java.lang.Objectorg.fest.assertions.api.Assertions
public class Assertions
Entry point for assertion methods for different data types. Each method in this class is a static factory for the type-specific assertion objects. The purpose of this class is to make test code more readable.
For example:
int removed = employees.removeFired();assertThat(removed).isZero(); List<Employee> newEmployees = employees.hired(TODAY);assertThat(newEmployees).hasSize(6);

public static void setRemoveFestRelatedElementsFromStackTrace(boolean removeFestRelatedElementsFromStackTrace)
Fail.setRemoveFestRelatedElementsFromStackTrace(boolean) so that Assertions offers a full
feature entry point to all Fest Assert features (but you can use Fail if you prefer).
public static void fail(String failureMessage)
Fail.fail(String) so that Assertions offers a full feature entry point to all Fest Assert
features (but you can use Fail if you prefer).
public static void fail(String failureMessage,

public static Properties extractProperty(String propertyName)
Properties.extractProperty(String) so that Assertions offers a full feature entry point to
all Fest Assert features (but you can use Fail if you prefer).
Typical usage is to chain extractProperty with from method, see examples below :
// extract simple property values having a java standard type (here String)
assertThat(extractProperty("name").from(fellowshipOfTheRing)).contains("Boromir", "Gandalf", "Frodo", "Legolas")
.doesNotContain("Sauron", "Elrond");
// extracting property works also with user's types (here Race)
assertThat(extractProperty("race").from(fellowshipOfTheRing)).contains(HOBBIT, ELF).doesNotContain(ORC);
// extract nested property on Race
assertThat(extractProperty("race.name").from(fellowshipOfTheRing)).contains("Hobbit", "Elf").doesNotContain("Orc");
public static MapEntry entry(Object key,
Object value)
MapEntry.entry(Object, Object) so that Assertions offers a full feature entry point to
all Fest Assert features (but you can use Fail if you prefer).
Typical usage is to call entry in MapAssert contains assertion, see examples below :
assertThat(ringBearers).contains(entry(oneRing, frodo), entry(nenya, galadriel));
