我是单元测试用例的新手。我被困在编写如下所述的AWS Cognito服务的单元测试用例中。

下面是代码。

signUp(userData) 

{

return new Promise((resolved, reject) => {

  const userPoolData = new AWSCognito.CognitoUserPool(this._POOL_DATA);

  let userAttribute = [];

  userAttribute.push(

    new AWSCognito.CognitoUserAttribute({ Name: "email", Value: userData.email }),

    new AWSCognito.CognitoUserAttribute({ Name: "custom:role", Value: userData.role }),

  );

  userPoolData.signUp(userData.email, userData.password, userAttribute, null, function (err, result)

  {

    if (err) {

      reject(err);

    } 
    else {

      resolved(result);

    }
  });
});
}

import * as AWS from 'the-dependency'; // dependency where AWSCognito comes from

it('should sign up user', async done => {
  // CognitoUserPool return this
  spyOn(AWS.AWSCognito, 'CognitoUserPool').and.returnValue({
    signUp: (email, password, userAttribute, fn) => fn(null, true); // may have to check the mock
});;
  const result = await component.signUp({ email: '...', password: '...', role: '...' });
  // wait until pending promises are done
  await fixture.whenStable();
  expect(result).toBe(true); // resolved it to true in `signUp` mock
});
