One post tagged with "test"

In my Quarkus application, I encountered a hiccup with the Panache ORM while implementing and testing a REST service. Specifically, I faced a test failure related to the automatic update of a specifications list after deleting an element from the JSON/Entity. In this blog post, I'll walk you through the issue and demonstrate how GitHub Copilot came to the rescue, streamlining the implementation of a solution.

The Challenge:

The JSON schema for my REST service looked like this:

{
    "id": 1,
    "name": "Fanatic Falcon",
    "description": "Slalom board",
    "specifications" : [
        {"id": 10, "name": "Falcom 100", "volume": 100},
        {"id": 11, "name": "Falcom 110", "volume": 110},
        {"id": 12, "name": "Falcom 120", "volume": 120} 
    ]
    ```
}

I had a test verifying the number of specifications after the deletion of one of them. However, the Panache ORM didn't automatically update the specifications list after deletion, leading to a failing test.

The Solution:

To address this issue, I needed to implement business logic to delete specifications in the database that were not present in the JSON payload. I documented the logic in a comment and collaborated with GitHub Copilot to generate the code.

Here's a snippet of the code:

...

// if the number of specifications in the existing board is different than the number of specifications in the updated board
// it means that some specifications have been removed, so we need to delete them
// for this we meed to loop on existing specifications and see if they are in the updated board
// if they are not add them to a list of specs to delete
// then use removeAll on existing board specifications
List<BoardSpecification> specsToDelete = new ArrayList<>();
for (BoardSpecification existingSpec : existingBoard.specifications) {
    boolean found = false;
    for (BoardSpecification spec : board.specifications) {
        if (existingSpec.id.equals(spec.id)) {
            found = true;
        }
    }
    if (!found) {
        specsToDelete.add(existingSpec);
    }
}
existingBoard.specifications.removeAll(specsToDelete);
existingBoard.persist();
