/*
 The file format is simply a grouped listing of keywords
 Ungrouped entries at the beginning apply to the whole testcase
 Groups define testfunctions or specific test data to ignore.
 After the groups come a list of entries (one per line) that define
 for which platform/os combination to ignore the test result.
 All keys in a single line have to match to blacklist the test.

 mac
 [testFunction]
 linux
 windows 64bit
 [testfunction2:testData]
