typescript-stryker: Compilation fails, but tsc through npm does not

part of stryker.conf

    config.set({
        files: [

            { pattern: 'src/**/app.component.ts', mutated: true, included: false },

            { pattern: 'src/**/*.{ts,scss,html,json,png}', included: false, mutated: false },
            { pattern: 'src/app/testing/**/*.ts', included: true, mutated: false },
        ],

        transpilers: ['typescript'],
        tsconfigFile: 'tsconfig.json',
        reporter: ['progress', 'html'],
        htmlReporter: {

        // maxConcurrentTestRunners: 1,
        clearTextReporter: {
            maxTestsToLog: 0
        },

When I run tsc Everything compiled ok, without errors.

When stryker run it produce a tons of errors:

core.module.ts(26,12): error TS2304: Cannot find name 'window'.
core.module.ts(30,12): error TS2304: Cannot find name 'localStorage'.
x.service.ts(35,129): error TS2339: Property 'includes' does not exist on type 'Type[]'.

In tsconfig lib dom, esnext is specified, but looks like stryker ignores it.

In trace mode, I do not see message that lib.dom.d.ts is loaded by TranspilingLanguageService Like

[DEBUG] TranspilingLanguageService - Pulling file into memory...

[nicojs]

@unlight thanks very much for testing out our new TypeScript support.

Your assumption is correct in that you should see a Pulling file into memory message. Take Stryker itself as an example:

[2017-09-25 22:48:40.943] [DEBUG] TranspilingLanguageService - Resolving lib file lib.es5.d.ts to C:\z\github\stryker-mutator\stryker\node_modules\typescript\lib\lib.es5.d.ts
[2017-09-25 22:48:40.943] [DEBUG] TranspilingLanguageService - Pulling file into memory: lib.es5.d.ts
[2017-09-25 22:48:40.962] [DEBUG] TranspilingLanguageService - Resolving lib file lib.es2015.promise.d.ts to C:\z\github\stryker-mutator\stryker\node_modules\typescript\lib\lib.es2015.promise.d.ts
[2017-09-25 22:48:40.963] [DEBUG] TranspilingLanguageService - Pulling file into memory: lib.es2015.promise.d.ts

Do you see any lib files at all?

Could you run in debug once more and look at the top for "[DEBUG] Stryker - Using config:". There you should also see your typescript config (read using the stryker-typescript ConfigEditor plugin). Could you verify that the lib file is displayed there?

Finally: what versions are you using for typescript and stryker?

[unlight]

Versions:

stryker@0.10.3
stryker-typescript@0.0.2
typescript@2.5.2

I see only this typescript related definition files:

[DEBUG] TranspilingLanguageService - Pulling file into memory: C:/xxx/node_modules/typescript/lib/lib.es2015.d.ts
[DEBUG] TranspilingLanguageService - Pulling file into memory: C:/xxx/node_modules/typescript/lib/lib.es2015.core.d.ts
[DEBUG] TranspilingLanguageService - Pulling file into memory: C:/xxx/node_modules/typescript/lib/lib.es2015.collection.d.ts
[DEBUG] TranspilingLanguageService - Pulling file into memory: C:/xxx/node_modules/typescript/lib/lib.es2015.generator.d.ts
[DEBUG] TranspilingLanguageService - Pulling file into memory: C:/xxx/node_modules/typescript/lib/lib.es2015.promise.d.ts
[DEBUG] TranspilingLanguageService - Pulling file into memory: C:/xxx/node_modules/typescript/lib/lib.es2015.iterable.d.ts
[DEBUG] TranspilingLanguageService - Pulling file into memory: C:/xxx/node_modules/typescript/lib/lib.es2015.symbol.d.ts
[DEBUG] TranspilingLanguageService - Pulling file into memory: C:/xxx/node_modules/typescript/lib/lib.es2015.proxy.d.ts
[DEBUG] TranspilingLanguageService - Pulling file into memory: C:/xxx/node_modules/typescript/lib/lib.es2015.reflect.d.ts
[DEBUG] TranspilingLanguageService - Pulling file into memory: C:/xxx/node_modules/typescript/lib/lib.es2015.symbol.wellknown.d.ts
[DEBUG] TranspilingLanguageService - Pulling file into memory: C:/xxx/node_modules/typescript/lib/lib.es5.d.ts

No esnext which is specified in tsconfig. But es2015 was specified explicitly in one of the my spec file by triple comment reference

/// <reference path="../../../node_modules/typescript/lib/lib.es2015.d.ts" />

This pushed me to an idea, and finally I was able to solve it by creating empty ts file with content:

/// <reference path="../node_modules/typescript/lib/lib.dom.d.ts" />
/// <reference path="../node_modules/typescript/lib/lib.esnext.d.ts" />

But initial run still fails for me, but for another reason.

[nicojs]

@unlight ok, so the finger clearly points to Stryker not loading lib files correctly. I tried to reproduce the problem in this small sample: https://github.com/nicojs/stryker-typescript-issue394

I did come across an other bug #396 , but other than that the lib files seems to be loaded fine.

Could you try out this small sample and try to reproduce the problem there?

[unlight]

I've just tried and issue is not reproducible there, esnext definition is loading ok. I will continue investigation in my project.

[unlight]

Figure out the problem. Need remove all 'path' triple reference <reference path="node_modules/typescript/lib/lib.es2015.d.ts" due to <reference no-default-lib="true"/> it prevents loading what is defined in tsconfig.lib

[nicojs]

@unlight ok, cool you found the problem. Just to be clear, you had <reference no-default-lib="true"/> somewhere in your code? If so, how could typescript itself compile?

Are you now able to run stryker on typescript code? Or is there some other issue your running into?

[unlight]

I had several references to 'lib.es2015' in my code. 'lib.es2015' contains 'reference no-default-lib' directive. I suspect that it was the reason.
