1To extract properties from objects use the org.assertj.core.api.Assertions#extracting(String...) method:2import static org.assertj.core.api.Assertions.assertThat;3public class EntryPointAssertions_extractProperties_Test {4  public void extracting_properties_from_objects() {5    Person person = new Person("John", "Doe", 30);6    assertThat(person).extracting("firstName", "lastName", "age")7                      .containsExactly("John", "Doe", 30);8    assertThat(person).extracting("name.first", "name.last", "age")9                      .containsExactly("John", "Doe", 30);10  }11  public static class Person {12    private String firstName;13    private String lastName;14    private int age;15    private Name name;16    public Person(String firstName, String lastName, int age) {17      this.firstName = firstName;18      this.lastName = lastName;19      this.age = age;20      this.name = new Name(firstName, lastName);21    }22    public String getFirstName() {23      return firstName;24    }25    public String getLastName() {26      return lastName;27    }28    public int getAge() {29      return age;30    }31    public Name getName() {32      return name;33    }34    public static class Name {35      private String first;36      private String last;37      public Name(String first, String last) {38        this.first = first;39        this.last = last;40      }41      public String getFirst() {42        return first;43      }44      public String getLast() {45        return last;46      }47    }48  }49}50To extract properties from objects use the org.assertj.core.api.Assertions#extracting(String...) method:51import static org.assertj.core.api.Assertions.assertThat;52public class EntryPointAssertions_extractProperties_Test {53  public void extracting_properties_from_objects() {54    Person person = new Person("John", "Doe", 30);55    assertThat(person).extracting("firstName", "lastName", "age")56                      .containsExactly("John", "Doe", 30);
