+ROOST_METHOD_SIG_HASH=generateContent_c08b9769fe
+
+Scenario 1: Builds messages from text-only contents and invokes Anthropic once
+
+Details:
+ TestName: buildsMessageParamsFromTextOnlyContents
+ Description: Verifies that when LlmRequest contains Content instances with only text Part(s), the method maps them into Anthropic MessageParam(s), builds MessageCreateParams correctly, calls anthropicClient.messages().create exactly once, and returns a Flowable that emits exactly one LlmResponse.
+
+Execution:
+ Arrange: Create an LlmRequest with a non-empty contents() list where each Content has role "user" and parts containing text only. Mock anthropicClient.messages().create to return a valid Message with a simple text ContentBlock.
+ Act: Call generateContent with stream=false.
+ Assert: Capture the MessageCreateParams passed to anthropicClient.messages().create and assert that:
+ - messages contains entries equal in count to LlmRequest.contents().
+ - each MessageParam contains text blocks reflecting the corresponding input text parts.
+ - the Flowable emits exactly one LlmResponse and completes.
+Validation:
+ Confirms that text parts are correctly propagated to Anthropic as text message blocks and that the method performs a single, synchronous Anthropic call, then wraps the converted response in a single-emission Flowable.
