mock mate, easy to mock http
request, fs
access and so on.
Mock伴侣,单元测试必备。
jscoverage: 100%
$ npm install mm
var mm = require('mm');
var http = require('http');
var mockURL = '/foo';
var mockResData = 'mock data';
var mockResHeaders = { server: 'mock server' };
mm.http.request(mockURL, mockResData, mockResHeaders);
mm.https.request(mockURL, mockResData, mockResHeaders);
// http
http.get({
path: '/foo'
}, function (res) {
console.log(res.headers); // should be mock headers
var body = '';
res.on('data', function (chunk) {
body += chunk.toString();
});
res.on('end', function () {
console.log(body); // should equal 'mock data'
});
});
// https
https.get({
path: '/foo'
}, function (res) {
console.log(res.headers); // should be mock headers
var body = '';
res.on('data', function (chunk) {
body += chunk.toString();
});
res.on('end', function () {
console.log(body); // should equal 'mock data'
});
});
var mm = require('mm');
var http = require('http');
var mockURL = '/foo';
var reqError = null;
var resError = 'mock res error';
mm.http.requestError(mockURL, reqError, resError);
var req = http.get({
path: '/foo'
}, function (res) {
console.log(res.statusCode, res.headers); // 200 but never emit `end` event
res.on('end', fucntion () {
console.log('never show this message');
});
});
req.on('error', function (err) {
console.log(err); // should return mock err: err.name === 'MockHttpResponseError'
}
var mm = require('mm');
var fs = require('fs');
mm.error(fs, 'readFile', 'mock fs.readFile return error');
fs.readFile('/etc/hosts', 'utf8', function (err, content) {
console.log(err); // should return mock err: err.name === 'MockError'
mm.restore(); // remove all mock effects.
fs.readFile('/etc/hosts', 'utf8', function (err, content) {
console.log(err); // should return null
console.log(content); // should show the host list
});
});
mm.data(fs, 'readFile', new Buffer('some content'));
mm.empty(mysql, 'query');
mm.datas(urllib, 'request', new Buffer('data'), { headers: { foo: 'bar' } });
use mm
just like muk
var fs = require('fs');
var mm = require('mm');
mm(fs, 'readFile', function (path, callback) {
process.nextTick(callback.bind(null, null, 'file contents here'));
});
