2225 terms, tools, patterns and metrics an architect is expected to use precisely. Each one gets a short explanation of what it is, and — where it matters — what it is commonly confused with. Search filters as you type; the column headers sort.

Term	Kind	Topic	What it is
Flake Budget Flakiness Threshold, Quarantine Policy	practice	Flaky Test Management	A hard limit on test flakiness, enforced by automatic detection and quarantine with a deletion deadline - because above a small rate the suite stops being a signal and starts training the team to ignore failures.
Flake Rate Test Nondeterminism, Suite Trust Threshold, Intermittent Failure Rate	concept	Flaky Test Management	The proportion of test failures that are not caused by a real defect - a quantity with a sharp threshold, above which the suite stops being a signal and starts training the team to ignore failures.
Flaky Test	concept	Flaky Test Management	A test that passes and fails on unchanged code, destroying the signal value of the entire suite it belongs to.
Test Quarantine Flaky Test Isolation	practice	Flaky Test Management	Removing an unreliable test from the blocking suite immediately, so it stops eroding trust, while keeping it running non-blocking until it is fixed or deleted.
