phpunit: Exception: "Cannot find TestCase object on call stack" (with example)

Q A
PHPUnit version 10.2.0
PHP version 8.2.6
Installation Method Composer

Summary

Note: I apologise, I originally wrote this issue when using orchestra/testbench (Laravel). However I dug further into Laravel to find out the relevant factor (it sets an error handler), and have updated this issue to use only PHPUnit. The original post is included at the end.

Hi there. I found a situation which causes PHPUnit to throw an exception.

NoTestCaseObjectOnCallStackException with message “Cannot find TestCase object on call stack”.

Current behavior

I’ve been able to reproduce this in a particular circumstance:

  • There are at least two test classes
  • The first one (aphabetically) registers an error handler
  • PHPUnit is run with the --filter=xxx option that includes the first test

A NoTestCaseObjectOnCallStackException is thrown, with the output:

An error occurred inside PHPUnit.

How to reproduce

I created a repo to demonstrate this issue, please refer to that for a working example.

  1. Create two test classes. The first one (alphabetically) will register an error handler.
<?php
// ATest.php

use PHPUnit\Framework\TestCase;

class ATest extends TestCase
{
    public static function test_something_a(): void
    {
        set_error_handler([self::class, 'handleError']);

        print "\n\"Running ATest::test_something_a()\"\n";

        self::assertTrue(true);
    }

    public static function handleError(
        int $errno,
        string $errstr,
        string $errfile = '',
        int $errline = 0,
        array $errcontext = [],
    ): void {
        print "This won't be called";
    }
}

<?php
// BTest.php

use PHPUnit\Framework\TestCase;

class BTest extends TestCase
{
    public static function test_something_b(): void
    {
        print "\n\"Running BTest::test_something_b()\"\n";

        self::assertTrue(true);
    }
}
  1. Run the tests with the --filter=xxx option, so that it includes ATest:
./vendor/bin/phpunit --filter=test_something

Expected behavior

The tests should run without the exception being thrown.

Observations

These are the steps leading up to the exception being thrown:

  1. PHPUnit\Runner\Filter\NameFilterIterator:75 generates (a suppressed) PHP warning “preg_match(): Delimiter must not be alphanumeric, backslash, or NUL”
  2. PHPUnit\Runner\ErrorHandler:71 handles this warning, and calls PHPUnit\Event\Code\TestMethodBuilder::fromCallStack()
  3. The exception is triggered by PHPUnit\Event\Code\TestMethodBuilder:62 when it isn’t able to find a TestCase class in the PHP stack trace.

Changes that cause the exception to not occur:

  • Changing the order of ATest and BTest (by renaming them), or
  • Removing BTest, or
  • Running phpunit with --filter=xxx that doesn’t include ATest, or
  • Running phpunit without the --filter=xxx option

This doesn’t seem to occur with phpunit ^9.0.

How to reproduce

I created a repo to demonstrate this issue, please refer to that for a working example.

  1. Install Orchestra\Testbench:
composer require orchestra/testbench:^8.0
  1. Create two test classes. The first one (alphabetically) will extend from Orchestra\Testbench\TestCase. The second can extend from either that, or PHPUnit\Framework\TestCase.
<?php
// ATest.php

use Orchestra\Testbench\TestCase as TestCase;
//use PHPUnit\Framework\TestCase;

class ATest extends TestCase
{
    public static function test_something_a(): void
    {
        dump('running ATest::test_something_a');
        self::assertTrue(true);
    }
}

<?php
// BTest.php

//use Orchestra\Testbench\TestCase as TestCase;
use PHPUnit\Framework\TestCase;

class BTest extends TestCase
{
    public static function test_something_b(): void
    {
        dump('running BTest::test_something_b');
        self::assertTrue(true);
    }
}
  1. Run the tests with the --filter=xxx option, so that it includes the first test:
./vendor/bin/phpunit --filter=test_something

Expected behavior

The tests should run without the exception being thrown.

Observations

Although orchestra/testbench is used to trigger the error, it seems to be related to the way PHPUnit handles a PHP warning that Testbench generates.

These are the steps leading up to the exception being thrown:

  1. Testbench generates PHP warning: “file_get_contents(/var/www/html/code-distortion/phpunit-bug/vendor/orchestra/testbench-core/laravel/.env): Failed to open stream: No such file or directory”
  2. PHPUnit\Runner\ErrorHandler:71 handles this warning, and calls PHPUnit\Event\Code\TestMethodBuilder::fromCallStack()
  3. The exception is triggered by PHPUnit\Event\Code\TestMethodBuilder:62 when it isn’t able to find a TestCase class in the PHP stack trace.

Changes that cause the exception to not occur:

  • Changing the order of ATest and BTest (by renaming them), or
  • Updating ATest to extend from PHPUnit\Framework\TestCase, or
  • Removing BTest, or
  • Running phpunit with --filter=xxx that doesn’t include the first test, or
  • Running phpunit without the --filter=xxx option

This doesn’t seem to occur with earlier versions, when either orchestra/testbench ^7.0, or phpunit ^9.0 is used.

I’ve been stuck on this issue for over a week and now I’ve discovered a solution.

In my tested classes, set_error_handler is set and in PHP 8.3 the following exception appeared:

Cannot find TestCase object on call stack

This happens because phpunit conflicts with your custom error handler.

The solution is to call the restore_error_handler() function before performing the tests.

This issue happened in PHPUnit ^10.2 and only with PHP 8.3. With PHP 8.1 and 8.2 this issue does not appear.

I’m still having this problem right now with laravel 10.37.1 and phpunit 10.5.2

Please understand that I cannot investigate problems that involve third-party extensions for / wrappers around PHPUnit such as Pest.

Definitely, that’s not your job! I was just not aware that this is PEST specific and should be handled there, as downgrading to PHPUnit v10.1.3 fixed it. Thanks for your hard work on the gold standard testing framework in PHP!

Hi @sebastianbergmann. Thanks for fixing this in v10.2.1. But I am still experiencing this bug in a Laravel 10 project with latest PEST v2.6.3 / PHPUnit v10.2.1, e.g.:

$ php artisan test --filter HasActiveFlagTest

   ERROR  Cannot find TestCase object on call stack

as a workaround, I had to downgrade to PHPUnit v10.1.3, and that ERROR no longer pops up.

Also, others report the same, https://stackoverflow.com/a/76404292/5982842

I still get this error after upgrading to 10.2.1 😦 – St. Jan Jun 7 at 15:41

Thank you for bringing this up.

This happens because PHPUnit’s error handler tries to emit an event for the suppressed E_WARNING error triggered by preg_match() in NameFilterIterator. Somehow we missed that going from 758cdcce2682bda2b5b7958dd470537f8622f094 over 12340577a2719266b7072f3036db7488a00ff05c to #5326, #5293, and #5328.

As of 16166431bce84bb100d8e7fe867d612bdfe61776, PHPUnit’s error handler no longer emits events for suppressed errors in PHPUnit’s own code (or code of its dependencies).

It’s “interesting”, though, that the error you reported is only triggered when a test and/or the code under test registers its own error handler. But supporting custom error handlers (in addition to PHPUnit’s own error handler) is not a priority for me so I won’t investigate that further.

Your example work as expected as of 16166431bce84bb100d8e7fe867d612bdfe61776.
