Automation makes testing efficient, reducing costs and freeing up resources. Test early, test often is the dev ops mantra and automating testing makes this possible - a true shift left in the SDLC.

  • Efficiency – Much quicker to execute than equivalent manual test.

  • Repeatability –  The results can be compared and trusted knowing the test is performed properly every time.

  • Reusability – once the scripts have been written they can be used time and again.

  • One script can execute multiple test cases.

  • Requires Investment – tools, infrastructure, frameworks, scripts, automation experts.

  • Not all tests are suitable for Automation - we can help you evaluate and calculate the return on investment.

Companies need to replace their applications from time to time, migrating data from the existing source application to the new application.  But how do you check that all data has been migrated correctly?

  • We work with you to identify the mapping of data, build and apply mapping rules.

  • We can migrate data from one or more legacy applications to a new application.

  • Our rules-based engine maps and processes the data, backed up by test automation,  to validate the conversion and provide an audit path.

  • We verify and improve data during migration, identifying data gaps, inconsistencies and duplicates.

  • We verify data after a migration to provide assurance in data integrity.
