Googlers in our Test Engineering group often speak at, and write for, forums on testing all over the world. This week our own Julian Harty has published an interesting article titled "Improving the Accuracy of Tests by Weighing the Results". In this piece, Julian says:

In software as in life there are things we notice that help confirm whether something is satisfactory or unsatisfactory. Let's call these things that affect our judgment of the results "factors." Some factors provide stronger indications than others. When using these factors to rate results, we will assign higher scores (or "weightings") to the stronger indicators. By assigning higher weightings to the stronger indicators, we enable these to have a stronger influence on the overall outcome.You can read the rest of the article on Stickyminds.com.
This is good stuff, Allen. Keep it up.
OdpovedaťOdstrániťWeighting results is an interesting way of automating smoke-test style testing, but one must not forget that in regular unit tests, Server Stubs and Mock Objects are available to emulate the volatile layer and get precise assertions.
OdpovedaťOdstrániťVery informative post. I appreciate the pragmatic advice. Thanks Allen.
OdpovedaťOdstrániťGood Posting. Was Very Useful.

Krico, we are always looking for people to join our team, and have testing positions in our Zurich office. You can find out more at Google.com/jobs.
