abstract fun canFormat(assertion: IAssertion): Boolean
Denotes whether this IAssertionFormatter was created to format IAssertions such as the given assertion or not.

this method returns true then formatGroup should be able to format the given assertion. On the other hand,
if it returns false then formatGroup should throw an UnsupportedOperationException.
The same applies for format where format should additionally throw an UnsupportedOperationException
if an IAssertionGroup is passed.

IAssertionFormatter can format such kinds or not.
Returns
