Description

I am testing my crew with 3 agents and I have a PDFKnowledgeSource defined.

When running 'crewai test' I get this error.

Steps to Reproduce

I am testing my crew with 3 agents and I have a PDFKnowledgeSource defined.

from licenseproai.tools.pdf_knowledge_source import PDFKnowledgeSource

Knowledge base

pdf_source = PDFKnowledgeSource(file_paths=["cnmi.pdf"])

@agent
def researcher(self) -> Agent:
	return Agent(
		config=self.agents_config['researcher'],
		tools=[self.search_tool],
		verbose=True,
		knowledge_sources=[pdf_source],
		llm=self.llm
	)

When running 'crewai test' I get this error: Exception: An error occurred while testing the crew: Can't instantiate abstract class BaseKnowledgeSource without an implementation for abstract methods 'add', 'validate_content'.

I have used both the standard import and also imported the PDFKnowledgeSource file under my project without making any changes to it.
I get the same error in both cases.

Expected behavior

PDFKnowledgeSource should work properly, as per the documentation.
