test: fix flaky test-http-client-timeout-option-with-agent #22403

Trott · 2018-08-19T16:18:47Z

First commit:

There is no guarantee that a timeout won't be delayed considerably due
to unrelated activity on the host. Instead of checking that the timeout
happens within a certain tolerance, simply check that it did not happen
too soon.

Second commit:

test-http-client-timeout-option-with-agent no longer checks that the
timeout happens within a certain tolerance so it can be moved to the
parallel test suite.

Checklist

make -j4 test (UNIX), or vcbuild test (Windows) passes

test/parallel/test-http-client-timeout-option-with-agent.js

-    // some number of milliseconds, so test it in second units.
-    assert.strictEqual(duration / 1000 | 0, HTTP_CLIENT_TIMEOUT / 1000);
+    // some number of milliseconds.
+    assert.ok(duration >= HTTP_CLIENT_TIMEOUT,


I think a timeout can expire a little sooner than the specified delay so I'm not sure this resolves the flakiness.

I think a timeout can expire a little sooner than the specified delay so I'm not sure this resolves the flakiness.

AFAIK it can't, at least not at the millisecond resolution.

It seems this has been fixed in #20555 as per
#10154 (comment).

+    // some number of milliseconds.
+    assert.ok(duration >= HTTP_CLIENT_TIMEOUT,
+              `${duration} < ${HTTP_CLIENT_TIMEOUT}`);


Maybe actual duration ${duration}ms was less than expected ${HTTP_CLIENT_TIMEOUT}ms.

I think git no like the change-after-rename:
