Perhaps you should try some spelling variations:
"by computational testing coverage on" » "by compositional testing coverage on" (Expand search), "by computational tests coverage on" (Expand search), "by computational tinking coverage on" (Expand search), "_ computational testing coverage on" (Expand search), "and computational testing coverage on" (Expand search), "by computational test coverage on" (Expand search), "by computational testing coverage of" (Expand search), "by computational testing coverage in" (Expand search), "by computational testing coverage and" (Expand search)
"using coding python python programming" » "using codigo python python programming" (Expand search), "using codigos python python programming" (Expand search), "using using python python programming" (Expand search), "using coding pythons python programming" (Expand search), "using coding piton python programming" (Expand search), "using coding pitons python programming" (Expand search), "using coping python python programming" (Expand search), "using coating python python programming" (Expand search), "using cooking python python programming" (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"by computational testing coverage on\") OR (\"using coding python python programming\"))~".
• Removing quotes may allow a broader search: (( by computational testing coverage on ) OR ( using coding python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("by computational testing coverage on") OR ("using coding python python programming"))*.
