Current behavior

Getting below error

● SecretsManagerServiceModule › #forFeature() › Shold have plain string secret (without id)

    Nest can't resolve dependencies of the testString (?). Please make sure that the argument SECRET_MANAGER_SERVICE at index [0] is available in the SecretManagerServiceModule context.

    Potential solutions:
    - If SECRET_MANAGER_SERVICE is a provider, is it part of the current SecretManagerServiceModule?
    - If SECRET_MANAGER_SERVICE is exported from a separate @Module, is that module imported within SecretManagerServiceModule?
      @Module({
        imports: [ /* the Module containing SECRET_MANAGER_SERVICE */ ]
      })

tests/unit/services/secrets-manager/secrets-manager.module.spec.ts Below Test case not able to resolve dependency

test('Shold have plain string secret (without id)', async () => {
      const response: AWS.SecretsManager.GetSecretValueResponse = {
        SecretString: 'hello',
      };

      AWSMock.mock('SecretsManager', 'getSecretValue', Promise.resolve(response));
      const module: TestingModule = await Test.createTestingModule({
        imports: [
          SecretManagerServiceModule.forRoot({}),
          SecretManagerServiceModule.forFeature({
            confiiguration: [{ secretName: 'testString', secretType: 'plain' }],
          }),
        ],
      }).compile();
      const plainString = module.get('testString');
      expect(plainString).toEqual('hello');
    });

Expected behavior

this test case should be passed

Your're trying to inject SECRET_MANAGER_SERVICE in src/services/secrets-manager/secrets.provider.ts: inject: [getSecretsManagerToken(secretsManagerServiceFeatureOptions.id)], But it's not injected any where.

SecretManagerServiceModule.forRoot function exports SECRET_MANAGER_SERVICE provider. i have follewed the same structure as nestjs/mongoose library

[Boshen]

What are you trying to achieve with your test? forRoot or forFeature should be used independently, not together - SECRET_MANAGER_SERVICE should be provided at the module level, they are not shared cross modules, you have to either import its containing module or inject it somehow.

Since its a test case, you should provide it manually in your test with .overrideProvider and .useValue.

Either case this is not a bug with nestjs.
