[NxDataDisplayHarness] Issues when having a data display with and without a label on the same page

[Dominik-Kriese]

Reproduction Link

As one needs to run tests for the problem to occur, I created a little repository for the reproduction. I hope this is fine as well. https://github.com/Dominik-Kriese/ng-aquilla-test-repo

Steps to reproduce:

1. Open the app.component.spec.ts
2. Have a look at the test titled 'does not work by label even if the label is correct'.

📗 Expected Behavior

This test should find the according nx data display.

📕 Actual Behavior

The harness errors as there is a nx data display present without a label

📦 Environment

• Aquila/NDBX version: 17.6.0
• Angular/CDK version: 17.3.0
• Operating System & version (desktop or mobile): MacOS

Current information:

I took a look into it and it seems to be this file that creates the issue:

    // projects/ng-aquila/src/data-display/testing/data-display-harness.ts
    async getLabel(): Promise<string> {
        return (await this._getLabel()).text();
    }

I would propose the following change, which ensures, that a non present label is interpreted as undefined:

    // projects/ng-aquila/src/data-display/testing/data-display-harness.ts
    async getLabel(): Promise<string> {
        return (await this._getLabel()).text().catch(() => undefined);
    }

If that is a valid solution, I could provide a pull request.

Best Regards and thanks in advance.

I talked to a colleague of mine and will port this issue to the internal repositories. Sorry for the wrong place to post this.
