::assertRaw() and ::assertText() are undefined in Drupal 10

Problem/Motivation

As described in Simpletest's legacy assertion methods are deprecated → , methods like ::assertRaw() and ::assertText() have been deprecated in Drupal 9, and removed in Drupal 10. Running tests on Drupal 10 would cause the tests to fail.

Proposed resolution

• Replace any call to $this->assertRaw() done in tests with $this->assertSession()->responseContains()
• Replace any call to $this->assertText() done in tests with $this->assertSession()->responseContains() or $this->assertSession()->pageTextContains()
