### Question:
AwsNetworkV4Parameters extends MappableBase { @Override public void parse(Map<String, Object> parameters) { subnetId = getParameterOrNull(parameters, "subnetId"); }  String getSubnetId(); void setSubnetId(String subnetId); @Override Map<String, Object> asMap(); @Override @JsonIgnore @ApiModelProperty(hidden = true) CloudPlatform getCloudPlatform(); @Override void parse(Map<String, Object> parameters);  }### Answer:
@Test public void testParse() { Map<String, Object> parameters = Map.of("subnetId", "subnet-1234"); underTest.parse(parameters); assertEquals("subnet-1234", underTest.getSubnetId()); }
