How Contracts Are Collected

snforge supports two mechanisms for collecting contracts used in tests.

By default, optimized collection mechanism is used.
If running snforge test with --no-optimization flag, the old collection mechanism is used.

Differences Between Collection Mechanisms

Using contracts from `/tests`	❌	✅
Using contracts from modules marked with `#[cfg(test)]`	❌	✅
Using contracts from dependencies	✅	✅
Contracts more closely resemble ones from real network	✅	❌
Less compilation steps required (faster compilation)	❌	✅
Additional compilation step required (`scarb build`)	✅	❌
