Feature: llama.cpp server
|
|
|
|
Background: Server startup
|
|
Given a server listening on localhost:8080
|
|
And a model file tinyllamas/stories260K.gguf from HF repo ggml-org/models
|
|
And a model file test-model.gguf
|
|
And a model alias tinyllama-2
|
|
And BOS token is 1
|
|
And 42 as server seed
|
|
And 256 KV cache size
|
|
And 32 as batch size
|
|
And 2 slots
|
|
|
|
Scenario: Inference with context shift
|
|
And 64 server max tokens to predict
|
|
Then the server is starting
|
|
Then the server is healthy
|
|
Given a prompt:
|
|

And a completion request with no api error
|
|
Then 64 tokens are predicted matching fun|Annaks|popcorns|pictry|bowl
|
|
And the completion is truncated
|
|
And 109 prompt tokens are processed
|
|
|
|
Scenario Outline: Inference without context shift
|
|
And <n_predict> server max tokens to predict
|
|
And disable context shifting
|
|
Then the server is starting
|
|
Then the server is healthy
|

"""
|
|
Hi how are you

|
And a completion request with no api error
|
