Я тестирую компонент, который использует пользовательскую директиву (похожую на ngIf).Я издевался над дочерним компонентом, но получаю следующую ошибку:
"message": "An error was thrown in afterAll\nTypeError: Cannot read property 'workInProgressFlag' of undefined\nerror properties: Object({ ngDebugContext: DebugContext_({ view: Object({ def: Object({ factory: Function, nodeFlags: 16793601, rootNodeFlags: 1, nodeMatchedQueries: 0, flags: 0, nodes: [ Object({ nodeIndex: 0, parent: null, renderParent: null, bindingIndex: 0, outputIndex: 0, checkIndex: 0, flags: 1, childFlags: 16793601, directChildFlags: 1, childMatchedQueries: 0, matchedQueries: Object({ }), matchedQueryIds: 0, references: Object({ }), ngContentIndex: null, childCount: 4, bindings: [ ], bindingFlags: 0, outputs: [ ], element: Object({ ns: '', name: 'div', attrs: [ Array ], template: null, componentProvider: null, componentView: null, componentRendererType: null, publicProviders: null({ }), allProviders: null({ }), handleEvent: Function }), provider: null, text: null, query: null, ngContent: null }), Object({ nodeIndex: 1, parent: Object({ nodeIndex: 0, parent: null, renderParent: null, bindingIndex: 0, outputIndex: 0, checkIndex: 0, flags: 1, childFlags: 16793601, directChildFlags: 1, chil ...\n at <Jasmine>\n at WorkInProgressFlagDirective.displayElement (webpack:///./src/app/shared/directives/work-in-progress-flag.directive.ts?:35:42)\n at WorkInProgressFlagDirective.set [as flagName] (webpack:///./src/app/shared/directives/work-in-progress-flag.directive.ts?:24:22)\n at updateProp (webpack:///./node_modules/@angular/core/fesm5/core.js?:10575:37)\n at checkAndUpdateDirectiveInline (webpack:///./node_modules/@angular/core/fesm5/core.js?:10326:19)\n at checkAndUpdateNodeInline (webpack:///./node_modules/@angular/core/fesm5/core.js?:11635:20)\n at checkAndUpdateNode (webpack:///./node_modules/@angular/core/fesm5/core.js?:11597:16)\n at debugCheckAndUpdateNode (webpack:///./node_modules/@angular/core/fesm5/core.js?:12234:38)\n

Вот как я его настраиваю:
TestBed.configureTestingModule({
declarations: [
PageActionsComponent,
MockComponent({ selector: 'print', template: '<p>print</p>' }),
WorkInProgressFlagDirective,
],
providers: [
{ provide: ConfigService, useValue: getMockConfigService },
{ provide: TranslationService, useValue: getStubTranslationService({ 'print': 'printText' }) },
]
}).compileComponents();
fixture = TestBed.createComponent(PageActionsComponent);
fixture.detectChanges();
Компонент вТест выглядит следующим образом: директива
<ul>
<li>
<print *workInProgressFlag="'print'"></print>
</li>
</ul>
*workInProgressFlag
очень похожа на *ngIf
Печать и тестируемый компонент не имеют @input
и @output
.
Я пытался насмехаться над workInProgressFlag
, но результат тот же.
