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,但它找不到这些文件中的函数。
从我到目前为止所读到的内容,我认为在传递给伊斯坦布尔进行报道之前,文件没有被正确浏览,但不可否认我是新手,所以我希望有一些建议。
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'],

'client/scripts/*.js'
],
// list of files to exclude

],
// preprocess matching files before serving them to the browser

},

outputDir: '', // results will be saved as $outputDir/$browserName.xml
outputFile: undefined, // if included, results will be saved as $outputDir/$browserName/$outputFile

useBrowserName: true // add browser name to report and classes names
},
// Configure coverage reporter
coverageReporter: {

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,
})
}
这确实产生了一个报告,但这显示了100%,并且在common.js文件中找到的唯一行是:
require("C:\\Source\\ProjectName\\client\\scripts\\common.js");
我试图将Browerify-Istanbul添加到混合中,在Karma.conf的顶部添加一个需求,在browserify部分添加一个额外的转换
bundle.transform(istanbul)
然而,这只会让我的测试失败并抛出几个错误:

我错过了什么,或是以错误的方式解决这个问题?

我有完全相同的问题。对我有用的是删除"覆盖"从预处理器部分和使用browserify-istanbul。此外,您希望将browserify-istanbul配置为忽略您的测试文件。
因此,您的预处理器应该类似于(已删除' coverage'):
// 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']
},
您的browserify配置应该类似于:
browserify: {
configure: function (bundle) {
bundle.transform('reactify', { extensions: ['.jsx'] });
bundle.transform(require('browserify-istanbul')({
ignore: ['**/test_unit/**']
}));
}
},
希望有所帮助

对我而言,解决方案是:
将* .js文件的值数组中的'coverage'从预处理器索引删除到karma.conf
希望有所帮助
