### Question:
WadlHelper { public static final boolean isVersion(final String step) { return step.toLowerCase().equals("v1"); } private  WadlHelper(); static List<Param> getRequestParams(final Method method); static final String computeId(final Method method, final Resource resource, final Resources resources,
            final Application app, final Stack<Resource> ancestors); static final String titleCase(final String text); static final List<T> reverse(final List<T> strings); static final boolean isVersion(final String step); static final String parseTemplateParam(final String step); static final List<String> toSteps(final Resource resource, final Stack<Resource> ancestors); static final boolean isTemplateParam(final String step);  }### Answer:
@Test public void testIsVersion() throws Exception { String versionString = "v1"; String versionStringUpperCase = "V1"; String nonVersionString = "blah"; assertTrue(WadlHelper.isVersion(versionString)); assertTrue(WadlHelper.isVersion(versionStringUpperCase)); assertFalse(WadlHelper.isVersion(nonVersionString)); }
