for those who have problem with writing long test methods name like me :)

ReadableTestNamesJUnitRunner.java

/**
 * Using this runner every test report (gui, cli, html) will print names of tests not as test method
 * names eg. "shouldBeLikeThatAndThat" but with spaces like "should be like that and that" for better
 * readability. <br/><br/>
 * 
 * <b>Usage</b>:<br/>
 * 
 * <pre>
 *    <b>{@literal @}RunWith(ReadableTestNamesJUnitRunner.class)</b>
 *    public class DateParserTest {
 *	
 *   	{@literal @}Test
 *	    public void shouldParseDateMonthYearWithSpacesBetweenValuesAndSingleDigitDay() {
 *         ...
 *      }
 *      
 *    }
 * </pre>
