What is the current behavior?

When using nz-result with only nzStatus set (e.g., nzStatus="success"), no icon is displayed. The icon() computed property only checked nzIcon input and returned undefined when not provided.

Issue Number: #9015

What is the new behavior?

Default icons now display based on nzStatus when nzIcon is not provided:

• success → check-circle
• error → close-circle
• info → exclamation-circle
• warning → warning

Content projection via [nz-result-icon] directive still works when provided.

Changes:

• Use ng-content fallback content to render the default icon when no custom [nz-result-icon] is projected
• Added defaultIcon() computed property to get the icon from IconMap based on nzStatus

<!-- This now correctly shows the success icon -->
<nz-result nzStatus="success" nzTitle="Successfully Purchased!" />

Does this PR introduce a breaking change?

• Yes
• No

Other information

Added 4 test cases verifying default icon display for each status type.

@copilot Do not use contentChild to determine if customIconDirective exists; instead, use the fallback content of <ng-content select="[nz-result-icon]"></ng-content> to render the default icon.

@copilot Do not use contentChild to determine if customIconDirective exists; instead, use the fallback content of <ng-content select="[nz-result-icon]"></ng-content> to render the default icon.

Refactored to use ng-content fallback content instead of contentChild. The default icon is now rendered as fallback when no custom [nz-result-icon] is projected. Commit: 0fc4735

Pull request overview

This PR fixes a bug where the nz-result component didn't display default icons when only nzStatus was set without providing a custom nzIcon. The fix uses ng-content fallback to render default status-based icons.

Key Changes:

• Added defaultIcon() computed property to map status to default icon names
• Modified template to include fallback content in ng-content that renders the default icon
• Added comprehensive test coverage for all four status types (success, error, info, warning)

Reviewed changes
