未获取环回4测试配置 [英] Loopback 4 test configurations are not picked up

问题描述

我遵循了 Loopback4数据源文档，并放置了 sample.datasource src/datasources 下的.json 和 sample.test.datasource.json 文件.每当我运行npm run test时，我的存储库就会注入原始数据源，而不注入测试数据源.

我的数据源配置文件sample.datasource.json是

{
  "name": "sample",
  "connector": "postgresql",
  "url": "postgres://postgres:user@localhost:5432/somedb",
  "host": "localhost",
  "port": 5432,
  "user": "postgres",
  "password": "****",
  "database": "somedb"
}

和我的测试配置文件sample.test.datasource.json是

{
  "name": "sample",
  "connector": "memory",
  "localStorage": "sample-test",
  "debug": true
}

这是我的存储库文件 sample.repository.ts ，位于src/repositories下.

export class SampleRepository extends DefaultCrudRepository<SomeModel,string> {
  constructor(
    @inject('datasources.sample') dataSource: SomeDataSource,
  ) {
    super(SomeModel, dataSource);
  }
}

我将NODE_ENV导出到测试"并尝试运行npm run test.

解决方案

来自LoopBack团队的你好:)

LoopBack 4目前还不支持特定于环境的配置.我们正在GitHub issue#1464 中讨论此功能，还有一个有关专门针对测试修改数据源配置的讨论-请参见 issue#1396 .

有可能的解决方法，请参见以下资源以获取灵感:

• https://loopback.io /doc/en/lb4/Deploying-to-IBM-Cloud.html#updating-application
• https://itnext.io/loopback-4-database-configuration-8f085399268

I followed Loopback4 datasources documentation and placed sample.datasource.json and sample.test.datasource.json files under src/datasources. Whenever I run npm run test my repository is injected with original datasource but not the test datasource.

My datasource configuration file sample.datasource.json is

{
  "name": "sample",
  "connector": "postgresql",
  "url": "postgres://postgres:user@localhost:5432/somedb",
  "host": "localhost",
  "port": 5432,
  "user": "postgres",
  "password": "****",
  "database": "somedb"
}

and my test configuration file sample.test.datasource.json is

{
  "name": "sample",
  "connector": "memory",
  "localStorage": "sample-test",
  "debug": true
}

Here is my repository file sample.repository.ts placed under src/repositories.

export class SampleRepository extends DefaultCrudRepository<SomeModel,string> {
  constructor(
    @inject('datasources.sample') dataSource: SomeDataSource,
  ) {
    super(SomeModel, dataSource);
  }
}

I exported NODE_ENV to "test" and tried to run npm run test.

解决方案

Hello from the LoopBack team :)

LoopBack 4 does not support environment specific configuration yet. We are discussing this feature in the GitHub issue #1464, there is also a discussion about modifying datasource configuration specifically for tests - see issue #1396.

There are workaround possible, see the following resources for inspiration:

• https://loopback.io/doc/en/lb4/Deploying-to-IBM-Cloud.html#updating-application
• https://itnext.io/loopback-4-database-configuration-8f085399268
