Method Detail
Writes an error to the log if expression doesn't evaluate to boolean true.
The Mojo.require or Mojo.assert methods will do the same, except that require will throw an exception when their requirements aren't met. These are intended to be used in cases where framework code or application cannot reasonably continue if the requirements aren't met.
Example:
Mojo.assert(dogs > 3, "expected dogs to be greater than #{count}, but it was #{amount}", {count: 3, amount: dogs})
- Parameters:
- {Boolean} expression
- expression that must evaluate to true
- {String} message
- a custom message to use if the assertion fails. This message will be run through template evaluation against the messageProperies object, so you can include details of the assertion failure in the message.
- {Object} messageProperties
- object containing values to use with template evaluation.
- Returns:
- {String} the message that was written to the log.
Writes an error to the log if expectedArray fails the Prototype isArray method.
- Parameters:
- {Boolean} expectedArray
- object that must be an array
- {String} message
- a custom message to use if the assertion fails. This message will be run through template evaluation against the messageProperies object, so you can include details of the assertion failure in the message.
- {Object} messageProperties
- object containing values to use with template evaluation.
- Returns:
- the message that was written to the log

- {String} message
- a custom message to use if the assertion fails. This message will be run through template evaluation against the messageProperies object, so you can include details of the assertion failure in the message.
