thank you, Travis seems failing. if you could paste in screenshot of tests passing then we are good to go.
(later we can move to GitHub actions for tests)

I'm sorry.

[adhocore]

For compatibility with differences between php and phpunit versions, I remove the method of setUp.
The build of action has passed.

--protected function setUp()
++protected function setUp(): void
{
}
