What are soft assertions in Playwright?

test('verify dashboard widgets', async ({ page }) => {
  await page.goto('/dashboard');

  await expect(page.locator('.widget-revenue')).toBeVisible();   // FAILS — stops here
  await expect(page.locator('.widget-users')).toBeVisible();     // Never runs
  await expect(page.locator('.widget-orders')).toBeVisible();    // Never runs
  await expect(page.locator('.widget-conversion')).toBeVisible(); // Never runs
});
// Only 1 failure reported — you don't know about the other 3

test('verify all dashboard widgets', async ({ page }) => {
  await page.goto('/dashboard');

  // All of these run even if earlier ones fail
  await expect.soft(page.locator('.widget-revenue')).toBeVisible();
  await expect.soft(page.locator('.widget-users')).toBeVisible();
  await expect.soft(page.locator('.widget-orders')).toBeVisible();
  await expect.soft(page.locator('.widget-conversion')).toBeVisible();
  await expect.soft(page.locator('.widget-traffic')).toBeVisible();

  // All failures collected and reported at end of test
});
// Reports: 3 soft assertions failed — widget-users, widget-orders, widget-traffic missing

test('product page verification', async ({ page }) => {
  await page.goto('/products/123');

  // Hard — test won't continue if product page doesn't load
  await expect(page).toHaveURL('/products/123');

  // Soft — collect all UI failures
  await expect.soft(page.locator('.product-title')).toBeVisible();
  await expect.soft(page.locator('.product-price')).toContainText('$');
  await expect.soft(page.locator('.product-image img')).toBeVisible();
  await expect.soft(page.locator('.add-to-cart-btn')).toBeEnabled();
  await expect.soft(page.locator('.product-reviews')).toBeVisible();

  // Hard check at the end — ensure no soft failures before continuing
  expect(test.info().errors).toHaveLength(0); // Fails if any soft assertion failed
});

test('form field validation', async ({ page }, testInfo) => {
  await page.goto('/register');
  await page.getByRole('button', { name: 'Submit' }).click();

  await expect.soft(page.getByText('Email is required')).toBeVisible();
  await expect.soft(page.getByText('Password is required')).toBeVisible();
  await expect.soft(page.getByText('Name is required')).toBeVisible();

  // After collecting all failures
  if (testInfo.errors.length > 0) {
    console.log(`${testInfo.errors.length} validation messages missing`);
  }
});
