How to automate local tests against multiple dependency versions?

[lezhnev74]

I have an app which must work with a specific package in various versions. I'd like to automatically run local tests against different versions of the package.

How is it done?

I can only think of a manual way:

• change composer.json
• run composer update
• run tests
• repeat with another version

Well, I suggest you to write a script automating the different steps you gave here. There is nothing forcing to do such steps manually.

So you have this app code pushed to different branches? Then in each branch have the right dependency for the package and automated the tests.

About automation as suggested just instead of

change composer.json
run composer update

simply
composer require vendor/package:$(MY_PACKAGE_VERSION)

Yes, looks like this is a way to do it.
Since dependencies are cached that should not take too much time to pull another version.
