在node.js中捕获console.log吗?
问题描述：
有没有一种方法可以在node.js中捕获由console.log(...)引起的最终控制台输出，以防止在单元测试模块时记录终端?
Is there a way that I can catch eventual console output caused by console.log(...) within node.js to prevent cloggering the terminal whilst unit testing a module?
谢谢
答
module.js:
module.js:
module.exports = function() {
console.log("foo");
}
程序:
console.log = function() {};
mod = require("./module");
mod();
// Look ma no output!
显然，您可以根据需要收集日志消息，以备以后使用:
Obviously you can collect the log messages for later if you wish:
var log = [];
console.log = function() {
log.push([].slice.call(arguments));
};
