我正在编写一个异步测试,期望异步函数像这样抛出:
it("expects to have failed", async () => {
let getBadResults = async () => {
await failingAsyncTest()
}
expect(await getBadResults()).toThrow()
})
但是开玩笑只是失败而未通过测试:
FAIL src/failing-test.spec.js
● expects to have failed
Failed: I should fail!
如果我将测试重写为如下所示:
expect(async () => {
await failingAsyncTest()
}).toThrow()
我收到此错误,而不是通过测试:
expect(function).toThrow(undefined)
Expected the function to throw an error.
But it didn't throw anything.
