Infection - Include Interceptor Stream Wrapper

It's a Stream Wrapper that wraps a file:// protocol and allows overriding content of any (auto) loaded file, including files autoloaded by Composer package manager.

How it works

If you want to replace the content of the file whenever it's loaded (by executing include '/path/to/file.php, by calling file_get_contents('/path/to/file.php'), etc.), you need to register IncludeInterceptor before loading original file:

use Infection\StreamWrapper\IncludeInterceptor;

IncludeInterceptor::intercept('/path/to/original_file.php', '/path/to/replacement_file.php');

After enabling IncludeInterceptor, content of the replacement_file.php will be loaded instead of content of the original_file.php.

Use cases

  • This Stream Wrapper is used to replace the original file with the Mutant in Infection Mutation Testing Framework
  • The same approach is used in the dg/bypass-finals package that allows to mock final classes, by overriding original content and removing final keyword in runtime
