| <li> |
| <p>Add JUnit 5 library to the build path:</p> |

| <li> |
| <p>New JUnit Test Case wizard offers to add it while creating a new JUnit Jupiter test:</p> |
| <p><img src="images/add-junit-5-lib.png" alt=""/></p> |
| </li> |
| <li> |
| <p>Quick Fix <b>(Ctrl+1)</b> proposal on <b><code>@Test</code></b>, <b><code>@TestFactory</code></b>, <b><code>@ParameterizedTest</code></b> and <b><code>@RepeatedTest</code></b> annotations:</p> |

| <p>Create a JUnit Jupiter test method with the new <b>test_jupiter</b> template:</p> |
| <p><img src="images/junit-jupiter-test-method-template.png" alt=""/></p> |

| </li> |
| |
| <li> |
| <p>JUnit Jupiter’s <code>Assertions</code>, <code>Assumptions</code>, <code>DynamicContainer</code> and <code>DynamicTest</code> classes are now added to <b>Eclipse Favorites</b> by default:</p> |
| <p><img src="images/content-assist-favorites.png" alt=""/></p> |
| <p>This allows you to quickly import the static methods from these classes in your code via Content Assist <b>(Ctrl + Space)</b> and Quick Fix <b>(Ctrl + 1)</b>.</p> |
| </li> |
| |
| <li> |
| <p>View all the failures from grouped assertions in the same <b>Result Comparison</b> dialog opened from JUnit view:</p> |
| <p><img src="images/grouped-assertions-result-comparison.png" alt=""/></p> |
| </li> |
| |
| <li> |
| <p>View the number of disabled tests and tests with assumption failures on hover in JUnit view:</p> |
| <p><img src="images/skipped-tests.png" alt=""/></p> |
| </li> |
| |
| <li> |
| <p>Use <b>Go to File</b> action or just double-click to navigate to the test from JUnit view even when the test is displayed with a custom name:</p> |
| <p><img src="images/display-name.png" alt=""/></p> |
| </li> |
| |
| <li> |
| <p>(Re-)Run a single <b><code>@Nested</code></b> test class by using the <b>Run</b> action in JUnit view or Outline view. |
| You can even right-click on a nested test class name in the editor and use the <b>Run As</b> action: |
| </p> |
| <p><img src="images/run-nested-class.png" alt=""/></p> |
| </li> |
| |
| <li> |
| <p>The <b>Test Method Selection</b> dialog in JUnit launch configuration now shows the method parameter types also:</p> |
| <p><img src="images/test-method-selection-dialog.png" alt=""/></p> |
| </li> |
| |
| <li> |
| <p>Note: This functionality has been replaced with the new <a href="https://www.eclipse.org/eclipse/news/4.8/M3/#junit5-tags">Configure Tags</a> dialog in M3.</p> |
| <p>You can provide tags to be included in or excluded from a test run via <b>Program arguments</b> in the Arguments tab of JUnit launch configuration. The options are: </p> |
| <ul> |
| <li>--include-tag <String></li> |
| <li>--exclude-tag <String></li> |
| </ul> |
| <p>where <String> is a tag to be included in or excluded from the test run. These options can be repeated with newline separation:</p> |
| <p><img src="images/junit-tags.png" alt=""/></p> |
| </li> |
| </ul> |
| |
| <p><b>Note:</b></p> |
| <ul> |
| <li> |
| If you are using an Eclipse workspace where you were running your JUnit 5 tests via <code>@RunWith(JUnitPlatform.class)</code> in Eclipse without JUnit 5 support |
| then you will have JUnit 4 as the test runner in their launch configurations. Before executing these tests in Eclipse with JUnit 5 support, you should either |
| change their test runner to JUnit 5 or delete them so that new launch configurations are created with JUnit 5 test runner while running the tests: |
| <p><img src="images/test-runner-update.png" alt=""/></p> |
| </li> |
| <li> |
| We do not support running tests in a setup where an old Eclipse build (not having JUnit 5 support) is using a new Eclipse build (having JUnit 5 support) as target. Also, developers who have |
| the JDT JUnit runtime bundles <code>(org.eclipse.jdt.junit.runtime, org.eclipse.jdt.junit4.runtime)</code> checked out and pull the latest changes will run into the above issue. |
| You are expected to use a new Eclipse build for the development. |
