问题描述
我已经开始为Angular编写测试用例,并且在阅读来自互联网的文章时,我发现我们可以使用不同的方法来配置TestBed
。以下是一些示例:
示例1:
beforeEach(async(() => {
TestBed.configureTestingModule({
...
}).compileComponents()
.then(() => {
fixture = TestBed.createComponent(Component);
component = fixture.componentInstance;
fixture.detectChanges();
});
}));
示例2:
beforeEach(async(() => {
TestBed.configureTestingModule({
...
}).compileComponents();
}));
beforeEach(() => {
fixture = TestBed.createComponent(Component);
component = fixture.componentInstance;
fixture.detectChanges();
});
示例3:
beforeEach(async(() => {
TestBed.configureTestingModule({
...
}).compileComponents();
fixture = TestBed.createComponent(Component);
component = fixture.componentInstance;
fixture.detectChanges();
}));
示例4:
beforeEach(async() => {
TestBed.configureTestingModule({
...
});
await TestBed.compileComponents();
fixture = TestBed.createComponent(Component);
component = fixture.componentInstance;
fixture.detectChanges();
});
我需要帮助以了解建议采用哪种方法?
