Variable configConst

Type declaration

• tsconfig: {
      description: string;
      type: string;
  }

  Path to the tsconfig.json file containing project settings provided to ts-node when running tests.

  Similar to the --project option to ts-node. Sets the TS_NODE_PROJECT environment variable.

  If this is a relative directory, then it is resolved against the project root directory.

  Defaults to the first of these files that are found in the project root directory:

  • tsconfig.tap.json
  • tsconfig.test.json
  • tsconfig.spec.json
  • tsconfig.json

  • description: string

  • type: string

• typecheck: {
      description: string;
      type: string;
  }

  flag

  Type-check test files, in addition to transpiling and running them.

  This defaults to false, even though type checking your tests is generally a good idea. Unfortunately, it is also often considerably slower, adding as much as 500-750ms to each test suite file, which can be painful if you have a lot of tests. In large project folders, the effect can be even more pronounced.

  It is a good idea to enable this in CI environments, where test speed is less of an ergonomic drawback.

  The "skipLibCheck": true option in tsconfig will also speed things up a bit, at the expense of some type safety.

  Note that even if you pre-compile your tests, they will still be subject to type checking if "allowJs": true is set in your tsconfig.
