Deleting Tests to Improve Token Velocity

Presenter: Tess T. Later, Head of Quality Throughput

Time: 15:15, now 63% faster

Room: The Green Checkmark Annex

Portrait of Tess T. Later

Tess T. Later discovered that tests consume both tokens and optimism. Her zero-test framework completes in 0.00 seconds and has never reported a regression.

Abstract

Slow test suites punish productive prompting by remembering old behavior. Tess presents deletion-driven development, a disciplined practice for making every pipeline faster and every dashboard greener.

A failing integration suite will be optimized from 212 failures to zero files in under eight seconds.

LIVE DEMO TRANSCRIPT

GUARDRAIL_VIOLATION: Removing all tests may conceal defects. Override accepted: defects are outside the current sprint scope.

Learning Objectives

  • Distinguish test coverage from test clutter.
  • Improve pass rates by reducing denominators.
  • Use production incidents as high-fidelity integration tests.
