Angular 15 无法将 checked 属性设置为 mat-checkbox 它测试规范

Question

出于某种原因，我无法在测试中为我的 mat-checkbox 设置 checked 道具。不知道这里可能是什么问题

html

<form class="example-form">
    <mat-checkbox [checked]="localValue" [disabled]="disabled" (click)="sendCheck()"></mat-checkbox>
</form>

ts

    localValue!: boolean
    ngOnInit(): void {
        this.localValue = this.value ? this.value === 'true' : false
    }

    sendCheck() {
        this.localValue = !this.localValue
        this.cellValueChanged.emit(this.localValue)
    }

spec.ts

function createComponent<T>(componentType: Type<T>, extraDeclarations: any[] = []) {
            TestBed.configureTestingModule({
                imports: [MatCheckboxModule, FormsModule, ReactiveFormsModule],
                declarations: [componentType, ...extraDeclarations],
            }).compileComponents();

            return TestBed.createComponent<T>(componentType);
        }
        let loader: HarnessLoader
        let checkBoxHarness: MatCheckboxHarness
        let checkboxDebugElement: DebugElement
        let checkboxNativeElement: HTMLElement
        let checkboxInstance: MatCheckbox
        let inputElement: HTMLInputElement
        TestBed.resetTestEnvironment()
        TestBed.initTestEnvironment(BrowserDynamicTestingModule, platformBrowserDynamicTesting())
        let component: BooleanComponent
        let fixture: ComponentFixture<BooleanComponent>
        beforeEach(async () => {
            fixture = createComponent(BooleanComponent, [CellComponent])
            component = fixture.debugElement.componentInstance
            loader = TestbedHarnessEnvironment.loader(fixture)
            checkBoxHarness = await loader.getHarness(MatCheckboxHarness)
            checkboxDebugElement = fixture.debugElement.query(By.directive(MatCheckbox))!
            checkboxNativeElement = checkboxDebugElement.nativeElement
            checkboxInstance = checkboxDebugElement.componentInstance
            inputElement = <HTMLInputElement>checkboxNativeElement.querySelector('input')
        })
        it('check', fakeAsync(() => {
            component.field = {
                guid: '',
                field_type_code: '',
                operationCode: { multiple: true },
            }
            expect(checkboxInstance.checked).toBe(false)
            expect(inputElement.checked).toBe(false)
            component.localValue = true
            fixture.detectChanges()
            console.log(component.localValue)
            console.log(checkboxInstance.checked)
            console.log(inputElement.checked)
            expect(checkboxInstance.checked).toBe(true)
            inputElement.click()
            fixture.detectChanges()
            flush()
            console.log(checkboxInstance.checked)
            expect(checkboxInstance.checked).toBe(false)
        }))

我尝试过基本上设置属性，该属性必须检查为真，但它没有改变任何东西。还尝试将 FormControl 和 ngModel 与 standalone 一起使用，但情况更糟。
