# class: LocatorAssertions

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`]:

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

test('status becomes submitted', async ({ page }) => {
  // ...
  await page.click('#submit-button');
  await expect(page.locator('.status')).toHaveText('Submitted');
});
```

```java
...
import static com.microsoft.playwright.assertions.PlaywrightAssertions.assertThat;

public class TestLocator {
  ...
  @Test
  void statusBecomesSubmitted() {
    ...
    page.click("#submit-button");
    assertThat(page.locator(".status")).hasText("Submitted");
  }
}
```

```python async
from playwright.async_api import Page, expect

async def test_status_becomes_submitted(page: Page) -> None:
    # ..
    await page.click("#submit-button")
    await expect(page.locator(".status")).to_have_text("Submitted")
```

```python sync
from playwright.sync_api import Page, expect

def test_status_becomes_submitted(page: Page) -> None:
    # ..
    page.click("#submit-button")
    expect(page.locator(".status")).to_have_text("Submitted")
```

```csharp
using System.Text.RegularExpressions;
using System.Threading.Tasks;
using Microsoft.Playwright.NUnit;
using NUnit.Framework;

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

## property: LocatorAssertions.not
* langs: java, js, csharp
- returns: <[LocatorAssertions]>

Makes the assertion check for the opposite condition. For example, this code tests that the Locator doesn't contain text `"error"`:

```js
await expect(locator).not.toContainText('error');
```

```java
assertThat(locator).not().containsText("error");
```

```csharp
await Expect(locator).Not.ToContainTextAsync("error");
```

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

```js
const locator = page.locator('.title');
await expect(locator).toHaveText(/Welcome, Test User/);
await expect(locator).toHaveText(/Welcome, .*/);
```

```java
assertThat(page.locator(".title")).hasText("Welcome, Test User");
assertThat(page.locator(".title")).hasText(Pattern.compile("Welcome, .*"));
```

```python async
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, .*"))
```

```python sync
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, .*"))
```

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


Note that if array is passed as an expected value, entire lists of elements can be asserted:

```js
const locator = page.locator('list > .component');
await expect(locator).toHaveText(['Text 1', 'Text 2', 'Text 3']);
```

```java
assertThat(page.locator("list > .component")).hasText(new String[] {"Text 1", "Text 2", "Text 3"});
```

```python async
from playwright.async_api import expect

locator = page.locator("list > .component")
await expect(locator).to_have_text(["Text 1", "Text 2", "Text 3"])
```

```python sync
from playwright.sync_api import expect

locator = page.locator("list > .component")
expect(locator).to_have_text(["Text 1", "Text 2", "Text 3"])
```

```csharp
var locator = Page.Locator("list > .component");
await Expect(locator).toHaveTextAsync(new string[]{ "Text 1", "Text 2", "Text 3" });
```

## async method: LocatorAssertions.toHaveValue
* langs:
  - alias-java: hasValue

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

```js
const locator = page.locator('input[type=number]');
await expect(locator).toHaveValue(/[0-9]/);
```

```java
assertThat(page.locator("input[type=number]")).hasValue(Pattern.compile("[0-9]"));
```

```python async
import re

locator = page.locator("input[type=number]")
await expect(locator).to_have_value(re.compile(r"[0-9]"))
```

```python sync
import re
from playwright.sync_api import expect

locator = page.locator("input[type=number]")
expect(locator).to_have_value(re.compile(r"[0-9]"))
```

```csharp
var locator = Page.Locator("input[type=number]");
await Expect(locator).ToHaveValueAsync(new Regex("[0-9]"));
```

### param: LocatorAssertions.toHaveValue.value
- `value` <[string]|[RegExp]>

Expected value.
