New system has more files

The comparison of the output of two systems is even harder if the number of output files is different. For example if the new system has the output file split into multiple files.

With Spirit it is possible to group multiple files and compare them to another group of files. This means that you no longer need to merge large files into one file before comparison.

Attributes names are changed
What do you do if the new system has different labels for the same attribute? =more=>
Files have different levels of detail
What do you do if the new system has more or less detail in the output files than the production system? =more=>
Files have different format
What do you do if the files you want to compare have a different format? =more=>
Repeat the same comparison
When you are doing a user acceptance test, you want to set up the comparison and repeat it until the output files finally match. =more=>
