Jest ignore file pattern for code coverage
提问by Bas van Dijk
In my Jest tested project I have *.entity.tsfiles. I don't want these files to be included in my coverage test.
在我的 Jest 测试项目中，我有*.entity.ts文件。我不希望这些文件包含在我的覆盖率测试中。
According to the documentation at https://facebook.github.io/jest/docs/en/configuration.html#coveragepathignorepatterns-array-stringthere is a coveragePathIgnorePatternssetting which you can use in the package.json
根据在文档https://facebook.github.io/jest/docs/en/configuration.html#coveragepathignorepatterns-array-string有一个coveragePathIgnorePatterns，你可以在使用设置package.json
I've tried regex and file patterns but none of these just ignores the *.entity.tsfiles in the final report.
我试过正则表达式和文件模式，但这些都没有忽略*.entity.ts最终报告中的文件。
When I add for example "coveragePathIgnorePatterns": ["common"]my tests won't even run anymore.
例如，当我添加时，"coveragePathIgnorePatterns": ["common"]我的测试甚至不再运行。
Any thoughts on how I can make Jest skip the *.entity.tsin the coverage tests?
关于如何让 Jest 跳过*.entity.ts覆盖测试的任何想法？
My Jest section in the package.json looks like:
我在 package.json 中的 Jest 部分如下所示：
{
"moduleFileExtensions": [
"js",
"json",
"ts"
],
"rootDir": "src",
"testRegex": ".spec.ts$",
"transform": {
"^.+\.(t|j)s$": "ts-jest"
},
"coverageDirectory": "../coverage"
}

I use an external JSON file to hold my Jest configuration and run it from my package.jsonusing npm: jest --config jest.config.json --no-cache
我使用外部 JSON 文件来保存我的 Jest 配置并从我package.json使用的 npm运行它： 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
}
My coverage does not include the files listed in the "coveragePathIgnorePatterns". Maybe the source line "/src/app/main.ts" is the entry you need.
我的覆盖范围不包括“coveragePathIgnorePatterns”中列出的文件。也许源代码行“/src/app/main.ts”是您需要的条目。

You can add a ! mark in collectCoverageFrom parameter to exclude it from counting. Here any file inside a subfolder of src dir
您可以添加一个！在 collectCoverageFrom 参数中标记以将其从计数中排除。这里是 src 目录的子文件夹中的任何文件
collectCoverage: true,
collectCoverageFrom: ['src/**/*.ts','!src/*/filesToExclude.ts']
