MockServer verify with multiple body matchers


I'm using MockServer body matchers to verify an endpoint request's body parameters. Some properties can be matched exactly, but others may need a separate subString or regex matcher, because part of that property is unknown. For example, a date-time string may have a known date, but unknown time.

However, with multiple withBody() calls, the verify method passes if one or more matcher passes. How to implement a logical AND instead of an OR?

mockServer.verify(
    request()
        .withPath(url)
        .withMethod("POST")
        .withBody(
            json(
                "{\"firstName\": \"foo\",\"lastName\": \"bar\"}",
                MatchType.ONLY_MATCHING_FIELDS))
        .withBody(
            // Need subString because we don't know the time and only want to validate the date
            subString("\"order_date_time\": \"2021-04-15")));

Solution

  • To perform a logical-AND on multiple body matcher criteria, you need to call the verify() method multiple times:

    private void verifyOrderPlaced() {
      verifyName();
      verifyOrderDate();
    }
    
    private void verifyName() {
      mockServer.verify(
          request()
              .withPath(url)
              .withMethod("POST")
              .withBody(
                  json(
                      "{\"firstName\": \"foo\",\"lastName\": \"bar\"}",
                      MatchType.ONLY_MATCHING_FIELDS)));
    }
    
    private void verifyOrderDate() {
      mockServer.verify(
          request()
              .withPath(url)
              .withMethod("POST")
              .withBody(
                  subString("\"order_date_time\": \"2021-04-15")));
    }
