Overview

Package fakelinstor provides an in-memory HTTP test double for the LINSTOR REST API. It implements a subset of the API against which a client.Client can be pointed, so applications can exercise their LINSTOR interactions in tests without a running LINSTOR controller.

All state is kept in memory. The following client calls are supported:

• Controller: GetVersion (reports a static fake version)
• Nodes: Create, GetAll, Get, Delete, Evacuate, Restore, Lost
• Node storage pools: GetStoragePools, GetStoragePool, CreateStoragePool, ModifyStoragePool, DeleteStoragePool
• Node physical storage: CreateDevicePool
• ResourceGroups: Create, GetAll
• ResourceDefinitions: Create, GetAll (optionally with volume definitions), Delete, Truncate, CreateVolumeDefinition, GetVolumeDefinitions, ModifyVolumeDefinition
• Resources: Create, Get, GetAll, GetResourceView

Any endpoint not listed above responds with 501 Not Implemented rather than 404, so an unimplemented call is not mistaken for a genuine github.com/LINBIT/golinstor/client.NotFoundError.

FakeLinstor additionally exposes the test-only helpers StoragePools and DevicePoolCreations for assertions, and SetConnectionStatus to simulate node connectivity changes.

	// contains filtered or unexported fields
}

func New

func New() *FakeLinstor

func (*FakeLinstor) DevicePoolCreations

func (f *FakeLinstor) DevicePoolCreations() int

DevicePoolCreations returns how many times CreateDevicePool was called, for assertions in tests.
