This PR for adding unit test for isNoneBlank method in stringUtils

I'm contemplating about establishing a well-defined testing structure for Strings,

1. For test data : We can use a string randomizer to output a random string with a defined rule (blank, contains [aA-Zz] and [0-9] and [any special char], or contains only the defined characters we input ( only spaces , etc ), a partial-buildable string value might be necessary.
2. For code structure: I'm considering on this template:

@Test
    public void testDummy() {
        int length = 10;
        boolean useLetters = true;
        boolean useNumbers = false;
        String generatedString = RandomStringUtils.random(length, useLetters, useNumbers);

        final Function<String, Boolean> testNoneBlank = StringUtils::isNoneBlank;
        assertTrue(testNoneBlank.apply(generatedString));
    }

RandomStringUtils is imported from apache-commons-lang

I'm planning on BaseTest.java, TestCase.java classes as well.

sth like : https://examples.javacodegeeks.com/java-development/core-java/junit/junit-setup-teardown-example/ to be more readable and maintainable

We can make use of this, and better serve for other string-related method testing. What's your suggestion?

It's good for me. So let's follow your suggestion
