class: LocatorAssertions

  • since: v1.17

The [LocatorAssertions] class provides assertion methods that can be used to make assertions about the [Locator] state in the tests. A new instance of [LocatorAssertions] is created by calling [method: PlaywrightAssertions.expectLocator]:

import { test, expect } from '@playwright/test';

test('status becomes submitted', async ({ page }) => {
  // ...
  await page.locator('#submit-button').click();
  await expect(page.locator('.status')).toHaveText('Submitted');
});
...
import static com.microsoft.playwright.assertions.PlaywrightAssertions.assertThat;

public class TestLocator {
  ...
  @Test
  void statusBecomesSubmitted() {
    ...
    page.locator("#submit-button").click();
    assertThat(page.locator(".status")).hasText("Submitted");
  }
}
from playwright.async_api import Page, expect

async def test_status_becomes_submitted(page: Page) -> None:
    # ..
    await page.locator("#submit-button").click()
    await expect(page.locator(".status")).to_have_text("Submitted")
from playwright.sync_api import Page, expect

def test_status_becomes_submitted(page: Page) -> None:
    # ..
    page.locator("#submit-button").click()
    expect(page.locator(".status")).to_have_text("Submitted")
using System.Text.RegularExpressions;
using System.Threading.Tasks;
using Microsoft.Playwright.NUnit;
using NUnit.Framework;

namespace PlaywrightTests;

[TestFixture]
public class ExampleTests : PageTest
{
    [Test]
    public async Task StatusBecomesSubmitted()
    {
        // ..
        await Page.Locator("#submit-button").ClickAsync();
        await Expect(Page.Locator(".status")).ToHaveTextAsync("Submitted");
    }
}

async method: LocatorAssertions.toContainText

  • since: v1.20
  • langs:
    • alias-java: containsText

Ensures the [Locator] points to an element that contains the given text. You can use regular expressions for the value as well.

const locator = page.locator('.title');
await expect(locator).toContainText('substring');
await expect(locator).toContainText(/\d messages/);
assertThat(page.locator(".title")).containsText("substring");
import re
from playwright.async_api import expect

locator = page.locator('.title')
await expect(locator).to_contain_text("substring")
await expect(locator).to_contain_text(re.compile(r"\d messages"))
import re
from playwright.sync_api import expect

locator = page.locator('.title')
expect(locator).to_contain_text("substring")
expect(locator).to_contain_text(re.compile(r"\d messages"))
var locator = Page.Locator(".title");
await Expect(locator).ToContainTextAsync("substring");
await Expect(locator).ToContainTextAsync(new Regex("\\d messages"));

If you pass an array as an expected value, the expectations are:

  1. Locator resolves to a list of elements.
  2. Elements from a subset of this list contain text from the expected array, respectively.
  3. The matching subset of elements has the same order as the expected array.
  4. Each text value from the expected array is matched by some element from the list.

For example, consider the following list:

<ul>
  <li>Item Text 1</li>
  <li>Item Text 2</li>
  <li>Item Text 3</li>
</ul>

Let's see how we can use the assertion:

// ✓ Contains the right items in the right order
await expect(page.locator('ul > li')).toContainText(['Text 1', 'Text 3']);

// ✖ Wrong order
await expect(page.locator('ul > li')).toContainText(['Text 3', 'Text 2']);

// ✖ No item contains this text
await expect(page.locator('ul > li')).toContainText(['Some 33']);

// ✖ Locator points to the outer list element, not to the list items
await expect(page.locator('ul')).toContainText(['Text 3']);
// ✓ Contains the right items in the right order
assertThat(page.locator("ul > li")).containsText(new String[] {"Text 1", "Text 3", "Text 4"});

// ✖ Wrong order
assertThat(page.locator("ul > li")).containsText(new String[] {"Text 3", "Text 2"});

// ✖ No item contains this text
assertThat(page.locator("ul > li")).containsText(new String[] {"Some 33"});

// ✖ Locator points to the outer list element, not to the list items
assertThat(page.locator("ul")).containsText(new String[] {"Text 3"});
from playwright.async_api import expect

# ✓ Contains the right items in the right order
await expect(page.locator("ul > li")).to_contain_text(["Text 1", "Text 3", "Text 4"])

# ✖ Wrong order
await expect(page.locator("ul > li")).to_contain_text(["Text 3", "Text 2"])

# ✖ No item contains this text
await expect(page.locator("ul > li")).to_contain_text(["Some 33"])

# ✖ Locator points to the outer list element, not to the list items
await expect(page.locator("ul")).to_contain_text(["Text 3"])
from playwright.sync_api import expect

# ✓ Contains the right items in the right order
expect(page.locator("ul > li")).to_contain_text(["Text 1", "Text 3", "Text 4"])

# ✖ Wrong order
expect(page.locator("ul > li")).to_contain_text(["Text 3", "Text 2"])

# ✖ No item contains this text
expect(page.locator("ul > li")).to_contain_text(["Some 33"])

# ✖ Locator points to the outer list element, not to the list items
expect(page.locator("ul")).to_contain_text(["Text 3"])
// ✓ Contains the right items in the right order
await Expect(Page.Locator("ul > li")).ToContainTextAsync(new string[] {"Text 1", "Text 3", "Text 4"});

// ✖ Wrong order
await Expect(Page.Locator("ul > li")).ToContainTextAsync(new string[] {"Text 3", "Text 2"});

// ✖ No item contains this text

async method: LocatorAssertions.toHaveText

  • since: v1.20
  • langs:
    • alias-java: hasText

Ensures the [Locator] points to an element with the given text. You can use regular expressions for the value as well.

const locator = page.locator('.title');
await expect(locator).toHaveText(/Welcome, Test User/);
await expect(locator).toHaveText(/Welcome, .*/);
assertThat(page.locator(".title")).hasText("Welcome, Test User");
assertThat(page.locator(".title")).hasText(Pattern.compile("Welcome, .*"));
import re
from playwright.async_api import expect

locator = page.locator(".title")
await expect(locator).to_have_text(re.compile(r"Welcome, Test User"))
await expect(locator).to_have_text(re.compile(r"Welcome, .*"))
import re
from playwright.sync_api import expect

locator = page.locator(".title")
expect(locator).to_have_text(re.compile(r"Welcome, Test User"))

var locator = Page.Locator(".title");
await Expect(locator).ToHaveTextAsync(new Regex("Welcome, Test User"));
await Expect(locator).ToHaveTextAsync(new Regex("Welcome, .*"));

If you pass an array as an expected value, the expectations are:

  1. Locator resolves to a list of elements.
  2. The number of elements equals the number of expected values in the array.
  3. Elements from the list have text matching expected array values, one by one, in order.

For example, consider the following list:

<ul>
  <li>Text 1</li>
  <li>Text 2</li>
  <li>Text 3</li>
</ul>

Let's see how we can use the assertion:

// ✓ Has the right items in the right order
await expect(page.locator('ul > li')).toHaveText(['Text 1', 'Text 2', 'Text 3']);

// ✖ Wrong order
await expect(page.locator('ul > li')).toHaveText(['Text 3', 'Text 2', 'Text 1']);

// ✖ Last item does not match
await expect(page.locator('ul > li')).toHaveText(['Text 1', 'Text 2', 'Text']);

// ✖ Locator points to the outer list element, not to the list items
await expect(page.locator('ul')).toHaveText(['Text 1', 'Text 2', 'Text 3']);
// ✓ Has the right items in the right order
assertThat(page.locator("ul > li")).hasText(new String[] {"Text 1", "Text 2", "Text 3"});

// ✖ Wrong order
assertThat(page.locator("ul > li")).hasText(new String[] {"Text 3", "Text 2", "Text 1"});

// ✖ Last item does not match
assertThat(page.locator("ul > li")).hasText(new String[] {"Text 1", "Text 2", "Text"});

// ✖ Locator points to the outer list element, not to the list items
assertThat(page.locator("ul")).hasText(new String[] {"Text 1", "Text 2", "Text 3"});
from playwright.async_api import expect

# ✓ Has the right items in the right order
await expect(page.locator("ul > li")).to_have_text(["Text 1", "Text 2", "Text 3"])

# ✖ Wrong order
await expect(page.locator("ul > li")).to_have_text(["Text 3", "Text 2", "Text 1"])

# ✖ Last item does not match
await expect(page.locator("ul > li")).to_have_text(["Text 1", "Text 2", "Text"])

# ✖ Locator points to the outer list element, not to the list items
await expect(page.locator("ul")).to_have_text(["Text 1", "Text 2", "Text 3"])
from playwright.sync_api import expect

# ✓ Has the right items in the right order
await expect(page.locator("ul > li")).to_have_text(["Text 1", "Text 2", "Text 3"])

# ✖ Wrong order
await expect(page.locator("ul > li")).to_have_text(["Text 3", "Text 2", "Text 1"])

# ✖ Last item does not match
await expect(page.locator("ul > li")).to_have_text(["Text 1", "Text 2", "Text"])

# ✖ Locator points to the outer list element, not to the list items
await expect(page.locator("ul")).to_have_text(["Text 1", "Text 2", "Text 3"])
// ✓ Has the right items in the right order
await Expect(Page.Locator("ul > li")).ToHaveTextAsync(new string[] {"Text 1", "Text 2", "Text 3"});

// ✖ Wrong order
await Expect(Page.Locator("ul > li")).ToHaveTextAsync(new string[] {"Text 3", "Text 2", "Text 1"});

// ✖ Last item does not match
await Expect(Page.Locator("ul > li")).ToHaveTextAsync(new string[] {"Text 1", "Text 2", "Text"});

// ✖ Locator points to the outer list element, not to the list items
await Expect(Page.Locator("ul")).ToHaveTextAsync(new string[] {"Text 1", "Text 2", "Text 3"});
