variables from your model are also going to be untrusted. That means that if
your code interacts with the filesystem, network, etc. and uses checkpointed
variables as part of those interactions (ex: using a string variable to build a
filesystem path), a maliciously created checkpoint might be able to change the
targets of those operations, which could result in arbitrary
read/write/executions.

from your test's `tearDown()`.

### API

#### MockResponse

Mock responses default to an empty response body and a `200` status code.
You can set a custom body with a string, input stream or byte array. Also
add headers with a fluent builder API.

### Java
```java
MockResponse response = new MockResponse.Builder()
    .addHeader("Content-Type", "application/json; charset=utf-8")

    @Override
    public String toString() {
        if (isEmpty()) {
            return "empty";
        }
        StringBuilder sb = new StringBuilder(512);
        for (MetadataGraphVertex v : vertices) {
            sb.append("Vertex:  ").append(v.getMd().toString()).append('\n');
            List<MetadataGraphEdge> ins = getIncidentEdges(v);

## Set types { #set-types }

But then we think about it, and realize that tags shouldn't repeat, they would probably be unique strings.

And Python has a special data type for sets of unique items, the `set`.

Then we can declare `tags` as a set of strings:

          @Override
          public ListenableFuture<T> call() throws Exception {
            return immediateFuture(callable.call());
          }

          @Override
          public String toString() {
            return callable.toString();
          }
        },
        executor);
  }

  /**
   * Enqueues a task to run when the previous task (if any) completes.

      }
      return false;
    }

    @Override
    public int hashCode() {
      return asMapOfRanges().hashCode();
    }

    @Override
    public String toString() {
      return asMapOfRanges().toString();
    }

    class SubRangeMapAsMap extends AbstractMap<Range<K>, V> {

      @Override
      public boolean containsKey(@Nullable Object key) {
        return get(key) != null;

            response.readDataWireFormat(buffer, 0, buffer.length);
        });
    }

    @Test
    @DisplayName("Test toString method")
    void testToString() {
        String result = response.toString();
        assertNotNull(result);
        // The toString method includes various parameter information
        assertTrue(result.contains("totalParameterCount"));

            }

            @Override
            public void close() throws CIFSException {
                // Do nothing
            }

            private FileNotifyInformation createMockNotification(String filename) {
                FileNotifyInformation info = mock(FileNotifyInformation.class);
                when(info.getFileName()).thenReturn(filename);

        assertTrue("URL without host should not cause delay", elapsed < 50);
    }

    /**

                }
            }
            andx.received = true;
        }

        return bufferIndex - start;
    }

    @Override

        return super.toString() + ",andxCommand=0x" + Hexdump.toHexString(andxCommand, 2) + ",andxOffset=" + andxOffset;
