This is the JUnit 5 solution to cover all kinds of inputs provided to find the reversing each word from a given sentence. This Unit test executes tests for the ‘ParseEachWord’ function available in the class ‘SumofDgtsInAlphanumericJ8’.

package pack1;

import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.DisplayName;
import org.junit.jupiter.api.Test;

class JunitTestReversingEachWordJ8 {

	ReversingEachWord_Using_StringBuffer REWUStrB;
	ReversingEachWord_Using_String REWUStr;
	ReversingEachWord_Using_LambdaExp REWULamda;
	ReversingEachWord_Using_Stream REWUStream;

	@BeforeEach
	void setUp() throws Exception {
		REWUStrB = new ReversingEachWord_Using_StringBuffer();
		REWUStr = new ReversingEachWord_Using_String();
		REWULamda = new ReversingEachWord_Using_LambdaExp();
		REWUStream = new ReversingEachWord_Using_Stream();
	}

	@Test
	@DisplayName("Positive inputs - Exp value and Actual matches")
	void test1() {
		Assertions.assertEquals("4tinuJ dna 5tinuJ ", REWUStrB.ParseEachWord("Junit4 and Junit5").toString());
		Assertions.assertEquals("7avaJ dna 71avaJ ", REWUStr.ParseEachWord("Java7 and Java17").toString());
		Assertions.assertEquals("42.0.8LQSyM dna 02.0.8LQSyM ",
				REWULamda.ParseEachWord("MySQL8.0.24 and MySQL8.0.20").toString());
		Assertions.assertEquals("[8vtacmoT, dna, 9vtacmoT]",
				REWUStream.ParseEachWord("Tomcatv8 and Tomcatv9").toString());
	}

	@Test
	@DisplayName("Negative inputs  - Exp value and Actual does not matches")
	void test2() {
		Assertions.assertNotEquals("Junit4 dna 5tinuJ", REWUStrB.ParseEachWord("Junit4 and Junit5").toString());
		Assertions.assertNotEquals("Java17 dna 71avaJ ", REWUStr.ParseEachWord("Java7 and Java17").toString());
		Assertions.assertNotEquals("MySQL8.0.20 dna 02.0.8LQSyM ",
				REWULamda.ParseEachWord("MySQL8.0.24 and MySQL8.0.20").toString());
		Assertions.assertNotEquals("[Tomcatv10, dna, 9vtacmoT]",
				REWUStream.ParseEachWord("Tomcatv8 and Tomcatv9").toString());
	}

	@Test
	@DisplayName("Null inputs")
	void test3() {
		Assertions.assertEquals("", REWUStrB.ParseEachWord(null).toString());
		Assertions.assertEquals("", REWUStr.ParseEachWord(null).toString());
		Assertions.assertEquals("", REWULamda.ParseEachWord(null).toString());
		Assertions.assertEquals("[]", REWUStream.ParseEachWord(null).toString());
	}

	@Test
	@DisplayName("Empty inputs")
	void test4() {
		Assertions.assertEquals("", REWUStrB.ParseEachWord("").toString());
		Assertions.assertEquals(" ", REWUStr.ParseEachWord("").toString());
		Assertions.assertEquals("", REWULamda.ParseEachWord("").toString());
		Assertions.assertEquals("[]", REWUStream.ParseEachWord("").toString());
	}

	@Test
	@DisplayName("Input only a String - Exp value and Actual matches")
	void test5() {
		Assertions.assertNotEquals("evitisoP", REWUStrB.ParseEachWord("Positive").toString());
		Assertions.assertNotEquals("SoiranecS", REWUStr.ParseEachWord("ScenarioS").toString());
		Assertions.assertNotEquals("evitageN", REWULamda.ParseEachWord("Negative").toString());
		Assertions.assertNotEquals("stupnIetadilaV", REWUStream.ParseEachWord("ValidateInputs").toString());
	}

	@Test
	@DisplayName("Input only an Alphanumeric - Exp value and Actual matches")
	void test6() {
		Assertions.assertNotEquals("$nj$!($8J", REWUStrB.ParseEachWord("J8$(!$jn$").toString());
		Assertions.assertNotEquals("qA13~!|]{", REWUStr.ParseEachWord("{]|!~31Aq").toString());
		Assertions.assertNotEquals("Wa/`+57*", REWULamda.ParseEachWord("*75+`/aW").toString());
		Assertions.assertNotEquals("1@54L^*&X", REWUStream.ParseEachWord("X&*^L45@1").toString());
	}
}
