Informations about the package assert-throws

cspray/assert-throws

Composer is the only supported method to install this package.

Detailed Guide

PHPUnit provides a reasonable way to test for expected exceptions out-of-the-box. For most situations, the PHPUnit provided methods should be sufficient. However, there are scenarios where you might need to test exception throwing code in a way not readily available in PHPUnit. Examples of this include code where you want to test the previous exception or if the exception includes domain specific information. It is in these situations that this library is most appropriate.

All the assertions provided by this library takes a callable that is expected to throw an exception. If an exception is not thrown a PHPUnit\Framework\ExpectationFailedException will be thrown resulting in a test failure. Otherwise, the thrown exception will be returned for additional assertions.

The following static methods are available on the Cspray\AssertThrows\ThrowableAssert class:

In addition to the ThrowableAssert class with static methods there are global functions available:

As well as a trait to use in your PHPUnit\Framework\TestCase implementations:

Which method you use is a personal preference. Ultimately, all examples utilize the static methods available in the ThrowableAssert class.
