<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 JTReg tests, <code>configure</code> needs to know where to find the JTReg test framework. If it is not picked up automatically by configure, use the <code>--with-jtreg=&lt;path to jtreg home&gt;</code> option to point to the JTReg framework. Note that this option should point to the JTReg home, i.e. the top directory, containing <code>lib/jtreg.jar</code> etc. (An alternative is to set the <code>JT_HOME</code> environment variable to point to the JTReg home before running <code>configure</code>.)</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>

<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=&quot;tier1&quot;</code>, but the latter is more tab-completion friendly. For more complex test runs, the <code>test TEST=&quot;x&quot;</code> solution needs to be used.</p>

<p>JTReg test groups can be specified either without a test root, e.g. <code>:tier1</code> (or <code>tier1</code>, the initial colon is optional), or with, e.g. <code>hotspot:tier1</code>, <code>test/jdk:jdk_util</code> or <code>$(TOPDIR)/test/hotspot/jtreg:hotspot_all</code>. The test root can be specified either as an absolute path, or a path relative to the JDK top directory, or the <code>test</code> directory. For simplicity, the hotspot JTReg test root, which really is <code>hotspot/jtreg</code> can be abbreviated as just <code>hotspot</code>.</p>

Just like for test root selection, you can either specify an absolute path (which can even point to JTReg tests outside the source tree), or a path relative to either the JDK top directory or the <code>test</code> directory. <code>hotspot</code> can be used as an alias for <code>hotspot/jtreg</code> here as well.</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>

<p>These variables use a keyword=value approach to allow multiple values to be set. So, for instance, <code>JTREG=&quot;JOBS=1;TIMEOUT=8&quot;</code> will set the JTReg concurrency level to 1 and the timeout factor to 8. This is equivalent to setting <code>JTREG_JOBS=1 JTREG_TIMEOUT=8</code>, but using the keyword format means that the <code>JTREG</code> variable is parsed and verified for correctness, so <code>JTREG=&quot;TMIEOUT=8&quot;</code> would give an error, while <code>JTREG_TMIEOUT=8</code> would just pass unnoticed.</p>

<p>To separate multiple keyword=value pairs, use <code>;</code> (semicolon). Since the shell normally eats <code>;</code>, the recommended usage is to write the assignment inside qoutes, e.g. <code>JTREG=&quot;...;...&quot;</code>. This will also make sure spaces are preserved, as in <code>JTREG=&quot;VM_OPTIONS=-XshowSettings -Xlog:gc+ref=debug&quot;</code>.</p>

<p>If your locale is non-US, some tests are likely to fail. To work around this you can set the locale to US. On Unix platforms simply setting <code>LANG=&quot;en_US&quot;</code> in the environment before running tests should work. On Windows, setting <code>JTREG=&quot;VM_OPTIONS=-Duser.language=en -Duser.country=US&quot;</code> helps for most, but not all test cases. For example:</p>
