我正在尝试对使用TypeORM连接更新sqlite数据库的服务进行单元测试。
看起来没有固定的方法来单元测试TypeORM，所以我试图找到任何可行的方法。根据以下内容，我决定尝试使用内存中的数据库进行测试***：
https://github.com/typeorm/typeorm/issues/1267#issuecomment-483775861
这里的代码使用了Jest，所以我尝试转换到Jasmine，这是我的测试环境。
作为原理证明，如果我在 database-test.spec.ts 中执行以下操作

import { createConnection, Entity, getRepository } from "typeorm";
import { PrimaryGeneratedColumn, Column } from "typeorm";
import { fakeAsync, async } from "@angular/core/testing";

@Entity()
export class MyEntity {
  @PrimaryGeneratedColumn()
  id?: number;

  @Column()
  name?: string;
}

describe("Database test", () => {
  it("store Joe and fetch it", fakeAsync(() => {
    createConnection({
      name: "testing",
      type: "sqlite",
      database: ":memory:",
      dropSchema: true,
      entities: [MyEntity],
      synchronize: true,
      logging: false,
    }).then(conn => {
      conn.getRepository(MyEntity).insert({
        name: "Joe",
      });
      const joe = getRepository(MyEntity).find({
        where: {
          id: 1,
        },
      });

      expect(joe[0].name).toBe("Joe");
      conn.close();
    });
  }));
});

无论我做什么我得到错误

SQLite已安装并在测试之外运行。为什么在测试过程中会出现此错误？

安装sqlite3。
如果typeorm选项被指定为database:':memory'，则会创建sqlite，并使用sqlite3库在运行示例中使用。
如果您想使用外部sqlite3，请检查此页面。

我在Postgres上遇到了同样的问题。我们正在使用git workspaces，看起来typeorm在寻找驱动程序，但是在错误的位置（pg安装在根node_modules git文件夹中，而不是workspaceA/node_modules中）。
解决方法是在连接期间提供驱动程序：

import { DataSource } from "typeorm";
import { models } from "../models";
import { TextEncoder } from "util";
global.TextEncoder = TextEncoder;

export default class AppDataSource {
  static build(): DataSource {
    return new DataSource({
      type: "postgres",
      url:
        process.env.POSTGRES_URL ||
        `postgres://${process.env.POSTGRES_USER || "user"}:${
          process.env.POSTGRES_PASSWORD || "password"
        }@${process.env.PG_HOST || "localhost"}:${
          process.env.POSTGRES_PORT || 5254
        }/${process.env.POSTGRES_DB || "db"}`,
      schema: process.env.PG_SCHEMA,
      entities: models,
      installExtensions: false,
      migrationsTableName: "migrations",
      synchronize: process.env.NODE_ENV === "development",
      // ADD THIS LINE
      driver: require("pg")
    });
  }
}
