TestCafe can't compile TypeScript test files if tsconfig.json contains the `moduleResolution` option

What is your Test Scenario?

I upgraded from v1.2.1 to v1.3.0 in one of my TypeScript projects. Since the update I get compiler errors as you can see below. I already saw in the docs that I cannot override the module and target options. But these are defined in my existing tsconfig.json and I don’t want to change them.

What is the Current behavior?

TestCafe complains with

You cannot override the "target" compiler option in the TypeScript configuration file.
You cannot override the "module" compiler option in the TypeScript configuration file.
ERROR Cannot prepare tests due to an error.

Error: Debug Failure. Unexpected moduleResolution: node

What is the Expected behavior?

Should not fail with errors as before with v1.2.1

What is your web application and your TestCafe test code?

This is my tsconfig.json:

{
  "compilerOptions": {
    "target": "es2018",
    "module": "esnext",
    "outDir": "target",
    "moduleResolution": "node",
    "jsx": "react",
    "noEmitOnError": true,
    "importHelpers": true,
    "sourceMap": true,
    "declaration": true,
    "strict": true,
    "noUnusedLocals": true,
    "noUnusedParameters": true,
    "noImplicitReturns": true,
    "noFallthroughCasesInSwitch": true,
    "incremental": true,
    "allowSyntheticDefaultImports": true,
    "esModuleInterop": true,
    "plugins": [{ "name": "typescript-tslint-plugin" }],
    "typeRoots": ["./typings", "./node_modules/@types"]
  },
  "include": ["src/**/*", "test/**/*"],
  "exclude": ["node_modules"]
}

Steps to Reproduce:

1. Go to my website …
2. Execute this command…
3. See the error…

Your Environment details:

• testcafe version: 1.3.0
• node.js version: 12.4.0
• command-line arguments:
• browser name and version:
• platform and version:
• other:

But I think that we should disable the possibility of overriding

But does that mean we can’t use TestCafe out of the box (without a dedicated tsconfig.testcafe.json) as long as my project tsconfig.json defines the moduleResolution property?
