Class SoftAssertionsExtension

java.lang.Object

org.assertj.core.api.junit.jupiter.SoftAssertionsExtension

All Implemented Interfaces:

org.junit.jupiter.api.extension.AfterTestExecutionCallback, org.junit.jupiter.api.extension.Extension, org.junit.jupiter.api.extension.ParameterResolver

public class SoftAssertionsExtension
extends java.lang.Object
implements org.junit.jupiter.api.extension.ParameterResolver, org.junit.jupiter.api.extension.AfterTestExecutionCallback

Extension for JUnit Jupiter that provides support for injecting an instance of SoftAssertions or BDDSoftAssertions into test methods.

Applicability

In this context, the term "test method" refers to any method annotated with @Test, @RepeatedTest, @ParameterizedTest, @TestFactory, or @TestTemplate.
This extension does not inject SoftAssertions or BDDSoftAssertions arguments into test constructors or lifecycle methods.

Scope

The scope of the SoftAssertions or BDDSoftAssertions instance managed by this extension begins when a parameter of type SoftAssertions or BDDSoftAssertions is resolved for a test method.
The scope of the instance ends after the test method has been executed, this is when assertAll() will be invoked on the instance to verify that no soft assertions failed.

Example with SoftAssertions

  @ExtendWith(SoftAssertionsExtension.class)
 class ExampleTestCase {

     @Test
    void multipleFailures(SoftAssertions softly) {
       softly.assertThat(2 * 3).isEqualTo(0);
       softly.assertThat(Arrays.asList(1, 2)).containsOnly(1);
       softly.assertThat(1 + 1).isEqualTo(2);
    }
 }

Example with BDDSoftAssertions

  @ExtendWith(SoftAssertionsExtension.class)
 class ExampleTestCase {

     @Test
    void multipleFailures(BDDSoftAssertions softly) {
       softly.then(2 * 3).isEqualTo(0);
       softly.then(Arrays.asList(1, 2)).containsOnly(1);
       softly.then(1 + 1).isEqualTo(2);
    }
 }
