PREDA Test Script Syntax
Allocate address
Description：
Generate specific number of addresses, The actual number of addresses applied for conforms to the following formula:
shard: the number of shards
n: positive integer
Command：
allocate.address [address_number]
Parameter：
- address_number: the number of addresses to be generated
Example：
allocate.address 10
Output:
12 addresses added and evenly distributed in shards
Specify address
Description：
Use the Allocated address in the test script
Command：
@address_order
@all
@random
Parameter：
- address_order：address order n, random, all, represents the number n+1th address, random address, and all addresses respectively.
Example：
// address_0 initiate a vote
Ballot.init @0 { names: ["Spring", "Yarn", "Combat"] }
// all address vote
Ballot.vote @all { proposal_index: $random(0,2)$, case_num: 1 }
// a random address vote
Ballot.vote @random { proposal_index: $random(0,2)$, case_num: 1 }
Random
Description:
The PREDA-Toolchain provides some functions related to random numbers, for example, specify random address or specify a random input parameter.
First at all, we should specify a seed for random.
Command:
random.reseed [seed]
Parameters:
- seed: the default seed is timestamp, but you can set as any value manually
Example：
// set the random seed
random.reseed 88
// specify a random address when call a contract function
Ballot.init @random { names: ["Spring", "Yarn", "Combat"] }
// specify a random input parameter between 0 and 2
Ballot.vote @0 { proposal_index: $random(0,2)$, case_num: 1 }
Set gas limit
Description：
Set the gas limit which is the maximum amount of gas that transactions in a block can consume.
Command：
chain.gaslimit [limit]
Parameters：
- limit: the limit for all transaction's gaslimit in a block
Example：
chain.gaslimit 128
Deploy smart contracts
Description：
Deploy smart contracts, multiple contracts can be deployed.
Command：
chain.deploy @address_order [contract_file] [*contract_file]
Parameters：
- contract_file: the name of the contract file, which supports multiple names to be set at the same time, with space-separated.
- address_order: the order of the address that initiated the contract deployment.
Example：
chain.deploy @0 SimpleStorage.prd
Output：
Compiling 1 contract code(s) ...
contract `SimpleStorage`: 2 function(s) with states in address scope(s)
0) SimpleStorage.increment: txn
1) SimpleStorage.decrement: txn
Linking and deploying ...
[PRD]: Successfully deployed 1 contract(s)
Set contract states
Description：
Set the state for the blockchain, which is used to initialize the contract state. Users need set all variable when set shard or global states.
Command：
- Set the global state
state.set global.contract_name { state_name:state_value }
- Set the shard state
state.set shard.contract_name @shard_order { state_name:state_value }
- Set the address state
state.set address.contract_name @address_order { state_name:state_value }
Parameters：
- contract_name: the name of the contract
- shard_order: the serial number for shard
- address_order: the serial number for address
- state_name: the name of the state to be set
- state_value: the value of the state to be set
Example：
Set the global state
state.set global.Ballot { controller:"$@0$", current_case:0, proposals:[], last_result:{topVoted:"",case:0}, shardGatherRatio:0}
Set the shard state
state.set shard.Ballot #all { votedWeights:[] }
Set the address state
state.set address.Ballot @all { weight:$random(1, 20)$, voted_case:0 }
Call a contract function
Description：
Call a contract function and generate the transaction into mempool .
Command：
// call a global function
contract_name.contract_function[*call_number] contract_params
// call a shard function
contract_name.contract_function[*call_number] #shard_order contract_params
// call a address function
contract_name.contract_function[*call_number] @address_order contract_params
Parameters：
- contract_name: the name of the contract
- contract_function: the name of the contract function
- call_number: the number of call times, which is an optional parameter
- shard_order: the serial number for shard, users can also use
#allto specify shard - address_order: the serial number for address, users can also use
@randomand@allto specify address - contract_params: contract input parameters
Example：
// call a global function
KittyBreeding.mint*3 { genes: "$bigint.random(32)$", gender: true, owner: "$@all$" }
// call a shard function
KittyBreeding.registerNewBorns #all {}
// call a address function
KittyBreeding.breed*$~count$ @random { m: $random(1, ~count-1)$, s: $random(~count+1, ~count*2-1)$, gender : false }
