Fisher's combination test

WebWhen we want to test combinations of values of data items, the data combination test (DCoT) is a very useful technique. Especially because this technique may achieve various levels of coverage so it can cater for coverage in cases of low, medium or high-quality risk levels. Approach. Coverage based - Data.
