[Bug]: The documented approach to testing doesn't work for a scaffolded typescript project

Describe the bug

If you generate a new Typescript-based Strapi project and then follow the instructions in the testing documentation, Strapi fails to start properly. This appears to be because all the config files are .ts files, whereas the code to load the configuration files requires them to have .js or .json extensions.

Additional context

No response

Suggested improvements or fixes

Add a section to the testing page mentioning what extra steps are required for typescript projects, which from what I've been able to work out is something like

const appContext = await Strapi.compile();
const instance = Strapi(appContext);
await instance.load();

Because of the documentation I am seeing errors like: "Unknown dialect undefined"

The example should be something like this or as suggested by @timbarclay

await Strapi({
  appDir: process.cwd(),
  distDir: process.cwd() + "/dist",
  autoReload: false,
  serveAdminPanel: false
}).load();

This documentation also says:

^okay... so then what do we do when the example only shows us how to use sqlite? Can we get examples on postgres?

that means that in your env no database is set.

Hi,
Thanks for reporting. I'm closing this issue, but it's included in the meta issue about reworking the Testing page (#1940).
In the meantime I'll check with Strapi engineers to see if they can come up with a solution.
