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`... 2017-09-28 12:15 GMT+02:00 Vlad Veselov <notifications@github.com>:

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.

See my previous post

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
