Developer Basecamp 13 – Session 5: Testing with Foundry

In Developer Basecamp 13 Session 5, we walked through writing integration tests using Foundry for the counter contract that we built in Session 4. You’ll learn how to create effective test cases, validate outcomes with assert, and verify that functions panic correctly. We also covered checking error messages, using cheatcodes for advanced testing, capturing events, and setting STRK balances.
