An automated Oracle for verifying GUI objects
MetadataShow full item record
The promise of test automation - the automatic application of software inputs to find bugs - is tempered by the difficulty of automatically verifying behavior. Indeed, the lack of tools for behavior verification is a major factor in keeping automated testing out of the mainstream. This thesis develops a technique that aids automatic behavior verification for a particularly difficult problem: determining the correction of screen output. A methodology to capture and compare screen output is presented and a case study using Microsoft ® PowerPoint ® is described.
