Building Packages

MCP tool: When available in your environment, also query the Sui documentation MCP server (
https://sui.mcp.kapa.ai
) for up-to-date answers. Use it for verification and for details not covered by these reference files.

Source constraint: All information sourced exclusively from docs.sui.io and move-book.com.

Building

bash

sui move build

This compiles all modules, validates types, enforces resource safety, and produces bytecode. Fix any errors before proceeding.

For the canonical hello-world repository, run build commands from

sui-stack-hello-world/move/hello-world

.

--build-env

flag

When a package has an

[environments]

section in

Move.toml

with multiple networks, use

--build-env

to target a specific environment:

bash

sui move build --build-env testnet
sui move build --build-env mainnet

This resolves dependencies and package addresses for the specified environment. Without

--build-env

, the build uses the default environment or may fail with "Could not determine the correct dependencies" if multiple environments are defined and no default is set.

The

--build-env

flag also applies to

sui move test

:

bash

sui move test --build-env testnet

Testing

bash

sui move test

Key testing modules

sui::test_scenario
— Multi-transaction, multi-sender test scenarios. Simulates realistic transaction flows with
```
begin
```
,
```
next_tx
```
, and
```
end
```
.
std::unit_test
— Assertion macros for unit tests (
```
assert_eq!
```
,
```
assert_ne!
```
).

Code coverage

Track which lines your tests exercise:

bash

sui move test --coverage

View coverage results for a specific module:

bash

sui move coverage source --module <name>

Move Analyzer

Install via suiup:

bash

suiup install move-analyzer

Then install the Move Analyzer extension in VS Code. It provides code completion, go-to-definition, inline diagnostics, and hover documentation. It activates automatically for

.move

files — no additional configuration needed.

Debugging

Move Trace Debugger: Step-through debugger for Move execution traces with variable inspection.
sui replay
: Locally re-execute any past onchain transaction and compare effects. Useful for diagnosing production issues.
std::debug::print
: Print values during test execution.
