我目前正在Angular 7中测试一个角度应用程序,但我不知道如何测试Submit函数的此分支,在此组件中大约有20多个测试,其中一些甚至使用相同的服务间谍作为无法正常工作的测试:
分支:
submit(): void {
if (this.systemTable) {
// this.formArray = this.formBuilder.array([]);
while (this.formArray.length) {
this.formArray.removeAt(0);
console.log('dfdfdf');
} //this.formArray.removeAt(0);
} //...
我的测试:
it('submit() should remove when systemTable is true', () => {
app.ngOnInit();
app.systemTable = true; //Entering the branch i wan't to test
const f = app.formArray;
app.addRow(); //This function adds a row into the app.formRow, I checked it's values with a debugger and it's working
const userServiceSpy = spyOn(app.formArray, 'removeAt');
app.submit();
expect(userServiceSpy).toHaveBeenCalledTimes(1);
});
答案 0 :(得分:0)
将循环从while更改为for,在角度8中将不再需要该循环。
