As many elasticsearch tests are checking for a similar output, like the amount of hits or the first hit or special highlighting, a couple of predefined assertions have been created. Those have been put into the ElasticsearchAssertions class. There is also a specific geo assertions in ElasticsearchGeoAssertions.
| assertHitCount() | Checks hit count of a search or count request |
| assertAcked() | Ensure the a request has been acknowledged by the master |
| assertSearchHits() | Asserts a search response contains specific ids |
| assertMatchCount() | Asserts a matching count from a percolation response |
| assertFirstHit() | Asserts the first hit hits the specified matcher |
| assertSecondHit() | Asserts the second hit hits the specified matcher |
| assertThirdHit() | Asserts the third hits hits the specified matcher |
| assertSearchHit() | Assert a certain element in a search response hits the specified matcher |
| assertNoFailures() | Asserts that no shard failures have occurred in the response |
| assertFailures() | Asserts that shard failures have happened during a search request |
| assertHighlight() | Assert specific highlights matched |
| assertSuggestion() | Assert for specific suggestions |
| assertSuggestionSize() | Assert for specific suggestion count |
| assertThrows() | Assert a specific exception has been thrown |
Common matchers
| hasId() | Matcher to check for a search hit id |
| hasType() | Matcher to check for a search hit type |
| hasIndex() | Matcher to check for a search hit index |
| hasScore() | Matcher to check for a certain score of a hit |
| hasStatus() | Matcher to check for a certain RestStatus of a response |
Usually, you would combine assertions and matchers in your test like this
