Increase test coverage

[vmesel]

We need to add testing for LCEL, Abstract and Default LLMs and the API parts of the code.

Right now we have the following coverage:

Hi @vmesel
Are you still intested in this issue? I was thinking that I could help with that.

[vmesel]

Hey @alexfilothodoros, yes! We are interested!

[alexfilothodoros]

Awesome! I will try to set up everything during the weekend and start working on it :)
