LocatorAssertions
The LocatorAssertions class provides assertion methods that can be used to make assertions about the Locator state in the tests.
// ...
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");
}
}
Methods
containsText
Added in: v1.20Ensures 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.
Usage
assertThat(page.locator(".title")).containsText("substring");
If you pass an array as an expected value, the expectations are:
- Locator resolves to a list of elements.
- Elements from a subset of this list contain text from the expected array, respectively.
- The matching subset of elements has the same order as the expected array.
- 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
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"});
Arguments

options
LocatorAssertions.ContainsTextOptions
(optional)-
setIgnoreCase
boolean (optional) Added in: v1.23#Whether to perform case-insensitive match. setIgnoreCase option takes precedence over the corresponding regular expression flag if specified.

Usage
assertThat(page.locator(".title")).hasText("Welcome, Test User");
