// jest.config.js

const { createJestConfig } = require('@equisoft/jest-utils');
const { pathsToModuleNameMapper } = require('ts-jest');
const { compilerOptions } = require('./tsconfig.json');

const config = {
    moduleNameMapper: pathsToModuleNameMapper(compilerOptions.paths || [], { prefix: '<rootDir>/src/test' }),

    roots: [
        '<rootDir>/src/browser',
        '<rootDir>/src/test',
    ],
    setupFilesAfterEnv: [
        'jest-extended',
        './src/test/setup-tests.ts',
    ],

    collectCoverageFrom: ['<rootDir>/src/browser/**/*.{js,jsx,ts,tsx}'],

    transform: {
        '^.+.m?[t]sx?$': ['ts-jest', {
            tsconfig: 'src/test/tsconfig.json',
            babelConfig: {
                presets: [
                    ['@babel/preset-env', { targets: { node: 'current' } }],
                    '@babel/preset-react',
                ],
                plugins: [
                    '@babel/plugin-transform-react-display-name',
                    ['babel-plugin-styled-components', { fileName: false }],
                ],
            },
        },
        ],
    },
};
