What happened?

According to the doc, you can call command() and all output is captured. However, I have a command that uses CLI::write() to output various messages as the command is executed and those outputs are still written to the console. My use case is that I'm writing a test script, which calls the command() function, and it generates output.

Steps to Reproduce

1. write a command that just does a CLI::write('hello world') to the console
2. write a test script that calls command() with the command
3. run tests and see that hello world shows up in the testing output.

Expected Output

I'm expecting no output unless I'm manually outputting the return value from the command() call.

Anything else?

No response

Oh, cool! That should help, thanks! Is this still an issue, though, since the output isn't captured as documented?

No, there is no issue.

When you run a command using command('whatever'), its output is printed directly to STDOUT.
In a normal web request or CLI execution, this works fine. However, in a testing environment, you need to capture this output for assertions because PHPUnit does not naturally capture STDOUT.

That makes sense ... thank you! Thanks also for the quick triaging and responses! :)
