TypeScript checker performance cost

[ThierryRietveld]

When this plugin is enabled it comes with a big performance hit. This is a known issue for the Stryker team. I can't assign people to this issue, but a colleague and I are working on a solution.

If you are running jest with ts-jest, did you tried transpileOnly property in your jest tsconfig ?

tsconfig.jest.json

{
    "extends": "tsconfig.json",
    "compilerOptions": {
        ...
    },
    "ts-node": {
        "transpileOnly": true
      },
}
