FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Jasny PHPUnit extension
Additional functionality for PHPUnit.
- Callback mock - assert that callback is called with correct arguments.
- Expected warning - assert notice/warning is triggered and continue running.
- In context of - Access private/protected methods and properties.
- Consecutive calls - Replacement for removed
withConsecutive()method.
Installation
composer require jasny/phpunit-extensionUsage
Callback mock
MockObject createCallbackMock(InvocationOrder $matcher, array|Closure $assert = null, $return = null)The method takes either the expected arguments as array and the return value or a Closure. If a Closure is given,
it will be called with an InvocationMocker, which can be used for more advanced matching.
Safe Mocks
The SafeMocksTrait overwrites the createMock method to disable auto-return value generation. This means that the
test will fail if any method is called that isn't configured.
In the example above, the method bye() isn't configured for $foo. Normally the test would succeed, but with
SafeMocksTrait this test will result in the failure
Return value inference disabled and no expectation set up for Foo::bye()Expected warning
ExpectedWarningTrait overwrites the following methods;
expectNotice()expectNoticeMessage(string $message)expectNoticeMessageMatches(string $regexp)expectWarning()expectWarningMessage(string $message)expectWarningMessageMatches(string $regexp)expectDeprecation()expectDeprecationMessage(string $message)expectDeprecationMessageMatches(string $regexp)
Take the following example function;
PHPUnit converts notices and warning to exceptions. While you can catch these exceptions through methods like
expectDeprecation, any code after the the notice/warning isn't run and therefor untestable.
The following test succeeds, while it should fail.
ExpectedWarningTrait sets a custom error handler, that catches expected warnings and notices, without converting them
to exceptions. Code will continue to run.
After all other assertions succeed, the code will check if there are any expected warnings/notices that haven't been triggered.
In context of
mixed inContextOf(object $object, \Closure $function)The function is called in context of the given object. This allows to call private and protected methods and get or set private and protected properties.
Beware: You should only test via public methods and properties. When you're required to access private methods or properties to perform tests, something is likely wrong in the architecture of your code.
Consecutive calls
ConsecutiveTrait is a replacement for PHPUnit's withConsecutive method which was removed in PHPUnit 10.
