Function TestUsageHasTokens

pkg/runtime/cost_test.go:15–23

TestUsageHasTokens covers the helper that suppresses the missing-price warning for empty/no-op turns. The per-message cost arithmetic and its nil/unpriced branches are exercised by TestComputeMessageCost in after_llm_call_test.go, which shares the same computeMessageCost source.

// nil/unpriced branches are exercised by TestComputeMessageCost in
// after_llm_call_test.go, which shares the same computeMessageCost source.
