22-31: Well-structured stub initialization!
The consolidation of Kafka consumer stubs into a single consumerStub object is a great improvement. This approach:
- Provides better organization of related stubs
- Makes the test setup more maintainable
- Accurately represents the actual Kafka consumer interface
129-146: Excellent subscription order verification!
This test effectively ensures the correct initialization sequence of the Kafka consumer by:
- Verifying all topics are subscribed to before the consumer starts
- Using Promise resolution to control the timing
- Checking the correct order of operations

🛠️ Refactor suggestion
Enhance message handling verification
While the test structure is good, it could benefit from more specific assertions to verify the actual message processing logic.
Consider adding these verifications:
it("should handle messages for each topic correctly", async () => {
// Simulate message processing by triggering the eachMessage callback
consumerStub.run.callsFake(async ({ eachMessage }) => {
await eachMessage({
topic: "ip-address",
partition: 0,
message: { value: JSON.stringify({ ip: "192.168.1.1" }) },
});
});
await kafkaConsumer();
// Verify message processing
expect(consumerStub.run.calledOnce).to.be.true;
+ // Verify the message was processed correctly
+ expect(loggerInfoStub.calledWith(
+ sinon.match(/Processing message from topic: ip-address/)
+ )).to.be.true;
+ // Verify any specific handlers or transformations
+ // Add assertions for business logic specific to ip-address topic

🛠️ Refactor suggestion
Strengthen error handling test assertions
The current test only verifies that an error was logged, but doesn't validate the specific error handling behavior.
Consider enhancing the test with more specific assertions:
it("should handle message processing errors", async () => {
+ const invalidJson = "invalid-json";
consumerStub.run.callsFake(async ({ eachMessage }) => {
await eachMessage({
topic: "ip-address",
partition: 0,
- message: { value: "invalid-json" },
+ message: { value: invalidJson },
});
});
await kafkaConsumer();
- expect(loggerErrorStub.called).to.be.true;
+ expect(loggerErrorStub.calledWith(
+ sinon.match(/Error processing message from topic: ip-address/)
+ )).to.be.true;
+ expect(jsonrepairStub.calledWith(invalidJson)).to.be.true;
+ // Verify that the consumer continues processing after error
+ expect(consumerStub.run.called).to.be.true;
});Committable suggestion skipped: line range outside the PR's diff.
