WP-CLI install-wp-tests required files cannot be found

I’m following this tutorial: https://pippinsplugins.com/unit-tests-wordpress-plugins-setting-up-testing-suite/
I got to the point where I ran sh bin/install-wp-tests.sh hl_market_tracker_tests root '' localhost latest and it generated a %Temp%\wordpress and %Temp%\wordpress-tests-lib folder. However, when I run phpunit,

I got

Fatal error: require_once(): Failed opening required '/tmp/wordpress//wp-includes/class-phpmailer.php' (include_path='C:\xampp\php\PEAR') in C:\Users\Duy\AppData\Local\Temp\wordpress-tests-lib\includes\mock-mailer.php on line 2

The reason for that was that
C:\Users\Duy\AppData\Local\Temp\wordpress-tests-lib\includes\mock-mailer.php on line 2
has require_once( ABSPATH . ‘/wp-includes/class-phpmailer.php’ );
However, class-phpmailer was in wordpress/wp-includes and it was trying to find it in /tmp/wordpress//wp-includes/class-phpmailer.php

If I changed ABSPATH in mock-mailer to have the correct path, then it will work. Is this something wrong with the library? I’m trying to run PHPUnit to test my WP plugin and I have XAAMP on Windows. Thank you.
