而且我想监视$scope.addLeftRange(),所以当$scope.addRangesAndSquare被调用时是这样的$scope.addLeftRange():
it('expect addLeftRange to be called after calling addRangesAndSquare', function () {
spyOn(scope ,'addRangesAndSquare');
spyOn(scope, 'addLeftRange');
scope.addRangesAndSquare();
expect(scope.addLeftRange).toHaveBeenCalled();
});

我更改了通过时间间隔呈现的组件。
我希望能够在每次发生变化时添加动画。最好的方法是什么?
constructor (props) {
super(props)
this.state = { currentComponent: 1,
numberOfComponents: 2}
}
componentWillMount() {
setInterval(() => {
if(this.state.currentComponent === 2) {
this.setState({currentComponent: 1})
} else {
this.setState({currentComponent: this.state.currentComponent + 1})
}
}, 5000)
}
render(){
let currentComponent = null;
if(this.state.currentComponent === 1) {
currentComponent = <ComponentOne/>;
} else {
currentComponent = <ComponentTwo/>;
}
return(
currentComponent
)
}
