Scenario: lotto resource returns 200 with expected id and winners
Given path ‘lotto’, 5
When method get
Then status 200
And match $.lotto.lottoId == 5
And match $.lotto.winners[*].winnerId contains only [23, 54]
given().
param("key1", "value1").
param("key2", "value2").
when().
get("/somewhere").
then().
body(containsString("OK"));
Given param key1 = ‘value1’
And param key2 = ‘value2’
And path ‘somewhere’
When method get
Then response contains ‘OK’

No Java coding / compilation required ❌ ✅

apidays LIVE India - Karate for REST and GraphQL test automation by Peter Thomas, Intuit
The document discusses Karate, an open-source test automation framework by Intuit, released in February 2017, which simplifies API testing and incorporates BDD syntax inspired by Cucumber. It highlights its capabilities such as performance testing, data-driven testing, and various integrations, while comparing it to other tools like Rest-Assured. Additionally, it emphasizes features such as no required Java coding, parallel execution, and built-in step definitions without the need for Java code.
