[英]Trying to expect a call to a function inside an anonymous function with JEST
[英]Jest - [Function anonymous] in expect
Jest 期望预期的Cell
属性值为[Function anonymous]
。
什么是正确的语法?
() => {}
似乎是[Function Cell]
因此测试失败。
const expected =
[{ Cell: () => {}, Header: '', accessor: () => {}, disableSortBy: true, id: 18, width: 50 }];
expect(result).toBe(expected);
安慰:
$ jest test
----

Array [

"Header": "",
"accessor": [Function accessor],
"disableSortBy": true,
"id": 18,
"width": 50,
您需要说明它需要数组,然后是对象。 每个对象都需要指定其类型或值
尝试这样的事情
const expected = expect.arrayContaining([
expect.objectContaining({
Cell: expect.any(Function),
Header: expect.any(String),
accessor: expect.any(Function),
disableSortBy: expect.any(Boolean),
/*...........so..on............*/
})
]);
expect(result).toEqual(expected);
