我正在努力讓Expresso設置和一些測試運行。我跟着一個tutorial on node tuts,並有4個測試運行,並通過。現在我試圖在運行測試時看到代碼覆蓋率輸出,如docs顯示。但是,我有點失落。如何使用expresso顯示代碼覆蓋率輸出?
我超基本學習示例測試是在一個文件夾中稱爲test.js名爲test:
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);
}
}
和代碼本身是LIB/account.js:
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);
}
當我在命令行中運行快報,我得到:
$ expresso
100% 4 tests
同樣的,如果我有一個運行expresso
-c
標誌或各種其他選項,我得到相同的輸出。我想要獲得文檔中顯示的代碼覆蓋率輸出。我也運行命令$ node-jscoverage lib lib-cov
,而lib-cov文件夾現在有東西..
我在想什麼?
難道不是隻如果你的測試失敗不同的輸出? – fent 2012-01-11 21:05:13
雅,但不管測試通過,應該有額外的代碼覆蓋輸出。圖片示例:http://dl.dropbox.com/u/6396913/cov.png – hookedonwinter 2012-01-11 21:07:20
