In addition, JUnit produces text and <span class="caps">XML</span> report files in the project’s <code>reports/junit</code> directory. You can use that to get around too-much-stuff-in-my-console, or when using an automated test system.</p> +<p>In addition, you can get a consolidated <span class="caps">XML</span> or <span class="caps">HTML</span> report by running the <code>junit:report</code> task. For example:</p> +<figure class="highlight"><pre><code class="language-sh" data-lang="sh"><span class="nv">$ </span>buildr <span class="nb">test </span>junit:report <span class="nb">test</span><span class="o">=</span>all +<span class="nv">$ </span>firefox report/junit/html/index.html</code></pre></figure><p>The <code>junit:report</code> task generates a report from all tests run so far. If you run tests in a couple of projects, it will generate a report only for these two projects. The example above runs tests in all the projects before generating the reports.</p> +<p>You can use the <code>build.yaml</code> settings file to specify a particular version of JUnit or JMock. For example, to force your build to use JUnit version 4.4 and JMock 2.0:</p> +<figure class="highlight"><pre><code class="language-yaml" data-lang="yaml"><span class="l-Scalar-Plain">junit</span><span class="p-Indicator">:</span> <span class="l-Scalar-Plain">4.4</span> +<span class="l-Scalar-Plain">jmock</span><span class="p-Indicator">:</span> <span class="l-Scalar-Plain">2.0</span></code></pre></figure><h4>TestNG</h4> +<p>You can use <a href="http://testng.org";>TestNG</a> instead of JUnit. To select TestNG as the test framework, add this to your project:</p> +<figure class="highlight"><pre><code class="language-ruby" data-lang="ruby"><span class="nb">test</span><span class="o">.</span><span class="n">using</span> <span class="ss">:testng</span></code></pre></figure><p>Like all other options you can set with <code>test.using</code>, it affects the projects and all its sub-projects, so you only need to do this once at the top-most project to use TestNG throughout. You can also mix TestNG and JUnit by setting different projects to use different frameworks, but you can’t mix both frameworks in the same project. (And yes, <code>test.using :junit</code> will switch a project back to using JUnit)</p> +<p>TestNG works much like JUnit, it gets included in the dependency list along with JMock, Buildr picks test classes that contain methods annotated with <code>org.testng.annotations.Test</code>, and generates test reports in the <code>reports/testng</code> directory. At the moment we don’t have consolidated <span class="caps">HTML</span> reports for TestNG.</p> +<p>The TestNG test framework supports the following options:</p> +<table> + <tr> + <th>Option </th> + <th>Value </th> + </tr> + <tr> + <td> <code>:properties</code> </td> + <td> Hash of system properties available to the test case. </td> + </tr> + <tr> + <td> <code>:java_args</code> </td> + <td> Arguments passed as is to the <span class="caps">JVM</span>. </td> + </tr> +</table> +<p>You can use the <code>build.yaml</code> settings file to specify a particular version of TestNG, for example, to force your build to use TestNG 5.7:</p> +<figure class="highlight"><pre><code class="language-yaml" data-lang="yaml"><span class="l-Scalar-Plain">testng</span><span class="p-Indicator">:</span> <span class="l-Scalar-Plain">5.7</span></code></pre></figure><h4>JBehave</h4> +<p><a href="http://jbehave.org/";>JBehave</a> is a pure Java <span class="caps">BDD</span> framework, stories and behaviour specifications are written in the Java language.</p> +<p>To use JBehave in your project you can select it with <code>test.using :jbehave</code>.</p> +<p>This framework will search for the following patterns under your project:</p> +<figure class="highlight"><pre><code class="language-text" data-lang="text">src/spec/java/**/*Behaviour.java</code></pre></figure><p>Supports the following options:</p> +<table> + <tr> + <th>Option </th> + <th>Value </th> + </tr> + <tr> + <td> <code>:properties</code> </td> + <td> Hash of system properties available to the test case. </td> + </tr> + <tr> + <td> <code>:java_args</code> </td> + <td> Arguments passed as is to the <span class="caps">JVM</span>. </td> + </tr> +</table> +<p>You can use the <code>build.yaml</code> settings file to specify a particular version of JBehave, for example, to force your build to use JBehave 1.0.1:</p> +<figure class="highlight"><pre><code class="language-yaml" data-lang="yaml"><span class="l-Scalar-Plain">jbehave</span><span class="p-Indicator">:</span> <span class="l-Scalar-Plain">1.0.1</span></code></pre></figure><h3>Documentation</h3> +<p>Buildr offers support for using JavaDoc to generate documentation from any Java sources in a project.

By default, these sources are chosen only from the current project. However, it is possible to override this and generate documentation from the sources in a sub-project (potentially more than one):</p> +<figure class="highlight"><pre><code class="language-ruby" data-lang="ruby"><span class="n">define</span> <span class="s1">'foo'</span> <span class="k">do</span> + <span class="c1"># ...</span> + + <span class="n">doc</span><span class="o">.</span><span class="n">from</span> <span class="n">projects</span><span class="p">(</span><span class="s1">'foo:bar'</span><span class="p">,</span> <span class="s1">'foo'</span><span class="p">)</span> + + <span class="n">define</span> <span class="s1">'bar'</span> <span class="k">do</span> + <span class="c1"># ...</span> + <span class="k">end</span> +<span class="k">end</span></code></pre></figure><p>With this configuration, the <code>doc</code> task will use sources from both <code>foo:bar</code> and<br /> +<code>foo</code>.</p> +<p>The <code>doc</code> task supports any option that the <code>javadoc</code> command does (e.g. <code>-windowtitle</code>).

Of course you can configure a specific version of Scala for your project by adding the following entry in <code>build.yaml</code>:</p> +<figure class="highlight"><pre><code class="language-yaml" data-lang="yaml"><span class="l-Scalar-Plain">scala.version</span><span class="p-Indicator">:</span> <span class="l-Scalar-Plain">2.8.0.Beta1</span> <span class="c1"># Pick your version</span></code></pre></figure><p>Or, you can do the same programmatically:</p> +<figure class="highlight"><pre><code class="language-yaml" data-lang="yaml"><span class="c1"># Must be placed before require 'buildr/scala'</span> +<span class="l-Scalar-Plain">Buildr.settings.build['scala.version'] = "2.8.0.Beta1"</span></code></pre></figure><p>You may also determine the version in use by querying the <code>Scala.version</code> attribute:</p> +<figure class="highlight"><pre><code class="language-ruby" data-lang="ruby"><span class="no">Scala</span><span class="o">.</span><span class="n">version</span> <span class="c1"># => '2.8.0'</span></code></pre></figure><p>Regardless of how the Scala version is determined, if you have the same Scala version installed on your system and the SCALA_HOME environment variable points to it, then your local installation will be used. Otherwise, Buildr will download it from the <a href="http://oss.sonatype.org/content/repositories/releases";>Sonatype repository</a> which is automatically enlisted when you <code>require</code> Scala. The only drawback if you don’t have a local installation is the <span class="caps">FSC</span> compiler won’t be available.</p> +<p class="tip">For Mac users, if you have installed Scala via <a href="http://www.macports.org/";>MacPorts</a> Buildr will look in the<br /> +<code>/opt/local/share/scala/</code> directory if you have not set <code>SCALA_HOME</code>.</p> +<h3>Compiling Scala</h3> +<p>The Scala compiler looks for source files in the project’s <code>src/main/scala</code> directory, and defaults to compiling them into the <code>target/classes</code> directory. It looks for test cases in the project’s <code>src/test/scala</code> and defaults to compile them into the <code>target/test/classes</code> directory.</p> +<p>Any Java source files found in the <code>src/main/java</code> directory will be compiled using the Scala/Java joint compiler into the <code>target/classes</code> directory. Both the Java and the Scala sources are compiled with an inclusive classpath, meaning that you may have a Java class which depends upon a Scala class which depends upon a Java class, all within the same project. The Java sources will be compiled with the same dependencies as the Scala sources with the addition of the <code>scala-library.jar</code> file as required for Scala interop.</p> +<p>Note that you cannot use the Groovy <strong>and</strong> the Scala joint compilers in the same project. If both are required, the Groovy joint compiler will take precedence.</p> +<p>If you point the <code>compile</code> task at any other source directory, it will use the Scala compiler if any of these directories contains files with the extension <code>.scala</code>. The joint compilation of Java sources may only be pointed at an alternative directory using the feature to redefine the <code>_(:src, :main, :java)</code> path.</p> +<p>When using the Scala compiler, if you don’t specify the packaging type, it defaults to <span class="caps">JAR</span>.</p> +<p>The Scala compiler supports the following options:</p> +<table> + <tr> + <th>Option </th> + <th>Usage </th> + </tr> + <tr> + <td> <code>:debug</code> </td> + <td> If true, generates bytecode with debugging information. Scala 2.9 also accepts: none,source,line,vars,notc. </td> + </tr> + <tr> + <td> <code>:deprecation</code> </td> + <td> If true, shows deprecation messages. False by default. </td> + </tr> + <tr> + <td> <code>:make</code> </td> + <td> Make strategy to be used by the compiler (e.g. <code>:make=>'transitive'</code>). <strong>Scala 2.8 only</strong> </td> + </tr> + <tr> + <td> <code>:optimise</code> </td> + <td> Generates faster bytecode by applying optimisations to the program. </td> + </tr> + <tr> + <td> <code>:other</code> </td> + <td> Array of options passed to the compiler (e.g. <code>:other=>'-Xprint-types'</code>). </td> + </tr> + <tr> + <td> <code>:target</code> </td> + <td> Bytecode compatibility (e.g. ‘1.4’). </td> + </tr> + <tr> + <td> <code>:warnings</code> </td> + <td> Issue warnings when compiling. True when running in verbose mode. </td> + </tr> + <tr> + <td> <code>:javac</code> </td> + <td> A hash of options passed to the <code>javac</code> compiler verbatim. </td> + </tr> + <tr> + <td> <code>:incremental</code> </td> + <td> If true, enables incremental compilation using Zinc. </td> + </tr> +</table> +<h4>Fast Scala Compiler</h4> +<p>You may use <code>fsc</code>, the Fast Scala Compiler, which submits compilation jobs to a compilation daemon, by setting the environment variable <code>USE_FSC</code> to <code>yes</code>. Note that <code>fsc</code> <em>may</em> cache class libraries — don’t forget to run <code>fsc -reset</code> if you upgrade a library.</p> +<p>(Note <code>fsc</code> is not compatible with <code>zinc</code> incremental compilation.)</p> +<h4>Rebuild detection</h4> +<p><strong>Scala 2.7</strong></p> +<p>The Scala 2.7 compiler task assumes that each <code>.scala</code> source file generates a corresponding <code>.class</code> file under <code>target/classes</code> (or <code>target/test/classses</code> for tests). The source may generate more <code>.class</code> files if it contains more than one class, object, trait or for anonymous functions and closures.</p> +<p>For example, <code>src/main/scala/com/example/MyClass.scala</code> should generate at least <code>target/classes/com/example/MyClass.class</code>. If that it not the case, Buildr will always recompile your sources because it will assume this is a new source file that has never been compiled before.</p> +<p><strong>Scala 2.8</strong></p> +<p>Scala 2.8 provides a substantially better interface for implementing change detection. Whenever you use Scala 2.8 (see below), Buildr will auto-detect the version and enable this feature dynamically. After the <code>compile</code> task runs, the relevant target directory will contain a <code>.scala-deps</code> file, generated by the Scala compiler. The manner in which this file is used can be configured using the <code>:make</code> compiler option. The following values are available:</p> +<ul> + <li><code>:all</code> – Disables compiler-level change detection</li> + <li><code>:changed</code> – Only build changed files without considering file dependencies</li> + <li><code>:immediate</code> – <strong>unknown</strong></li> + <li><code>:transitive</code> – Build changed files as well as their transitive file dependencies</li> + <li><code>:transitivenocp</code> – Build changed files as well as their transitive file dependencies (<strong>default</strong>)</li> +</ul> +<p>Please note that there are limits to compiler-level change detection. Most notably, dependencies cannot be tracked across separate compilation targets. This would cause problems in the case where an <span class="caps">API</span> has been changed in a main source file. The test suite for the project will <strong>not</strong> be detected as requiring recompilation, potentially resulting in unexpected runtime exceptions. When in doubt, run <code>clean</code> to remove all dependency information. In extreme cases, it is possible to completely disable compiler-level change detection by adding the following statement to your project definition:</p> +<figure class="highlight"><pre><code class="language-ruby" data-lang="ruby"><span class="n">compile</span><span class="o">.</span><span class="n">using</span> <span class="ss">:make</span> <span class="o">=></span> <span class="ss">:all</span></code></pre></figure><p>Effectively, this is telling the Scala compiler to ignore the information it has built up regarding source file dependencies. When in this mode, only Buildr’s change detection semantics remain in play (as described above).</p> +<p>To avoid unusual behavior, compiler-level change detection is disabled whenever the joint Scala-Java compiler is used.

For example:</p> +<figure class="highlight"><pre><code class="language-yaml" data-lang="yaml"><span class="l-Scalar-Plain">jruby</span><span class="p-Indicator">:</span> <span class="l-Scalar-Plain">1.3.1</span></code></pre></figure><h4>RSpec</h4> +<p><a href="http://rspec.info/";>RSpec</a> is the de-facto <span class="caps">BDD</span> framework for ruby. It’s the framework used to test Buildr itself.</p> +<p>To use this framework in your project you can select it with <code>test.using :rspec</code>.</p> +<p>This framework will search for the following patterns under your project:</p> +<figure class="highlight"><pre><code class="language-text" data-lang="text">src/spec/ruby/**/*_spec.rb</code></pre></figure><p>Supports the following options:</p> +<table> + <tr> + <th>Option </th> + <th>Value </th> + </tr> + <tr> + <td> <code>:gems</code> </td> + <td> Hash of gems needed before running the tests. Keys are gem names, values are the required gem version. An example use of this option would be to require the ci_reporter gem to generate xml reports </td> + </tr> + <tr> + <td> <code>:requires</code> </td> + <td> Array of ruby files to require before running the specs </td> + </tr> + <tr> + <td> <code>:format</code> </td> + <td> Array of valid RSpec <code>--format</code> option values. Defaults to html report on the <code>reports</code> directory and text progress </td> + </tr> + <tr> + <td> <code>:output</code> </td> + <td> File path to output dump. <code>false</code> to supress output </td> + </tr> + <tr> + <td> <code>:fork</code> </td> + <td> Run the tests on a new java vm. (enabled unless running on JRuby) </td> + </tr> + <tr> + <td> <code>:properties</code> </td> + <td> Hash of system properties available to the test case. </td> + </tr> + <tr> + <td> <code>:java_args</code> </td> + <td> Arguments passed as is to the <span class="caps">JVM</span>.
