Test enhancement (#6)

- Set multiple PHPUnit versions to support different PHP versions.
- Set the nightly test and accept this can be failed in Travis CI build.
- Add the php-7.2 test in Travis CI build.
- Use the class-based PHPUnit namespace to support the stable PHPUnit version.
- Add more tests.

Thanks to @peter279k 👍
