Authors Karate `.feature` files using its Gherkin-flavored DSL for HTTP API tests, leverages the `match` keyword with fuzzy validators (#number / #string / #regex / contains / arrays), runs the suite via JUnit 5 plus Maven Surefire, and produces JUnit XML for CI gating. Use when the project is on the JVM and prefers a feature-file authoring flow over Java-DSL fluent chains; for those fluent chains use restassured-testing, for the same YAML-style flow on a Python/pytest stack use tavern-testing.
