@jennynju Find why your test case didn't finished before timeout. And in your screenshot, there is a "no such file" error. Please provide the detailed codes of your test case.

The failure happens when I excute npm run test and the failed test case is : 'should pass errors for a failed stream' in \unit\adapters\http.js.

 it('should pass errors for a failed stream', function (done) {
    server = http.createServer(function (req, res) {
      req.pipe(res);
    }).listen(4444, function () {
      axios.post('http://localhost:4444/',
        fs.createReadStream('/does/not/exist')
      ).then(function (res) {
        assert.fail();
      }).catch(function (err) {
        assert.equal(err.message, 'ENOENT: no such file or directory, open \'/does/not/exist\'');
        done();
      });
    });
  });

It failed at the assertion:
AssertionError [ERR_ASSERTION]: 'ENOENT: no such file or directory, open 'C:\\does\\not\\exist'' == 'ENOENT: no such file or directory, open '/does/not/exist''.

I think the reason is the NODE PATH format various in different environment. I'd prefer use the default node path for this test in order to escape from different environment factors.

@jennynju I just noticed that you are running our unit tests. In fact, the CI is passed. So there should be some problem in your local environment. The ENOENT is generated as expected. The most possible reason is that port 4444 is in use by other programs. Try to use another port.

@chinesedfan, FYI, it has nothing to do with the port.
Actually the issue is caused by the differences between OS systems. In Windows, path does use '/' as delimiter.
As a result, this unit test will only pass in linux-like OS system.

@jennynju I see. We can only check the beginning part of the error message and ignore the file path. PR welcome.

@chinesedfan , thanks for your comments.
I was thinking about using "__dirname" to construct the 'do not exist' folder to keep consistency between different OS systems. PR was submitted.
