Javascript 如何使用jasmine在setTimeout中测试spy?
我有这样的代码:Javascript 如何使用jasmine在setTimeout中测试spy?,javascript,jasmine,Javascript,Jasmine,我有这样的代码: it('should call json-rpc', function() { var spy = spyOn(object, 'echo'); if (spy.andCallThrough) { spy.andCallThrough(); } else { spy.and.callThrough(); } enter(term, 'echo foo bar'); setTimeout(functi
it('should call json-rpc', function() {
var spy = spyOn(object, 'echo');
if (spy.andCallThrough) {
spy.andCallThrough();
} else {
spy.and.callThrough();
}
enter(term, 'echo foo bar');
setTimeout(function() {
// here I've got error Expected a spy, but got Function.
expect(object.echo).toHaveBeenCalledWith('foo', 'bar');
term.destroy().remove();
}, 200);
});
我有一个错误,object.echo不是间谍而是函数,我如何检查函数是否在setTimeout中被调用
编辑:我已尝试使用此选项:
if (jasmine.Clock) {
jasmine.Clock.useMock();
} else {
jasmine.clock().install();
}
及
但这也不起作用。我有错误
Expected spy echo to have been called with [ 'foo', 'bar' ] but it was never called.
期望值应该在spy的本地JavaScript局部变量实例上。因此,在您的情况下,您应该使用:
expect(spy).toHaveBeenCalledWith
我想你还得告诉jasmine测试是在
设置超时后完成的。例如,对于jasmine 2.0类似的内容(参见jasmine 1.3及更多内容的链接)
您可以使用“完成”测试回调:
it('should call json-rpc', function(done) {
var spy = spyOn(object, 'echo');
if (spy.andCallThrough) {
spy.andCallThrough();
} else {
spy.and.callThrough();
}
enter(term, 'echo foo bar');
setTimeout(function() {
// here I've got error Expected a spy, but got Function.
expect(object.echo).toHaveBeenCalledWith('foo', 'bar');
term.destroy().remove();
done();
}, 200);
});
此处显示:我认为期望值应该是spy的局部变量,您将其称为spy,因此:expect(spy)。toHaveBeenCalledWith
。你试过了吗?@hightempo是的,它可以工作,你可以把这个作为一个答案。与
一起调用。你不应该给matcher打电话吗?@alecxe-是的,我只是发布了部分代码,@jcubic需要更改才能工作。整行应该是expect(spy).toHaveBeenCalledWith('foo','bar')代码>一对夫妇的建议,考虑使用$TimeOutt并调用它作为OSESSET到StudiTimeOut.此外,您还可以添加afterEach()函数来执行以下操作:term.destroy().remove();
it('should call json-rpc', function(done) {
var spy = spyOn(object, 'echo');
if (spy.andCallThrough) {
spy.andCallThrough();
} else {
spy.and.callThrough();
}
enter(term, 'echo foo bar');
setTimeout(function() {
// here I've got error Expected a spy, but got Function.
expect(object.echo).toHaveBeenCalledWith('foo', 'bar');
term.destroy().remove();
done();
}, 200);
});
