javascript – 如何从Code Coverage Istanbul Reporter中排除模拟文件
作者:互联网
我有一个关于Istanbul Reporter的问题,用于在我的角度6应用程序中报告我的单元测试覆盖率.
我的问题是:当覆盖范围呈现时,我看到测试文件列表中的模拟,显然模拟没有经过测试,这给了我错误的覆盖统计数据.
这是我的同事设置的karma.conf文件,我想知道你是否知道如何排除那些模拟文件.
module.exports = function (config) {
config.set({
basePath: '',
frameworks: ['jasmine', '@angular-devkit/build-angular'],
plugins: [
require('karma-jasmine'),
require('karma-chrome-launcher'),
require('karma-jasmine-html-reporter'),
require('karma-coverage-istanbul-reporter'),
require('@angular-devkit/build-angular/plugins/karma')
],
client:{
clearContext: false // leave Jasmine Spec Runner output visible in browser
},
coverageIstanbulReporter: {
dir: require('path').join(__dirname, 'coverage'), reports: [ 'html', 'lcovonly' ],
fixWebpackSourcePaths: true
},
angularCli: {
environment: 'local'
},
reporters: ['progress', 'kjhtml'],
port: 9876,
colors: true,
logLevel: config.LOG_INFO,
autoWatch: true,
browsers: ['Chrome'],
singleRun: false
});
};
我在StackOverflow上看到它可以通过在tsconfig.spec.json中添加一个exclude来完成,但即使重新运行代码覆盖,它仍然包含它们.
{
"extends": "../../tsconfig.json",
"compilerOptions": {
"outDir": "../../out-tsc/spec",
"module": "commonjs",
"types": [
"jasmine",
"node"
],
"typeRoots": [ "../node_modules/@types" ]
},
"files": [
"src/test.ts",
"src/polyfills.ts"
],
"include": [
"**/*.spec.ts",
"**/*.d.ts"
],
"exclude": [
"/**/*mock*.ts"
]
}
我的模拟文件位于每个模块/功能的tests / mocks文件夹中,称为“mock-whatevertheymock.ts”
运行它的命令是
test:wc-dogs": "ng test --project=wc-dogs--code-coverage
感谢您的帮助
解决方法:
谢谢大家,解决方法是在angular.json中添加codeCoverageExclude选项
"test": {
"builder": "@angular-devkit/build-angular:karma",
"options": {
"main": "projects/wc-claims/src/test.ts",
"polyfills": "projects/wc-claims/src/polyfills.ts",
"tsConfig": "projects/wc-claims/tsconfig.spec.json",
"karmaConfig": "projects/wc-claims/karma.conf.js",
"styles": [
"projects/wc-claims/src/styles.css"
],
"scripts": [],
"assets": [
"projects/wc-claims/src/favicon.ico",
"projects/wc-claims/src/assets"
],
"codeCoverageExclude": [
"/**/*mock*.ts"
]
}
},
