This test harness helps in testing the compliance matrix without creating the actual media. It parses a text file which specifies the matrix in sections. Each section name starts with '[' and ']'. The '#' character is used as string separator. Some well known sections are [type#values], [var#values], [suite#values] and [error#vaules] etc. These sections define keys which can be used in the actual testcase. For e.g. [type#values] defines "pro=0x40" which indicates that product type professional's internal representation using DWORD is 0x40. The value sections need to be at the start of the test matrix text file. The other kind of sections which can be present in this test case matrix file are called "Test Sections". These sections contain the actual test cases. For e.g. [test#pro#5.0#2031#none#retail#fpp] win3x#3.1#950#none#any=typeerr,no win9x#9.5#950#none#any=none,yes ntw#3.1#1057#none#any=vererr,no indicates that the sections is for testing professional, version 5.0, build 2031, with not product suites and is of type FPP retail variation. Each line in this section indicates the target platform for which this media needs to be tested for upgrade. For e.g. win9x#9.5#950#none#any=none,yes Indicates that Windows 9X, version 9.5 and build number 950 with no product suites and of type any variation needs to pass on upgrade with this professional media. Another e.g. ntw#3.1#1057#none#any=vererr,no Indicates that NT workstation version 3.1, build number 1057, with no product suites and of type any variation, needs to fail on upgrade with version error with the given professional media.
