| <h2>Summary of Changes in version 4.6</h2> |
| |
| <h3>Max</h3> |
| |
| <p>JUnit now includes a new experimental Core, <code>MaxCore</code>. <code>MaxCore</code> |
| remembers the results of previous test runs in order to run new |
| tests out of order. <code>MaxCore</code> prefers new tests to old tests, fast |
| tests to slow tests, and recently failing tests to tests that last |
| failed long ago. There's currently not a standard UI for running |
| <code>MaxCore</code> included in JUnit, but there is a UI included in the JUnit |
| Max Eclipse plug-in at:</p> |
| |
| <p>http://www.junitmax.com/junitmax/subscribe.html</p> |
| |
| <p>Example:</p> |
| |
| <pre><code>public static class TwoUnEqualTests { |
| @Test |
| public void slow() throws InterruptedException { |
| Thread.sleep(100); |
| fail(); |
| } |
| |
| @Test |
| public void fast() { |
| fail(); |
| } |
| } |
| |
| @Test |
| public void rememberOldRuns() { |
| File maxFile = new File("history.max"); |
| MaxCore firstMax = MaxCore.storedLocally(maxFile); |
| firstMax.run(TwoUnEqualTests.class); |
| |
| MaxCore useHistory= MaxCore.storedLocally(maxFile); |
| List<Failure> failures= useHistory.run(TwoUnEqualTests.class) |
| .getFailures(); |
| assertEquals("fast", failures.get(0).getDescription().getMethodName()); |
| assertEquals("slow", failures.get(1).getDescription().getMethodName()); |
| } |
| </code></pre> |
| |
| <h3>Test scheduling strategies</h3> |
| |
| <p><code>JUnitCore</code> now includes an experimental method that allows you to |
| specify a model of the <code>Computer</code> that runs your tests. Currently, |
| the only built-in Computers are the default, serial runner, and two |
| runners provided in the <code>ParallelRunner</code> class: |
| <code>ParallelRunner.classes()</code>, which runs classes in parallel, and |
| <code>ParallelRunner.methods()</code>, which runs classes and methods in parallel.</p> |
| |
| <p>This feature is currently less stable than MaxCore, and may be |
| merged with MaxCore in some way in the future.</p> |
| |
| <p>Example:</p> |
| |
| <pre><code>public static class Example { |
| @Test public void one() throws InterruptedException { |
| Thread.sleep(1000); |
| } |
| @Test public void two() throws InterruptedException { |
| Thread.sleep(1000); |
| } |
| } |
| |
| @Test public void testsRunInParallel() { |
| long start= System.currentTimeMillis(); |
| Result result= JUnitCore.runClasses(ParallelComputer.methods(), |
| Example.class); |
| assertTrue(result.wasSuccessful()); |
| long end= System.currentTimeMillis(); |
| assertThat(end - start, betweenInclusive(1000, 1500)); |
| } |
| </code></pre> |
| |
| <h3>Comparing double arrays</h3> |
| |
| <p>Arrays of doubles can be compared, using a delta allowance for equality:</p> |
| |
| <pre><code>@Test |
| public void doubleArraysAreEqual() { |
| assertArrayEquals(new double[] {1.0, 2.0}, new double[] {1.0, 2.0}, 0.01); |
| } |
| </code></pre> |
| |
| <h3><code>Filter.matchDescription</code> API</h3> |
| |
| <p>Since 4.0, it has been possible to run a single method using the <code>Request.method</code> |
| API. In 4.6, the filter that implements this is exposed as <code>Filter.matchDescription</code>.</p> |
| |
| <h3>Documentation</h3> |
| |
| <ul> |
| <li><p>A couple classes and packages that once had empty javadoc have been |
| doc'ed.</p></li> |
| <li><p>Added how to run JUnit from the command line to the cookbook.</p></li> |
| <li><p>junit-4.x.zip now contains build.xml</p></li> |
| </ul> |
| |
| <h3>Bug fixes</h3> |
| |
| <ul> |
| <li>Fixed overly permissive @DataPoint processing (2191102)</li> |
| <li>Fixed bug in test counting after an ignored method (2106324)</li> |
| </ul> |
| |
| <h2>Summary of Changes in version 4.5</h2> |
| |
| <h3>Installation</h3> |
| |
| <ul> |
| <li>We are releasing <code>junit-4.6.jar</code>, which contains all the classes |
| necessary to run JUnit, and <code>junit-dep-4.6.jar</code>, which leaves out |
| hamcrest classes, for developers who already use hamcrest outside of |
| JUnit.</li> |
| </ul> |
| |
| <h3>Basic JUnit operation</h3> |
| |
| <ul> |
| <li><p>JUnitCore now more often exits with the correct exit code (0 for |
| success, 1 for failure)</p></li> |
| <li><p>Badly formed test classes (exceptions in constructors, classes |
| without tests, multiple constructors, Suite without @SuiteClasses) |
| produce more helpful error messages</p></li> |
| <li><p>Test classes whose only test methods are inherited from superclasses |
| now run.</p></li> |
| <li><p>Optimization to annotation processing can cut JUnit overhead by more than half |
| on large test classes, especially when using Theories. [Bug 1796847]</p></li> |
| <li><p>A failing assumption in a constructor ignores the class</p></li> |
| <li><p>Correct results when comparing the string "null" with potentially |
| null values. [Bug 1857283]</p></li> |
| <li><p>Annotating a class with <code>@RunWith(JUnit4.class)</code> will always invoke the |
| default JUnit 4 runner in the current version of JUnit. This default changed |
| from <code>JUnit4ClassRunner</code> in 4.4 to <code>BlockJUnit4ClassRunner</code> in 4.5 (see below), |
| and may change again.</p></li> |
| </ul> |
| |
| <h3>Extension</h3> |
| |
| <ul> |
| <li><p><code>BlockJUnit4Runner</code> is a new implementation of the standard JUnit 4 |
| test class functionality. In contrast to <code>JUnit4ClassRunner</code> (the old |
| implementation):</p> |
| |
| <ul> |
| <li><p><code>BlockJUnit4Runner</code> has a much simpler implementation based on |
| Statements, allowing new operations to be inserted into the |
| appropriate point in the execution flow.</p></li> |
| <li><p><code>BlockJUnit4Runner</code> is published, and extension and reuse are |
| encouraged, whereas <code>JUnit4ClassRunner</code> was in an internal package, |
| and is now deprecated.</p></li> |
| </ul></li> |
| <li><p><code>ParentRunner</code> is a base class for runners that iterate over |
| a list of "children", each an object representing a test or suite to run. |
| <code>ParentRunner</code> provides filtering, sorting, <code>@BeforeClass</code>, <code>@AfterClass</code>, |
| and method validation to subclasses.</p></li> |
| <li><p><code>TestClass</code> wraps a class to be run, providing efficient, repeated access |
| to all methods with a given annotation.</p></li> |
| <li><p>The new <code>RunnerBuilder</code> API allows extending the behavior of |
| Suite-like custom runners.</p></li> |
| <li><p><code>AssumptionViolatedException.toString()</code> is more informative</p></li> |
| </ul> |
| |
| <h3>Extra Runners</h3> |
| |
| <ul> |
| <li><p><code>Parameterized.eachOne()</code> has been removed</p></li> |
| <li><p>New runner <code>Enclosed</code> runs all static inner classes of an outer class.</p></li> |
| </ul> |
| |
| <h3>Theories</h3> |
| |
| <ul> |
| <li><p><code>@Before</code> and <code>@After</code> methods are run before and after each set of attempted parameters |
| on a Theory, and each set of parameters is run on a new instance of the test class.</p></li> |
| <li><p>Exposed API's <code>ParameterSignature.getType()</code> and <code>ParameterSignature.getAnnotations()</code></p></li> |
| <li><p>An array of data points can be introduced by a field or method |
| marked with the new annotation <code>@DataPoints</code></p></li> |
| <li><p>The Theories custom runner has been refactored to make it faster and |
| easier to extend</p></li> |
| </ul> |
| |
| <h3>Development</h3> |
| |
| <ul> |
| <li><p>Source has been split into directories <code>src/main/java</code> and |
| <code>src/test/java</code>, making it easier to exclude tests from builds, and |
| making JUnit more maven-friendly</p></li> |
| <li><p>Test classes in <code>org.junit.tests</code> have been organized into |
| subpackages, hopefully making finding tests easier.</p></li> |
| <li><p><code>ResultMatchers</code> has more informative descriptions.</p></li> |
| <li><p><code>TestSystem</code> allows testing return codes and other system-level interactions.</p></li> |
| </ul> |
| |
| <h2>Summary of Changes in version 4.4</h2> |
| |
| <p>JUnit is designed to efficiently capture developers' intentions about |
| their code, and quickly check their code matches those intentions. |
| Over the last year, we've been talking about what things developers |
| would like to say about their code that have been difficult in the |
| past, and how we can make them easier.</p> |
| |
| <h3>assertThat</h3> |
| |
| <p>Two years ago, Joe Walnes built a <a href="http://joe.truemesh.com/blog/000511.html">new assertion mechanism</a> on top of what was |
| then <a href="http://www.jmock.org/download.html">JMock 1</a>. The method name was <code>assertThat</code>, and the syntax looked like this:</p> |
| |
| <pre><code>assertThat(x, is(3)); |
| assertThat(x, is(not(4))); |
| assertThat(responseString, either(containsString("color")).or(containsString("colour"))); |
| assertThat(myList, hasItem("3")); |
| </code></pre> |
| |
| <p>More generally:</p> |
| |
| <pre><code>assertThat([value], [matcher statement]); |
| </code></pre> |
| |
| <p>Advantages of this assertion syntax include:</p> |
| |
| <ul> |
| <li><p>More readable and typeable: this syntax allows you to think in terms of subject, verb, object |
| (assert "x is 3") rathern than <code>assertEquals</code>, which uses verb, object, subject (assert "equals 3 x")</p></li> |
| <li><p>Combinations: any matcher statement <code>s</code> can be negated (<code>not(s)</code>), combined (<code>either(s).or(t)</code>), |
| mapped to a collection (<code>each(s)</code>), or used in custom combinations (<code>afterFiveSeconds(s)</code>)</p></li> |
| <li><p>Readable failure messages. Compare</p> |
| |
| <pre><code>assertTrue(responseString.contains("color") || responseString.contains("colour")); |
| // ==> failure message: |
| // java.lang.AssertionError: |
| |
| |
| assertThat(responseString, anyOf(containsString("color"), containsString("colour"))); |
| // ==> failure message: |
| // java.lang.AssertionError: |
| // Expected: (a string containing "color" or a string containing "colour") |
| // got: "Please choose a font" |
| </code></pre></li> |
| <li><p>Custom Matchers. By implementing the <code>Matcher</code> interface yourself, you can get all of the |
| above benefits for your own custom assertions.</p></li> |
| <li><p>For a more thorough description of these points, see <a href="http://joe.truemesh.com/blog/000511.html">Joe Walnes's |
| original post</a>.:</p></li> |
| </ul> |
| |
| <p>We have decided to include this API directly in JUnit. |
| It's an extensible and readable syntax, and because it enables |
| new features, like <a href="#assumptions">assumptions</a> and <a href="#theories">theories</a>.</p> |
| |
| <p>Some notes:</p> |
| |
| <ul> |
| <li>The old assert methods are never, ever, going away. <br /> |
| Developers may continue using the old <code>assertEquals</code>, <code>assertTrue</code>, and |
| so on.</li> |
| <li><p>The second parameter of an <code>assertThat</code> statement is a <code>Matcher</code>. |
| We include the Matchers we want as static imports, like this:</p> |
| |
| <pre><code>import static org.hamcrest.CoreMatchers.is; |
| </code></pre> |
| |
| <p>or:</p> |
| |
| <pre><code>import static org.hamcrest.CoreMatchers.*; |
| </code></pre></li> |
| <li><p>Manually importing <code>Matcher</code> methods can be frustrating. [Eclipse |
| 3.3][] includes the ability to |
| define |
| "Favorite" classes to import static methods from, which makes it easier |
| (Search for "Favorites" in the Preferences dialog). |
| We expect that support for static imports will improve in all Java IDEs in the future.</p></li> |
| <li><p>To allow compatibility with a wide variety of possible matchers, |
| we have decided to include the classes from hamcrest-core, |
| from the <a href="http://code.google.com/p/hamcrest/">Hamcrest</a> project. This is the first time that |
| third-party classes have been included in JUnit. </p></li> |
| <li><p>To allow developers to maintain full control of the classpath contents, the JUnit distribution also provides an unbundled junit-dep jar, |
| ie without hamcrest-core classes included. This is intended for situations when using other libraries that also depend on hamcrest-core, to |
| avoid classloading conflicts or issues. Developers using junit-dep should ensure a compatible version of hamcrest-core jar (ie 1.1+) is present in the classpath.</p></li> |
| <li><p>JUnit currently ships with a few matchers, defined in |
| <code>org.hamcrest.CoreMatchers</code> and <code>org.junit.matchers.JUnitMatchers</code>. <br /> |
| To use many, many more, consider downloading the <a href="http://hamcrest.googlecode.com/files/hamcrest-all-1.1.jar">full hamcrest package</a>.</p></li> |
| <li><p>JUnit contains special support for comparing string and array |
| values, giving specific information on how they differ. This is not |
| yet available using the <code>assertThat</code> syntax, but we hope to bring |
| the two assert methods into closer alignment in future releases.</p></li> |
| </ul> |
| |
| <h3>assumeThat</h3> |
| |
| <p><a name="assumptions" /> |
| Ideally, the developer writing a test has control of all of the forces that might cause a test to fail. |
| If this isn't immediately possible, making dependencies explicit can often improve a design. <br /> |
| For example, if a test fails when run in a different locale than the developer intended, |
| it can be fixed by explicitly passing a locale to the domain code.</p> |
| |
| <p>However, sometimes this is not desirable or possible. <br /> |
| It's good to be able to run a test against the code as it is currently written, |
| implicit assumptions and all, or to write a test that exposes a known bug. |
| For these situations, JUnit now includes the ability to express "assumptions":</p> |
| |
| <pre><code>import static org.junit.Assume.* |
| |
| @Test public void filenameIncludesUsername() { |
| assumeThat(File.separatorChar, is('/')); |
| assertThat(new User("optimus").configFileName(), is("configfiles/optimus.cfg")); |
| } |
| |
| @Test public void correctBehaviorWhenFilenameIsNull() { |
| assumeTrue(bugFixed("13356")); // bugFixed is not included in JUnit |
| assertThat(parse(null), is(new NullDocument())); |
| } |
| </code></pre> |
| |
| <p>With this beta release, a failed assumption will lead to the test being marked as passing, |
| regardless of what the code below the assumption may assert. |
| In the future, this may change, and a failed assumption may lead to the test being ignored: |
| however, third-party runners do not currently allow this option.</p> |
| |
| <p>We have included <code>assumeTrue</code> for convenience, but thanks to the |
| inclusion of Hamcrest, we do not need to create <code>assumeEquals</code>, |
| <code>assumeSame</code>, and other analogues to the <code>assert*</code> methods. All of |
| those functionalities are subsumed in assumeThat, with the appropriate |
| matcher.</p> |
| |
| <p>A failing assumption in a <code>@Before</code> or <code>@BeforeClass</code> method will have the same effect |
| as a failing assumption in each <code>@Test</code> method of the class.</p> |
| |
| <h3>Theories</h3> |
| |
| <p><a name="theories" /> |
| More flexible and expressive assertions, combined with the ability to |
| state assumptions clearly, lead to a new kind of statement of intent, |
| which we call a "Theory". A test captures the intended behavior in |
| one particular scenario. A theory allows a developer to be |
| as precise as desired about the behavior of the code in possibly |
| infinite numbers of possible scenarios. For example:</p> |
| |
| <pre><code>@RunWith(Theories.class) |
| public class UserTest { |
| @DataPoint public static String GOOD_USERNAME = "optimus"; |
| @DataPoint public static String USERNAME_WITH_SLASH = "optimus/prime"; |
| |
| @Theory public void filenameIncludesUsername(String username) { |
| assumeThat(username, not(containsString("/"))); |
| assertThat(new User(username).configFileName(), containsString(username)); |
| } |
| } |
| </code></pre> |
| |
| <p>This makes it clear that the user's filename should be included in the |
| config file name, only if it doesn't contain a slash. Another test |
| or theory might define what happens when a username does contain a slash.</p> |
| |
| <p><code>UserTest</code> will attempt to run <code>filenameIncludesUsername</code> on |
| every compatible <code>DataPoint</code> defined in the class. If any of the |
| assumptions fail, the data point is silently ignored. If all of the |
| assumptions pass, but an assertion fails, the test fails.</p> |
| |
| <p>The support for Theories has been absorbed from the <a href="http://popper.tigris.org">Popper</a> |
| project, and <a href="http://popper.tigris.org/tutorial.html">more complete documentation</a> can be found |
| there.</p> |
| |
| <p>Defining general statements in this way can jog the developer's memory |
| about other potential data points and tests, also allows <a href="http://www.junitfactory.org">automated |
| tools</a> to <a href="http://shareandenjoy.saff.net/2007/04/popper-and-junitfactory.html">search</a> for new, unexpected data |
| points that expose bugs.</p> |
| |
| <h3>Other changes</h3> |
| |
| <p>This release contains other bug fixes and new features. Among them:</p> |
| |
| <ul> |
| <li><p>Annotated descriptions</p> |
| |
| <p>Runner UIs, Filters, and Sorters operate on Descriptions of test |
| methods and test classes. These Descriptions now include the |
| annotations on the original Java source element, allowing for richer |
| display of test results, and easier development of annotation-based |
| filters.</p></li> |
| <li><p>Bug fix (1715326): assertEquals now compares all Numbers using their |
| native implementation of <code>equals</code>. This assertion, which passed in |
| 4.3, will now fail:</p> |
| |
| <p>assertEquals(new Integer(1), new Long(1));</p> |
| |
| <p>Non-integer Numbers (Floats, Doubles, BigDecimals, etc), |
| which were compared incorrectly in 4.3, are now fixed.</p></li> |
| <li><p><code>assertEquals(long, long)</code> and <code>assertEquals(double, double)</code> have |
| been re-introduced to the <code>Assert</code> class, to take advantage of |
| Java's native widening conversions. Therefore, this still passes:</p> |
| |
| <p>assertEquals(1, 1L);</p></li> |
| <li><p>The default runner for JUnit 4 test classes has been refactored. |
| The old version was named <code>TestClassRunner</code>, and the new is named |
| <code>JUnit4ClassRunner</code>. Likewise, <code>OldTestClassRunner</code> is now |
| <code>JUnit3ClassRunner</code>. The new design allows variations in running |
| individual test classes to be expressed with fewer custom classes. |
| For a good example, see the source to |
| <code>org.junit.experimental.theories.Theories</code>.</p></li> |
| <li><p>The rules for determining which runner is applied by default to a |
| test class have been simplified:</p> |
| |
| <ol> |
| <li><p>If the class has a <code>@RunWith</code> annotation, the annotated runner |
| class is used.</p></li> |
| <li><p>If the class can be run with the JUnit 3 test runner (it |
| subclasses <code>TestCase</code>, or contains a <code>public static Test suite()</code> |
| method), JUnit38ClassRunner is used.</p></li> |
| <li><p>Otherwise, JUnit4ClassRunner is used.</p></li> |
| </ol> |
| |
| <p>This default guess can always be overridden by an explicit |
| <code>@RunWith(JUnit4ClassRunner.class)</code> or |
| <code>@RunWith(JUnit38ClassRunner.class)</code> annotation.</p> |
| |
| <p>The old class names <code>TestClassRunner</code> and <code>OldTestClassRunner</code> |
| remain as deprecated.</p></li> |
| <li><p>Bug fix (1739095): Filters and Sorters work correctly on test |
| classes that contain a <code>suite</code> method like:</p> |
| |
| <p>public static junit.framework.Test suite() { |
| return new JUnit4TestAdapter(MyTest.class); |
| }</p></li> |
| <li><p>Bug fix (1745048): @After methods are now correctly called |
| after a test method times out.</p></li> |
| </ul> |
| |
| <h2> |
| <a NAME="Summary of"></a>Summary of Changes in version 4.3.1</h2> |
| <p> |
| <ul> |
| <li>Bug fix: 4.3 introduced a |
| <a href="https://sourceforge.net/tracker/?func=detail&atid=115278&aid=1684562&group_id=15278">bug</a> |
| that caused a NullPointerException |
| when comparing a null reference to a non-null reference in <tt>assertEquals</tt>. |
| This has been fixed. |
| <li>Bug fix: The binary jar for 4.3 <a href="https://sourceforge.net/tracker/?func=detail&atid=115278&aid=1686931&group_id=15278">accidentally</a> included the tests and sample code, |
| which are now removed for a smaller download, but, as always, available from the |
| full zip. |
| </ul> |
| </p> |
| |
| <h2> |
| <a NAME="Summary of"></a>Summary of Changes with version 4.3</h2> |
| <p> |
| <ul> |
| <li>Changes in array equality. Using <tt>assertEquals</tt> to compare array contents is now deprecated. |
| In the future, <tt>assertEquals</tt> will revert to its pre-4.0 meaning of comparing objects based on |
| Java's <tt>Object.equals</tt> semantics. To compare array contents, use the new, more reliable |
| <tt>Assert.assertArrayEquals</tt> methods. |
| <li>The <tt>@Ignore</tt> annotation can now be applied to classes, to ignore the entire class, instead of |
| individual methods. |
| <li>Originally, developers who wanted to use a static <tt>suite()</tt> method from JUnit 3.x with a JUnit 4.x |
| runner had to annotate the class with <tt>@RunWith(AllTests.class)</tt>. In the common case, this requirement |
| has been removed. However, when such a class is wrapped with a JUnit4TestAdapter (which we believe is rare), the |
| results may not be as expected. |
| <li>Improved error messages for array comparison("arrays first differed at element [1][0]") |
| <li>Bug fix: Inaccessible base class is caught at test construction time. |
| <li>Bug fix: Circular suites are caught at test construction time. |
| <li>Bug fix: Test constructors that throw exceptions are reported correctly. |
| <li><b>For committers and extenders</b> |
| <ul> |
| <li>Sources now are in a separate "src" directory (this means a big break in the CVS history) |
| <li>Improved documentation in <tt>Request</tt>, <tt>RunWith</tt> |
| </ul> |

| tagging test classes by subclassing junit.framework.TestCase and tagging test methods by |
| starting their name with "test", you now tag test methods with the @Test annotation. |

| <a NAME="Installation"></a>Installation</h2> |
| Below are the installation steps for installing JUnit: |
| <ol> |
| <li> |
| unzip the junit4.6.zip file</li> |
| |
| <li> |
| add<i> </i><b>junit-4.6.jar</b> to the CLASSPATH. For example: |
| <tt> set classpath=%classpath%;INSTALL_DIR\junit-4.6.jar;INSTALL_DIR</tt></li> |
| |
| <li> |
| test the installation by running <tt>java org.junit.runner.JUnitCore org.junit.tests.AllTests</tt></li> |
| |
| <br><b><font color="#FF0000">Notice</font></b>: that the tests are not |
| contained in the junit-4.6.jar but in the installation directory directly. |
| Therefore make sure that the installation directory is on the class path |
| </ol> |
| <b><font color="#FF0000">Important</font></b>: don't install junit-4.6.jar |
| into the extension directory of your JDK installation. If you do so the |
| test class on the files system will not be found. |
| <h2> |
| <a NAME="Getting"></a>Getting Started</h2> |
| To get started with unit testing and JUnit read the article: |
| <a href="doc/cookbook/cookbook.htm">JUnit Cookbook</a>. |
| <br>This article describes basic test writing using JUnit 4. |
| <p>You find additional samples in the org.junit.samples package: |
| <ul> |
