Exploratory Test Automation TASSQ/KWSQA 2009 Exploratory Test Automation CAST August 4, 2010 Douglas Hoffman Cem Kaner Douglas Hoffman Cem Kaner Copyright © 2010 Why Tests Don't Pass

Source Material The content of this talk has been taken from work done by Cem and Doug on a book by the same name. Douglas Hoffman Cem Kaner Copyright © 2010

What Is Exploratory Test Automation? TASSQ/KWSQA 2009 What Is Exploratory Test Automation? Douglas Hoffman Cem Kaner Copyright © 2010 Why Tests Don't Pass

Considerations for Automation Theory of error Input data Sequential dependence Output data Comparison Detection Evaluation Troubleshooting Notification Retention Maintenance Relevant contexts Douglas Hoffman Cem Kaner Copyright © 2010

Disk Buffer Size Write random sized records Read random sized records Douglas Hoffman Cem Kaner Copyright © 2010

Database Record Locking Create random set of records Launch several threads to Select a random record Open record exclusive for random time, or Open record shared for random time Douglas Hoffman Cem Kaner Copyright © 2010

Exhaustive Testing Maspar sqrt Douglas Hoffman Cem Kaner Copyright © 2010

Reset Database Douglas Hoffman Cem Kaner Copyright © 2010

Simulator Generation Of Results Telenova example Maspar compiler example Douglas Hoffman Cem Kaner Copyright © 2010

SVD Generation SVD: the means to verify data is embedded into the data itself Database records example Data communication packets example Douglas Hoffman Cem Kaner Copyright © 2010

Database Links Modified database engine to verify forward and backward links Chose a schema Generated a number of records Generated random inserts, modifies, and deletes Used random values for field entries Douglas Hoffman Cem Kaner Copyright © 2010

Summary Not all automated tests have to do the same thing each time TASSQ/KWSQA 2009 Summary Not all automated tests have to do the same thing each time Many different ways to explore using automation Looking faster and more deeply Working in areas not humanly accessible Douglas Hoffman Cem Kaner Copyright © 2010 Why Tests Don't Pass
