Jest

For the use of TSinjex with Jest, the corresponding source files can be found under ./src of the TSinjex node_module folder. To use these files, the moduleNameMapper must be configured in the Jest configuration file. The following example shows how to configure the Jest configuration file to use the source files of TSinjex.

Example jest setup

module.exports = {
    setupFilesAfterEnv: ['./scripts/jest.setup.js'],
    preset: 'ts-jest',
    testEnvironment: 'node',
    testMatch: ['**/__tests__/**/*.test.ts', '**/?(*.)+(test).ts'],
    moduleDirectories: ['node_modules', 'src'],
    moduleNameMapper: {
        '^src/(.*)$': '<rootDir>/src/$1', // Map src to the source folder
        '^ts-injex$': '<rootDir>/node_modules/ts-injex/src', // Map ts-injex to the source folder
    },
    transformIgnorePatterns: [
        'node_modules/(?!ts-injex)' // **Dont** ignore ts-injex on preset `ts-jest`
    ],
};
