unable to run phpunit in tests directory

[sneakyimp]

I have encountered what appears to be a problem in the phpunit.xml file in the latest develop branch of CI3.

I posted another issue that the README file in the tests directory no longer works. I spent some time installing phpunit according to the latest instructions and I installed vfsStream using composer and tried to get around the error reported by composer on my MacOs laptop:

sed: 1: "vendor/mikey179/vfsstre ...": invalid command code v
Script sed -i s/name{0}/name[0]/ vendor/mikey179/vfsstream/src/main/php/org/bovigo/vfs/vfsstream.php handling the post-install-cmd event returned with error code 1

As suggested here I modified that sed statement as follows:

sed -i .bak s/name{0}/name[0]/ vendor/mikey179/vfsstream/src/main/php/org/bovigo/vfs/vfsstream.php

This seems to run. I do not know if this performs the necessary step, but phpunit appears to run now without vfstream complaints.

HOWEVER, phpunit fails:

$ phpunit
PHPUnit 10.0.19 by Sebastian Bergmann and contributors.

Test directory "/home/sneakyimp/ci3/tests/./codeigniter/core" not found

It would seem that there is a problem with the file tests/phpunit.xml, which specifies this path and a couple of others:

<?xml version="1.0" encoding="UTF-8"?>

<phpunit
	bootstrap="./Bootstrap.php"
	colors="true"
	convertNoticesToExceptions="true"
	convertWarningsToExceptions="true"
	stopOnError="false"
	stopOnFailure="false"
	stopOnIncomplete="false"
	stopOnSkipped="false"
	beStrictAboutTestsThatDoNotTestAnything="false">
	<testsuites>
		<testsuite name="CodeIgniter Core Test Suite">
			<directory suffix="test.php">./codeigniter/core</directory>
			<directory suffix="test.php">./codeigniter/helpers</directory>
			<directory suffix="test.php">./codeigniter/libraries</directory>
		</testsuite>
	</testsuites>
	<filter>
		<whitelist>
			<directory suffix=".php">../system/</directory>
		</whitelist>
	</filter>
</phpunit>

These paths appear wrong? There is no folder/directory in the CI3 codebase named codeigniter. If you replace /codeigniter/ with /mocks/ then phpunit will run, but complains there is no helpers subdir. removing that, phpunit will finally run, but complains about a deprecated schema, and runs no tests:

$ phpunit
PHPUnit 10.0.19 by Sebastian Bergmann and contributors.

Runtime:       PHP 8.2.3
Configuration: /home/sneakyimp/ci3/tests/phpunit.xml

There was 1 PHPUnit warning:

1) Your XML configuration validates against a deprecated schema. Migrate your XML configuration using "--migrate-configuration"!

No tests executed!

AFAIK, phpunit 10 is not supported as of today.
You would have to migrate the configuration, but after this you will encounter other issues: See also #6219

Try with a previous version.
