message - The message to display

isEqual

public static void isEqual(Object object1,
 Object object2,
 String message)

Determines whether the given two objects are equal (identity). If the two objects are not identical, then an Assert.AssertException is thrown

Parameters:

object1 - The first object used to be compared to the second object

object2 - The second object used to be compared to the first object

message - The expression's message that will describe the reason why the check failed

isFalse

public static void isFalse(boolean condition,
 String message)

Determines whether the given condition if false or true and if it is true then an Assert.AssertException is thrown.

Parameters:

condition - The condition to verify it is false

message - The expression's message that will describe the reason why the check failed

isNotNull

public static void isNotNull(Object object,
 String message)

Determines whether the given object is not null. If the object is null, then an NullPointerException is thrown

Parameters:

object - The value to check to not be null

isNull

public static void isNull(Object object,
 String message)

isTrue

public static void isTrue(boolean condition,
 String message)

Determines whether the given condition if true or false and if it is false then an Assert.AssertException is thrown.

Parameters:

condition - The condition to verify it is true

message - The expression's message that will describe the reason why the check failed

isValid

public static void isValid(Object object,
 String message,
 Object... choices)

Determines whether the given object is one of the given choices using identity check.

Parameters:

object - The object to find in the list of choices

message - The expression's message that will describe the reason why the check failed

choices - The list of valid choices
