Wildcard for test files about ionic-boilerplate

[marcoturi]

Hi @superkew and thank you for opening an issue. Actually you can't import files in es6 modules syntax using wildcards. If you want to achieve this result you should build a bundle task to run before "npm run test" that bundle all spec files.
Ionic team is working on an a specific task in ionic app script for unit tests and e2e test based on angular cli.

It's a pity we can't use the normal karma imports for wildcards, but good to hear that ionic will be creating some tooling for us :)

@superkew have a look at following gist to achieve such glob support and still use rollup.

There is one problem with such solution tough - you'll have to somehow init test environment (as in current shim). Doing so in every test will throw an error as you can only do so once per test session. I ended up creating singleton for test environment initialization which based on static flag executes following:
TestBed.initTestEnvironment(BrowserDynamicTestingModule, platformBrowserDynamicTesting());

just run:
npm run test:watch

And now all your spec file are watched and loaded in karma-shim automatically.

Thank you!

Hey @marcoturi and @superkew . I submitted another approach to do this. The karma-shim.ts is not changed with the watch. I created a file that generate a index.ts with import statements. So, the karma-shim.ts contains only a simple import "../src".

With this, run npm test and the index.ts file will be created on pretest package.json script.

Please, see my PR !1 and check which the better approach to a standard structure :)
