我正在努力设置 Expresso 并运行一些测试。我跟随了一个关于节点 tuts 的教程,并运行了 4 个测试并通过了。现在,我试图在运行测试时显示代码覆盖率输出,就像文档显示的那样。但是,我有点迷路了。

我的超级基础学习示例测试位于名为 test 的文件夹中的 test.js 文件中:

var Account = require('../lib/account');

require('should');

module.exports = {
    "initial balance should be 0" : function(){
        var account = Account.create();
        account.should.have.property('balance');
        account.balance.should.be.eql(0);
    },

    "crediting account should increase the balance" : function(){
        var account = Account.create();
        account.credit(10);
        account.balance.should.be.eql(10);
    },

    "debiting account should decrease the balance" : function(){
        var account = Account.create();
        account.debit(5);
        account.balance.should.be.eql(-5);
    },

    "transferring from account a to b b should decrease from a and increase b": function(){
        var accountA = Account.create();
        var accountB = Account.create();
        accountA.credit(100);
        accountA.transfer(accountB, 25);
        accountA.balance.should.be.eql(75);
        accountB.balance.should.be.eql(25);
    }
}

代码本身在 lib/account.js 中:

var Account = function(){
    this.balance = 0;
}

module.exports.create = function(){
    return new Account();
}

Account.prototype.credit = function(amt){
    this.balance += amt;
}

Account.prototype.debit = function(amt){
    this.balance -= amt;
}

Account.prototype.transfer = function(acct, amt){
    this.debit(amt);
    acct.credit(amt);
}

Account.prototype.empty = function(acct){
    this.debit(this.balance);
}

当我从命令行运行 expresso 时,我得到:

$ expresso

    100% 4 tests

同样,如果我expresso使用-c标志或各种其他选项运行,我会得到相同的输出。我想获得文档中显示的代码覆盖率输出。我也运行了命令$ node-jscoverage lib lib-cov,现在 lib-cov 文件夹中有东西..

我错过了什么?

到目前为止我发现的最佳结果是在测试运行时编辑路径:

这是 run_tests.sh

#! /bin/bash

rm -Rf ./app-cov
node_modules/expresso/deps/jscoverage/node-jscoverage app/ app-cov
NODE_PATH=$NODE_PATH:/usr/local/lib/node:/usr/local/lib/node_modules:./mmf_node_modules:./app-cov node_modules/expresso/bin/expresso -c
