Karma / Jasmine问题与Angular2项目 [英] Karma/Jasmine Issues w/ Angular2 Project
问题描述
我有一个项目如下:
我试图让Karma / Jasmine作为测试框架。我尝试复制这个项目:
我不确定我的文件路径是否正确 karma-test-shim.js
/ karma.conf.js
因为我还是处理npm / node项目的新手。
这是我的 karma-test-shim.js
(文件路径位于 var moduleName
和 onlyAppFiles
function):
//在完整堆栈跟踪中调整错误以帮助调试
Error.stackTraceLimit = Infinity;
jasmine.DEFAULT_TIMEOUT_INTERVAL = 1000;
// //取消Karma的同步启动,
// //我们将在加载所有规格后调用`__karma __。start()`。
__karma __。loaded = function(){};
System.config({
packages:{
'base / src / app':{
defaultExtension:false,
format :'register',
map:Object.keys(window .__ karma __。files)。
filter(onlyAppFiles)。
reduce(function createPathRecords(pathsMapping,appPath){
/ /创建本地模块名称映射到全局路径,路径中有karma的指纹,例如:
//'。/ machine.service':'/ base / src / app / machine.service.js?f4523daf879cfb7310ef6242682ccf10b2041b3e'
var moduleName = appPath.replace(/ ^ \ / base \ / app \ /.* \ /.* \ //,'。/')。renplace(/\。js $ /,' ');
pathsMapping [moduleName] = appPath +'?'+ window .__ karma __。files [appPath]
return pathsMapping;
},{})
}
}
});
System.import('angular2 / testing')。然后(函数(测试){
返回System.import('angular2 / platform / testing / browser')。然后(函数(提供者){
testing.setBaseTestProviders(providers.TEST_BROWSER_PLATFORM_PROVIDERS,
providers.TEST_BROWSER_APPLICATION_PROVIDERS);
});
})。then(function(){
return Promise .all(
Object.keys(window .__ karma __。files)//由Karma提供的所有文件。
.filter(onlySpecFiles)
// .map(filePath2moduleName)//规范化路径到模块名。
.map(函数(moduleName){
//通过其全局模块名称加载所有spec文件(例如'base / src / app / hero.service.spec')
return System.import(moduleName);
}));
})
.then(function(){
__karma __。start();
},function (错误){
__karma __。error(error.stack || error);
});
函数filePath2moduleName(filePath){
返回filePath。
替换(/ ^ \ //,'')。 // remove / prefix
replace(/\.\w + $ /,''); //删除后缀
}
function onlyAppFiles(filePath){
return /^\/base\/app\/.*\/ 。* \ /.* \。js $ / .test(filePath)
}
仅函数SpecFiles(path){
return / _test\ 。的.js $ /测试(路径);
}
我的 karma.conf.js

module.exports = function(config){
config.set({
basePath:'',
框架:['jasmine'],

任何人都可以知道我哪里出错了吗?
您的项目结构中似乎没有 src
级别。所以你在你的 karma-test-shim.js
文件中使用它:
System.config({
packages:{
'base / app':{//< -----(而不是base / src / app)
defaultExtension:false ,
格式:'register',
map:Object.keys(window .__ karma __。files)。
filter(onlyAppFiles)。
reduce(function createPathRecords(pathsMapping,appPath) {
(...)
},{})
}
}
});
我还要将预测试
任务添加到你的 package.json
文件,用于在执行Karma之前编译你的TypeScript文件。类似的东西:
{
(...)
脚本:{
( ...)
pretest:tsc,
test:karma start karma.conf.js
}
}
I have a project that looks like:
I am trying to get Karma/Jasmine working as the test framework. I tried replicating this project: https://github.com/juliemr/ng2-test-seed, modifying it to my needs. I have a mock test in test
folder that I am trying to get to run. Though, when I try to do the npm run test
this is what I get:
I am not sure if my file paths are correct in the karma-test-shim.js
/karma.conf.js
as I'm still relatively new to working with npm/node projects.
Here is my karma-test-shim.js
(file paths are located in var moduleName
and onlyAppFiles
function):
// 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/src/app': {
defaultExtension: false,
format: 'register',
map: Object.keys(window.__karma__.files).
filter(onlyAppFiles).
reduce(function createPathRecords(pathsMapping, appPath) {
// creates local module name mapping to global path with karma's fingerprint in path, e.g.:
// './hero.service': '/base/src/app/hero.service.js?f4523daf879cfb7310ef6242682ccf10b2041b3e'
var moduleName = appPath.replace(/^\/base\/app\/.*\/.*\//, './').replace(/\.js$/, '');
pathsMapping[moduleName] = appPath + '?' + window.__karma__.files[appPath]
return pathsMapping;
}, {})
}
}
});
System.import('angular2/testing').then(function(testing) {
return System.import('angular2/platform/testing/browser').then(function(providers) {
testing.setBaseTestProviders(providers.TEST_BROWSER_PLATFORM_PROVIDERS,
providers.TEST_BROWSER_APPLICATION_PROVIDERS);
});
}).then(function() {
return Promise.all(
Object.keys(window.__karma__.files) // All files served by Karma.
.filter(onlySpecFiles)
// .map(filePath2moduleName) // Normalize paths to module names.
.map(function(moduleName) {
// loads all spec files via their global module names (e.g. 'base/src/app/hero.service.spec')
return System.import(moduleName);
}));
})
.then(function() {
__karma__.start();
}, function(error) {
__karma__.error(error.stack || error);
});
function filePath2moduleName(filePath) {
return filePath.
replace(/^\//, ''). // remove / prefix
replace(/\.\w+$/, ''); // remove suffix
}
function onlyAppFiles(filePath) {
return /^\/base\/app\/.*\/.*\/.*\.js$/.test(filePath)
}
function onlySpecFiles(path) {
return /_test\.js$/.test(path);
}
And my karma.conf.js
:
module.exports = function(config) {
config.set({
basePath: '',
frameworks: ['jasmine'],
files: [
// paths loaded by Karma

Can anyone figure out where I am going wrong?
It seems that you don't have a src
level into your project structure. So you use this into your karma-test-shim.js
file:
System.config({
packages: {
'base/app': { // <----- (instead of base/src/app)
defaultExtension: false,
format: 'register',
map: Object.keys(window.__karma__.files).
filter(onlyAppFiles).
reduce(function createPathRecords(pathsMapping, appPath) {
(...)
}, {})
}
}
});
I would also add a pretest
task into your package.json
file to compile your TypeScript files before executing Karma. Something like that:
{
(...)
scripts: {
(...)
"pretest": "tsc",
"test": "karma start karma.conf.js"
}
}
