我们如何以编程方式清除 jasmine 测试套件中的间谍?谢谢.
How do we clear the spy in a jasmine test suite programmatically? Thanks.
beforeEach(function() {
spyOn($, "ajax").andCallFake(function(params){
})
})
it("should do something", function() {
//I want to override the spy on ajax here and do it a little differently
})
推荐答案
我不确定这是否是个好主意，但您可以简单地将函数上的 isSpy 标志设置为 false:
I'm not sure if its a good idea but you can simply set the isSpy flag on the function to false:
describe('test', function() {
var a = {b: function() {
}};
beforeEach(function() {
spyOn(a, 'b').andCallFake(function(params) {
return 'spy1';
})
})
it('should return spy1', function() {
expect(a.b()).toEqual('spy1');
})
it('should return spy2', function() {
a.b.isSpy = false;
spyOn(a, 'b').andCallFake(function(params) {
return 'spy2';
})
expect(a.b()).toEqual('spy2');
})
})
但是，如果您需要间谍的其他行为，则为这种情况创建一个新套件可能是一个更好的主意.
But maybe its a better idea to create a new suite for this case where you need an other behavior from your spy.
