# class: LocatorAssertions
* langs: java, python

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.assertThatLocator`]:

```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");
  }
}
```

## method: LocatorAssertions.not
* langs: java
- returns: <[LocatorAssertions]>

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

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