function SearchExcerptTest::testSearchExcerptSimplified in Zircon Profile 8

Same name and namespace in other branches
8.0 core/modules/search/src/Tests/SearchExcerptTest.php \Drupal\search\Tests\SearchExcerptTest::testSearchExcerptSimplified()
Tests search_excerpt() with search keywords matching simplified words.
Excerpting should handle keywords that are matched only after going through search_simplify(). This test passes keywords that match simplified words and compares them with strings that contain the original unsimplified word.
