Laravel PHP Unit - Keep output from tests

TLDR;

How can I run php unit tests in Laravel 7 without removing all output that is emitted during the execution of a test?

Full question:

I'm trying to run a few tests in Laravel 7 with PHPUnit 8.5.

In these tests, I am dumping information as the test isn't simply pass or fail, but dumping further information to help improve page load efficiency. For this reason, I am dumping this data into the terminal.

Data is dumped into the terminal while the test is running, but once the test has been completed, the information is removed.

Problem: I would like to prevent this output from being removed.

Attempted solutions that did not work:

• --verbose
• --debug
• turn on strict mode within phpunit
• dump information using the fwrite() method
• ob_flush()
• print_r()
• print()

Note: I realise that this topic has been discussed previously, but none of those methods are currently working.
