Dojo Integration Test Skill

This skill sets up a complete local Dojo development stack and enables integration testing of smart contracts.

Required Input

Before running this skill, you MUST know the contract location on local disk:

• Contract Path: Absolute or relative path to the Dojo project directory (e.g.,

  ./worlds/dojo-starter

  )

This path should contain:

• Scarb.toml

  - Cairo project configuration

• src/

  - Cairo source files

• dojo_dev.toml

  - Dojo development configuration

Prerequisites Check

Before starting, verify the following:

1. Required asdf plugins: sozo, katana, torii, scarb

   asdf current sozo && asdf current katana && asdf current torii && asdf current scarb
   

2. Project files:

   • .tool-versions

     - defines tool versions

   • Scarb.toml

     - Cairo project configuration

   • dojo_dev.toml

     - Dojo development configuration

3. Available ports:

   • 5050 (Katana RPC)
   • 8080 (Torii HTTP)
   • 50051 (Torii gRPC)

   Check with:

   lsof -i :5050 -i :8080 -i :50051

Contract Information Extraction

Extract contract information from manifest and config files:

# Get world address (after migration)
jq -r '.world.address' manifest_dev.json

# List all contracts
jq -r '.contracts[].tag' manifest_dev.json

# List all models
jq -r '.models[].tag' manifest_dev.json

# Get RPC URL from dojo_dev.toml
grep rpc_url dojo_dev.toml

Infrastructure Startup Sequence

Step 1: Start Katana

katana --dev --dev.no-fee &

Wait for:

curl -s localhost:5050 | jq .

Step 2: Build and Migrate Contracts

sozo build && sozo migrate

Extract world address after migration:

WORLD_ADDRESS=$(jq -r '.world.address' manifest_dev.json)
echo "World address: $WORLD_ADDRESS"

Step 3: Start Torii

Default mode (asdf-installed torii):

torii --world $WORLD_ADDRESS --http.cors_origins "*" &

From source mode (when user requests "build from source", "use source", or "compile torii"):

Ask the user for the torii source directory path, then run:

cd <TORII_SOURCE_PATH> && cargo run --release --bin torii -- --world $WORLD_ADDRESS --http.cors_origins "*" &

Wait for health check:

curl -s localhost:8080/health

Contract Interaction Commands

Execute Contract Functions

Before executing contract functions, you need to discover available contracts, their functions, and understand the calldata format.

Step 1: Discover Available Contracts

# List all deployed contracts
jq -r '.contracts[].tag' manifest_dev.json

# Get detailed contract info including systems/functions
jq '.contracts[] | {tag, systems}' manifest_dev.json

Step 2: Find Available Functions

# List all functions for a specific contract
jq '.contracts[] | select(.tag == "dojo_starter-actions") | .systems' manifest_dev.json

Step 3: Read Cairo Source for Function Signatures

To understand function parameters, read the Cairo source files:

# Find system implementations
ls src/systems/

# Read the actions contract to see function signatures
cat src/systems/actions.cairo

Example: In

actions.cairo

fn spawn(ref self: ContractState) { ... }
fn move(ref self: ContractState, direction: Direction) { ... }

Step 4: Find Enum/Type Definitions for Calldata

For enum types like

Direction

# Read model definitions
cat src/models.cairo

Example Direction enum:

#[derive(Copy, Drop, Serde, PartialEq, Introspect)]
pub enum Direction {
    None,   // 0
    Left,   // 1
    Right,  // 2
    Up,     // 3
    Down,   // 4
}

Step 5: Execute Functions

# Format: sozo execute <namespace>-<contract> <function> [calldata...]

# No arguments
sozo execute dojo_starter-actions spawn

# With enum argument (use numeric value)
sozo execute dojo_starter-actions move -c 1  # Direction::Left
sozo execute dojo_starter-actions move -c 3  # Direction::Up

# With multiple arguments
sozo execute dojo_starter-actions some_func -c 0x123,42,1

Inspect World State

sozo inspect

Query via GraphQL (Torii)

curl -X POST http://localhost:8080/graphql \
  -H "Content-Type: application/json" \
  -d '{"query": "{ dojoStarterMovesModels { edges { node { player remaining } } } }"}'

Subscribe to Entities (gRPC)

grpcurl -plaintext \
  -d '{"clause":{"keys":{"keys":[],"pattern_matching":1,"models":["dojo_starter-Position"]}}}' \
  localhost:50051 world.World/SubscribeEntities

Verification Patterns

Health Checks

curl -s localhost:5050

curl -s localhost:8080/health

grpcurl -plaintext localhost:50051 list

Verify Entity State

After executing a contract function, verify state changes:

# Execute spawn
sozo execute dojo_starter-actions spawn

# Check Position model via GraphQL
curl -X POST http://localhost:8080/graphql \
  -H "Content-Type: application/json" \
  -d '{"query": "{ dojoStarterPositionModels { edges { node { player vec { x y } } } } }"}'

Cleanup

Kill Background Processes

# Kill katana
pkill -f "katana"

# Kill torii
pkill -f "torii"

Clean Database Files (optional)

rm -rf torii.db* katana.db*

Quick Start Workflow

Complete workflow for testing:

# 1. Check prerequisites
asdf current sozo katana torii scarb

# 2. Start katana
katana --dev --dev.no-fee &
sleep 2

# 3. Build and migrate
sozo build && sozo migrate

# 4. Extract world address
WORLD_ADDRESS=$(jq -r '.world.address' manifest_dev.json)

# 5. Start torii
torii --world $WORLD_ADDRESS --http.cors_origins "*" &
sleep 3

# 6. Verify services
curl -s localhost:5050 > /dev/null && echo "Katana: OK"
curl -s localhost:8080/health > /dev/null && echo "Torii: OK"

# 7. Execute test transaction
sozo execute dojo_starter-actions spawn

# 8. Verify state change
curl -s -X POST http://localhost:8080/graphql \
  -H "Content-Type: application/json" \
  -d '{"query": "{ dojoStarterPositionModels { edges { node { player vec { x y } } } } }"}'

Troubleshooting

Port Already in Use

# Find process using port
lsof -i :5050
lsof -i :8080

# Kill by PID
kill -9 <PID>

Migration Fails

# Clean build artifacts
sozo clean
sozo build
sozo migrate

Torii Not Indexing

Ensure world address matches:

# Verify world address in manifest
jq -r '.world.address' manifest_dev.json

# Restart torii with correct address
pkill -f torii
torii --world $(jq -r '.world.address' manifest_dev.json) --http.cors_origins "*" &
