Note: replace 127.0.0.1 with localhost in DATABASE_URL as a workaround for this this issue: launchbadge/sqlx#846
otherwise, build with feature runtime-xxx-rustls would fail with errors like:

error: error occurred while attempting to establish a TLS connection: InvalidDNSNameError
Error:   --> src/actions.rs:29:5

...  |

42 | |     )
   | |_____^
   |
   = note: this error originates in the macro `$crate::sqlx_macros::expand_query` (in Nightly builds, run with -Z macro-backtrace for more info)

@greenhandatsjtu Can we use docker to replace these platform-specific configuration. You can refer to SQLx's solution. And here is the SQLx Github Actions Conf, we don't need multiple versions of database backend but MySQL, PosgreSQL , SQLite is needed.

Can we use docker to replace these platform-specific configuration

Hi, @hackerchai , currently, docker container is only available on Linux (https://docs.github.com/en/actions/using-containerized-services/about-service-containers#about-service-containers):

If your workflows use Docker container actions, job containers, or service containers, then you must use a Linux runner:

As a result, to support tests for windows and macOS, I have to install databases instead of using containers.
SQLx only runs tests on Ubuntu, so using containers is fine. You can refer to Diesel's CI workflow conf, they run tests on multiple os, so they don't use containers too.
