Test 1:

Use

grep -A3 'new single_button' -R . | grep -B2 'true\|false' 

You should not see any single_button constructor with a fourth argument being a boolean.

Test 2 (optional)

To test if the argument has been fully replaced in the core code, I used a script for phpcs.

1. Create a folder MyCustomStandard/Snif/Classes in the moodle src directory

   mkdir -p MyCustomStandard/Sniffs/Classes

2. Add the SingleButtonFourthArgBooleanSniff.php
3. Add the ruleset.xml in the moodle src directory
4. Run phpcs

   phpcs --standard=ruleset.xml --extensions=php .

5. Ensure there is no error detected

Code verified against automated checks.
