How do I test my Sway contract?

You can test Sway contracts with the Fuels Rust SDK or TypeScript SDK. You can find examples in the official docs below:

I’ll add that there are plans to support testing contract calls from Sway’s in-language unit testing too:

github.com/FuelLabs/sway

Add support for calling into contract ABIs from unit tests

forc compiler: frontend forc-test

When unit tests are written within a contract module, it would be great if the u…ser could run the test assuming the contract is "deployed" and can be interacted with. We could either make this the default behaviour for contract unit tests, or we could add a special nested attribute like `#[test(script)]` or `#[test(with_contract)]` or similar. We could provide the contract's ID in a similar manner to how we provide contract dependency IDs. This will require a slightly more sophisticated testing setup in `forc-test`. Currently, we construct our own `fuel-vm` `Interpreter` and execute unit tests directly as if they were a script. Calling into contracts will instead require first *deploying* the contract and then interacting with the contract from a script via a client. This is an updated version of the #1832 issue, but specifically for supporting calling into contracts following landing #2985.

This is currently WIP, but is one of the Sway tooling team’s top priorities at the moment.
