Do not limit number of columns to 80 on non-interactive TTY

[borys-p]

Q	A
PHPUnit version	10.3.5
PHP version	8.2.8
Installation Method	Composer

Summary

I'm upgrading to version 10 and ran across a relatively minor, but still valid issue. We're running unit tests in a Docker container, in Jenkins, which is not allocating a TTY. This causes phpUnit to revert to the default width of 80 columns, even though we can safely display >200 in our environment.

Current behavior

phpUnit assumes that a non-interactive TTY always has a width of 80 columns, even though this is rarely the case nowadays. In our case we could safely increase that number to over 200 columns and with a few thousand tests our current output is unnecessarily long.

How to reproduce

Define columns="200" in phpunit.xml and run the tests inside a non-TTY environment (e.g., docker exec container-name phpunit). You will notice that the output width is limited to just 80 characters, as Console::isInteractive() returns 80.

Expected behavior

The ability to define the maximum console width, with 80 being the default. Ideally, via a configuration setting, but it could be also a property that can be changed by an extension.

I can see a possible workaround by leveraging the loadFrom() method that does not override the values, but that's just an ugly hack, not addressing the actual issue.

Amazing, thank you very much!
