  • Requests
  • Scenarios

Installation

npm install wiremock-rest-client

Usage

The WireMockRestClient has 5 services which correspond with request paths as specified in the OpenAPI spec.

• global - Global operations
• mappings - Operations on stub mappings
• recordings - Stub mapping record and snapshot functions
• requests - Logged requests and responses received
• scenarios - Scenarios support modeling of stateful behavior

See the API for the available methods. All methods are related to available operations on the WireMock server endpoints.

import { WireMockRestClient } from 'wiremock-rest-client';

const wireMock = new WireMockRestClient('http://localhost:8080');

const stubMappings = await wireMock.mappings.getAllMappings();

console.log(stubMappings);

await wireMock.global.shutdown();

API

Global

• updateGlobalSettings(delayDefinition: DelayDefinition): Promise<void>
• resetAll(): Promise<void>
• shutdown(): Promise<void>

Example:

await wireMockRestClient.global.resetAll();

Stub mappings

• getAllMappings(): Promise<StubMappings>
• createMapping(stubMapping: StubMapping): Promise<StubMapping>
• createMappingFromFile(fileName: string): Promise<StubMapping>
• createMappingsFromDir(directoryName: string): Promise<any>
• deleteAllMappings(): Promise<void>
• resetAllMappings(): Promise<void>
• getMapping(uuid: string): Promise<StubMapping>
• updateMapping(uuid: string, stubMapping: StubMapping): Promise<StubMapping>
• deleteMapping(uuid: string): Promise<void>
• saveAllMappings(): Promise<void>
• findByMetaData(contentPattern: ContentPattern): Promise<StubMappings>
• removeByMetaData(contentPattern: ContentPattern): Promise<void>

Example:

await wireMockRestClient.mappings.resetAllMappings();

const stubMapping = {
    "request": {
        "method": "GET",
        "urlPathPattern": "/api/helloworld"
    },
    "response": {
        "status": 200,
        "jsonBody": {"hello": "world"},
        "headers": {
            "Content-Type": "application/json"
        }
    }
};

const response = await wireMock.mappings.createMapping(stubMapping);

// Create mapping from current working directory
await wireMock.mappings.createMappingFromFile('stubs/hello-world.json');

// Create mappings from a directory recursively (based on current working directory)
await wireMock.mappings.createMappingsFromDir('stubs');

Recordings

• startRecording(recordSpec: RecordSpec): Promise<void>
• stopRecording(): Promise<StubMappings>
• getRecordingStatus(): Promise<any>
• takeSnapshotRecording(snapshotSpec: RecordSpec): Promise<StubMappings>

Example:

const recordingStatus = wireMockRestClient.recordings.getRecordingStatus();

Requests

• getAllRequests(): Promise<any>
• deleteAllRequests(): Promise<void>
• getRequest(uuid: string): Promise<any>
• deleteRequest(uuid: string): Promise<void>
• resetAllRequests(): Promise<void>
• getCount(requestPattern: RequestPattern): Promise<any>
• removeRequests(requestPattern: RequestPattern): Promise<any>
• removeRequestsByMetadata(contentPattern: ContentPattern): Promise<any>
• findRequests(requestPattern: RequestPattern): Promise<any>
• getUnmatchedRequests(): Promise<any>
• getUnmatchedNearMisses(): Promise<LoggedRequest[]>
• getNearMissesByRequest(loggedRequest: LoggedRequest): Promise<any>
• getNearMissesByRequestPattern(requestPattern: RequestPattern): Promise<any>

Example:

const requests = await wireMockRestClient.requests.getAllRequests();

Scenarios

• getAllScenarios(): Promise<Scenario[]>
• resetAllScenarios(): Promise<void>

Example:

await wireMockRestClient.scenarios.resetAllScenarios();

Configuration

The following optional configuration options are available, to be set via options or environment variables.

Configuration option	Default	Options property	Environment variable
Proxy	No proxy	proxy	WRC_HTTP_PROXY
Headers	No additional headers	headers	WRC_HEADERS
Log level	info	logLevel	WRC_LOG_LEVEL
Continue on failure	false	continueOnFailure	WRC_CONTINUE_ON_FAILURE

Example using options:

const wireMock = new WireMockRestClient('http://localhost:8080', {
    proxy: 'http://mycorporateproxy.com',
    headers: {Authorization: 'some-token'},
    logLevel: 'debug',
    continueOnFailure: true
});

Note: Environment variables have the highest priority

Proxy

The proxy URL can be HTTP or HTTPS. Credentials for authentication can be passed in the URL.

Example:

WRC_HTTP_PROXY=http://username:[e-mail]

Headers

Additional headers can be added to all HTTP requests.

Example:

WRC_HEADERS="{Authorization: 'some-token'}"

Log level

• Default log level is info
• Each log line contains a unique id to trace logs for a single request
• Log level debug will log the request body for each request.

A different log level can be configured by setting the environment variable WRC_LOG_LEVEL to specific a log level (trace/debug/info/warn/error/silent)

Continue on failure

• By default the node process is exited in case of a failure
• To change this behavior to continue on failure, set the value to true

CLI

A small CLI is available to load data from the command line by passing the folder which contains the stub mappings to be loaded. By default it will reset all stub mappings first (configurable).

$ wrc load --help

Usage: wrc load [options]

Options:
  -f, --folders <folders>  Comma separated list of folders containing stub mappings to be loaded
  --no-reset               Skip resetting all stub mappings
  -u, --uri [uri]          WireMock base URI (default: "http://localhost:8080")
  -h, --help               display help for command
