Istanbul上的JSX测试的代码覆盖率 [英] Code coverage on JSX tests with Istanbul
问题描述
我正在尝试使用我的代码来获得一定的覆盖范围并运行，但是有些东西滑入了我的手指。
I am trying to instrument my code to get some coverage up and running, but something is slipping through my fingers.
我启动了 istanbul 与：
node_modules/.bin/istanbul cover ./node_modules/mocha/bin/_mocha -- -u exports -R spec
和我的 mocha.opts 看起来像这样：
app/assets/javascripts/components/**/*-mocha.jsx
--compilers jsx:mocha/compiler.js
一切似乎都运行良好（测试运行，至少），但是我唯一了解的是用于将JSX编译为JavaScript的文件（用于 compiler.js
Everything seems to run fine (the tests run, at least), but the only coverage that I get is on the files used to compile the JSX to JavaScript (used in compiler.js
compiler.js 100%
jsx-stub-transform.js 65%
非常有用...
有什么想法吗？
推荐答案
我正在使用摩卡和 Babel 6 isparta a>如下：
I am using mocha and isparta directly with Babel 6 as follows:
BABEL_ENV=test babel-node node_modules/isparta/bin/isparta cover _mocha
.babelrc
.babelrc
{
"plugins": [
"add-module-exports",
"transform-decorators-legacy",
"transform-runtime"
],
"presets": [
"es2015",
"react",
"stage-0"
],
"env": {
"test": {
"plugins": [
"rewire"
]
}
}
}
test / mocha.opts
test/mocha.opts
--compilers js:babel-core/register
--require test/init.js
src/**/*_test.js*
test.init.js
test.init.js
'use strict';
require('mock-require')('clappr');
require('testdom')('<html><body></body></html>', {
React: 'react',
localStorage: 'localStorage'
});
.istanbul.yml
.istanbul.yml
instrumentation:
root: src
excludes: ['*_test.js']

.JSX文件的注释
我将所有我的.JSX文件转换为.JS，原因如下：
A note on .JSX files
I renamed all of my .JSX files to .JS, and here's why:
- 我使用 codecov 用于托管覆盖率报告。这暴露了一个事实，尽管
coverage / lcov-report / index.html显示了正确的覆盖率，但.JSX文件缺少JSON覆盖率文件中的某些内容。我从来没有想过。据我所知，这是isparta或istanbul中的错误。我还尝试了istanbul@1.0.0-alpha.2，发现它也存在相同的问题。 - 用于推荐命名文件的反应.JSX，有利于转换实用程序和编辑器。这不再是建议。据我所知，这不再重要。
- I use codecov for hosted coverage reporting. This exposed the fact that while
coverage/lcov-report/index.htmlshowed the correct coverages, something in the JSON coverage files is missing for .JSX files. I was never able to figure it out. As far as I can tell, it's a bug in isparta or istanbul. I also triedistanbul@1.0.0-alpha.2and found it had the same issue. - React used to recommend naming files .JSX for the benefit of transform utilites and editors. This is no longer a recommendation. As far as I can tell, it just doesn't matter anymore.
自从切换到.JS后，我再也没有看到
Since switching to .JS, I haven't seen any issues with tools including Atom and IntelliJ.
如果不想重命名文件，可以在上面的示例中添加以下内容：
If you don't want to rename your files, you can add the following to my examples from above:
- 在脚本中，在
isparta封面之后，添加-include \ src / ** / * _ test.jsx\。 - 至
.istanbul.yml，添加
- In the script, after
isparta cover, add--include \"src/**/*_test.jsx\". - To
.istanbul.yml, add
extensions:
- .js
- .jsx
