# class: PageAssertions
|
|
* since: v1.17
|
|
|
|
The [PageAssertions] class provides assertion methods that can be used to make assertions about the [Page] state in the tests.
|
|
|
|
```js
|
|
import { test, expect } from '@playwright/test';
|
|
|
|
test('navigates to login', async ({ page }) => {
|
|
// ...
|
|
await page.getByText('Sign in').click();
|
|
await expect(page).toHaveURL(/.*\/login/);
|
|
});
|
|
```
|
|
|
|
```java
|
|
...
|
|
import static com.microsoft.playwright.assertions.PlaywrightAssertions.assertThat;
|
|
|
|
public class TestPage {
|
|
...
|
|
@Test
|
|
void navigatesToLoginPage() {
|
|
...
|
|
page.getByText("Sign in").click();
|
|
assertThat(page).hasURL(Pattern.compile(".*/login"));
|
|
}
|
|
}
|
|
```
|
|
|
|
```python async
|
|
import re
|
|
from playwright.async_api import Page, expect
|
|
|
|
async def test_navigates_to_login_page(page: Page) -> None:
|
|
# ..
|
|
await page.get_by_text("Sign in").click()
|
|
await expect(page).to_have_url(re.compile(r".*/login"))
|
|
```
|
|
|
|
```python sync
|
|
import re
|
|
from playwright.sync_api import Page, expect
|
|
|
|
def test_navigates_to_login_page(page: Page) -> None:
|
|
# ..
|
|
page.get_by_text("Sign in").click()
|
|
expect(page).to_have_url(re.compile(r".*/login"))
|
|
```
|
|
|
|
```csharp
|
|
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 NavigatetoLoginPage()
|
|
{
|
|
// ..
|
|
await Page.GetByText("Sing in").ClickAsync();
|
|
await Expect(Page.Locator("div#foobar")).ToHaveURL(new Regex(".*/login"));
|
|
}
|
|
}
|
|
```
|
|
|
|
## property: PageAssertions.not
|
|
* since: v1.20
|
|
* langs: java, js, csharp
|
|
- returns: <[PageAssertions]>
|
|
|
|
Makes the assertion check for the opposite condition. For example, this code tests that the page URL doesn't contain `"error"`:
|
|
|
|
```js
|
|
await expect(page).not.toHaveURL('error');
|
|
```
|
|
|
|
```java
|
|
assertThat(page).not().hasURL("error");
|
|
```
|
|
|
|
```csharp
|
|
await Expect(Page).Not.ToHaveURL("error");
|
|
```
|
|
|
|
