JUnit 5 is a very popular unit testing framework mainly used for -based applications. JUnit 5 consists of 3 different modules that are JUnit Platform, JUnit Jupiter, and JUnit Vintage.
So JUnit = JUnit Platform + JUnit Jupiter + JUnit Vintage.
@BeforeEach | This will run before every test method. |
@AfterEach | This will run after every test method. |
@BeforeAll | This will run before all the test methods. |
@AfterAll | This will run after all the test methods. |
@Test | To declare a method as junit test. |
@DisplayName | To give a user-defined name to a method. |
@Disable | This is used to ignore a particular test method/class. |
@Nested | To create nested test classes. |
@Tag | For marking a test method. |
@TestFactory | For dynamic testing. |
Assertions are a collection of utility methods that support asserting conditions in tests.
assertAll (Executable.. executables) | Shows that all supplied executables do not throw exceptions. |
assertAll (Stream executables) | Shows that all supplied executables do not throw exceptions. |
assertAll (Stringheading,Executableā¦ executables) | Shows that all supplied executables do not throw exceptions. |
assertAll (Stringheading , Stream executables) | Shows that all supplied executables do not throw exceptions. |
assertArrayEquals (boolean[] expected,Boolean[] actual ) | Asserts that the expected and actual boolean arrays are equal. |
assertArrayEquals (boolean[] expected ,Boolean[] actual, String msg) | Asserts that expected and actual boolean arrays are equal. |

assertNotEquals ( object unexpected, Object actual, Supplier < String > msgSupplier) | Asserts that expected and actual are not equal. |
assertNotEquals ( object unexpected, Object actual, String msg) | Asserts that expected and actual are not equal. |
assertNotNull ( Object actual) | Asserts that actual is not null. |
assertNotNull ( Obj actual, String msg) | Asserts that the actual is not null. |
assertNotNull ( Object actual, Supplier < String > msgSupplier) | Asserts that the actual is not null. |
assertNotSame ( Object unexpected, Object actual, String msg) | Asserts that expected and actual do not refer to the same object. |
assertNotSame ( Object unexpected, Object actual, Supplier < String > msgSupplier) | Asserts that expected and actual do not refer to the same object. |
assertNull ( Obj actual) | Shows that actual is null. |
assertNull ( Obj actual, String msg) | Shows that actual is null. |
assertNull ( Obj actual, Supplier < String > msgSupplier) | Shows that actual is null. |
assertSame ( Obj expected,Obj actual) | Shows that expected and actual refer to the same object. |
assertSame ( Obj expected, Obj actual, String msg) | Shows that expected and actual refer to the same object. |
assertSame (Obj expected,Obj actual, Supplier < String > msgSupplier) | Shows that expected and actual refer to the same object. |
assertThrows ( Class expectedType, Executable executable) | To know that execution of the supplied executable throws an exception of the expectedType and returns the exception. |
assertThrows ( Class expectedType, Executable executable, String message) | To know that execution of the supplied executable throws an exception of the expectedType and returns the exception. |
assertThrows ( Class expectedType, Executable executable, Supplier < String > msgSupplier) | To know that execution of the supplied executable throws an exception of the expectedType and returns the exception. |
assertTimeout ( Duration timeout, ThrowingSupplier supplier, String msg) | To know that execution of the supplied supplier completes before the given timeout is exceeded. |
assertTimeout ( Duration timeout, ThrowingSupplier supplier) | To know that execution of the supplied supplier completes before the given timeout is exceeded. |
assertTimeout ( Duration timeout, Executable executable, Supplier < String > msgSupplier) | To know that execution of the supplied supplier completes before the given timeout is exceeded. |
assertTrue ( BooleanSupplier booleanSupplier, Supplier< String > msgSupplier) | To know that the boolean condition supplied by booleanSupplier is true. |
assertTrue ( BooleanSupplier booleanSupplier, String msg) | To know that the boolean condition supplied by booleanSupplier is true. |
assertTrue (boolean condition, Supplier < String > msgSupplier) | To know that the supplied condition is true. |
assertTrue ( BooleanSupplier booleanSupplier) | To know that the boolean condition supplied by booleanSupplier is true. |
fail ( String msg) | Fails a test with the failure message retrieved from the given msgSupplier. |
fail ( String msg, Throwable cause) | Fails a test with the given failure message as well as the underlying cause. |
fail ( Supplier < string > msgSupplier) | Fails a test with the failure message retrieved from the given msgSupplier. |
fail ( Throwable cause) | Fails a test with the given underlying cause. |
It is very much important for a full stack developer to test his/her code. So JUnit 5 is the perfect tool for managing, and proper executing of the test cases. It also helps to reduce the time for debugging.
