This allows to detect on runtime that the code is executed via jest with TS support enabled via ts-jest. Works via setting environment variable TS_JEST=1.

Closes #2716

Summary

I am author of MikroORM. It allows to discover entities either via references (entities: [User]) or via paths (entities: ['./entities']). To use the folder based discovery, I need to operate on the TS files when running via ts-node or ts-jest, as I am attaching some properties to the entity prototype and therefore need to work with TS file if that is what will be later used on runtime (in other words, if ts-node/ts-jest is used, I need to discover TS files from src, otherwise JS files from dist).

To deal with this, I have two different config options for entity paths, one for JS files, one for TS files. If I am able to detect typescript support (e.g. ts-node) I am using the TS one.

While there are several ways to detect if we are under ts-node environment (e.g. using !!process[Symbol.for('ts-node.register.instance')]), I failed to find one to detect if we are running via jest with ts-jest preset.

Test plan

As this only sets env var, it should be safe. I failed to come up with a way to test it actually works from the runtime, happy to hear suggestions. I did verify the change does what it should in my project by adding the line to node_modules.

Does this PR introduce a breaking change?

#### BREAKING CHANGES

-   By default, `ts-jest` will use `sourceMap` option from your `tsconfig`. If users want to have sourcemap on, they need to set `sourceMap: true` in `tsconfig`.
-   follow Jest support Node engines ([#&#8203;2478](https://github.com/kulshekhar/ts-jest/pull/2478)) ([1fecf7f](https://github.com/kulshekhar/ts-jest/commit/1fecf7ff92a5f1a0cc6ea1d27026f9f54a3d5ead))

-   `ts-jest` custom AST transformer function signature has changed to

<!---->

    import type { TsCompilerInstance } from 'ts-jest/dist/types'

    export function factory(compilerInstance: TsCompilerInstance) {
       //...
    }

-   One is currently using `pathRegex` should use `exclude` with `glob` patterns.
-   If one currently relies on type check for `js` files, please set `checkJs: true` in your tsconfig.
-   Now both `isolatedModules: true` and `isolatedModule: false` codes are in one single class `TsCompiler` which is an instance created in `TsJestCompiler` based on config option `compiler` with value `typescript` or `ttypescript`.
-   **config:** `packageJson` config option is not used in internal `ts-jest` so this option is now removed.
-   **config:** One is defining ast transformers in `jest.config.js`/`package.json` should change to

<!---->

    // jest.config.js
    module.exports = {
       //...
       globals: {
          'ts-jest': {
             astTransformers: {
               before: ['your_before_transformer_path'],
               after: ['your_after_transformer_path'],
               afterDeclarations: ['your_afterDeclarations_transformer_path'],
             }
          }
       }
    }

or

    // package.json
    {
      "jest": {
         "globals": {
            "ts-jest": {
               "astTransformers": {
                  "before": ["your_before_transformer_path"],
                  "after": ["your_after_transformer_path"],
                  "afterDeclarations": ["your_afterDeclarations_transformer_path"]
               }
            }
         }
      }
    }

-   One currently refers type in `jest.config.js`

<!---->

    /** @&#8203;typedef {import('ts-jest')} */
    module.exports = {
      //...
    }

should change to

    /** @&#8203;typedef {import('ts-jest/dist/types')} */
    module.exports = {
      //...
    }

-   Remove possibilities to import `mocked`, `createJestPreset`, `pathsToModuleNameMapper` from package entry. One should change to

<!---->

    import { mocked, createJestPreset, pathsToModuleNameMapper } from 'ts-jest/utils'

-   **config:** One currently uses `tsConfig` should change to `tsconfig` in your `jest.config.js` or `package.json`.
