开玩笑地忽略文件模式以进行代码覆盖 [英] Jest ignore file pattern for code coverage

问题描述

在经过Jest测试的项目中，我有*.entity.ts个文件.我不希望这些文件包含在覆盖测试中.

In my Jest tested project I have *.entity.ts files. I don't want these files to be included in my coverage test.

根据 https://facebook上的文档.github.io/jest/docs/en/configuration.html#coveragepathignorepatterns-array-string 中有一个coveragePathIgnorePatterns设置，您可以在package.json

According to the documentation at https://facebook.github.io/jest/docs/en/configuration.html#coveragepathignorepatterns-array-string there is a coveragePathIgnorePatterns setting which you can use in the package.json

我已经尝试过正则表达式和文件模式，但是没有一个会忽略最终报告中的*.entity.ts文件.

I've tried regex and file patterns but none of these just ignores the *.entity.ts files in the final report.

例如，当我添加"coveragePathIgnorePatterns": ["common"]时，我的测试将不再运行.

When I add for example "coveragePathIgnorePatterns": ["common"] my tests won't even run anymore.

是否有任何关于如何使Jest跳过覆盖测试中的*.entity.ts的想法?

Any thoughts on how I can make Jest skip the *.entity.ts in the coverage tests?

package.json中的我的Jest部分如下:

My Jest section in the package.json looks like:

{
    "moduleFileExtensions": [
        "js",
        "json",
        "ts"
    ],
    "rootDir": "src",
    "testRegex": ".spec.ts$",
    "transform": {
        "^.+\\.(t|j)s$": "ts-jest"
    },
    "coverageDirectory": "../coverage"
}

推荐答案

我使用外部JSON文件保存Jest配置，并使用npm从package.json运行它:jest --config jest.config.json --no-cache

I use an external JSON file to hold my Jest configuration and run it from my package.json using npm: jest --config jest.config.json --no-cache

jest.config.json

jest.config.json

{
    "collectCoverage": true,
    "collectCoverageFrom": [
        "src/**/*.ts"
    ],
    "coveragePathIgnorePatterns": [
        "node_modules",
        "test-config",
        "interfaces",
        "jestGlobalMocks.ts",
        ".module.ts",
        "<rootDir>/src/app/main.ts",
        ".mock.ts"
    ],
    "coverageDirectory": "<rootDir>/coverage/",
    "coverageThreshold": {
        "global": {
            "branches": 20,
            "functions": 30,
            "lines": 50,
            "statements": 50
        }
    },
    "mapCoverage": true,
    "preset": "jest-preset-angular",
    "setupTestFrameworkScriptFile": "<rootDir>/src/setupJest.ts",

    "transformIgnorePatterns": [
        "<rootDir>/node_modules/(?!@ionic-native|@ionic|@ngrx|angular2-ui-switch|angularfire2|jest-cli)"
    ],
    "verbose": false
}

我的报道不包括"coveragePathIgnorePatterns"中列出的文件.也许源行"/src/app/main.ts"就是您需要的条目.

My coverage does not include the files listed in the "coveragePathIgnorePatterns". Maybe the source line "/src/app/main.ts" is the entry you need.
