问题：开玩笑无法解析相对路径

从'command.test.ts'中找不到模块'../../ common / utility / json.utility'

1 |从'../../common/utility/json.utility'导入{JsonUtility}; | ^

在Resolver.resolveModule（node_modules / jest-resolve / build / index.js：259：17）在对象。（test / command / poll / command.test.ts：1：1）

我的配置：

** jest.config.js：**详细信息

module.exports = {
    verbose: true,
    transform: {
        '^.+\\.tsx?$': 'ts-jest'
    },
    testEnvironment: 'node',
    testRegex: '(/test/.*|(\\.|/)(test|spec))(\\.it)?\\.(jsx?|tsx?)$',
    testPathIgnorePatterns: ['/coverage', '/lib', '/test/fixture'],
    testResultsProcessor: './node_modules/jest-junit-reporter',
    moduleFileExtensions: ['ts', 'tsx', 'js', 'jsx', 'json', 'node'],
    coverageThreshold: {
        global: {
            branches: 15, // 80

        }
    },
    collectCoverageFrom: ['src/**/*.ts', '!src/index.ts'],
    coverageReporters: ['json-summary', 'text', 'lcov']
};

您可能想开玩笑地配置模块路径：https://jestjs.io/docs/en/configuration#modulepaths-arraystring

类似的东西：

module.exports = {
    verbose: true,
    transform: {
        '^.+\\.tsx?$': 'ts-jest'
    },
    testEnvironment: 'node',
    testRegex: '(/test/.*|(\\.|/)(test|spec))(\\.it)?\\.(jsx?|tsx?)$',
    testPathIgnorePatterns: ['/coverage', '/lib', '/test/fixture'],
    testResultsProcessor: './node_modules/jest-junit-reporter',
    moduleFileExtensions: ['ts', 'tsx', 'js', 'jsx', 'json', 'node'],
    coverageThreshold: {
        global: {
            branches: 15, // 80
            functions: 15, // 80
            lines: 15, // 80
            statements: 0 // 20
        }
    },
    collectCoverageFrom: ['src/**/*.ts', '!src/index.ts'],
    coverageReporters: ['json-summary', 'text', 'lcov'],
    modulePaths: [ // Add your paths here
        "<rootDir>/src/"
    ],
};
