The JUnit Platform serves as a foundation for launching testingframeworks on the JVM. It also defines the TestEngine API for developing a testingframework that runs on the platform. Furthermore, the platform provides aConsole Launcher to launch the platform from thecommand line and the JUnit Platform Suite Engine for running a custom test suite usingone or more test engines on the platform. First-class support for the JUnit Platform alsoexists in popular IDEs (see IntelliJ IDEA,Eclipse, NetBeans, andVisual Studio Code) and build tools (see Gradle,Maven, and Ant).
JUnit Jupiter is the combination of the programming model andextension model for writing tests and extensions in JUnit 5. The Jupitersub-project provides a TestEngine for running Jupiter based tests on the platform.

Test methods and lifecycle methods may be declared locally within the current test class,inherited from superclasses, or inherited from interfaces (seeTest Interfaces and Default Methods). In addition, test methods andlifecycle methods must not be abstract and must not return a value (except @TestFactorymethods which are required to return a value).
Test methods and lifecycle methods are inherited unless they are overridden according tothe visibility rules of the Java language. For example, a @Test method from a superclasswill always be applied in a subclass unless the subclass explicitly overrides the method.Similarly, if a package-private @Test method is declared in a superclass that resides ina different package than the subclass, that @Test method will always be applied in thesubclass since the subclass cannot override a package-private method from a superclass ina different package.
The following test class demonstrates the use of @Test methods and all supportedlifecycle methods. For further information on runtime semantics, seeTest Execution Order andWrapping Behavior of Callbacks.
JUnit Jupiter supports custom display name generators that can be configured via the@DisplayNameGeneration annotation. Values provided via @DisplayName annotationsalways take precedence over display names generated by a DisplayNameGenerator.
You can use the junit.jupiter.displayname.generator.defaultconfiguration parameter to specify the fully qualifiedclass name of the DisplayNameGenerator you would like to use by default. Just like fordisplay name generators configured via the @DisplayNameGeneration annotation, thesupplied class has to implement the DisplayNameGenerator interface. The default displayname generator will be used for all tests unless the @DisplayNameGeneration annotationis present on an enclosing test class or test interface. Values provided via@DisplayName annotations always take precedence over display names generated by aDisplayNameGenerator.
For example, to use the ReplaceUnderscores display name generator by default, you shouldset the configuration parameter to the corresponding fully qualified class name (e.g., insrc/test/resources/junit-platform.properties):
JUnit Jupiter comes with many of the assertion methods that JUnit 4 has and adds a fewthat lend themselves well to being used with Java 8 lambdas. All JUnit Jupiter assertionsare static methods in the org.junit.jupiter.api.Assertions class.
The various assertTimeoutPreemptively() methods in the Assertions class executethe provided executable or supplier in a different thread than that of the callingcode. This behavior can lead to undesirable side effects if the code that is executedwithin the executable or supplier relies on java.lang.ThreadLocal storage.
JUnit Jupiter also comes with a few assertion methods that lend themselves well to beingused in Kotlin. All JUnit Jupiter Kotlin assertions are top-levelfunctions in the org.junit.jupiter.api package.
Even though the assertion facilities provided by JUnit Jupiter are sufficient for manytesting scenarios, there are times when more power and additional functionality such asmatchers are desired or required. In such cases, the JUnit team recommends the use ofthird-party assertion libraries such as AssertJ, Hamcrest, Truth, etc. Developersare therefore free to use the assertion library of their choice.
The following example demonstrates how to use the assertThat() support from Hamcrest ina JUnit Jupiter test. As long as the Hamcrest library has been added to the classpath,you can statically import methods such as assertThat(), is(), and equalTo() andthen use them in tests like in the assertWithHamcrestMatcher() method below.
JUnit Jupiter provides robust support for handling test exceptions. This includes thebuilt-in mechanisms for managing test failures due to exceptions, the role of exceptionsin implementing assertions and assumptions, and how to specifically assert non-throwingconditions in code.
In JUnit Jupiter, if an exception is thrown from a test method, a lifecycle method, or anextension and not caught within that test method, lifecycle method, or extension, theframework will mark the test or test class as failed.
JUnit Jupiter offers specialized assertions for testing that specific exceptions arethrown under expected conditions. The assertThrows() and assertThrowsExactly()assertions are critical tools for validating that your code responds correctly to errorconditions by throwing the appropriate exceptions.
The assertThrows() method is used to verify that a particular type of exception isthrown during the execution of a provided executable block. It not only checks for thetype of the thrown exception but also its subclasses, making it suitable for moregeneralized exception handling tests. The assertThrows() assertion method returns thethrown exception object to allow performing additional assertions on it.
The assertThrowsExactly() method is used when you need to assert that the exceptionthrown is exactly of a specific type, not allowing for subclasses of the expectedexception type. This is useful when precise exception handling behavior needs to bevalidated. Similar to assertThrows(), the assertThrowsExactly() assertion method alsoreturns the thrown exception object to allow performing additional assertions on it.
Although any exception thrown from a test method will cause the test to fail, there arecertain use cases where it can be beneficial to explicitly assert that an exception isnot thrown for a given code block within a test method. The assertDoesNotThrow()assertion can be used when you want to verify that a particular piece of code does notthrow any exceptions.
If a test method is disabled via @Disabled, that prevents execution of the test methodand method-level lifecycle callbacks such as @BeforeEach methods, @AfterEach methods,and corresponding extension APIs. However, that does not prevent the test class from beinginstantiated, and it does not prevent the execution of class-level lifecycle callbackssuch as @BeforeAll methods, @AfterAll methods, and corresponding extension APIs.
The ExecutionCondition extension API in JUnit Jupiter allowsdevelopers to either enable or disable a test class or test method based on certainconditions programmatically. The simplest example of such a condition is the built-inDisabledCondition which supports the @Disabled annotation (seeDisabling Tests).
In addition to @Disabled, JUnit Jupiter also supports several other annotation-basedconditions in the org.junit.jupiter.api.condition package that allow developers toenable or disable test classes and test methods declaratively. If you wish to providedetails about why they might be disabled, every annotation associated with these built-inconditions has a disabledReason attribute available for that purpose.
When multiple ExecutionCondition extensions are registered, a test class or test methodis disabled as soon as one of the conditions returns disabled. If a test class isdisabled, all test methods within that class are automatically disabled as well. If a testmethod is disabled, that prevents execution of the test method and method-level lifecyclecallbacks such as @BeforeEach methods, @AfterEach methods, and corresponding extensionAPIs. However, that does not prevent the test class from being instantiated, and it doesnot prevent the execution of class-level lifecycle callbacks such as @BeforeAll methods,@AfterAll methods, and corresponding extension APIs.
Note that any of the conditional annotations listed in the following sections may alsobe used as a meta-annotation in order to create a custom composed annotation. Forexample, the @TestOnMac annotation in the@EnabledOnOs demo shows how you cancombine @Test and @EnabledOnOs in a single, reusable annotation.
Unless otherwise stated, each of the conditional annotations listed in the followingsections can only be declared once on a given test interface, test class, or test method.If a conditional annotation is directly present, indirectly present, or meta-presentmultiple times on a given element, only the first such annotation discovered by JUnit willbe used; any additional declarations will be silently ignored. Note, however, that eachconditional annotation may be used in conjunction with other conditional annotations inthe org.junit.jupiter.api.condition package.
A container or test may be enabled or disabled on particular versions of the JavaRuntime Environment (JRE) via the @EnabledOnJre and @DisabledOnJre annotationsor on a particular range of versions of the JRE via the @EnabledForJreRange and@DisabledForJreRange annotations. The range defaults to JRE.JAVA_8 as the lowerborder (min) and JRE.OTHER as the higher border (max), which allows usage ofhalf open ranges.
A container or test may be enabled or disabled within aGraalVM native image via the@EnabledInNativeImage and @DisabledInNativeImage annotations. These annotations aretypically used when running tests within a native image using the Gradle and Mavenplug-ins from the GraalVM NativeBuild Tools project.
