### Question:
AuthBrowser { public AuthBrowserVersionRange getVersionRange() { return versionRange; } AuthBrowser(final String packageName, final Set<String> signatures,
                    final boolean useCustomTab, final AuthBrowserVersionRange versionRange); String getPackageName(); Set<String> getSignatures(); boolean isUseCustomTab(); AuthBrowserVersionRange getVersionRange();  }### Answer:
@Test public void testVersionRange() { Assert.assertEquals(null, authBrowser.getVersionRange().getLowerBoundary()); Assert.assertEquals(null, authBrowser.getVersionRange().getUpperBoundary()); }
