I hit this error on one project but not another. Both have 8.9.14.. I wonder if there's a dependency conflicting somewhere?

[damienmckenna]

I worked out the problem: there were some dependencies in the "require-dev" portion of the project's composer.json file which were conflicting, I removed a bunch of them and added "drupal/core-dev" to the project and it worked for me.

Thanks a lot @damienmckenna! your suggestion worked great for me.

The root composer.json had this require-dev section:

    "require-dev": {
        "behat/mink": "~1.7",
        "behat/mink-goutte-driver": "~1.2",
        "jcalderonzumba/gastonjs": "~1.0.2",
        "jcalderonzumba/mink-phantomjs-driver": "~0.3.1",
        "mikey179/vfsstream": "~1.2",
        "phpunit/phpunit": ">=4.8.28 <5",
        "symfony/css-selector": "~2.8"
    }

Which I manually updated to replace all those constraints with just "drupal/core-dev": "^8 || ^9"; then I used composer to properly resolve the new set of constraints by running:

composer require drupal/core-dev:"^8.9.14 || ^9" --dev --update-with-dependencies

Which resulted in a require-dev section that looks like this:

    "require-dev": {
        "drupal/core-dev": "^8.9.14 || ^9"
    }

After that, I was able to run drupal-check (via drush upgrade_status:analyze my_module) without the error about PHPUnit_Framework_AssertionFailedError.

phpstan-drupal also had fixes around this. Closing out
