine',
'karma-coverage',
'karma-requirejs',
'karma-chrome-launcher',
'karma-typescript-preprocessor'
],
// Coverage reporter generates the coverage
reporters: ['progress', 'dots', 'coverage'],
// Source files that you wanna generate coverage for.
// Do not include tests or libraries (Files used by Istanbul)
preprocessors: {
'src/app/**/*.ts': 'typescript',
'src/test/**/*.ts': 'typescript',
'dist/**/!(*spec).js': ['coverage']
},
coverageReporter: {
reporters:[
{type: 'json', subdir: '.', file: 'coverage-final.json'}
]
},
singleRun: true
})
};
果报测试shim.js
// Tun on full stack traces in errors to help debugging
Error.stackTraceLimit = Infinity;
jasmine.DEFAULT_TIMEOUT_INTERVAL = 1000;
// // Cancel Karma's synchronous start,
// // we will call `__karma__.start()` later, once all the specs are loaded.
__karma__.loaded = function() {};
System.config({
packages: {
'base/dist': {
defaultExtension: false,
format: 'cjs',
map: Object.keys(window.__karma__.files).filter(onlyAppFiles).reduce(createPathRecords, {})
}
}
});
System.import('angular2/src/platform/browser/browser_adapter')
.then(function(browser_adapter) { browser_adapter.BrowserDomAdapter.makeCurrent(); })
.then(function() { return Promise.all(resolveTestFiles()); })
.then(function() { __karma__.start(); }, function(error) { __karma__.error(error.stack || error); });
function createPathRecords(pathsMapping, appPath) {
// creates local module name mapping to global path with karma's fingerprint in path, e.g.:
// './vg-player/vg-player':
// '/base/dist/vg-player/vg-player.js?f4523daf879cfb7310ef6242682ccf10b2041b3e'
var pathParts = appPath.split('/');
var moduleName = './' + pathParts.slice(Math.max(pathParts.length - 2, 1)).join('/');
moduleName = moduleName.replace(/\.js$/, '');
pathsMapping[moduleName] = appPath + '?' + window.__karma__.files[appPath];
return pathsMapping;
}
function onlyAppFiles(filePath) {
return /\/base\/dist\/(?!.*\.spec\.js$).*\.js$/.test(filePath);
}
function onlySpecFiles(path) {
return /\.spec\.js$/.test(path);
}
function resolveTestFiles() {
return Object.keys(window.__karma__.files) // All files served by Karma.
.filter(onlySpecFiles)
.map(function(moduleName) {
// loads all spec files via their global module names (e.g.
// 'base/dist/vg-player/vg-player.spec')
return System.import(moduleName);
});
}
这是怪物package.json：

测试中的类（truncate.pipe.ts）：
import {Pipe} from '@angular/core'
@Pipe({
name: 'truncate'
})
export class Truncate {
transform(value, arg1, arg2) : string {
!arg1 ? arg1 = 10 : arg1;
!arg2 ? arg2 = '' : arg2;
return value.length > arg1 ? value.substring(0, arg1) + arg2 : value;
}
}
样本测试（truncate.pipe.spec.ts）：
import {Truncate} from '../app/pages/dashboard/quotas/pipes/truncate.pipe.ts';
describe('MyPipe Tests', () => {
let pipe: Truncate;
beforeEach(() => {
pipe = new Truncate();
});
it('Should truncate 10 characters ', () => {
var result = pipe.transform('blah blah blah', null,null);
expect(result).toEqual('blah blah ');
});
});
任何帮助高度赞赏。
