Using version ^7.0 for phpunit/phpunit-selenium

Your requirements could not be resolved to an installable set of packages.
Problem 1
- Installation request for phpunit/phpunit-selenium ^7.0 -> satisfiable by phpunit/phpunit-selenium[7.0.0].
- phpunit/phpunit-selenium 7.0.0 requires phpunit/phpunit >=7.0,<8.0 -> satisfiable by phpunit/phpunit[7.0.0, 7.0.1, 7.0.2, 7.0.3, 7.1.0, 7.1.1, 7.1.2, 7.1.3, 7.1.4, 7.1.5, 7.2.0, 7.2.1, 7.2.2, 7.2.3, 7.2.4, 7.2.5, 7.2.6, 7.2.7, 7.3.0, 7.3.1, 7.3.2, 7.3.3, 7.3.4, 7.3.5, 7.4.0, 7.4.1, 7.4.2, 7.4.3, 7.4.4, 7.4.5, 7.5.0, 7.5.1, 7.5.10, 7.5.11, 7.5.12, 7.5.13, 7.5.14, 7.5.15, 7.5.16, 7.5.2, 7.5.3, 7.5.4, 7.5.5, 7.5.6, 7.5.7, 7.5.8, 7.5.9, 7.5.x-dev] but these conflict with your requirements or minimum-stability.
Installation failed, reverting ./composer.json to its original content.
Before installing selenium, I tried to install PHPUnit and it installed successfully.
I also move the selenium jar file to usr/local/bin folder then run it.
I didn't find any solution. Can anyone help me out for this?
