Description

After updating Realm to 1.27.0, any realm import inside my *.test.ts or inside my application code it throws an Error, that it cannot find module 'realm'.

But if i start my react native (expo) application, everything works fine.

My Jest Config:

import { pathsToModuleNameMapper } from 'ts-jest';
// In the following statement, replace `./tsconfig` with the path to your `tsconfig` file
// which contains the path mapping (ie the `compilerOptions.paths` option):
import type { JestConfigWithTsJest } from 'ts-jest';

import { compilerOptions } from './tsconfig.json';

const jestConfig: JestConfigWithTsJest = {
    preset: 'jest-expo', // Use the react native preset instead of jest-expo
    transform: {
        '^.+\\.[jt]sx?$': 'babel-jest',
    },
    /** Either execute tests from global __tests__ directory or those matched by file name with *.test.ts(x) pattern */
    testMatch: ['**/src/__tests__/**/*.[jt]s?(x)', '**/?(*.)+(test).[jt]s?(x)'],
    coverageReporters: ['cobertura', 'lcov'],
    collectCoverage: true,
    testResultsProcessor: 'jest-sonar-reporter',
    coveragePathIgnorePatterns: [
        'node_modules',
        'jest.setup.tsx',
        '<rootDir>/src/__tests__',
    ],
    setupFilesAfterEnv: [
        './node_modules/react-native-gesture-handler/jestSetup.js',
        './node_modules/jest-expo/src/preset/setup.js',
        './src/__tests__/jest.setup.tsx',
    ],
    testPathIgnorePatterns: [
        '<rootDir>/node_modules/',
        '<rootDir>/src/__tests__/jest.setup.tsx',
        '<rootDir>/src/__tests__/__mocks__/',
        '<rootDir>/src/__tests__/__mockdata__/',
        '<rootDir>/src/__tests__/__utils__/',
    ],
    testEnvironment: 'jsdom',
    roots: ['<rootDir>'],
    modulePaths: [compilerOptions.baseUrl], // <-- This will be set to 'baseUrl' value
    moduleNameMapper: {
        ...pathsToModuleNameMapper(compilerOptions.paths /* , { prefix: '<rootDir>/' } */),
        '\\.svg': '<rootDir>/src/__tests__/__mocks__/svgMock.ts',
    },
    moduleDirectories: ['node_modules', 'src/__tests__/__utils__', '__dirname'],
    verbose: true,
};

export default jestConfig;

Babel Config:

module.exports = function (api) {
    api.cache(true);
    return {
        presets: ['@babel/preset-typescript', 'babel-preset-expo'],
        plugins: [
            ['@babel/plugin-proposal-decorators', { legacy: true }],
        ],
    };
};
