Question

问题：

执行测试用例时出现问题

Nest无法解析AWSSecretManagerStringConfigTest（？）的依赖项。请确保_RootTestModule上下文中的索引[0]处的参数testString可用。

我正在使用所有最新版本的nestjs软件包

错误日志：

AWSModule（SecretsManager服务）›应该具有纯字符串秘密

all-test         | 
all-test         |     Nest can't resolve dependencies of the AWSSecretManagerStringConfigTest (?). Please make sure that the argument testString at index [0] is available in the _RootTestModule context.
all-test         | 
all-test         |     Potential solutions:
all-test         |     - If testString is a provider, is it part of the current _RootTestModule?
all-test         |     - If testString is exported from a separate @Module, is that module imported within _RootTestModule?
all-test         |       @Module({
all-test         |         imports: [ /* the Module containing testString */ ]
all-test         |       })

测试案例：

此测试案例对我来说是正确的

test('Shold have plain string secret', async () => {
    const response: AWS.SecretsManager.GetSecretValueResponse = {
      SecretString: 'hello',
    };

    AWSMock.setSDKInstance(AWS);
    AWSMock.mock('SecretsManager', 'getSecretValue', Promise.resolve(response));
    const module: TestingModule = await Test.createTestingModule({
      imports: [
        AWSModule.forServices([{ serviceName: 'secrets-manager' }]),
        AWSModule.forServicesFeature([
          { serviceName: 'secrets-manager', confiiguration: [{ secretName: 'testString', secretType: 'plain' }] },
        ]),
      ],
    }).compile();
    const plainString = module.get('testString');
    expect(plainString).toEqual('hello');
    AWSMock.restore();
  });

但是当我尝试在测试用例下执行时，它给了我错误

test('Should have plain string secret', async () => {
    const response: AWS.SecretsManager.GetSecretValueResponse = {
      SecretString: 'hello',
    };

    AWSMock.setSDKInstance(AWS);
    AWSMock.mock('SecretsManager', 'getSecretValue', Promise.resolve(response));
    const module: TestingModule = await Test.createTestingModule({
      imports: [
        AWSModule.forServices([{ serviceName: 'secrets-manager' }]),
        AWSModule.forServicesFeature([
          { serviceName: 'secrets-manager', confiiguration: [{ secretName: 'testString', secretType: 'plain' }] },
        ]),
      ],
      providers: [AWSSecretManagerStringConfigTest],
    }).compile();
    const awsSecretManagerStringConfigTest = module.get(AWSSecretManagerStringConfigTest);
    expect(awsSecretManagerStringConfigTest).toBeInstanceOf(AWSSecretManagerStringConfigTest);
    expect(awsSecretManagerStringConfigTest.getSecret()).toEqual('hello');
    AWSMock.restore();
  });

AWSSecretManagerStringConfigTest.ts

import { Injectable, Inject } from '@nestjs/common';

@Injectable()
export class AWSSecretManagerStringConfigTest {
  constructor(@Inject('testString') private readonly secret: string) {}

  getSecret(): string {
    return this.secret;
  }
}

Nest.js无法解决依赖关系
