TYPO3 Core

Unfortunately it is not possible to --prefer-source for one package only in Composer, so this is not an option, because I don't want all of my other dependencies be downloaded via sources as well.

For me it still seems like a bug, because the class, which exists in package FunctionalTestCase depends on class, which doesn't exist in package FunctionalTestCaseBootstrapUtility, which makes it useless at all.

Also in provided issue #77205 a solution is also not in using --prefer-source, but in restoring missing file in package.

The correct solution, as I can imagine would be either:
1. Make dependencies of base test classes be also available in package
or
2. Provide a separate dev-package, which can be included as dependency in "require-dev" and which provides all the Unit-Functional-testing data (including fixtures, base tests and so on).

You can just switch one package as well

"config": {
    "preferred-install": {
      "typo3/cms": "source",
      "*": "dist" 
    },
  }

At the moment we automatically deploy (exactly) the tested TYPO3 instance – I guess using `preferred-install` and `source` for `typo3/cms` will work for us – as long as we exclude the `.git` directory from deployment. Unfortunately using `source` will slow down our builds because composer will (a) not be able to load `typo3/cms` from composer's cache and (b) will (by definition) not use a distribution (which "can speed up installs substantially"), right?

Georg, thank you for the tip! I was looking in wrong direction at Composer's docs.

Nevertheless, I still find this a bit confusing (class from package relies on class, which doesn't exist in package). But as I understand, form a SO issue there are plans to change this in next minor versions, right?

With TYPO3 7.6.14 I get the following error when executing functional tests:

PHPUnit_Framework_Exception: PHP Fatal error: Class 'TYPO3\CMS\Core\Tests\FunctionalTestCaseBootstrapUtility' not found

I've added

"config": {
    "preferred-install": {
      "typo3/cms": "source",
      "*": "dist" 
    }
  }

to my root composer.json of the project. The class file itself exists in the TYPO3 core but can obviously not be loaded.

I've created a simple package to reproduce the issue. You can find it here: https://github.com/utrotzek/functionaltest_test/

When you follow the instructions described in the repo, you will have a fresh TYPO3 with the example package containing one simple functional test.
After you execute the functional tests you will get the following error:

PHPUnit_Framework_Exception: PHP Fatal error: Class 'TYPO3\CMS\Core\Tests\FunctionalTestCaseBootstrapUtility' not found.

The Class FunctionalTestCaseBootstrapUtility is present in the following path 'WWW/typo3/sysext/core/Tests/FunctionalTestCaseBootstrapUtility.php' so it seems that it is because of an autoloading issue. I'm no autoloading expert, but as far as I know the autoloading definition in the core package

"autoload-dev": {
"psr-4": {
"TYPO3\\CMS\\Core\\Tests\\": "Tests/"
}
}

does not work since autoload-dev will only work in root composer json.

So in my opinion the FunctionalTestCaseBootstrapUtility should be moved to Classes directory or the "autoloading" definition from "autoload-dev" should be moved to "autoload"

You need to add the "autoload-dev" from core package to your own composer.json, there is no other way to solve this. (Beside creating a package witch include the Test API parts).

So I'd like to close this issue, is it ok for you?

Hi, Alexander.

Yes, If copy-paste of autoload-dev solves an issue, then this ticket can be closed.
