# Test plan:
|
||||
#
|
||||
# Types of input:
|
||||
# - array of a string
|
||||
# - array of a image (ImageContentItem, either URL or base64 string)
|
||||
# - array of a text (TextContentItem)
|
||||
# Types of output:
|
||||
# - list of list of floats
|
||||
# Params:
|
||||
# - text_truncation
|
||||
# - absent w/ long text -> error
|
||||
# - none w/ long text -> error
|
||||
# - absent w/ short text -> ok
|
||||
# - none w/ short text -> ok
|
||||
# - end w/ long text -> ok
|
||||
# - end w/ short text -> ok
|
||||
# - start w/ long text -> ok
|
||||
# - start w/ short text -> ok
|
||||
# - output_dimension
|
||||
# - response dimension matches
|
||||
# - task_type, only for asymmetric models
|
||||
# - query embedding != passage embedding
|
||||
# Negative:
|
||||
# - long string
|
||||
# - long text
|
||||
#
|
||||
# Todo:
|
||||
# - negative tests
|
||||
# - empty
|
||||
# - empty list
|
||||
# - empty string
|
||||
# - empty text
|
||||
# - empty image
|
||||
# - long
|
||||
# - large image
|
||||
# - appropriate combinations
|
||||
# - batch size
|
||||
# - many inputs
|
||||
# - invalid
|
||||
# - invalid URL
|
||||
# - invalid base64
|
||||
#
|
||||
# Notes:
|
||||
# - use llama_stack_client fixture
|
||||
# - use pytest.mark.parametrize when possible
|
||||
# - no accuracy tests: only check the type of output, not the content
