LGTM if CI is green and stress tests have expected results

I get this message from CI

You can ignore this. Yellow CI means that something that we know is broken (or flaky) has failed again. If you're interested the tracking issue is #13343

On a different subject, question to @nodejs/testing if test-http-server-keep-alive-timeout.js and test-https-server-keep-alive-timeout.js are similar enough, should we parametrize and merge?

realwakka · 2017-06-04T17:11:26Z

Sure, I can fix it that simplify http and https. And I'll work it soon.

Trott · 2017-06-05T00:45:33Z

Nit on the commit message, but it can be handled by whoever lands this: I'd say refactor instead of import. The test isn't being imported, really.

realwakka · 2017-06-07T00:33:51Z

I have some problem with parameterizing and merging. I made some js file for sharing function for http and https. there is dilemma about linter. new js file ( test-server-keep-alive-timeout.js ) requires common and http/https requires new js source. linter says every js file needs to require mandatory common module. because of this, I inserted some source in http/https but it's gonna be unused variable!
is there other way to use new js file for function?

You could put a comment suppressing the linter, but if it's not a trivial change, IMHO you can skip the merge.

Parameterize and merge two similar test sources. Http's test has function and http's test require it.

lpinca · 2017-06-08T16:10:37Z

Despite @refack suggestion I think keeping the tests separate is better.

Advantages:

easier to read and understand.
easier to modify them independently if necessary.
no need to use workarounds for our test harness.

Disadvantages:

code duplication.

lpinca · 2017-06-08T16:11:50Z

Anyway this needs to be re-reviewed.

refack · 2017-06-08T17:15:27Z

test/parallel/test-http-server-keep-alive-timeout.js


-const tests = [];
+  if (isHttps) {


Since this is the only if id do this separately for each file, and pass all the objects as args.

refack

Still 👍
Requesting some changes for readability

refack · 2017-06-08T17:15:50Z

test/parallel/test-http-server-keep-alive-timeout.js

-    const options = {
-      port: server.address().port,
-      allowHalfOpen: true
+    const fs = require('fs');


then move all the require to the top

refack · 2017-06-08T17:20:12Z

test/parallel/test-http-server-keep-alive-timeout.js

-const assert = require('assert');
-const http = require('http');
-const net = require('net');
+module.exports.testServerKeepAliveTimeout = function(common, isHttps) {


As per https://github.com/nodejs/node/blob/master/doc/guides/writing-tests.md
put const common = require('../common'); as L2 then a blank line and then a comment

// Testing http[s] server keepalive semantics. // Reusing tests with test-https-server-keep-alive-timeout.js // Ref: https://github.com/nodejs/node/pull/13448

This is a test file, not a library file. It shouldn't be exporting. -100 to exporting something to another test file from it.

One more for the pro-merge:

Assert that keepalive semantics are the same for http and https

refack · 2017-06-08T17:28:54Z

test/parallel/test-https-server-keep-alive-timeout.js

-    });
-  }));
-});
+const timeoutTest = require('./test-http-server-keep-alive-timeout');


IMHO this could be moved to other file as well, and delete this one.
So other file will be:

const setup http, net, createOptions, serverOptions, createServer; testServerKeepAliveTimeout(http, net, createOptions, serverOptions, createServer) const https, tls, createOptions, serverOptions, createServer; testServerKeepAliveTimeout(https, tls, createOptions, serverOptions, createServer)

This has the benefit of eliminating node startup time (that could be ~2s)

Trott

Well, it was OK. This refactoring to remove code duplication is not something I'm excited about for the reasons @lpinca outlines. This PR should have landed when it was getting approvals and it worked and it was a clear improvement over what was there. The additional refactoring to remove code duplication could have been a separate PR. @realwakka if you want to revert it to what you had, that would be great by me. You can open a separate PR for the refactoring to remove code duplication if interested.

Trott · 2017-06-08T20:54:07Z

test/parallel/test-https-server-keep-alive-timeout.js

-    });
-  }));
-});
+const timeoutTest = require('./test-http-server-keep-alive-timeout');


Please do not use require() to load an adjacent test file as a module

aqrln · 2017-06-08T23:43:42Z

+1 to what @lpinca and @Trott said. I don't think that code duplication is a problem for tests. To the contrary, the testing code should be maximally dumb and straightforward, or otherwise you'd need to test your tests ;)

aqrln · 2017-06-08T23:44:42Z

test/parallel/test-http-server-keep-alive-timeout.js

+
+    createOptions = function(server) {
+      return {
+ port: server.address().port,


FWIW, the indentation is off here.

This reverts commit f0ef3e6.

aqrln · 2017-06-09T00:26:09Z

@realwakka I've noticed you reverted the last commit, thanks.

Still LGTM.

code reverted, dismissing my request for changes
