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>

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=&quot;tier1&quot;</code>, but the latter is more tab-completion friendly.

<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.

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>

<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>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>

* Classes to support module descriptors and creating configurations of modules
* by means of resolution and service binding.
*
* <h2><a id="resolution">Resolution</a></h2>
*
* <p> Resolution is the process of computing the transitive closure of a set
* of root modules over a set of observable modules by resolving the
* dependences expressed by {@link
* java.lang.module.ModuleDescriptor.Requires requires} clauses.
* The <em>dependence graph</em> is augmented with edges that take account of
* implicitly declared dependences ({@code requires transitive}) to create a
* <em>readability graph</em>. The result of resolution is a {@link
* java.lang.module.Configuration Configuration} that encapsulates the
* readability graph. </p>
*
* <p> As an example, suppose we have the following observable modules: </p>
* <pre> {@code
* module m1 { requires m2; }
* module m2 { requires transitive m3; }
* module m3 { }
* module m4 { }
* } </pre>
*
* <p> If the module {@code m1} is resolved then the resulting configuration
* contains three modules ({@code m1}, {@code m2}, {@code m3}). The edges in
* its readability graph are: </p>
* <pre> {@code
* m1 --> m2 (meaning m1 reads m2)
* m1 --> m3
* m2 --> m3
* } </pre>
*
* <p> Resolution is an additive process. When computing the transitive closure
* then the dependence relation may include dependences on modules in {@link
* java.lang.module.Configuration#parents() parent} configurations. The result
* is a <em>relative configuration</em> that is relative to one or more parent
* configurations and where the readability graph may have edges from modules
* in the configuration to modules in parent configurations. </p>
*
* <p> As an example, suppose we have the following observable modules: </p>
* <pre> {@code
* module m1 { requires m2; requires java.xml; }
* module m2 { }
* } </pre>
*
* <p> If module {@code m1} is resolved with the configuration for the {@link
* java.lang.ModuleLayer#boot() boot} layer as the parent then the resulting
* configuration contains two modules ({@code m1}, {@code m2}). The edges in
* its readability graph are:
* <pre> {@code
* m1 --> m2
* m1 --> java.xml
* } </pre>
* where module {@code java.xml} is in the parent configuration. For
* simplicity, this example omits the implicitly declared dependence on the
* {@code java.base} module.
*
* <p> Requires clauses that are "{@code requires static}" express an optional
* dependence (except at compile-time). If a module declares that it
* "{@code requires static M}" then resolution does not search the observable
* modules for "{@code M}". However, if "{@code M}" is resolved (because resolution
* resolves a module that requires "{@code M}" without the {@link
* java.lang.module.ModuleDescriptor.Requires.Modifier#STATIC static} modifier)
* then the readability graph will contain read edges for each module that
* "{@code requires static M}". </p>
*
* <p> {@link java.lang.module.ModuleDescriptor#isAutomatic() Automatic} modules
* receive special treatment during resolution. Each automatic module is resolved
* as if it "{@code requires transitive}" all observable automatic modules and
* all automatic modules in the parent configurations. Each automatic module is
* resolved so that it reads all other modules in the resulting configuration and
* all modules in parent configurations. </p>
*
* <h2><a id="servicebinding">Service binding</a></h2>
*
* <p> Service binding is the process of augmenting a graph of resolved modules
* from the set of observable modules induced by the service-use dependence
* ({@code uses} and {@code provides} clauses). Any module that was not
* previously in the graph requires resolution to compute its transitive
* closure. Service binding is an iterative process in that adding a module
* that satisfies some service-use dependence may introduce new service-use
* dependences. </p>
*
* <p> Suppose we have the following observable modules: </p>
* <pre> {@code
* module m1 { exports p; uses p.S; }
* module m2 { requires m1; provides p.S with p2.S2; }
* module m3 { requires m1; requires m4; provides p.S with p3.S3; }
* module m4 { }
* } </pre>
*
* <p> If the module {@code m1} is resolved then the resulting graph of modules
* has one module ({@code m1}). If the graph is augmented with modules induced
* by the service-use dependence relation then the configuration will contain
* four modules ({@code m1}, {@code m2}, {@code m3}, {@code m4}). The edges in
* its readability graph are: </p>
* <pre> {@code
* m2 --> m1
* m3 --> m1
* m3 --> m4
* } </pre>
* <p> The edges in the conceptual service-use graph are: </p>
* <pre> {@code
* m1 --> m2 (meaning m1 uses a service that is provided by m2)
* m1 --> m3
* } </pre>
*
* <h2>General Exceptions</h2>
*
* <p> Unless otherwise noted, passing a {@code null} argument to a constructor
* or method of any class or interface in this package will cause a {@link
* java.lang.NullPointerException NullPointerException} to be thrown. Additionally,
* invoking a method with an array or collection containing a {@code null} element
* will cause a {@code NullPointerException}, unless otherwise specified. </p>
*
*
* <h1><a id="resolution">Resolution</a></h1>
*
* <p> Resolution is the process of computing how modules depend on each other.
* The process occurs at compile time and run time. </p>
*
* <p> Resolution is a two-step process. The first step recursively enumerates
* the 'requires' directives of a set of root modules. If all the enumerated
* modules are observable, then the second step computes their readability graph.
* The readability graph embodies how modules depend on each other, which in
* turn controls access across module boundaries. </p>
*
* <h2> Step 1: Recursive enumeration </h2>
*
* <p> Recursive enumeration takes a set of module names, looks up each of their
* module declarations, and for each module declaration, recursively enumerates:
*
* <ul>
* <li> <p> the module names given by the 'requires' directives with the
* 'transitive' modifier, and </p></li>
* <li> <p> at the discretion of the host system, the module names given by
* the 'requires' directives without the 'transitive' modifier. </p></li>
* </ul>
*
* <p> Module declarations are looked up in a set of observable modules. The set
* of observable modules is determined in an implementation specific manner. The
* set of observable modules may include modules with explicit declarations
* (that is, with a {@code module-info.java} source file or {@code module-info.class}
* file) and modules with implicit declarations (that is,
* <a href="ModuleFinder.html#automatic-modules">automatic modules</a>).
* Because an automatic module has no explicit module declaration, it has no
* 'requires' directives of its own, although its name may be given by a
* 'requires' directive of an explicit module declaration. </p>
* <p> The set of root modules, whose names are the initial input to this
* algorithm, is determined in an implementation specific manner. The set of
* root modules may include automatic modules. </p>
*
* <p> If at least one automatic module is enumerated by this algorithm, then
* every observable automatic module must be enumerated, regardless of whether
* any of their names are given by 'requires' directives of explicit module
* declarations. </p>
*
* <p> If any of the following conditions occur, then resolution fails:
* <ul>
* <li><p> Any root module is not observable. </p></li>
* <li><p> Any module whose name is given by a 'requires' directive with the
* 'transitive' modifier is not observable. </p></li>
* <li><p> At the discretion of the host system, any module whose name is given
* by a 'requires' directive without the 'transitive' modifier is not
* observable. </p></li>
* <li><p> The algorithm in this step enumerates the same module name twice. This
* indicates a cycle in the 'requires' directives, disregarding any 'transitive'
* modifiers. </p></li>
* </ul>
*
* <p> Otherwise, resolution proceeds to step 2. </p>
*
* <h2> Step 2: Computing the readability graph </h2>
*
* <p> A 'requires' directive (irrespective of 'transitive') expresses that
* one module depends on some other module. The effect of the 'transitive'
* modifier is to cause additional modules to also depend on the other module.
* If module M 'requires transitive N', then not only does M depend on N, but
* any module that depends on M also depends on N. This allows M to be
* refactored so that some or all of its content can be moved to a new module N
* without breaking modules that have a 'requires M' directive. </p>
*
* <p> Module dependencies are represented by the readability graph. The
* readability graph is a directed graph whose vertices are the modules
* enumerated in step 1 and whose edges represent readability between pairs of
* modules. The edges are specified as follows:
*
* <p> First, readability is determined by the 'requires' directives of the
* enumerated modules, disregarding any 'transitive' modifiers:
*
* <ul>
* <li><p> For each enumerated module A that 'requires' B: A "reads" B. </p></li>
* <li><p> For each enumerated module X that is automatic: X "reads" every
* other enumerated module (it is "as if" an automatic module has 'requires'
* directives for every other enumerated module). </p></li>
* </ul>
*
* <p> Second, readability is augmented to account for 'transitive' modifiers:
* <ul>
* <li> <p> For each enumerated module A that "reads" B: </p>
* <ul>
* <li><p> If B 'requires transitive' C, then A "reads" C as well as B. This
* augmentation is recursive: since A "reads" C, if C 'requires transitive'
* D, then A "reads" D as well as C and B. </p></li>
* <li><p> If B is an automatic module, then A "reads" every other enumerated
* automatic module. (It is "as if" an automatic module has 'requires transitive'
* directives for every other enumerated automatic module).</p> </li>
* </ul>
* </li>
* </ul>
*
* <p> Finally, every module "reads" itself. </p>
*
* <p> If any of the following conditions occur in the readability graph, then
* resolution fails:
* <ul>
* <li><p> A module "reads" two or more modules with the same name. This includes
* the case where a module "reads" another with the same name as itself. </p></li>
* <li><p> Two or more modules export a package with the same name to a module
* that "reads" both. This includes the case where a module M containing package
* p "reads" another module that exports p to M. </p></li>
* <li><p> A module M declares that it 'uses p.S' or 'provides p.S with ...' but
* package p is neither in module M nor exported to M by any module that M
* "reads". </p></li>
* </ul>
* <p> Otherwise, resolution succeeds, and the result of resolution is the
* readability graph.
*
* <h2> Root modules </h2>
*
* <p> The set of root modules at compile-time is usually the set of modules
* being compiled. At run-time, the set of root modules is usually the
* application module specified to the 'java' launcher. When compiling code in
* the unnamed module, or at run-time when the main application class is loaded
* from the class path, then the default set of root modules is implementation
* specific (In the JDK implementation it is the module "java.se", if observable,
* and every observable module that exports an API). </p>
*
* <h2> Observable modules </h2>
*
* <p> The set of observable modules at both compile-time and run-time is
* determined by searching several different paths, and also by searching
* the compiled modules built in to the environment. The search order is as
* follows: </p>
*
* <ol>
* <li><p> At compile time only, the compilation module path. This path
* contains module definitions in source form. </p></li>
*
* <li><p> The upgrade module path. This path contains compiled definitions of
* modules that will be observed in preference to the compiled definitions of
* any <i>upgradeable modules</i> that are present in (3) and (4). See the Java
* SE Platform for the designation of which standard modules are upgradeable.
* </p></li>
*
* <li><p> The system modules, which are the compiled definitions built in to
* the environment. </p></li>
*
* <li><p> The application module path. This path contains compiled definitions
* of library and application modules. </p></li>
*
* </ol>
*
* <h2> 'requires' directives with 'static' modifier </h2>
*
* <p> 'requires' directives that have the 'static' modifier express an optional
* dependence at run time. If a module declares that it 'requires static M' then
* resolution does not search the observable modules for M to satisfy the dependency.
* However, if M is recursively enumerated at step 1 then all modules that are
* enumerated and `requires static M` will read M. </p>
*
* <h2> Completeness </h2>
*
* <p> Resolution may be partial at compile-time in that the complete transitive
* closure may not be required to compile a set of modules. Minimally, the
* readability graph that is constructed and validated at compile-time includes
* the modules being compiled, their direct dependences, and all implicitly
* declared dependences (requires transitive). </p>
*
* <p> At run-time, resolution is an additive process. The recursive enumeration
* at step 1 may be relative to previous resolutions so that a root module,
* or a module named in a 'requires' directive, is not enumerated when it was
* enumerated by a previous (or parent) resolution. The readability graph that
* is the result of resolution may therefore have a vertex for a module enumerated
* in step 1 but with an edge to represent that the module reads a module that
* was enumerated by previous (or parent) resolution. </p>
