1.0.0 - PHPUnit 6 compatibility

With this release, we are dropping compatibility to PHPUnit 5 and below.
If you still need that, please use paratest 0.x (like 0.15.0 which supports phpunit 5).

1.0.0 doesn't mean Paratest is free of bugs, take a look at the issues for that. But paratest is used in production (like in productive development environments) and we try to keep backwards compatibility. While using semantic versioning, this major version gives us the power to express if changes break backwards compatibility or not by the version number itself and our users the power to expect working software by pinning to a major version number (>=1.0.0,<2.0.0).
