I would like to share my "a-ha" moment: NPrinting allows to implement regression testing for QlikView that was so much requested from me in the last years.
-get some data (database, text files, Excels..)
-make a QlikView script loading data above
-make some charts and formulas
-using NPrinting make HTML reports. Nothing fancy, just a table with few columns of numbers
-add NPrinting filters to define a day, say yesterday (or January first ). The assumption is that past numbers do not change anymore.
-manually check the numbers
-rename the HTML file (ex "sales_report_finland_2015_01_01.html") to "reference_sales_report_finland_2015_01_01.html"
-make a batch file like the one bellow and run it !
rem refresh QlikView file
"C:\Program Files\QlikView\qv.exe" /r whatever.qvw
rem generate NPrinting reports
"C:\Program Files (x86)\NPrinting\Client\NPrinting.exe" /NprintingFile whatever.nsq /Job "regression test"
fc "sales_report_finland_2015_01_01.html" "reference_sales_report_finland_2015_01_01.html" > nul
if %ERRORLEVEL% NEQ 0 (
echo Sales Report regression test failed
The regression test will fail if:
Do you currently have other ways to implement regression testing ?
