Unit Test Cases

[vindwi]

We should include unit test cases at least for key features.

Hi , I’d like to work on this.
Could a maintainer please assign it to me and confirm the points?

I will start with easy unit tests that are currently missing:

• TextEmbedder invalid dimension handling
• Embedding output dimension correctness
• Empty-input embedding behavior
• Case/punctuation normalization in embedding
• Settings default-value initialization

Then I can extend coverage to pipeline/client behavior in follow-up tests.
