docs/src/api/class-locatorassertions.md
The [LocatorAssertions] class provides assertion methods that can be used to make assertions about the [Locator] state in the tests.
import { test, expect } from '@playwright/test';
test('status becomes submitted', async ({ page }) => {
// ...
await page.getByRole('button').click();
await expect(page.locator('.status')).toHaveText('Submitted');
});
// ...
import static com.microsoft.playwright.assertions.PlaywrightAssertions.assertThat;
public class TestLocator {
// ...
@Test
void statusBecomesSubmitted() {
// ...
page.getByRole(AriaRole.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.get_by_role("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.get_by_role("button").click()
expect(page.locator(".status")).to_have_text("Submitted")
using Microsoft.Playwright;
using Microsoft.Playwright.MSTest;
namespace PlaywrightTests;
[TestClass]
public class ExampleTests : PageTest
{
[TestMethod]
public async Task StatusBecomesSubmitted()
{
// ...
await Page.GetByRole(AriaRole.Button, new() { Name = "Sign In" }).ClickAsync();
await Expect(Page.Locator(".status")).ToHaveTextAsync("Submitted");
}
}
Makes the assertion check for the opposite condition.
Usage
For example, this code tests that the Locator doesn't contain text "error":
await expect(locator).not.toContainText('error');
assertThat(locator).not().containsText("error");
await Expect(locator).Not.ToContainTextAsync("error");

await expect(
page.get_by_role("button", name="Sign in")
.or_(page.get_by_role("button", name="Sign up"))
.first
).to_be_visible()
# A specific element is visible.
expect(page.get_by_text("Welcome")).to_be_visible()
# At least one item in the list is visible.
expect(page.get_by_test_id("todo-item").first).to_be_visible()
# At least one of the two elements is visible, possibly both.
expect(
page.get_by_role("button", name="Sign in")
.or_(page.get_by_role("button", name="Sign up"))
.first
).to_be_visible()
// A specific element is visible.
await Expect(Page.GetByText("Welcome")).ToBeVisibleAsync();
// At least one item in the list is visible.
await Expect(Page.GetByTestId("todo-item").First).ToBeVisibleAsync();
// At least one of the two elements is visible, possibly both.
await Expect(
Page.GetByRole(AriaRole.Button, new() { Name = "Sign in" })

.First
).ToBeVisibleAsync();
visible <[boolean]>Ensures the [Locator] points to an element with given CSS classes. All classes from the asserted value, separated by spaces, must be present in the Element.classList in any order.
Usage
<div class='middle selected row' id='component'></div>
const locator = page.locator('#component');
await expect(locator).toContainClass('middle selected row');
await expect(locator).toContainClass('selected');
await expect(locator).toContainClass('row middle');
assertThat(page.locator("#component")).containsClass("middle selected row");
assertThat(page.locator("#component")).containsClass("selected");
assertThat(page.locator("#component")).containsClass("row middle");
from playwright.async_api import expect
locator = page.locator("#component")
await expect(locator).to_contain_class("middle selected row")
await expect(locator).to_contain_class("selected")
await expect(locator).to_contain_class("row middle")
from playwright.sync_api import expect
locator = page.locator("#component")
expect(locator).to_contain_class("middle selected row")

var locator = Page.Locator("#component");
await Expect(locator).ToContainClassAsync("middle selected row");
await Expect(locator).ToContainClassAsync("selected");
await Expect(locator).ToContainClassAsync("row middle");
When an array is passed, the method asserts that the list of elements located matches the corresponding list of expected class lists. Each element's class attribute is matched against the corresponding class in the array:
<div class='list'>
<div class='component inactive'></div>
<div class='component active'></div>
<div class='component inactive'></div>
</div>
const locator = page.locator('.list > .component');
await expect(locator).toContainClass(['inactive', 'active', 'inactive']);

expected <[string]|[Array]<[string]>>A string containing expected class names, separated by spaces, or a list of such strings to assert multiple elements.
Ensures the [Locator] points to an element that contains the given text. All nested elements will be considered when computing the text content of the element. You can use regular expressions for the value as well.
Details
When expected parameter is a string, Playwright will normalize whitespaces and line breaks both in the actual text and
in the expected string before matching. When regular expression is used, the actual text is matched as is.
Usage
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:
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"});
// ✖ 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"});

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

# ✖ 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"});
// ✖ Wrong order
await Expect(Page.Locator("ul > li")).ToContainTextAsync(new string[] {"Text 3", "Text 2"});
// ✖ No item contains this text
await Expect(Page.Locator("ul > li")).ToContainTextAsync(new string[] {"Some 33"});
// ✖ Locator points to the outer list element, not to the list items
await Expect(Page.Locator("ul")).ToContainTextAsync(new string[] {"Text 3"});

name <[string]>Property name.
value <[any]>Property value.
Ensures the [Locator] points to an element with a given ARIA role.
Note that role is matched as a string, disregarding the ARIA role hierarchy. For example, asserting a superclass role "checkbox" on an element with a subclass role "switch" will fail.
Usage
const locator = page.getByTestId('save-button');
await expect(locator).toHaveRole('button');
Locator locator = page.getByTestId("save-button");
assertThat(locator).hasRole(AriaRole.BUTTON);
locator = page.get_by_test_id("save-button")
await expect(locator).to_have_role("button")
locator = page.get_by_test_id("save-button")
expect(locator).to_have_role("button")
var locator = Page.GetByTestId("save-button");
await Expect(locator).ToHaveRoleAsync(AriaRole.Button);
This function will wait until two consecutive locator screenshots yield the same result, and then compare the last screenshot with the expectation.
Usage
const locator = page.getByRole('button');
await expect(locator).toHaveScreenshot('image.png');
Note that screenshot assertions only work with Playwright test runner.
name <[string]|[Array]<[string]>>Snapshot name.
This function will wait until two consecutive locator screenshots yield the same result, and then compare the last screenshot with the expectation.
Usage
const locator = page.getByRole('button');
await expect(locator).toHaveScreenshot();
Note that screenshot assertions only work with Playwright test runner.
Ensures the [Locator] points to an element with the given text. All nested elements will be considered when computing the text content of the element. You can use regular expressions for the value as well.
Details
When expected parameter is a string, Playwright will normalize whitespaces and line breaks both in the actual text and
in the expected string before matching. When regular expression is used, the actual text is matched as is.
Usage
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"))
expect(locator).to_have_text(re.compile(r"Welcome, .*"))
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:
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
expect(page.locator("ul > li")).to_have_text(["Text 1", "Text 2", "Text 3"])
# ✖ Wrong order

# ✖ Last item does not match
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
expect(page.locator("ul")).to_have_text(["Text 1", "Text 2", "Text 3"])

// ✖ 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"});

Usage
const locator = page.locator('input[type=number]');
await expect(locator).toHaveValue(/[0-9]/);
assertThat(page.locator("input[type=number]")).hasValue(Pattern.compile("[0-9]"));
import re
from playwright.async_api import expect

var locator = Page.Locator("input[type=number]");
await Expect(locator).ToHaveValueAsync(new Regex("[0-9]"));
value <[string]|[RegExp]>Expected value.
Ensures the [Locator] points to multi-select/combobox (i.e. a select with the multiple attribute) and the specified values are selected.
Usage
For example, given the following element:
<select id="favorite-colors" multiple>
<option value="R">Red</option>
<option value="G">Green</option>
<option value="B">Blue</option>
</select>
const locator = page.locator('id=favorite-colors');
await locator.selectOption(['R', 'G']);
await expect(locator).toHaveValues([/R/, /G/]);
page.locator("id=favorite-colors").selectOption(new String[]{"R", "G"});
assertThat(page.locator("id=favorite-colors")).hasValues(new Pattern[] { Pattern.compile("R"), Pattern.compile("G") });
import re
from playwright.async_api import expect
locator = page.locator("id=favorite-colors")
await locator.select_option(["R", "G"])
await expect(locator).to_have_values([re.compile(r"R"), re.compile(r"G")])
import re
from playwright.sync_api import expect
locator = page.locator("id=favorite-colors")
locator.select_option(["R", "G"])
expect(locator).to_have_values([re.compile(r"R"), re.compile(r"G")])
var locator = Page.Locator("id=favorite-colors");
await locator.SelectOptionAsync(new string[] { "R", "G" });
await Expect(locator).ToHaveValuesAsync(new Regex[] { new Regex("R"), new Regex("G") });
