@copilot , we can do better. Let's add more tests: For notification/notifications.directive.ts the isVisible property 's set is not covered. Looks like a decent unit test to add. For drag-drop.directive.ts we can add some tests that use touch-prefixed events as they are handled under the hood. mouseDown too. Check when these are bound to in the ngAfterContentInit step and ensure a correct environment for the events to be handled. The For month-picker.component.ts - add tests for changing the active view's decade . Unit test getNextYear/getPreviousYear. handlePageDown/Up are not covered either. Also the handlers for onHome and onEnd lack coverage. |

Pull request overview
This PR primarily increases unit test coverage across multiple Ignite UI for Angular components/directives and addresses a flaky PDF exporter spec setup, with an additional package-lock.json update that changes resolved dependency versions.
Changes:
- Added new/expanded unit tests for snackbar notifications visibility, navigation drawer gestures, pivot grid header navigation, tree grid group-by area, drag-drop edge cases, mask composition input handling, month-picker keyboard navigation, and pinned-row primary key editing.
- Stabilized
pdf-exporter.spec.tsby guardingconsole.warnspying in parallel Karma runs. - Updated
package-lock.json(multiple dependency version/resolution changes).

This promise-based test swallows failures by calling done() in .catch(...), so a rejection won’t fail the spec. Pass the error through (e.g. done.fail(err) / done(err)) or return the promise instead of using done.

This .catch(() => done()) swallows promise rejections and can mark failing gesture simulations as passing. Use done.fail(err)/done(err) or return the promise chain.

This .catch(() => done()) swallows errors and can cause false positives. Prefer returning the promise from the spec or pass the error to done.fail.

headerRow is declared but never used in this new test block. With the repo’s ESLint config, this will at least generate a @typescript-eslint/no-unused-vars warning (and may fail CI if warnings are treated as errors). Remove it or prefix with _ if it’s intentionally unused.

initialSortDirection is declared but never used, which triggers the repo’s unused-vars lint rule. Remove it (or assert on it if you intended to validate sort direction changes).

These promise-based tests swallow failures by calling done() inside .catch(...), which can make the test pass even when the swipe/pan helper rejects or an assertion throws. Pass the error to Jasmine instead (e.g. done.fail(err) / done(err)), or return/await the promise rather than using done.

This .catch(() => done()) pattern hides errors and can produce false-positive passing tests. Please propagate the error to Jasmine (done.fail) or return the promise chain.

This .catch(() => done()) pattern suppresses failures; if pan(...) rejects the test will still pass. Please propagate the rejection (e.g. done.fail(err)) or return the promise.

This test uses nested setTimeout(..., 50) delays to wait for MutationObserver callbacks. That adds ~100ms wall-clock time and can be flaky under load. Consider using fakeAsync + flushMicrotasks() / tick(0) to deterministically flush the observer microtask queue instead of real timers.

Test name says “forward by 15 years via Shift+PageDown”, but the assertion (and implementation) advances by 1 year in the default/year view when Shift is held. Rename the spec to match the actual behavior being tested to avoid confusion.
