 <p>If you want, you can single out an individual test or a group of tests, for instance <code>gtest:LogDecorations</code> or <code>gtest:LogDecorations.level_test_vm</code>. This can be particularly useful if you want to run a shaky test repeatedly.</p>
 <p>For Gtest, there is a separate test suite for each JVM variant. The JVM variant is defined by adding <code>/&lt;variant&gt;</code> to the test descriptor, e.g. <code>gtest:Log/client</code>. If you specify no variant, gtest will run once for each JVM variant present (e.g. server, client). So if you only have the server JVM present, then <code>gtest:all</code> will be equivalent to <code>gtest:all/server</code>.</p>
