dw.util.Assert

The Assert class provides utility methods for assertion events.

This class does not have a constructor, so you cannot create it directly.

static areEqual(arg1 : Object, arg2 : Object) : void

Propagates an assertion if the specified objects are not equal.

static areEqual(arg1 : Object, arg2 : Object, msg : String) : void

Propagates an assertion using the specified message if the specified objects are not equal.

static areSame(arg1 : Object, arg2 : Object) : void

Propagates an assertion if the specified objects are not the same.

static areSame(arg1 : Object, arg2 : Object, msg : String) : void

Propagates an assertion using the specified message if the specified objects are not the same.

static fail() : void

Propagates a failure assertion.

static fail(msg : String) : void

Propagates a failure assertion using the specified message.

static isEmpty(arg : Object) : void

Propagates an assertion if the specified check does not evaluate to an empty object.

static isEmpty(arg : Object, msg : String) : void

Propagates an assertion using the specified message if the specified check does not evaluate to an empty object.

static isFalse(check : boolean) : void

Propagates an assertion if the specified check does not evaluate to false.

static isFalse(check : boolean, msg : String) : void

Propagates an assertion using the specified message if the specified check does not evaluate to false.

static isInstanceOf(clazz : Object, arg : Object) : void

Propagates an assertion if the specified object 'arg' is not an instance of the specified class 'clazz'.

static isInstanceOf(clazz : Object, arg : Object, msg : String) : void

Propagates an assertion using the specified message if the specified object is not an instance of the specified class.

static isNotEmpty(arg : Object) : void

Propagates an assertion if the specified object is empty.

static isNotEmpty(arg : Object, msg : String) : void

Propagates an assertion using the specified message if the specified object is empty.

static isNotNull(arg : Object) : void

Propagates an assertion if the specified object is null.

static isNotNull(arg : Object, msg : String) : void

Propagates an assertion using the specified message if the specified object is null.

static isNull(arg : Object) : void

Propagates an assertion if the specified object is not null.

static isNull(arg : Object, msg : String) : void

Propagates an assertion using the specified message if the specified object is not null.

static isTrue(check : boolean) : void

Propagates an assertion if the specified check does not evaluate to true.

static isTrue(check : boolean, msg : String) : void

Propagates an assertion using the specified message if the specified check does not evaluate to true.

areEqual

static areEqual(arg1 : Object, arg2 : Object) : void

Propagates an assertion if the specified objects are not equal.

Parameters:

arg1 - the first object to check.

arg2 - the second object to check.

areEqual

static areEqual(arg1 : Object, arg2 : Object, msg : String) : void

Propagates an assertion using the specified message if the specified objects are not equal.

Parameters:

arg1 - the first object to check.

arg2 - the second object to check.

msg - the assertion message.

areSame

static areSame(arg1 : Object, arg2 : Object) : void

Propagates an assertion if the specified objects are not the same.

Parameters:

arg1 - the first object to check.

arg2 - the second object to check.

areSame

static areSame(arg1 : Object, arg2 : Object, msg : String) : void

Propagates an assertion using the specified message if the specified objects are not the same.

Parameters:

arg1 - the first object to check.

arg2 - the second object to check.

msg - the assertion message.

fail

static fail() : void

Propagates a failure assertion.

fail

static fail(msg : String) : void

Propagates a failure assertion using the specified message.

Parameters:

msg - the assertion message.

isEmpty

static isEmpty(arg : Object) : void

Propagates an assertion if the specified check does not evaluate to an empty object.

Parameters:

arg - the object to check.

isEmpty

static isEmpty(arg : Object, msg : String) : void

Propagates an assertion using the specified message if the specified check does not evaluate to an empty object.

Parameters:

arg - the object to check.

msg - the assertion message.

isFalse

static isFalse(check : boolean) : void

Propagates an assertion if the specified check does not evaluate to false.

Parameters:

check - the condition to check.

isFalse

static isFalse(check : boolean, msg : String) : void

Propagates an assertion using the specified message if the specified check does not evaluate to false.

Parameters:

check - the condition to check.

msg - the assertion message.

isInstanceOf

static isInstanceOf(clazz : Object, arg : Object) : void

Propagates an assertion if the specified object 'arg' is not an instance of the specified class 'clazz'.
For example, the following call does not propagate an assertion:

 
     var test = new dw.util.HashMap();
     dw.util.Assert.isInstanceOf(dw.util.HashMap, test);

But the following call will propagate an assertion:

 
     var test = new dw.util.Set();
     dw.util.Assert.isInstanceOf(dw.util.HashMap, test);

Note that 'clazz' can only be a Demandware API Scripting class.

Parameters:

clazz - the scripting class to use to check the object.

arg - the object to check.

isInstanceOf

static isInstanceOf(clazz : Object, arg : Object, msg : String) : void

Propagates an assertion using the specified message if the specified object is not an instance of the specified class.
For example, the following call does not propagate an assertion:

 
     var test = new dw.util.HashMap();
     dw.util.Assert.isInstanceOf(dw.util.HashMap, test);

But the following call will propagate an assertion:

 
     var test = new dw.util.Set();
     dw.util.Assert.isInstanceOf(dw.util.HashMap, test);

Note that 'clazz' can only be a Demandware API Scripting class.

Parameters:

clazz - the scripting class to use to check the object.

arg - the object to check.

msg - the assertion message.
