Looks like you forgot to run composer install.

In 2.2.0 PHPUnit version was upgraded to 6.x which introduced this new class.

hmm did a composer require magento/product-community-edition --no-update
and after that a composer update...

Just check that it removed phpunit package of version 4.1 and added a new one 6.x. Probably autoload was not regenerated or something.

[roman204]

ok now it works, but i have to delete the hole vendor dir to get it installed in the correct version

[jigar48]

I got same problem. Can you please let me know what is the solution ?

when I run the compile command

php bin/magento setup:di:compile

Its output this

Compilation was started.

See my previous post

[jigar48]

I uploaded latest vendor folder but Its not helped me

[Triloworld]

This issue is bigger.
Found that installing composer in module will break setup:di:compile.
Step to reproduce:

• Working Magento 2.2
• Install module
  Eveything working except setup:di:compile
• Run in module composer install
• Remove and add once more phpunit
  Problem exist
• Remove vendor catalog from module
  Problem resolved

There is somewhere problem path or/and multi composer installation.
Be sure to remove all vendors except main one.
Re add phpunit in version ~6.2.0 for Magento 2.2
Run composer install on end to regenerate files paths

Even more: check if vendor/bin/phpunit is symlink to vendor/phpunit/phpunit/phpunit

[jigar48]

vendor catalog is magento 2 core module how can we remove that ?

Problem still exist not solved

[Triloworld]

Sorry about not precise. /vendor catalog in custom modules create problem. I think recursive vendor in the right directory isn't problem. This is propably to second installation of composer with rewrite previous settings of path.

[jigar48]

but why its displaying the problem in this path instead of the custom extension.

I already tried with composer clear cache also composer update and install but nothing work for me

I am still looking for the hope!

[Triloworld]

Do you check symlink? Reinstall by composer phpunit in right version? Are you regenerated composer files ? What version of Magento you use? Remove /generated directory after all step

[jigar48]

Magento 2.2.1
Phpunit 6.2

Yes I have regenrated composer files because Its throwing same error as I discussed. also have tried to remove generated directly.

Also upgraded magento version to 2.2.3 but when I run compilation command it throwing error
Fatal error: Class 'PHPUnit_Framework_TestCase' not found in D:\xampp\htdocs\spicevalam2\vendor\psr\log\Psr\Log\Test\LoggerInterfaceTest.php on line 14

[jissereitsma]

I was confused here as well. I'm currently running Magento 2.2.4 and it seems to ship with PHPUnit 4, not 6: Running composer depends phpunit/phpunit tells me magento/project-community-edition 2.2.4 requires (for development) phpunit/phpunit (4.1.0). However, it turns out that my composer.json originates from way back and it mentions specifically to use PHPUnit 4. Once I started updating my composer.json by referring to the updated version https://raw.githubusercontent.com/magento/magento2/2.2/composer.json as a draft version, I was able to upgrade correctly. Perhaps this leads others to the solution as well? (Please note that you should NOT copy the entire file as an example - this is the GitHub version, not the real project version. Perhaps somebody has a better link?)

[advcha]

@jigar48 If you're using PHPUnit version 6, please replace class 'PHPUnit_Framework_TestCase' in your test file to 'PHPUnit\Framework\TestCase'. So it'd look like this:

class YourTest extends \PHPUnit\Framework\TestCase {
    ...
}

Thanks, man I was having the issue with Class 'PHPUnit_Framework_TestCase' not found in **app/code/WebShopApps/MatrixRate/test/Unit/Block/Adminhtml/Form/Field/ExportTest.php on line 37 by following your suggestion it is fixed now.

Thanks
