From 8c5eb0847acb895e5499885bb4f712be90621458 Mon Sep 17 00:00:00 2001 From: DavidKoleczek <45405824+DavidKoleczek@users.noreply.github.com> Date: Mon, 24 Aug 2026 18:05:02 -0400 Subject: [PATCH 1/3] test(e2e): mirror extra repos into the DTU with --repo MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The harness could only mirror amplifier-agent, plus amplifier-core and amplifier-foundation when their working trees were dirty. A dependency whose changes needed exercising in the DTU had no way in, and a clean checkout parked on a branch was silently skipped because the criterion was working-tree dirtiness rather than "differs from upstream". `--repo [@]` on up/run/refresh mirrors any additional repo to the Gitea mirror and injects its url_rewrites rule, so the DTU resolves it from there. Three resolution cases: a local checkout with no ref uses the existing working-tree snapshot, a local checkout with a ref pushes that ref's commit, and no local checkout clones from GitHub. Rules are injected into the staged temp copy of the profile, so the checked-in profile is never mutated, and with no --repo the profile is copied byte-identically. Source repos are never mutated either: every resolve and fetch runs inside a throwaway clone. Pushes only ever target the local Gitea container. This also retires the hand-maintained "add rules here" comment and the hardcoded warning check, since redirection is now derived from what was actually mirrored. 🤖 Generated with [Amplifier](https://github.com/microsoft/amplifier) Co-Authored-By: Amplifier <240397093+microsoft-amplifier@users.noreply.github.com> --- .../digital-twin-universe/profiles/e2e.yaml | 6 +- tests/e2e/framework/cli.py | 35 +++- tests/e2e/framework/dtu.py | 136 ++++++++++++- tests/e2e/framework/dtu_manager.py | 178 ++++++++++++++++-- 4 files changed, 324 insertions(+), 31 deletions(-) diff --git a/.amplifier/digital-twin-universe/profiles/e2e.yaml b/.amplifier/digital-twin-universe/profiles/e2e.yaml index 2281bbec..a8f0eca8 100644 --- a/.amplifier/digital-twin-universe/profiles/e2e.yaml +++ b/.amplifier/digital-twin-universe/profiles/e2e.yaml @@ -47,8 +47,10 @@ url_rewrites: default_match_mode: boundary rules: - { match: github.com/microsoft/amplifier-agent, target: "${GITEA_URL}/admin/amplifier-agent" } - # Add amplifier-core / amplifier-foundation rules here to redirect them too when - # their working trees are being tested. + # This is the only STATIC rule.

That is the easy case. On a real machine that tree holds app-cli's live module clones, and "amplifier-agent leaves them strictly alone" was asserted by inspection rather than by test. The suite installs app-cli inside the DTU, primes its bundle cache so the tree holds real clones, records the state of ~/.amplifier, exercises amplifier-agent hard, records again, and asserts nothing changed. It then runs app-cli once more, which is the user-facing failure the guarantee exists to prevent. Five tests: the before/after comparison, app-cli still working afterwards, remote skill clones landing in the agent's own tree, doctor's isolation guard actually firing rather than being vacuous, and clone directories being independent storage where their names collide. The install lives in the suite's own conftest rather than the DTU profile's setup_cmds, so only this suite pays the download and a normal run of anything else is unaffected. Two notes on the assertions. The comparison uses path, size and mtime rather than content hashes, because app-cli's cache is large and a content change without a size or mtime change is not a realistic failure mode for git clones. And the isolation guard is exercised through AMPLIFIER_AGENT_FOUNDATION_HOME, not by unsetting AMPLIFIER_HOME, which the library rebinds at import so that path cannot fail from a subprocess.

Both are independent of the coexistence work. raw_capture and shadowing both hardcoded port 9098 for their own in-DTU server. raw_capture's fixture is session-scoped, so it holds the port for the whole run and its teardown does not fire until the very end. Since collection order puts it first, shadowing could never bind and test_skill_shadow_reported_http errored with "address already in use". Deterministic, not flaky: each suite passed alone and failed together, reproduced identically three times. Ports now live in one place, tests/e2e/framework/ports.py, naming each port and its owner, so a new suite cannot silently reuse one. shadowing moves to 9097. raw_capture's teardown also used a pkill pattern that could match its own argv and kill itself, orphaning the server; the bracketed-digit idiom shadowing already used is promoted into that same module and both now share it. The streaming timing assertion measured total elapsed between the first and last content frame against a 0.5s floor. That scales with how much the model chooses to say, which the test does not control, so a genuinely streamed but short response failed: six frames spanning 0.428s, an 86ms mean gap, reported as "looks buffered". It now measures the largest gap between consecutive frames. A streamed response has at least one real pause; a buffered dump has every gap at the measurement floor. That property does not depend on response length. Threshold is 50ms, roughly 6x below the slowest healthy observation (299ms) and 38x above the 1.3ms floor, chosen from measurements across repeated runs rather than intuition. Max rather than mean because a leading burst of frames is normal and drags the mean down while the max stays healthy. streaming-mode now asserts SSE structure only, expressed as a third value in the CASES table so it is visible where the cases are defined. It intermittently emits all content frames within a few milliseconds at the end of an 8-10 second turn, about 3 times in 12 observations, while streaming-plain over the same model and provider was clean in 9 of 9. The cause is not established, so the case comment records the measurements, states that no cause is known, and notes that timing coverage on the active-mode path is given up until it is understood. 🤖 Generated with [Amplifier](https://github.com/microsoft/amplifier) Co-Authored-By: Amplifier <240397093+microsoft-amplifier@users.noreply.github.com> --- tests/e2e/conftest.py | 14 ++- tests/e2e/framework/ports.py | 43 +++++++ tests/e2e/suites/raw_capture/conftest.py | 13 +- tests/e2e/suites/shadowing/conftest.py | 15 +-- tests/e2e/suites/streaming/test_streaming.py | 124 +++++++++++++++---- 5 files changed, 168 insertions(+), 41 deletions(-) create mode 100644 tests/e2e/framework/ports.py diff --git a/tests/e2e/conftest.py b/tests/e2e/conftest.py index 9e73f5eb..480e01b7 100644 --- a/tests/e2e/conftest.py +++ b/tests/e2e/conftest.py @@ -22,7 +22,7 @@ # tests/e2e/, is their shared parent). sys.path.insert(0, str(Path(__file__).resolve().parent)) -from framework import dtu, state +from framework import dtu, ports, state def pytest_configure(config: pytest.Config) -> None: @@ -59,17 +59,19 @@ def dtu_id(e2e_state: dict[str, Any]) -> str: def server(dtu_id: str) -> Generator[dict[str, str], None, None]: """Start the amplifier-agent HTTP server INSIDE the DTU once for HTTP cases. - Launches ``serve chat-completions`` bound to 0.0.0.0:9099 (so curl-from-inside - on localhost works), then polls ``/v1/models`` until it answers 200 or ~60s pass. - Yields the base_url + bearer token.

Those two states differ sharply at the max: +# - a genuinely streamed response has at least one real pause somewhere between +# consecutive frames, so its MAX gap is large; +# - an all-at-once dump writes every frame back-to-back from an already-complete +# result, so EVERY gap -- and therefore the max -- sits at the measurement floor. +# The mean conflates the two, because a *leading burst* is normal behavior: real +# streams routinely emit several frames within the first few milliseconds and then +# settle into steady pacing. One measured run had 5 frames inside the first 6ms +# followed by ~250-350ms gaps; that drags the mean down while the max stays healthy +# at 347ms. Max gap is robust to the leading burst and still catches true +# all-at-once delivery. +# +# Value picked from measurement, not intuition. Max gaps measured on healthy +# streams: 299ms / 347ms / 509ms on the HTTP mode path, 323ms on the plain HTTP +# path, 573ms on the CLI path. The slowest of those -- the value the threshold has +# to stay under -- is 299ms. The floor a buffered dump can reach is not zero but +# the cost of the per-line `date` subprocess in the timestamping pipe: the smallest +# single gap observed between two back-to-back frames was 1.3ms. +# +# 50ms therefore sits ~6x below the slowest healthy observation (299ms) and ~38x +# above the back-to-back measurement floor (1.3ms), so both a verbose and a terse +# real stream clear it comfortably while an all-at-once release still fails. +MIN_MAX_GAP_S = 0.05 # Sentinel appended by curl -w after the transfer completes, carrying the final # HTTP status and content-type on one line: "__META__\t". @@ -54,6 +87,11 @@ _CLI_CONFIG = "/root/e2e/host-config.json" # (name, body-extra merged over {model, ...}, expectation) +# +# expectation values: +# "stream" SSE structure AND timing (the max-gap assertion) +# "stream-structural" SSE structure ONLY -- no timing assertion +# "buffered" detector sanity: must NOT be an SSE stream CASES: list[tuple[str, dict, str]] = [ ( "streaming-plain", @@ -65,6 +103,25 @@ {"stream": False, "messages": [{"role": "user", "content": PROMPT}]}, "buffered", ), + # Structure only -- deliberately NOT timed. + # + # Measured: the active-mode path intermittently emits all of its content + # frames within a few milliseconds of each other at the end of an 8-10 second + # turn, seen roughly 3 times in 12 observations.
