istanbul

I am trying to decide on a JS test code coverage tool but cannot see clearly the differences between them. The top hits in Google are blanket.js, istanbul-js and JSCover. Can anyone offer any information on the key differences between them and advantages/disadvantages? Are there any other useful ones out there? After some trying around i clearly find istanbul the most convenient tool to bring coverage analysis to a node-js project. its installed with npm install it sets up its behavior via the .istanbul.yml gets invoked by its own executable it provides multiple report formats such as clover,

I am trying to get the Code Coverage for my typescript Code in karma framework using Istanbul in karma.conf typescript files are included and by karma typescript-preprocessor we able to do unit testing and code coverage of the typescript code but Code coverage report come for trans piled JavaScript code How can I get the coverage report for typescript code? Here is my karma.conf file. module.exports = function(config) { config.set({ // base path, that will be used to resolve files and exclude basePath: '', // frameworks to use frameworks: ['jasmine'], preprocessors: { 'src/**/*.ts': [

I have a Jenkins project to do SonarQube analysis of my NodeJS project. I added istanbul as a dependency to my project's package.json . In the Jenkins build configuration, first I run a shell script: cd ./project-name npm install node_modules/.bin/istanbul cover ./node_modules/.bin/_mocha path-to-unit-tests node_modules/.bin/istanbul report cobertura cd .. This installs the dependencies, runs the tests and generates a code coverage report and generates a cobertura-coverage.xml file. After the shell script, I run a Invoke Standalone SonarQube Analysis with the following properties for code

I'm testing out a simple application (from the Mocha tutorial code here https://marcofranssen.nl/using-mocha-chai-sinon-to-test-node-js/ ) to try to get Istanbul to work. My problem is that Istanbul works fine to give me a coverage summary, but then spits out an error for some reason and I'm not sure why. My tests all pass so they're hopefully not the problem. Here is how I run Istanbul: $ istanbul cover test.js ============================================================================= Writing coverage object [C:\Users\path\test\coverage\coverage.json] Writing coverage reports at [C:\Users

背景 随着业务增长, 随之而来的前端需求激增, 如何在有限的时间内保证前端代码的质量. 通过测试同学单方面的保障, 还是免不了前端线上问题, 存在回归不到位或者测试遗漏的地方, 同时测试质量的高低没有客观数据可量化.<br> 通过单测方法补充, 可以提前发现一部分问题, 减少问题解决的成本, 但是由于业务形态的原因, 需求变更频繁, 功能迭代快, 补充和维护单测的成本比较高, 在业务方的大部分前端工程中暂时没有单测方法, 因此开发在自测时, 感知比较薄弱, 无量化数据, 在项目提测前也没有统一指标可以把关, 测试对开发的自测状况也不了解;<br> 同时前端缺少像jacoco这样的集成测试覆盖率统计框架, 无法通过集成测试收集覆盖率, 对于测试阶段的质量仍然没有数据量化 结合上面说的几点, 我们提出了前端集成测试覆盖率统计工具的需要, 以此来提升开发自测质量以及项目提测质量, 同时帮助补充回归不到位或测试遗漏的场景, 提升上线质量. 技术选型 首先, 覆盖率收集的前提, 需要完成代码插桩工作, 插桩方法来自于两个开源覆盖率统计框架, istanbul.js以及istanbul-middleware (以下称im) , 提供了若干个插桩方法, 而im其实也是在istanbul.js的基础上做了封装, 能力来自于istanbul-lib-instrument 所有的插桩方法,

In Jest, is there any way to ignore code for test coverage? I tried using /* istanbul ignore next */ But it doesn't seem to work. ilyar It works. (function(global) { var defineAsGlobal = true; /* istanbul ignore next */ if(typeof exports === 'object') { module.exports = lib; defineAsGlobal = false; } /* istanbul ignore next */ if(typeof modules === 'object' && typeof modules.define === 'function') { modules.define('lib', function(provide) { provide(lib); }); defineAsGlobal = false; } /* istanbul ignore next */ if(typeof define === 'function') { define(function(require, exports, module) {

We are trying to make a SonarQube code coverage report for our angular application. We have used Karma to generate a code coverage report and import it into SonarQube analyzer. The SonarQube already has C# coverage for our project, now we want to add JavaScript code coverage as well. Teamcity calls, Karma and it creates a code coverage and put the lcov file and report files into src\Planning.Spa\Coverage\report folder.
