run

Runs a set of functions on an interaction

This is a utility function for testing that builds and resolves an interaction with the provided builder functions. It automatically adds a reference block and then resolves the interaction for testing purposes.

Import

You can import the entire package and access the function:

_10

import * as sdk from "@onflow/sdk"

_10

_10

sdk.run(fns)

Or import directly the specific function:

_10

import { run } from "@onflow/sdk"

_10

_10

run(fns)

Usage

_28

import { run } from "@onflow/sdk"

_28

import * as fcl from "@onflow/fcl";

_28

_28

// Test a simple script interaction

_28

const result = await run([

_28

fcl.script`

_28

access(all) fun main(): Int {

_28

return 42

_28

}

_28

`

_28

]);

_28

_28

console.log(result.cadence); // The Cadence script

_28

console.log(result.tag); // "SCRIPT"

_28

_28

// Test a transaction with arguments

_28

const txResult = await run([

_28

fcl.transaction`

_28

transaction(amount: UFix64) {

_28

prepare(account: AuthAccount) {
