给出以下jest测试（testfile-test.js）：
jest.dontMock('../testfile');
describe('testfile', function() {
it('can write', function() {
var fs = require('fs');
var testfile = require('../testfile');
testfile.write("something");
expect(fs.writeFile).toBeCalled();
});
});
在package.json中也有以下jest配置：
"jest": {
"testPathDirs": ["web"],
"testDirectoryName": "__tests__",
"unmockedModulePathPatterns": [
"tty",
"net",
"debug",
"send",
"mime"
],
"testPathIgnorePatterns": [
"/node_modules/",
"/dist/",
"/.tmp/",
"/web/bower_components/",
"/web/components/"
]
}
但运行此测试会产生以下结果：
Using Jest CLI v0.2.2

如果我删除＆＃34; var testfile = require（＆＃39; ../ testfile＆＃39;）;＆＃34;从测试它工作正常。为什么send / mime模块没有被模拟？
