### Question:
VersionUtil { public static String getVersionSpec(String version, String enforceVersion) { String spec = enforceVersion; if (enforceVersion == null || Boolean.parseBoolean(enforceVersion)) { spec = '[' + version + ']'; } else if (Boolean.FALSE.toString().equalsIgnoreCase(enforceVersion)) { spec = MATCH_ALL; } else if (!VersionUtil.isWithin(version, enforceVersion)) { LOGGER.warn(VERSION_NOT_IN_RANGE, version, enforceVersion); } return spec; } private  VersionUtil(); static String getVersionSpec(String version, String enforceVersion); static boolean isWithin(String version, String versionSpec);  }### Answer:
@Test public void testGetVersionSpec_EnforceVersionTrue() { assertThat(VersionUtil.getVersionSpec("2.0.0", "true")).isEqualTo("[2.0.0]"); }
@Test public void testGetVersionSpec_EnforceVersionFalse() { assertThat(VersionUtil.getVersionSpec("2.0.0", "false")).isEqualTo("[0,]"); }
@Test public void testGetVersionSpec_EnforceVersionRange() { assertThat(VersionUtil.getVersionSpec("2.0.0", "[1.2,2.5]")).isEqualTo("[1.2,2.5]"); }
@Test public void testGetVersionSpec_EnforceVersionRangeNotWithin() { assertThat(VersionUtil.getVersionSpec("1.0", "[1.2,2.5]")).isEqualTo("[1.2,2.5]"); }
