Definition

Assembly: CloudNimble.Breakdance.Assemblies.dll

Namespace: CloudNimble.Breakdance.Assemblies.Http

Inheritance: CloudNimble.Breakdance.Assemblies.Http.ResponseSnapshotHandlerBase

Syntax

CloudNimble.Breakdance.Assemblies.Http.ResponseSnapshotReplayHandler

Summary

A DelegatingHandler that replays previously captured HTTP responses from snapshot files.

Remarks

This handler intercepts outgoing HTTP requests and returns responses from snapshot files instead of making actual network calls. This enables deterministic testing against real response data without hitting live endpoints.

Response snapshots are typically captured using ResponseSnapshotCaptureHandler during an initial recording phase, then replayed during test execution.

Examples

// Create a handler that reads from snapshot files
var handler = new ResponseSnapshotReplayHandler("TestData/Snapshots");
var client = new HttpClient(handler);

// Requests will be served from snapshot files instead of the network
var response = await client.GetAsync("https://api.example.com/users");

Constructors

.ctor

Syntax

public ResponseSnapshotReplayHandler(string responseSnapshotsPath)

Parameters

Name	Type	Description
responseSnapshotsPath	string	Root folder path containing response snapshot files.

.ctor Inherited

Inherited from CloudNimble.Breakdance.Assemblies.Http.ResponseSnapshotHandlerBase

Creates a new ResponseSnapshotHandlerBase with the specified snapshot storage path.

Syntax

public ResponseSnapshotHandlerBase(string responseSnapshotsPath)

Parameters

Name	Type	Description
responseSnapshotsPath	string	Root folder path for storing response snapshot files.

Examples

var handler = new ResponseSnapshotReplayHandler("TestData/Snapshots");
