To implement a retry mechanism in @playwright/test, you can use a try-catch block with a loop for retries. Here's a TypeScript example of how to do this in a beforeAll
hook:
import { test } from '@playwright/test';
const MAX_RETRIES = 3;
const RETRY_DELAY = 1000;
async function fetchBearerToken(): Promise<string> {
// Your implementation for fetching the bearer token
}
async function fetchTokenWithRetry(): Promise<string> {
let retries = 0;
while (retries < MAX_RETRIES) {
try {
const token = await fetchBearerToken();
return token;
} catch (error) {
console.error(`Fetch attempt ${retries + 1} failed: ${error.message}`);
retries++;
if (retries < MAX_RETRIES) {
await new Promise(resolve => setTimeout(resolve, RETRY_DELAY));
}
}
}
throw new Error('Failed to fetch bearer token after maximum retries');
}
test.beforeAll(async ({}, use) => {
const token = await fetchTokenWithRetry();
use({ token });
});
test('example test', async ({ token }) => {
// Your test implementation using the fetched token
});
In this example, the fetchTokenWithRetry
function attempts to fetch the bearer token using the fetchBearerToken
function. If it fails, it retries up to MAX_RETRIES
times with a delay of RETRY_DELAY
milliseconds between each attempt.
Remember that adding retries may not always be the best solution, depending on the cause of the failure. If there's an issue with network connectivity or server availability, retries might not help and could prolong test execution times unnecessarily.
