When tests pass individually but fail when run together in a group, it's often due to shared state or dependencies between tests. In @playwright/test, this can happen for several reasons:
test.beforeEach
and test.afterEach
hooks.import { test, expect } from '@playwright/test';
test.beforeEach(async ({ context }) => {
await context.newPage();
});
test.afterEach(async ({ context }) => {
await context.close();
});
test('Test 1', async ({ page }) => {
await page.goto('https://ray.run/');
// Perform test actions
});
test('Test 2', async ({ page }) => {
await page.goto('https://ray.run/');
// Perform test actions
});
Test order dependency: Ensure your tests are independent and can run in any order. Avoid relying on the outcome of a previous test for the next test to succeed.
Concurrency issues: When running tests in parallel, shared resources or race conditions might cause unexpected failures. Use test.serial
to run tests sequentially if they depend on shared resources.
import { test, expect } from '@playwright/test';
test.serial('Test 1', async ({ page }) => {
await page.goto('https://ray.run/');
// Perform test actions
});
test.serial('Test 2', async ({ page }) => {
await page.goto('https://ray.run/');
// Perform test actions
});
import { test, expect } from '@playwright/test';
test.setTimeout(10000); // Set the timeout to 10 seconds
test('Test with increased timeout', async ({ page }) => {
await page.goto('https://ray.run/');
// Perform test actions
});
By addressing these issues, you can ensure your tests run reliably both individually and in groups. For more tips on writing efficient @playwright/test scripts, check out this blog post.
