The test file here is named test-stream2-fs and it's in sequential. I think the test case added here belongs to test/parallel/test-fs-read-stream.js since it's more of a fs test, not a stream2 test. (Also I think this file can be moved to parallel? Although that should be done in another PR).

ok. I just moved the new test case to test/parallel/test-fs-read-stream.js.

const end = 3;
const r = new FSReadable(file, { end });
const w = new TestWriter();

wOfEnd.on('results', function(res) {
assert.strictEqual(wOfEnd.length, optionsEndExpectLength);
});
w.on('results', common.mustCall((res) => {
assert.strictEqual(w.length, end + 1);
}));

rOfEnd.pipe(wOfEnd);
r.pipe(w);
}
