You can configure different environment connection strings in different appsettings files like this-

For test environment, use appsettings.test.json

 "Data": {
    "MyDbContext": {
      "ConnectionString": "" /*<<== TestDatabase connection string */
    },

For prod environment, use appsettings.prod.json

 "Data": {
    "MyContext": {
      "ConnectionString": "" /*<<== ProdDatabase connection string */
    },

Use ASPNETCORE_ENVIRONMENT environment variable to set current environment as Test or Prod values.

In Startup, you can use like this-

     services.AddDbContext<MyContext>(options =>
options.UseSqlServer(Configuration["Data:MyContext:ConnectionString"]));
