Writing Your Own Tests

Back to Testing Contracts

Adding a Compilation Test

1. Create a new Solidity file in examples/ or examples/new/.
2. The E2E test suite automatically picks up files in these directories.
3. Run cargo test --test e2e_compilation_tests to verify.

Adding a Smoke Test

1. Create a new script in examples/ following the pattern of existing scripts.
2. The script should:
   • Create a temporary directory and clean up on exit
   • Resolve neo-solc and neoxp binaries
   • Write a test contract inline
   • Compile, deploy, invoke, and validate
3. Add a Make target in the Makefile.
4. Add the target to test-deploy-smoke-full dependencies.

Adding a Unit Test

Add #[test] functions in the relevant module or create a new test file in tests/:

#[test]
fn test_my_feature() {
    let source = r#"
        // SPDX-License-Identifier: MIT
        pragma solidity ^0.8.20;
        contract Test {
            function foo() public pure returns (uint256) {
                return 42;
            }
        }
    "#;
    // Use the compiler API to compile and validate
    // ...
}
