@Test public void testGetModelPathWhenDMNModelCouldNotBeFound() { final Metadata metadata = mock(Metadata.class); final String modelNamespace = "0000-1111-2222-3333"; final String modelName = "model name"; assertThatThrownBy(() -> helper.getDMNModelPath(metadata, modelNamespace, modelName)) .isInstanceOf(IllegalStateException.class) .hasMessageContaining("A path for the DMN model with namespace [0000-1111-2222-3333] could not be found."); }
