JUnit5是否有类似的错误收集器规则

Question

JUnit4中有ErrorCollector规则，现在我们必须在迁移到JUnit5期间切换到扩展。这里描述了ErrorCollector的用法https://junit.org/junit4/javadoc/4.12/org/junit/rules/ErrorCollector.htmlJUnit5中是否有类似的扩展。我在assert-j中找到了一个https://www.javadoc.io/doc/org.assertj/assertj-core/latest/org/assertj/core/api/junit/jupiter/SoftAssertionsExtension.html但JUnit 5中仍然支持相同的东西作为扩展吗？

注意：我想在系统测试级别上使用它。所以我要做第一步-

assertAll(() -> {{Some block of code getting variable2}
                    assertEquals({what we expect from variable1}, variable1, "variable1 is wrong")},
                {Some block of code getting variable2}
        assertEquals({what we expect from variable2}, variable2, "variable2 is wrong"),
                {Some block of code getting variable3}
        assertEquals({what we expect from variable3}, variable3, "variable3 is wrong"));

这种方法看起来并不清晰，而且看起来比这里描述的更糟糕https://assertj.github.io/doc/#assertj-core-junit5-soft-assertions

目前，我认为最好的方法是像这样使用assert-j

@ExtendWith(SoftAssertionsExtension.class)
public class SoftAssertionsAssertJBDDTest {

    @InjectSoftAssertions
    BDDSoftAssertions bdd;

    @Test
    public void soft_assertions_extension_bdd_test() {
        //Some block of code getting variable1
        bdd.then(variable1).as("variable1 is wrong").isEqualTo({what we expect from variable1});
        //Some block of code getting variable2
        bdd.then(variable2).as("variable2 is wrong").isEqualTo({what we expect from variable2});
        //Some block of code getting variable3
        bdd.then(variable3).as("variable3 is wrong").isEqualTo({what we expect from variable3});
        ...
    }
}

或

@ExtendWith(SoftAssertionsExtension.class)
public class SoftAssertionsAssertJTest {

    @Test
    public void soft_assertions_extension_test(SoftAssertions softly) {
        //Some block of code getting variable1
        softly.assertThat(variable1).as("variable1 is wrong").isEqualTo({what we expect from variable1});
        //Some block of code getting variable2
        softly.assertThat(variable2).as("variable2 is wrong").isEqualTo({what we expect from variable2});
        //Some block of code getting variable3
        softly.assertThat(variable3).as("variable3 is wrong").isEqualTo({what we expect from variable3});
        ...
    }
}

它看起来更容易理解然后写许多步骤验证在一行

木星的Asertall距离我们最近：https://junit.org/junit5/docs/current/user-guide/#writing-测试断言。

它允许执行多个断言语句，并一起报告它们的结果。如：

@Test
void groupedAssertions() {
    // In a grouped assertion all assertions are executed, and all
    // failures will be reported together.
    assertAll("person",
        () -> assertEquals("Jane", person.getFirstName()),
        () -> assertEquals("Doe", person.getLastName())
    );
}
