amazon-web-services - AWS CDK 单元测试失败 - jest ts

Question

我在创建 IAM 角色的 Typescript 中创建了一个 AWS CDK 应用程序。这是我的代码:

export class AccountCreatorIamRoleStack extends cdk.Stack {
    public create(): iam.Role {
        const iamRole = some logic to create iam role goes here;
        return iamRole;
    }
}

我已经通过创建一个像这样的 IAM 角色确认此代码有效:

var roleCreator = new AccountCreatorIamRoleStack(app, 'AccountCreatorIamRoleStack');
roleCreator.create();

但是，当我运行这个 Jest 单元测试时:

test('Test IAM Role Created', () => {
  const app = new cdk.App();
  // WHEN
  var stack = new AccountCreatorIamRoleStack(app, 'TestAccountCreatorIamRoleStack').create()
  // THEN
  expectCDK(stack).to(haveResource("AWS::IAM::Role"));
});

失败并出现以下错误:

 FAIL  test/account-creation-iam-role-stack.test.ts
  ✕ Test IAM Role Created (32 ms)

  ● Test IAM Role Created

    None of 0 resources matches resource 'AWS::IAM::Role' with {
      "$anything": true
    }.

      16 |   var stack = new AccountCreatorIamRoleStack(app, 'TestAccountCreatorIamRoleStack').create()
      17 |   // THEN
    > 18 |   expectCDK(stack).to(haveResource("AWS::IAM::Role"));
     |                    ^
      19 | });

我可以看到它指向那条线上的东西，但它究竟指向什么它认为是错误的？想法？

您的代码断言 AWS::IAM::Role 具有 "VisibilityTimeout": 300 但它没有这样的属性。当您的代码实际创建它时，它应该单独传递给 haveResource("AWS::IAM::Role")(没有其他属性)。

以下是 IAM 角色的当前属性:https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-iam-role.html

{
  "Type" : "AWS::IAM::Role",
  "Properties" : {
      "AssumeRolePolicyDocument" : Json,
      "Description" : String,
      "ManagedPolicyArns" : [ String, ... ],
      "MaxSessionDuration" : Integer,
      "Path" : String,
      "PermissionsBoundary" : String,
      "Policies" : [ Policy, ... ],
      "RoleName" : String,
      "Tags" : [ Tag, ... ]
    }
}```
