[Pharo-project] TestCase>>#assert:equals: optimization

by Stefan Marr

Hi: While stepping through bytecodes, I noticed a slightly annoying inefficiency in the SUnit implementation. The description string in #assert:equals: is always computed, even if it is not necessary. While that might not be a performance problem, I find it rather distracting when I have to debug on the bytecode/VM level. Since there seem to be only 127 senders or so in the image, you will probably not notice a big performance gain. The change to compute the string only when necessary is below. Best regards Stefan PS: This is a resend, because the original mail seemed to have been lost, while the mailing list was down. !TestCase methodsFor: 'asserting' stamp: 'StefanMarr 3/13/2012 23:41'! assert: aBooleanOrBlock description: aStringOrBlock aBooleanOrBlock value ifFalse: [ | aString | aString := aStringOrBlock value. self logFailure: aString.

Just want to add, that in Pharo we refactored things a bit, so if you want to look for vm parameters, they are accessed via: Smalltalk vm parameterAt: xyz not Smalltalk vmParameterAt: look in VirtualMachine class for implementation.
