Automatic Review

The provided code diff has a few issues that need to be addressed:

Bugs:

• The use of t.Context() instead of context.Background() in the test functions is incorrect. The method t.Context() is not a standard method for the testing package in Go (unless t is a type that implements such a method, which is not indicated here). The correct approach in the context of Go's testing framework is to use context.Background().

Suggestion:
Replace the calls to t.Context() with context.Background() to avoid any potential runtime errors or unexpected behavior.

Updated lines:

-	res, err := c.Chat(t.Context(), param)
+	res, err := c.Chat(context.Background(), param)

-	_, err = c.Chat(t.Context(), param)
+	_, err = c.Chat(context.Background(), param)

By making this change, you ensure that the tests execute correctly with a proper context, maintaining the intended behavior of the tests.
