Playwright · Matcher

toContainText

Playwright assertions check values and web page state. Web-specific matchers retry until the expected condition passes or the assertion timeout is reached; generic matchers check immediately.

Syntax

expect(value).matcher(expected)
await expect(locator).matcher(expected)
expect.soft(value).matcher(expected)
expect(value).not.matcher(expected)
