当我期望抛出时，摩卡通过测试，但 muy 函数没有抛出

Question

我有一个我希望抛出错误的函数，但如果它没有抛出它，那么 mocha 就通过了测试。

async function throwError() {
   throw new Error("foo");
}
async function notThrowError() {
   
}

测试：

describe("bar", function(){
  it("bar-2", async function() {
     await expect(throwError()).throw //passes the test
})
}

describe("bar", function(){
  it("bar-2", async function() {
     await expect(notThrowError()).throw //passes the test, but no error has been thrown 
})
}

Answer 1

我应该使用chai as promised

const chaiAsPromised = require('chai-as-promised');
chai.use(chaiAsPromised);
chai.should();

describe("bar", function(){
   it("bar-2", async function() {
      return notThrowError().should.eventually.rejected; //do not pass the test if not throw an error
   })
}

当我期望抛出时，摩卡通过测试，但 muy 函数没有抛出

Mocha passing test when i expect throw, but muy function is not throwing

javascript

mocha.js

node.js

chai
