The `TestClient` is based on <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a>, and luckily, we can use it directly to test the API.

## Example

  optional string type = 1;

  // Status of the condition, one of True, False, Unknown.
  // +required
  optional string status = 2;

  // If set, this represents the .metadata.generation that the condition was set based upon.
  // +optional
  optional int64 observedGeneration = 3;

  // Last time the condition transitioned from one status to another.
  // +required

 * }</pre>
 *
 * This works because those types each implement {@code PredecessorsFunction}. It will also work
 * with any other implementation of this interface.
 *
 * <p>If you have your own graph implementation based around a custom node type {@code MyNode},
 * which has a method {@code getParents()} that retrieves its predecessors in a graph:
 *
 * <pre>{@code
 * someGraphAlgorithm(startNode, MyNode::getParents);
 * }</pre>
