Karma js似乎无法提供我项目中的任何图像。我目前的业力配置如下：
module.exports = function (config) {
config.set({
/**
* These are the files required to run the tests.
*
* The `Function.prototype.bind` polyfill is required by PhantomJS
* because it uses an older version of JavaScript.
*/
files: [
{pattern: "src/assets/images/*.png", watched: false, included: false, served: true},
'./Unit_Tests/polyfill.js',
'./Unit_Tests/main.js'
],
proxies: {
"/img/": "/src/assets/images/"
},
/**
* The actual tests are preprocessed by the karma-webpack plugin, so that
* their source can be properly transpiled.
*/
preprocessors: {
'./Unit_Tests/main.js': ['webpack'],
'**/*.less': ['less']
},
/**
* We want to run the tests using the PhantomJS headless browser.
* This is especially useful for continuous integration.
*/
browsers: ['PhantomJS'],
/**
* Use Mocha as the test framework, Sinon for mocking, and
* Chai for assertions.
*/
frameworks: ['mocha', 'sinon-chai'],
/**
* After running the tests, return the results and generate a
* code coverage report.
*/
reporters: ['progress', 'coverage'],
/**
* When generating a code coverage report, use `lcov` format and
* place the result in coverage/lcov.info
*
* This file will be sent to Coveralls by the `coveralls` npm script.
*/
coverageReporter: {
dir: 'coverage/',
reporters: [
{type: 'lcovonly', subdir: '.', file: 'lcov.info'},
{type: 'html', subdir: 'html'}
]
},
/**
* The configuration for the karma-webpack plugin.
*
* This is very similar to the main webpack.local.config.js, with the
* exception of specifying an istanbul-transformer post loader so
* that we can generate an accurate code coverage report.
*/
webpack: {
module: {
loaders: [
{test: /\.jsx?$/, exclude: /node_modules/, loader: "babel-loader?stage=0"},
{test: /\.less$/, loader: "style!css!less"}
],
postLoaders: [{
test: /\.jsx?$/,
exclude: /(test|node_modules)\//,
loader: 'istanbul-instrumenter'
}]
},
resolve: {
extensions: ['', '.js', '.jsx', '.css', '.less']
}
},
/**
* Configuration option to turn off verbose logging of webpack compilation.
*/
webpackMiddleware: {
noInfo: true
},
/**
* Once the mocha test suite returns, we want to exit from the test runner as well.
*/
singleRun: true,
/**
* List of plugins
*/
plugins: [
'karma-mocha',
'karma-webpack',
'karma-coverage',
'karma-sinon-chai',
'karma-phantomjs-launcher'
],
});
}
我总是收到这个错误：
Error: Cannot find module "../assets/images/downloadios.png"
如果我使用此设置运行它：
module.exports = function (config) {
config.set({
/**
* These are the files required to run the tests.
*
* The `Function.prototype.bind` polyfill is required by PhantomJS
* because it uses an older version of JavaScript.

'./Unit_Tests/main.js'
],

* their source can be properly transpiled.

'**/*.less': ['less']
},

我收到此错误：
SyntaxError: Parse error

我现在已经过了几个小时了，似乎无法找到让这件事情快乐的组合。我不明白我做错了什么我看过所有可以找到的业力js例子，似乎没什么用。
答案 0 :(得分：2)
因此，当我将以下内容添加到我的karma.config.js时，它将清除此问题
webpack: {
module: {
loaders: [
{test: /\.jsx?$/, exclude: /node_modules/, loader: "babel-loader?stage=0"},
{test: /\.less$/, loader: "style!css!less"},
{test: /\.(png|jpg)$/, loader: 'url-loader?limit=8192'}
],
postLoaders: [{
test: /\.jsx?$/,
exclude: /(test|node_modules)\//,
loader: 'istanbul-instrumenter'
}]
},
resolve: {
extensions: ['', '.js', '.jsx', '.css', '.less']
}
},
{test：/.( png | .jpg）$ /，loader：'url-loader？limit = 8192'}
