Question

我有一个基于快速的restful应用程序，我决定使用supertest进行测试。这是我第一次使用supertest进行测试，我很困惑。其中一条路线是：

binary_crossentropy

返回版本：

/api/version

哪种方法正常，当我在'http://localhost:9000/api/version/'看Chrome时，我看到了：

export function index(req: express.Request, res: express.Response) {
   log('index of version.controller');
   let ver = { version: version.getVersion() +  ' & textAngular: v' + textAngularVersion.getTextAngularVersion() };
   res.setHeader('Content-Type', 'application/json');
   return res.status(200).json(ver);
}

这是我的期望。如预期的那样，状态为200（如果已被Chrome缓存，则为304）。

然而，当我用mocha和supertest测试时：

{"version":"v0.00.000-38-gf395113 & textAngular: v1.5.16"}

我明白了：

describe('GET /api/version', () => {
     it('should respond with version', (done: any) => {
       request(app.server)
        .get('/api/version')
        .expect('Content-Type', 'text/html; charset=UTF-8')
        .expect(200)
        .end((err: any, res: any) => {
           if (err) {
             return done(err);
          }
          done();
        });
     });
});

除非我发表评论Error: expected 200 "OK", got 301 "Moved Permanently"。我也很惊讶我没有看到'application / json'的'Content-Type'。这是我上面提到的。

我很想知道为什么会这样？

应用程序有点大，我可以报告更多细节，但我怀疑有人理解为什么304的状态会显示出来。

如果我注释掉expect（200）并捕获响应，我看到：

expect(200) line

我有同样的问题。如果您遇到同样的问题，则只需更改

即可

.get('/api/version')

到

.get('/api/version/')

这种尾随斜线为测试带来了不同的世界。

为什么supertest（测试快递）返回的状态为301而不是200？
