调研方向

Start in internal/e2e/tmux_test.go at skipSetup around line 247, then read the setupIsUp predicate around line 273 and the tagged TestHomeRestoredNavigationNoModel/180 subtest. Run the stated e2e test and trace the helper's scripted transitions. Done means the delayed transition repeatedly leaves the test on Home, the unit test proves no Escape is sent after Home appears, and the timing assumption is recorded in invalidates.

描述

area:tests bug hygiene sev:papercut

Seen on dev@debffabf6. Surfaced while verifying #1389; not introduced by it.

What happened

TestHomeRestoredNavigationNoModel/180 failed once under load when skipSetup sent another Escape after setup had already disappeared. That Escape landed on Home and closed it. The helper checks the screen after each press but waits 900 ms before checking; a transition within that interval can put the next key on a different page. This is one observed flake, not a measured failure rate.

Replication

Deterministic (no model). In the tagged e2e rig, script setup to disappear immediately after an Escape while the next captured frame still contains setup text briefly. Call skipSetup; its loop can issue another Escape, which Home interprets as close. Assert the final page is Home. The real subtest is go test -tags e2e -run 'TestHomeRestoredNavigationNoModel/180' ./internal/e2e/.

Where

internal/e2e/tmux_test.go:247 at dev@debffabf6, skipSetup, sends up to six Escapes separated by a fixed sleep; its screen predicate is setupIsUp at :273.

The fix

Wait for a confirmed transition to the target page after each setup action, and stop sending Escape once that transition is observed.

Acceptance

  • e2e: the 180-column tagged subtest repeatedly ends on Home under a delayed setup transition.
  • Unit: a scripted transition test proves the helper sends no Escape after Home appears.
  • Record the former timing assumption in the test change entry's invalidates.
