Laravel team has recently announced that they are moving from a 6 month major release cycle to 12 month major release cycle. This is due to many users feeling that versions were being released frequently since adopting the "semantic versioning" standard even though the cycle speed stayed the same.
And because of this decision, the team decided to backport parallel testing to Laravel 8, which was supposed to be a major feature of the Laravel 9 release.
Developers like us can now enjoy the benefits of faster running tests as of Laravel 8.25!

Here's a preview of tests in one of my major projects before and after implementing parallel test.
As you can see, that's about 50% increase in time it took to complete the entire test suite and more than 80% reduction on memory usage.
I don't know about you but that is insane!
