fake

Overview ¶

Package fake provides a fake BinaryStore implementation for tests of components and runtimes that consume a binary store. It is not a user-facing component and so it does not ship component metadata.

Following the convention used elsewhere in Dapr, Fake holds one function field per interface method and exposes a WithXxx builder for each, so a test can make an individual operation fail on demand:

store := fake.New().WithGet(func(context.Context, *binarystore.GetRequest) (*binarystore.GetResponse, error) {
	return nil, errors.New("boom")
})

Every field defaults to the in-memory binary store, so a Fake that overrides nothing behaves like a real store while holding all data in process memory. That makes it usable both for wiring tests that just need a working store and for exercising a consumer's error handling.

NewFake is the registry-shaped constructor, taking a logger and returning binarystore.BinaryStore, so the fake can be registered as a component in the same way as a real binary store.
