How to reproduce
Clone project
Add alice by running composer require alice as described in the docs
Run tests

Possible Solution
Change the versions of PHPUnit that are used?

[Romaixn]

It seems that it is due to hautelook/alice-bundle which uses an older version of sebastian/comparator : sebastianbergmann/comparator#51 (comment). It is possible to work around the problem using the solution proposed in the issue or by depending on the fork of @theofidry like mentionned here : nelmio/alice#1089

Hope this helps!

[RobQuistNL]

Okay, so I've added

    "repositories": [
        {
            "type": "vcs",
            "url": "git@github.com:theofidry/AliceBundle"
        },
    ],

to my composer.json

Then ran docker compose exec php composer require --dev alice

But;

Adding

    "optimize-autoloader": true,
    "prepend-autoloader": false,

in the config section of the composer.json seems to have helped.

[RobQuistNL]

Turns out only the latter was required, so adding "prepend-autoloader": false, fixes it.
