錯誤nodejs單元測試使用茉莉，karma：require沒有定義

Question

我使用jasmine進行node.js單元測試，使用karma工具。

運行時出現錯誤：「require is not defined」。

我嘗試了很多東西，比如使用karma-browserify，requirejs但沒有一個工作。

我嘗試了這個link中的所有建議的解決方案，但他們都沒有爲我工作。

這是我karma.config.js

module.exports = function(config) {

    basePath: '',

這個錯誤可能是由你的src/**/*.js和src/server.js文件require電話引起的。

您在瀏覽器中加載這些文件：

files: [ 
     'src/**/*.js', 
     'src/server.js', 
     'test/*.js' 
    ], 

沒有與broserify預處理：

preprocessors: { 
    'test/*.js': [ 'browserify' ] 
},
