问题描述
我正在使用 mocha/supertest/should.js
来测试 REST 服务
I am using mocha/supertest/should.js
to test REST Service
GET/files/<hash>
将文件作为流返回.
如何在 should.js
中断言文件内容相同?
How can I assert in should.js
that file contents are the same?
it('should return file as stream', function (done) {
var writeStream = fs.createWriteStream('test/fixtures/tmp.json');
var req = api.get('/files/676dfg1430af3595');
req.on('end', function(){
var tmpBuf = fs.readFileSync('test/fixtures/tmp.json');
var testBuf = fs.readFileSync('test/fixtures/test.json');
// How to assert with should.js file contents are the same (tmpBuf == testBuf )
// ...
done();
});
});
推荐答案
令人惊讶的是,没有人建议 Buffer.equals.从 v0.11 开始,这似乎是最快和最简单的方法.
Surprisingly, no one has suggested Buffer.equals. That seems to be the fastest and simplest approach and has been around since v0.11.
所以你的代码会变成 tmpBuf.equals(testBuf)
