Package org.assertj.core.api.junit.jupiter

Class SoftlyExtension

  • All Implemented Interfaces:
    org.junit.jupiter.api.extension.AfterTestExecutionCallback, org.junit.jupiter.api.extension.Extension, org.junit.jupiter.api.extension.TestInstancePostProcessor
    @Deprecated
public class SoftlyExtension
extends Object
implements org.junit.jupiter.api.extension.AfterTestExecutionCallback, org.junit.jupiter.api.extension.TestInstancePostProcessor
    Deprecated.
    This functionality (and more) has been rolled into SoftAssertionsExtension as of AssertJ 3.18.0.
    Extension for JUnit Jupiter that provides support for injecting an instance of SoftAssertions into a class test SoftAssertions field.

    The injection occurs before each test method execution, after each test assertAll() is invoked to evaluate all test assertions.

    A nested test class can provide a SoftAssertions field when it extends this extension or can inherit the parent's Soft assertions field

    This extension throws an IllegalStateException if:

    • the test class lifecycle is TestInstance.Lifecycle.PER_CLASS (see explanation below).
    • multiple SoftAssertions fields are found
    • no SoftAssertions field is found

    Detecting multiple SoftAssertions fields is a best effort at the time of this writing, some cases are not detected.

    Limitations:

    1. Cannot be used with test context that have PER_CLASS life cycle as the same SoftAssertions would be reused between tests.
    2. May exhibit unpredictable behaviour in concurrent test execution

    If you hit such limitations, consider using SoftAssertionsExtension instead, since 3.18.0, SoftAssertionsExtension supports field injection with neither of these two limitations.

    Example: 

     @ExtendWith(SoftlyExtension.class)
 public class SoftlyExtensionExample {

   // initialized by the SoftlyExtension extension
   private SoftAssertions soft;

   @Test
   public void chained_soft_assertions_example() {
     String name = "Michael Jordan - Bulls";
     soft.assertThat(name)
         .startsWith("Mi")
         .contains("Bulls");
     // no need to call softly.assertAll(), this is done by the extension
   }

   // nested classes test work too
   @Nested
   class NestedExample {

     @Test
     public void football_assertions_example() {
       String kylian = "Kylian Mbappé";
       soft.assertThat(kylian)
           .startsWith("Ky")
           .contains("bap");
       // no need to call softly.assertAll(), this is done by the extension
     }
   }
 }
