Usage

import re
from playwright.sync_api import expect

locator = page.locator('.title')
expect(locator).to_contain_text("substring")
expect(locator).to_contain_text(re.compile(r"\d messages"))

If you pass an array as an expected value, the expectations are:

  1. Locator resolves to a list of elements.
  2. Elements from a subset of this list contain text from the expected array, respectively.
  3. The matching subset of elements has the same order as the expected array.
  4. 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:

from playwright.sync_api import expect

# ✓ Contains the right items in the right order
expect(page.locator("ul > li")).to_contain_text(["Text 1", "Text 3", "Text 4"])

# ✖ Wrong order
expect(page.locator("ul > li")).to_contain_text(["Text 3", "Text 2"])

# ✖ No item contains this text
expect(page.locator("ul > li")).to_contain_text(["Some 33"])

# ✖ Locator points to the outer list element, not to the list items
expect(page.locator("ul")).to_contain_text(["Text 3"])

Arguments

  • expected str | Pattern | List[str] | List[Pattern] | List[str | Pattern] Added in: v1.18#

    Expected substring or RegExp or a list of those.

  • ignore_case bool (optional) Added in: v1.23#

    Whether to perform case-insensitive match. ignore_case option takes precedence over the corresponding regular expression flag if specified.

  • timeout float (optional) Added in: v1.18#

    Time to retry the assertion for in milliseconds. Defaults to 5000.

  • use_inner_text bool (optional) Added in: v1.18#

    Whether to use element.innerText instead of element.textContent when retrieving DOM node text.

Returns

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.

Arguments

  • role "alert" | "alertdialog" | "application" | "article" | "banner" | "blockquote" | "button" | "caption" | "cell" | "checkbox" | "code" | "columnheader" | "combobox" | "complementary" | "contentinfo" | "definition" | "deletion" | "dialog" | "directory" | "document" | "emphasis" | "feed" | "figure" | "form" | "generic" | "grid" | "gridcell" | "group" | "heading" | "img" | "insertion" | "link" | "list" | "listbox" | "listitem" | "log" | "main" | "marquee" | "math" | "meter" | "menu" | "menubar" | "menuitem" | "menuitemcheckbox" | "menuitemradio" | "navigation" | "none" | "note" | "option" | "paragraph" | "presentation" | "progressbar" | "radio" | "radiogroup" | "region" | "row" | "rowgroup" | "rowheader" | "scrollbar" | "search" | "searchbox" | "separator" | "slider" | "spinbutton" | "status" | "strong" | "subscript" | "superscript" | "switch" | "tab" | "table" | "tablist" | "tabpanel" | "term" | "textbox" | "time" | "timer" | "toolbar" | "tooltip" | "tree" | "treegrid" | "treeitem"#

    Required aria role.

  • timeout float (optional)#

    Time to retry the assertion for in milliseconds. Defaults to 5000.

Returns

to_have_text​

Added in: v1.20 locatorAssertions.to_have_text

Ensures the Locator points to an element with 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

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, .*"))

If you pass an array as an expected value, the expectations are:

  1. Locator resolves to a list of elements.
  2. The number of elements equals the number of expected values in the array.
  3. Elements from the list have text matching expected array values, one by one, in order.

For example, consider the following list:

<ul>
  <li>Text 1</li>
  <li>Text 2</li>
  <li>Text 3</li>
</ul>

Let's see how we can use the assertion:

from playwright.sync_api import expect

# ✓ Has the right items in the right order
expect(page.locator("ul > li")).to_have_text(["Text 1", "Text 2", "Text 3"])

# ✖ Wrong order
expect(page.locator("ul > li")).to_have_text(["Text 3", "Text 2", "Text 1"])

# ✖ Last item does not match
expect(page.locator("ul > li")).to_have_text(["Text 1", "Text 2", "Text"])

# ✖ Locator points to the outer list element, not to the list items
expect(page.locator("ul")).to_have_text(["Text 1", "Text 2", "Text 3"])

Arguments

  • expected str | Pattern | List[str] | List[Pattern] | List[str | Pattern] Added in: v1.18#

    Expected string or RegExp or a list of those.

  • ignore_case bool (optional) Added in: v1.23#

    Whether to perform case-insensitive match. ignore_case option takes precedence over the corresponding regular expression flag if specified.

  • timeout float (optional) Added in: v1.18#

    Time to retry the assertion for in milliseconds. Defaults to 5000.

  • use_inner_text bool (optional) Added in: v1.18#

    Whether to use element.innerText instead of element.textContent when retrieving DOM node text.

Returns

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.

to_have_value​

Added in: v1.20 locatorAssertions.to_have_value

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

Usage

import re
from playwright.sync_api import expect

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

Arguments

  • value str | Pattern Added in: v1.18#

    Expected value.

  • timeout float (optional) Added in: v1.18#

    Time to retry the assertion for in milliseconds. Defaults to 5000.

Returns

to_have_values​

Added in: v1.23 locatorAssertions.to_have_values

Ensures the Locator points to multi-select/combobox (i.e. a select with the multiple attribute) and the specified values are selected.

Usage

For example, given the following element:

<select id="favorite-colors" multiple>
  <option value="R">Red</option>
  <option value="G">Green</option>
  <option value="B">Blue</option>
</select>
import re
from playwright.sync_api import expect

locator = page.locator("id=favorite-colors")
locator.select_option(["R", "G"])
expect(locator).to_have_values([re.compile(r"R"), re.compile(r"G")])

Arguments

Returns
