Jasmine calls.length and callCount are undefined
提问by Dru
I'm trying to test my chrome extension with Jasminebut I'm having trouble getting calls.lengthand callCountto behave as expected. Both cases return undefined.
我想测试我的浏览器扩展程序与茉莉，但我遇到了麻烦calls.length，并callCount表现为预期的。两种情况都返回undefined。
I've included a sample of the code and the spec. Here's the rest of the code if it helps: https://github.com/DruRly/kamikaze/tree/closeIdleTab
我已经包含了代码和规范的示例。如果有帮助，这里是其余的代码：https: //github.com/DruRly/kamikaze/tree/closeIdleTab
How to reproduce:

it("calls closeIdleTab for each tab received", function(){
spyOn(kamikaze, 'closeIdleTab');
kamikaze.closeIdleTabs([1,2,3]);
expect(kamikaze.closeIdleTab.calls.length).toBe(3);

The Jasmine APIs have changed a bit in the 2.x version "series".
According to the latest docsyou should use the count()method:
Jasmine API 在 2.x 版本“系列”中发生了一些变化。
根据最新的文档，您应该使用该count()方法：
expect(kamikaze.closeIdleTab.calls.count()).toBe(3);
I also tried that with your code and all tests pass successfully.
我也用你的代码尝试过，所有测试都成功通过。

Alternative syntax (with a bit nicer output on failure) would be
替代语法（失败时输出更好）将是
expect(kamikaze.closeIdleTab).toHaveBeenCalledTimes(3);
