What's new in Infection 0.15.0

Sep 29, 2019

Release: https://github.com/infection/infection/releases/tag/0.15.0

BC Breaks

We changed a path for JUnit report expected by Infection when existing coverage is provided.

Before:

build/coverage/phpunit.junit.xml

After:

build/coverage/junit.xml

New features and enhancements

Codeception Test Framework Support

Codeception

We are happy to announce Codeception + Infection integration, one of the most upvoted feature request.

Let’s bring a new level of tests quality for Codeception users!

Log mutation results directly to stdout/stderr

PHP 7.4 compatibility

Infection is now fully compatible with PHP 7.4.

New Symfony versions compatibility

Infection is now fully compatible with Symfony 4.4 and Symfony 5.0.

Allow to enable pcov with --initial-tests-php-options

Now, you can enable pcov for Initial Tests run in Infection to generate coverage:

$ infection --initial-tests-php-options='-d extension=pcov.so'

See /guide/command-line-options.html#initial-tests-php-options

Version number under ASCII banner

Little, but useful enhancement: we’ve added a version number right under Infection ASCII banner (like Composer does it):

$ infection --threads=4

Infection - PHP Mutation Testing Framework 0.15.0@b96e312cb6726862089f63cbc6557b62fe29f4c0

New Mutators

clone removal

$now = new \DateTime();
- $cloned = clone $now;
+ $cloned = $now;

$cloned->modify('+1 day');

This mutator helps to find unnecessary or untested cloning.

UnwrapStrReplace

This mutator takes the third argument of str_replace() function and assigns it to the variable.

- $a = str_replace('Afternoon', 'Evening' ,'Good Afternoon!');
+ $a = 'Good Afternoon!';

Enjoy!
