This check is now redundant, you may safely remove it.

assert(http.METHODS.includes('DELETE'));
assert(http.METHODS.includes('GET'));
assert(http.METHODS.includes('HEAD'));
assert(http.METHODS.includes('POST'));
assert(http.METHODS.includes('PUT'));
assert.deepStrictEqual(util._extend([], http.METHODS), http.METHODS.sort());
assert.equal(methods.length, http.METHODS.length);

This is covered by the next assert statement, so I'd say this is redundant. By the way, please use strictEqual() instead of equal() in such cases :)

assert.deepStrictEqual(methods.sort(), http.METHODS.sort());

Previously this test asserted that the http.METHODS array is alphabetically sorted. So as not to change the test expectations, you should either drop .sort() from http.METHODS, or drop both .sort()s and make the array in this test sorted beforehand. I'd prefer the latter way, but one might find the former one conveying the intention more clearly, so I'm fine with both.

Aside from that, can you please swap the order of arguments here? According to the function's signature, first argument should be an actual value and second one an expected value.
