@desertnightsky thinks for your reply. sorry i don't understand。 getMenus() return Collection （use
unique（），i try use foreach then $this->assertEquals($userMenu->name, $menu0->name) it‘s ok .But i use each then
$this->assertEquals($userMenu->name, $menu0->name) it's Exception

@driesvints can you clarify... the version of what is not supported? Upgrade what to the latest? I've also got this issue on Laravel 5.6, PHPUnit 7.2.

anthonygore on 30 Jan 2019

@anthonygore we don't support 5.6 anymore: https://laravel.com/docs/5.7/releases#support-policy

Ah okay, thanks

I can't remember, sorry! But I'm still at Laravel 5.6 so I must have found another solution

Hi, did anyone fixed this issue in Laravel 5.6 with PHP 7.2? I have an interface which is being used in a constructor and that is causing this error. I have read that adding your class in config/app.php will resolve this error but how can we add interface in config/app.php?

This is still an issue on Laravel 6.0 (PHP 7.2, PHPUnit 8.3.5)

Auch, last comment 2 hours ago.
I also experienced this issue right now. Latest Laravel, PHPUnit 8.4.1, PHP 7.3.
I tried to run:
phpunit --testdox tests/Feature/Auth (that's a dir with tests)

DWMcload on 18 Oct 2019

How come this got closed when error still occurs in 5.8? Can you reopen this issue @driesvints please?

hey, 2k20 still not fixed, any hint?

I've seen this particular error in _strange cases_ a few times. They always "went" away after some code was fixed.

So this is very unspecific but I've seen cases where code had an error, like a PHPUnit listener had a typo or something, and the actual error was _overshadowed_ by this one.

What helped me is: debugging. I can only recommend stepping through your code and trying to pinpoint when it starts to throw the exceptions, that's how I found some bugs (in my / other, not Laraval) code.

I'll try to remember when I encounter it the next time to try to figure out what is particularly overshadowing here. Maybe it's a problem with the exception handler/the debug component, a combination of thereof, etc.

I'm having this same issue but odly only when I run phpunit --testdox it works perfectly when running phpunit.

All "Report test execution progress in TestDox format" does is display the output in a different format. Which is confusing.

I'm recently moved to a new laptop using Laravel Valet after previously using Homestead (which worked perfectly) so it may be a setup issue.

I'm having this same issue but odly only when I run phpunit --testdox it works perfectly when running phpunit.

Similar here. phpunit --testdox is working but phpunit --testdox-xml is not (throwing the BindingResolutionException). L5.5 PHPUnit 6.5

When I delete setUp() function from my test, there is no problem anymore. Even with empty setUp() there is the error.

That makes complete sense. You need to be calling parent::setUp(). If you delete it the parent will be called automatically, if it's empty then the parent won't be called.

robjbrain on 30 Apr 2020

Wow, you're right. Such a stupid mistake. Thank you very much!

abronin on 30 Apr 2020

This might not help, but this "PHP Fatal error" error message (or something like it) was happening for me when I was running some Laravel project (Laravel 5.8) tests with PHPUnit (PHPUnit 7.5.20) using a service account user.

Something that resolved this issue for me involved deleting the following PHPUnit cache file and then running the phpunit tests again: rm .phpunit.result.cache. This file was found in the base directory of my Laravel project.

Hope that helps!
