[Bug]: Cause ts error in jest.config.ts when import 'ts-jest'
See original GitHub issueVersion
29.0.1
Steps to reproduce
Here’s my code in jest.config.ts
import type {Config} from 'jest';
import {pathsToModuleNameMapper} from 'ts-jest';
import {compilerOptions} from './tsconfig.json';
const jestConfig: Config = {
globals: {
aaa: true
},
moduleNameMapper: pathsToModuleNameMapper(compilerOptions.paths, {prefix: '<rootDir>/'})
};
export default jestConfig;
Then the type declare in ts-jest causes the type of globals error: Property ‘‘ts-jest’’ is missing in type ‘’{ aaa: true; }‘’ but required in type ‘ConfigGlobals’.ts(2741) types.d.ts(10, 13): ‘‘ts-jest’’ is declared here.
declare module '@jest/types' {
namespace Config {
interface ConfigGlobals {
'ts-jest': TsJestGlobalOptions;
}
}
}
Expected behavior
There shouldn’t be the type error when globals doesn’t contain ‘ts-jest’ since the ts-jest config has been moved to transform.
Actual behavior
The ts type error occurs: Property ‘‘ts-jest’’ is missing in type ‘xxx’(what you write in globals) but required in type ‘ConfigGlobals’.ts(2741) types.d.ts(10, 13): ‘‘ts-jest’’ is declared here.
Debug log
Error: Jest: Failed to parse the TypeScript config file xxxxx/jest.config.ts TSError: ⨯ Unable to compile TypeScript: jest.config.ts:13:3 - error TS2741: Property ‘‘ts-jest’’ is missing in type '{ aaa: true; } but required in type ‘ConfigGlobals’.

Yes:) PR is welcome to fix it
Yes, so maybe I can expect a new pkg version to solve this issue?
