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

containsClass

Added in: v1.52

locatorAssertions.containsClass

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>

assertThat(page.locator("#component")).containsClass("middle selected row");
assertThat(page.locator("#component")).containsClass("selected");
assertThat(page.locator("#component")).containsClass("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>

assertThat(page.locator(".list > .component")).containsClass(new String[] {"inactive", "active", "inactive"});

Arguments

expected String | List<String>#

A string containing expected class names, separated by spaces, or a list of such strings to assert multiple elements.
options LocatorAssertions.ContainsClassOptions (optional)
- setTimeout double (optional)#
  
  Time to retry the assertion for in milliseconds. Defaults to 5000.

Returns

void #

containsText

Added in: v1.20

locatorAssertions.containsText

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.

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

expected String | Pattern | String[] | Pattern[] Added in: v1.18#

Expected substring or RegExp or a list of those.
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.
- setTimeout double (optional) Added in: v1.18#
  
  Time to retry the assertion for in milliseconds. Defaults to 5000.
- setUseInnerText boolean (optional) Added in: v1.18#
  
  Whether to use element.innerText instead of element.textContent when retrieving DOM node text.

Returns

void #

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.
