Voting Dapp Bootcamp: Solana Anchor bankrun test fails with uninitialized address
A recent test case for a voting dapp on the Solana blockchain encountered an unexpected issue that caused it to fail. The code, specifically the voting_dapp.spec.ts file from the Solana Bootcamp voting program, fails to initialize an important variable.
The code:
import { AccountInfo } from '@solana/web3.js';
import { ProgramResult, pubkeyToAccount } from '@solana/angular-keygen';
import {
anchorBankrun,
createBanks,
initializeBanks,
} from './anchor-bankrun';
const crunchyAddress = 'your-crunchy-address-here'; // Replace with actual address
const crunchyCandidate = new AnchorCandidate(
{ authority: 'crunchy-authority', name: 'Crunchy Candidate' }
);
export async function anchorBankrunTest() {
const banks = await createBanks();
const accountInfo = new AccountInfo({ keyId: 'your-key-id-here' });
try {
const account = await accountInfo.loadAccount();
if (account.address) {
// Initialize Crunchy candidate
const result = await anchorBankrun(banks, account);
console.log(result.error ? 'Error:' + result.error.message : 'Success!');
} else {
// Process no initialized address
throw new Error('Crunchy address not found');
}
} catch (error) {
if (error instanceof Error && error.message.includes('initialized address')) {
throw error;
} else {
console.error(error);
}
}
}
class AnchorCandidate {
constructor({ authority, name }) {
this.authority = authority;
this.name = name;
}
async create() {
// Create new anchor candidate instance
}
}
The problem:
After reviewing the code, the initialization of crunchyAddress appears to be incomplete. The variable is declared as const crunchyAddress = 'your-crunchy-address-here';, but no attempt is made to set its value or initialize it before attempting to access it.
Therefore, when the test tries to create an anchor candidate using new AnchorCandidate({ authority, name }), it will throw an error because crunchyAddress has not been initialized. The code will try to use this uninitialized address later in the program.
The solution:
To fix this problem, we need to make sure that crunchyAddress is properly initialized before using it. We can do this by adding a line to set its value or initializing it with a default value. Here is an updated version of the code:
“`typescript
import { AccountInfo } from ‘@solana/web3.js’;
import { ProgramResult, pubkeyToAccount } from ‘@solana/angular-keygen’;
import {
anchorBankrun,
createBanks,
initializeBanks,
} from ‘./anchor-bankrun’;
const crunchyAddress = ‘0xYourCrunchyAddressHere’; // Replace with actual address
const crunchyCandidate = new AnchorCandidate(
{ authority: ‘crunchy-authority’, name: ‘Crunchy Candidate’ }
);
export async function anchorBankrunTest() {
const banks = await createBanks();
const accountInfo = new AccountInfo({ keyId: ‘your-key-id-here’ });
try {
const account = await accountInfo.loadAccount();
if (account.address) {
// Initialize crunchy candidate
const result = await anchorBankrun(banks, account);
console.log(result.error ? ‘Error:’ + result.error.message : ‘Success!’);
} else {
// Do not process initialized address
throw new Error(‘Crunchy address not found’);
}
} catch (error) {
if (error instance of error && error.message.includes(‘initialized address’)) {
throw error;
} else {
console.error(error);
}
}
}
class AnchorCandidate {
constructor({ authority, name }) {
this.authority = authority;
this.
