+<h2 id="using-the-run-test-framework">Using the run-test framework</h2>
+<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>Some example command-lines:</p>
+<pre><code>$ make run-test-tier1
+$ make run-test-jdk_lang JTREG="JOBS=8"
+$ make run-test TEST=jdk_lang
+$ make run-test-only TEST="gtest:LogTagSet gtest:LogTagSetDescriptions" GTEST="REPEAT=-1"
+$ make run-test TEST="hotspot/test:hotspot_gc" JTREG="JOBS=1;TIMEOUT=8;VM_OTIONS=-XshowSettings -Xlog:gc+ref=debug"
+$ make run-test TEST="jtreg:hotspot/test:hotspot_gc hotspot/test/native_sanity/JniVersion.java"</code></pre>
+<h2 id="test-selection">Test selection</h2>
+<p>All functionality is available using the run-test 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, run-test-only 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 run-test-tier1</code> is equivalent to <code>make run-test TEST="tier1"</code>, but the latter is more tab-completion friendly. For more complex test runs, the <code>run-test TEST="x"</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. As an example, <code>:tier1</code> will expand to <code>jtreg:jdk/test:tier1 jtreg:langtools/test:tier1 jtreg:nashorn/test:tier1 jtreg:jaxp/test:tier1</code>. You can always submit a list of fully qualified test descriptors in the <code>TEST</code> variable if you want to shortcut the parser.</p>
+<h3 id="jtreg">JTreg</h3>
+<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/test:tier1</code>, <code>jdk/test:jdk_util</code>.</p>
+<p>When specified without a test root, all matching groups from all tests roots will be added. Otherwise, only the group from the specified test root will be added.</p>
+<p>Individual JTreg tests or directories containing JTreg tests can also be specified, like <code>hotspot/test/native_sanity/JniVersion.java</code> or <code>hotspot/test/native_sanity</code>. You can also specify an absolute path, to point to a JTreg test outside the source tree.</p>
+<p>As long as the test groups or test paths can be uniquely resolved, you do not need to enter the <code>jtreg:</code> prefix. If this is not possible, or if you want to use a fully qualified test descriptor, add <code>jtreg:</code>, e.g. <code>jtreg:hotspot/test/native_sanity</code>.</p>
+<h3 id="gtest">Gtest</h3>
+<p>Since the Hotspot Gtest suite is so quick, the default is to run all tests. This is specified by just <code>gtest</code>, or as a fully qualified test descriptor <code>gtest:all</code>.</p>
+<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>
+<h2 id="test-results-and-summary">Test results and summary</h2>
+<p>At the end of the test run, a summary of all tests run will be presented. This will have a consistent look, regardless of what test suites were used. This is a sample summary:</p>
+<pre><code>==============================
+Test summary
+==============================
+ TEST TOTAL PASS FAIL ERROR
+>> jtreg:jdk/test:tier1 1867 1865 2 0 <<
+ jtreg:langtools/test:tier1 4711 4711 0 0
+ jtreg:nashorn/test:tier1 133 133 0 0
+==============================
+TEST FAILURE</code></pre>
+<p>Tests where the number of TOTAL tests does not equal the number of PASSed tests will be considered a test failure. These are marked with the <code>>> ... <<</code> marker for easy identification.</p>
+<p>The classification of non-passed tests differs a bit between test suites. In the summary, ERROR is used as a catch-all for tests that neither passed nor are classified as failed by the framework. This might indicate test framework error, timeout or other problems.</p>
+<p>In case of test failures, <code>make run-test</code> will exit with a non-zero exit value.</p>
+<p>All tests have their result stored in <code>build/$BUILD/test-result/$TEST_ID</code>, where TEST_ID is a path-safe conversion from the fully qualified test descriptor, e.g. for <code>jtreg:jdk/test:tier1</code> the TEST_ID is <code>jtreg_jdk_test_tier1</code>. This path is also printed in the log at the end of the test run.</p>
+<p>Additional work data is stored in <code>build/$BUILD/test-support/$TEST_ID</code>. For some frameworks, this directory might contain information that is useful in determining the cause of a failed test.</p>
+<h2 id="test-suite-control">Test suite control</h2>
+<p>It is possible to control various aspects of the test suites using make control variables.</p>
+<p>These variables use a keyword=value approach to allow multiple values to be set. So, for instance, <code>JTREG="JOBS=1;TIMEOUT=8"</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="TMIEOUT=8"</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="...;..."</code>.

+<p>(Other ways are possible, e.g. using backslash: <code>JTREG=JOBS=1\;TIMEOUT=8</code>. Also, as a special technique, the string <code>%20</code> will be replaced with space for certain options, e.g. <code>JTREG=VM_OTIONS=-XshowSettings%20-Xlog:gc+ref=debug</code>. This can be useful if you have layers of scripts and have trouble getting proper quoting of command line arguments through.)</p>

+ $ make run-test TEST="jtreg:hotspot/test:hotspot_gc hotspot/test/native_sanity/JniVersion.java"
+
+## Test selection
+
+All functionality is available using the run-test make target. In this use
+case, the test or tests to be executed is controlled using the `TEST` variable.
+To speed up subsequent test runs with no source code changes, run-test-only can
+be used instead, which do not depend on the source and test image build.
+
+For some common top-level tests, direct make targets have been generated. This

+TEST="tier1"`, but the latter is more tab-completion friendly. For more complex
+test runs, the `run-test TEST="x"` solution needs to be used.
+
+The test specifications given in `TEST` is parsed into fully qualified test
+descriptors, which clearly and unambigously show which tests will be run. As an
+example, `:tier1` will expand to `jtreg:jdk/test:tier1
+jtreg:langtools/test:tier1 jtreg:nashorn/test:tier1 jtreg:jaxp/test:tier1`. You
+can always submit a list of fully qualified test descriptors in the `TEST`
+variable if you want to shortcut the parser.

+
+When specified without a test root, all matching groups from all tests roots

+specified, like `hotspot/test/native_sanity/JniVersion.java` or
+`hotspot/test/native_sanity`. You can also specify an absolute path, to point
+to a JTreg test outside the source tree.
+
+As long as the test groups or test paths can be uniquely resolved, you do not
+need to enter the `jtreg:` prefix. If this is not possible, or if you want to
+use a fully qualified test descriptor, add `jtreg:`, e.g.
+`jtreg:hotspot/test/native_sanity`.
+
+### Gtest
+
+Since the Hotspot Gtest suite is so quick, the default is to run all tests.
+This is specified by just `gtest`, or as a fully qualified test descriptor
+`gtest:all`.
+
+If you want, you can single out an individual test or a group of tests, for

+The test concurrency (`-concurrency`).
+
+Defaults to TEST_JOBS (if set by `--with-test-jobs=`), otherwise it defaults to

+Enable asserts (`-ea -esa`, or none).
+
+Set to `true` or `false`. If true, adds `-ea -esa`. Defaults to true, except

+
+#### VERBOSE
+The verbosity level (`-verbose`).

+What test data to retain (`-retain`).
+
+Defaults to `fail,error`.
+
+#### MAX_MEM
+Limit memory consumption (`-Xmx` and `-vmoption:-Xmx`, or none).
+
+Limit memory consumption for JTreg test framework and VM under test. Set to 0
