Do not depend on phpspec/prophecy #5033

staabm · 2022-08-22T07:25:59Z

we are using phpunit and don't use mocks. therefore we don't need phpspec/prophecy, which is a requirement for phpunit atm.

we would like to use phpunit on php8.2 but composer let us not install it because phpspec/prophecy seems to not yet support php 8.2.

Error: Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - phpunit/phpunit[9.4.1, ..., 9.5.22] require phpspec/prophecy ^1.12.1 -> satisfiable by phpspec/prophecy[1.12.1, ..., v1.15.0].
    - phpunit/phpunit[9.3.0, ..., 9.4.0] require phpspec/prophecy ^1.11.1 -> satisfiable by phpspec/prophecy[1.11.1, ..., v1.15.0].
    - phpunit/phpunit[9.0.0, ..., 9.2.6] require php ^7.3 -> your php version (8.2.0-dev) does not satisfy that requirement.
    - phpspec/prophecy[1.11.0, ..., 1.11.1] require php ^7.2 -> your php version (8.2.0-dev) does not satisfy that requirement.
    - phpspec/prophecy[1.12.0, ..., 1.13.0] require php ^7.2 || ~8.0, <8.1 -> your php version (8.2.0-dev) does not satisfy that requirement.
    - phpspec/prophecy[1.14.0, ..., v1.15.0] require php ^7.2 || ~8.0, <8.2 -> your php version (8.2.0-dev) does not satisfy that requirement.
    - Root composer.json requires phpunit/phpunit ^9 -> satisfiable by phpunit/phpunit[9.0.0, ..., 9.5.22].

atm we can work around the problem using --ignore-platform-req=php+ composer cli switch.

I guess our situation is similar for other phpunit uses which also don't use mocks...

do you think its feasible to drop this dependency - or at least consider it optional in future phpunit versions?

thanks for the great tool.

This has been discussed in #4141 and #4142.

TL;DR: The dependency on Prophecy has been removed for PHPUnit 10. Anything related to out-of-the-box support for Prophecy is deprecated since PHPUnit 9.1.

If we remove the dependency on phpspec/prophecy in the composer.json of PHPUnit 8.5 and PHPUnit 9.5, then PHPUnit would continue to work as-is for any developer who does not use Prophecy (through TestCase::prophesize()).

For developers who use TestCase::prophesize() in their tests, PHPUnit will stop to work unexpectedly. If they add a dependency on phpspec/prophecy in the composer.json of their project then their tests should work again.

Of course, we should be able to detect in TestCase::prophesize() whether Prophecy is available and trigger an error with a descriptive message ("Please add a dependency on phpspec/prophecy to your composer.json").

However, I do not know what to do here. If we do not do anything, PHPUnit 8.5 and PHPUnit 9.5 cannot be installed without hassle until Prophecy allows PHP 8.2 in their composer.json. And PHP 8.3 next year, and so on. If we drop the dependency on Prophecy for PHPUnit 8.5 and PHPUnit 9.5, even with a nice error message, then we break the tests for everyone who uses TestCase::prophesize(), and in a bugfix release, no less.

staabm · 2022-08-22T08:05:57Z

thanks for the in-detail anwser. great to see this is a solved problem for phpunit 10+.

after reading your reply I get the feeling the easierst way forward, without BC breaks etc, would be to make people aware of the workaround, namely using the --ignore-platform-req=php+ composer cli switch on php 8.2.

sebastianbergmann · 2022-08-22T08:07:41Z

According to phpspec/prophecy#556 (comment), the following also works:

"replace": { "phpspec/prophecy": "*" }

sebastianbergmann · 2022-08-22T08:11:19Z

Also note that you do not suffer from this problem if you use PHPUnit from a PHP Archive (PHAR) instead of installing it using Composer.

sebastianbergmann · 2022-08-22T08:26:17Z

"replace": { "phpspec/prophecy": "*" }

Never used "replace" before today, but I can confirm that the above works (as in: it installs PHPUnit without Prophecy and Prophecy's dependencies):

…ment) as well as possible workarounds

sebastianbergmann · 2022-08-22T09:31:24Z

make people aware of the workaround, namely using the --ignore-platform-req=php+ composer cli switch on php 8.2.

I have added a section on this to the documentation for PHPUnit 8.5 and PHPUnit 9.5.

sebastianbergmann · 2022-08-22T10:26:49Z

This would be the patch for the 9.5 branch to remove the dependency on Prophecy:

If we released a PHPUnit 9.5.23, for instance, with these changes then

PHPUnit would not pull in Prophecy and can therefore be installed without workaround on PHP 8.2
nothing would change for developers who do not use TestCase::prophesize()
errors would be triggered for tests that use TestCase::prophesize()

Developers that use TestCase::prophesize() can restore the current behaviour by adding "phpspec/prophecy": "^1.12.1" to their project's composer.json file.

This would not result in an API BC break, but it would make a composer.json change necessary for developers that use Prophecy. I have no idea how many developers would be affected by this change.

Thoughts?

PS: If we do this, then these documentation changes need to be reverted:

oliverklee · 2022-08-22T10:37:17Z

I would be fine with this approach (dropping the dependency).

localheinz · 2022-08-22T10:40:37Z

@sebastianbergmann

To clarify, I would not recommend to replace dependencies in packages: when a package A requires a package B, and package B replaces package C, then package C will not be available for package A, and of course, neither for dependents of package A.

It's totally fine to replace packages in applications, though!

RageZBla · 2022-08-22T10:43:40Z

Same dropping the dependencies is fine by me even if means I need to declare it explicitly (in my composer.json) to use Prophecy.

@sebastianbergmann as always thanks for for your work.

Pierstoval · 2022-08-22T10:44:59Z

Throwing an error saying something like You are using Prophecy in the "%s" test class. Out-of-the-box support for Prophecy stopped at phpunit X.Y, please run "composer install ..." To fix this issue seems like the best solution to me.

As said above by other peers, it would have zero impact on devs that don't use prophecy (like me), and will be part of the natural upgrade process for devs using it and migrating to newer versions of phpunit

sebastianbergmann · 2022-08-22T10:48:27Z

Do you think that

This test uses TestCase::prophesize(), but phpspec/prophecy is not installed. Please run "composer require --dev phpspec/prophecy ^1.12.1".

good enough as an error message?

acelaya · 2022-08-22T10:51:19Z

As a user that's still using prophecy for mocks, I would say it's fine to remove the dependency from PHPUnit.

It's a dev dependency, which means the error will show up for everyone early enough in the development process.
Solving it is super straightforward (as long as the error message is clear), so even if caught during CI just before a deployment or similar, the change to fix it is quick to do and push.
The usage of TestCase::prophesize, was already throwing a warning since a couple of versions ago, which means most people using it probably migrated to something like phpspec/prophecy-phpunit, which already depends on phpspec/prophecy itself.

sebastianbergmann · 2022-08-22T11:22:02Z

Thank you all for your valuable input. These changes will be implemented for PHPUnit 8.5.29 and PHPUnit 9.5.23.

These changes will be implemented for PHPUnit 8.5.29 and PHPUnit 9.5.23.

You do not have to wait for these new releases to add phpspec/prophecy to your project's dependencies (in case you actually use TestCase::prophesize()).

If we released a PHPUnit 9.5.23, for instance, with these changes then
* PHPUnit would not pull in Prophecy and can therefore be installed without workaround on PHP 8.2

According to phpspec/prophecy#556 (comment), the following also works:

This works for me only if I have only one composer dependency with this “hack” installed.

Levivb · 2022-08-22T22:56:54Z

Do you think that

This test uses TestCase::prophesize(), but phpspec/prophecy is not installed. Please run "composer require --dev phpspec/prophecy ^1.12.1".

good enough as an error message?

Perhaps add a link to this very issue in the error message for developers wanting more (background) information?

Something like:
This test uses TestCase::prophesize(), but phpspec/prophecy is not installed. Please run "composer require --dev phpspec/prophecy ^1.12.1". See https://github.com/sebastianbergmann/phpunit/issues/5033 for more information

Not impacted by this change myself, but it could give those impacted a bit more to go on :)
