Assertionsedit

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.

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 occured 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

Usually, you would combine assertions and matchers in your test like this

SearchResponse seearchResponse = client().prepareSearch() ...;
assertHitCount(searchResponse, 4);
assertFirstHit(searchResponse, hasId("4"));
assertSearchHits(searchResponse, "1", "2", "3", "4");
