问题描述
我正在使用mocha/supertest/should.js测试我的Rest Service
I am using mocha/supertest/should.js to test my 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 .自v0.11以来,这似乎是最快,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.
因此您的代码将变为tmpBuf.equals(testBuf)
