Trying to test method with output stream in separate process, also as recommended here - https://phpunit.de/manual/current/en/appendixes.annotations.html#appendixes.annotations.preserveGlobalState
set the @preserveGlobalState disabled annotation, but the test fails with error:

There was 1 error:

1) rjapitest\unit\BaseControllerTest::testJsonApiIndex
PHPUnit\Framework\Exception: {"data":[{"type":"article","id":"36","attributes":{"title":"Foo bar Foo bar Foo bar Foo bar 123456789"},"links":{"self":"localhost\/article\/36"}},{"type":"article","id":"37","attributes":{"title":"Foo bar Foo bar Foo bar Foo bar 123456789"},"links":{"self":"localhost\/article\/37"}},{"type":"article","id":"38","attributes":{"title":"Foo bar Foo bar Foo bar Foo bar 123456789"},"links":{"self":"localhost\/article\/38"}}]}

ERRORS!

The executed code snippet:

    /**
     * @runInSeparateProcess
     * @preserveGlobalState disabled
     */
    public function testJsonApiIndex()
    {
        $_SERVER['HTTP_HOST'] = 'localhost';
        $request = new \Illuminate\Http\Request();
        $request->merge([
            'limit' => 10,
            'page' => 1,
            'data' => '["title", "description"]',
            'order_by' => '{"title":"asc", "created_at":"desc"}',
            'filter' => '[["updated_at", ">", "2017-01-03 12:13:13"], ["updated_at", "<", "2017-01-03 12:13:15"]]',
        ]);
        $this->articleController->index($request);
    }

There are no assertion methods there, but it doesn't matter in this particular case.
Glad to any help.

Any thoughts?

[jaymecd]

faced same issue yesterday. phpunit 6.1.2

[geoandri]

I am having the same issue. Did you manage to find any solution?

[sebastianbergmann]

Thank you for your report.

Please provide a minimal, self-contained, reproducing test case that shows the problem you are reporting.

Without such a minimal, self-contained, reproducing test case I will not be able to investigate this issue.

[sebastianbergmann]

No feedback, closing.

This is still broken in 6.5.5, to reproduce uncomment the test at https://github.com/omines/datatables-bundle/blob/1d59c28d43070233c142f479c3894a5dde3da3c3/tests/Unit/Adapter/ElasticaTest.php#L102-L114

I had the same problem. I fixed it by adding a require_once('vendor/autoload.php'); at the top of the test class

PhPUnit 7.1.0

from vendor packages installed with composer.

PHPUnit\Framework\Exception: Doctrine\Common\Collections\ArrayCollection {#480

for

        $client = static::createClient([], ['HTTPS' => true]);
        $crawler = $client->request('GET', $url);

It was working on PhPUnit 6 i think, so before upgrade

         stopOnFailure="false">

Without processIsolation we got

Doctrine\Common\Collections\ArrayCollection {#5735
  -elements: []
}

And that is it, result of test
