我正在使用create-react-app并尝试编写一个检查console.log输出的jest测试
我的测试功能是:
export const log = logMsg => console.log(logMsg);
我的测试是:
it('console.log the text "hello"', () => {
console.log = jest.fn('hello');
expect(logMsg).toBe('hello');
});
这是我的错误
FAIL src/utils/general.test.js
? console.log the text hello
expect(received).toBe(expected) Expected value to be (using ===): "hello"
Received:
undefined
Difference:
Comparing two different types of values. Expected string but received undefined.
