I am using below dependencies in my pom.xml file

cucumber-java 4.8.0 cucumber-junit 4.8.0 io.rest-assured 4.1.2 jackson-databind 2.10.1 commons-io 2.6

i am using below code to call API

    FileInputStream fileInputStream = new FileInputStream( new File("jsonFileInput\\pricingAPI.json"));
    RestAssured.baseURI ="my base url here";
    
    given().header("Content-Type","application/json")
    .and()
    .body(IOUtils.toString(fileInputStream,"UTF-8"))
    .when()
    .post("v/pr")
    .then()
    .statusCode(200)
    .and()
    .log().all();

Solution

Please follow

hamcrest tests always fail

https://code.google.com/archive/p/hamcrest/issues/128

Consolidating the solution - Change the order of the jars on the java build path - you will find that the JUnit jar is above the hamcrest.jar. You can move hamcrest above the JUnit jar here and the problem will go away.
