The following methods are to group multiple assertions and ensure that all of them are executed, even if one or more of the assertions fail.

public static void assertAll(Executable... executables) throws MultipleFailuresError
public static void assertAll(Stream<Executable> executables) throws MultipleFailuresError
public static void assertAll(String heading, Executable... executables) throws MultipleFailuresError
public static void assertAll(String heading, Stream<Executable> executables) throws MultipleFailuresError

Example

package com.logicbig.example;

import org.junit.jupiter.api.Test;
import static org.junit.jupiter.api.Assertions.*;

class AssertAllExamplesTest {

  @Test
  void testBasicMath() {
      assertAll("basic math",

          () -> assertNotEquals(0, 1)
      );
  }

  @Test
  void testVariousValues() {
      assertAll("values",
          () -> assertEquals("Hello", "He" + "llo"),
