🎯 What

The testing gap addressed: Missing error path testing for MemoryContext::read_content. Previously, only the happy path was tested.

📊 Coverage

What scenarios are now tested:

  • Attempting to read a non-existent source from MemoryContext now asserts that a ServiceError::Execution is returned.
  • Verified the error message contains the expected "Source not found" diagnostic.

✨ Result

The improvement in test coverage: Increased reliability and robustness of the ExecutionContext implementation in the services crate by ensuring failure modes are correctly handled and reported.

Summary by Sourcery

Tests:

  • Add a test ensuring MemoryContext::read_content returns ServiceError::Execution with a 'Source not found' message for missing sources.

This commit adds a unit test to verify that `MemoryContext::read_content`
correctly returns a `ServiceError::Execution` error when attempting to
read a source that does not exist in the context.

The test ensures that the error variant is correct and that the error
message contains the expected diagnostic information.

Hey - I've left some high level feedback:

  • In test_memory_context_read_content_error, you can simplify the error assertion by using let err = result.expect_err("expected error when reading missing source"); and matches! or if let ServiceError::Execution { message } = err { ... } else { panic!(...) } instead of assert!(result.is_err()) followed by match result.unwrap_err().
