【问题描述】:
我正在尝试为我的 Karma 测试添加代码覆盖率,但是虽然它找到了我正在测试的正确 JS 文件,但它没有在这些文件中找到函数。
从我目前所读的内容来看,我认为这与文件在传递到伊斯坦布尔进行报道之前没有被正确浏览有关,但我承认我是新手,所以我希望得到一些建议。
这是我的 JS 文件(common.js):
var applicationSettings = require('./settings');
var common = {
getAjaxBaseUrl: function () {
var strVirtualDirectory = applicationSettings.VirtualDirectory;
if (strVirtualDirectory.length > 1) {
if (!strVirtualDirectory.startsWith("/")) {
strVirtualDirectory = "/" + strVirtualDirectory;
}
}
return strVirtualDirectory;
}
}
module.exports = common;
这是我写的测试:
it('Client - Should get correct AjaxBaseUrl with /', function () {
var clientSettings = require('./../client/scripts/settings');
var clientCommon = require('./../client/scripts/common');
clientSettings.VirtualDirectory = '/VD';
expect(clientCommon.getAjaxBaseUrl()).to.equal('/VD');
});
it('Client - Should get correct AjaxBaseUrl without /', function () {
var clientSettings = require('./../client/scripts/settings');
var clientCommon = require('./../client/scripts/common');
clientSettings.VirtualDirectory = 'VD';
expect(clientCommon.getAjaxBaseUrl()).to.equal('/VD');
});
我的 Karma.conf 如下:
// Karma configuration
// Generated on Mon Jan 11 2016 09:43:00 GMT+0000 (GMT Standard Time)
module.exports = function (config) {
config.set({
// base path that will be used to resolve all patterns (eg. files, exclude)
basePath: '',
// frameworks to use
// available frameworks: https://npmjs.org/browse/keyword/karma-adapter
frameworks: ['phantomjs-shim', 'browserify', 'mocha'],
// list of files / patterns to load in the browser
files: [
'https://code.jquery.com/jquery-2.2.0.min.js',
'http://cdn.kendostatic.com/2015.3.1111/js/kendo.all.min.js',
'test_unit/*Spec.js',
'client/scripts/*.js'
],
// list of files to exclude
exclude: [
],
// preprocess matching files before serving them to the browser
// available preprocessors: https://npmjs.org/browse/keyword/karma-preprocessor
preprocessors: {
'test_unit/*Spec.js': ['browserify'],
'client/scripts/*.js': ['browserify', 'coverage']
},
// test results reporter to use
// possible values: 'dots', 'progress'
// available reporters: https://npmjs.org/browse/keyword/karma-reporter
reporters: ['progress', 'coverage', 'junit'],
// Configure jUnit reporter
junitReporter: {
outputDir: '', // results will be saved as $outputDir/$browserName.xml
outputFile: undefined, // if included, results will be saved as $outputDir/$browserName/$outputFile
suite: '', // suite will become the package name attribute in xml testsuite element
useBrowserName: true // add browser name to report and classes names
},
// Configure coverage reporter
coverageReporter: {
type: 'html',
dir: 'test_coverage',
subdir: '.',
file: 'coverage.htm'
},
// web server port
port: 9876,
// enable / disable colors in the output (reporters and logs)
colors: true,
// level of logging
// possible values: config.LOG_DISABLE || config.LOG_ERROR || config.LOG_WARN || config.LOG_INFO || config.LOG_DEBUG
logLevel: config.LOG_INFO,
// enable / disable watching file and executing tests whenever any file changes
autoWatch: false,
browserify: {
configure: function (bundle) {
bundle.transform('reactify', { extensions: ['.jsx'] });
}
},
// Continuous Integration mode
// if true, Karma captures browsers, runs the tests and exits
singleRun: true,
// Concurrency level
// how many browser should be started simultaneous
concurrency: Infinity,
})
}
这确实会生成一份报告,但显示为 100%,并且在 common.js 文件中找到的唯一行是:
require("C:\\Source\\ProjectName\\client\\scripts\\common.js");
我尝试将 Browerify-Istanbul 添加到组合中,方法是在 Karma.conf 的顶部添加对它的要求,在 browserify 部分中添加一个额外的转换
bundle.transform(istanbul)
但这只会让我的测试失败并抛出几个错误:

是我遗漏了什么,还是以错误的方式解决了这个问题?
【问题讨论】:
-
您解决了这个问题吗?看来您正在让 istanbul 正常运行?
-
嗨,请看标记的答案,这就是我所做的,它似乎有效!
