 <p>You will need two copies of your toolchain, one which generates output that can run on the target system (the normal, or <em>target</em>, toolchain), and one that generates output that can run on the build system (the <em>build</em> toolchain).

 <p>This new way of running tests is developer-centric. It assumes that you have built a JDK locally and want to test it. Running common test targets is simple, and more complex ad-hoc combination of tests is possible. The user interface is forgiving, and clearly report errors it cannot resolve.</p>
 <p>The main target <code>test</code> uses the jdk-image as the tested product. There is also an alternate target <code>exploded-test</code> that uses the exploded image instead. Not all tests will run successfully on the exploded image, but using this target can greatly improve rebuild times for certain workflows.</p>
 <p>Previously, <code>make test</code> was used to invoke an old system for running tests, and <code>make run-test</code> was used for the new test framework. For backward compatibility with scripts and muscle memory, <code>run-test</code> (and variants like <code>exploded-run-test</code> or <code>run-test-tier1</code>) are kept as aliases.</p>

 <p>To be able to run microbenchmarks, <code>configure</code> needs to know where to find the JMH dependency. Use <code>--with-jmh=&lt;path to JMH jars&gt;</code> to point to a directory containing the core JMH and transitive dependencies. The recommended dependencies can be retrieved by running <code>sh make/devkit/createJMHBundle.sh</code>, after which <code>--with-jmh=build/jmh/jars</code> should work.</p>
 <h2 id="test-selection">Test selection</h2>
 <p>All functionality is available using the <code>test</code> make target. In this use case, the test or tests to be executed is controlled using the <code>TEST</code> variable. To speed up subsequent test runs with no source code changes, <code>test-only</code> can be used instead, which do not depend on the source and test image build.</p>
-<p>For some common top-level tests, direct make targets have been generated. This includes all JTReg test groups, the hotspot gtest, and custom tests (if present). This means that <code>make test-tier1</code> is equivalent to <code>make test TEST="tier1"</code>, but the latter is more tab-completion friendly. For more complex test runs, the <code>test TEST="x"</code> solution needs to be used.</p>

For more complex test runs, the <code>test TEST=&quot;x&quot;</code> solution needs to be used.</p>
 <p>The test specifications given in <code>TEST</code> is parsed into fully qualified test descriptors, which clearly and unambigously show which tests will be run.
