On Manual Testing - No Fluff Just Stuff

On Manual Testing

Posted by: Venkat Subramaniam on May 29, 2008

I have been talking testing to several programmers and testers recently. One common observation is, at least among those I've spoken to, most software testing is manual. When I ask why, I hear "because somethings are hard to automate." OK, somethings are hard to automate, so we have close to zero automation is not right. They agree that manual testing is painful and not effective, yet continue to manally repeat it every day.

“Error rate in manual testing is comparable to the bug rate in the code being tested.”—Boriz Beizer.

Why not consider using tools like Selenim and Watir (or Watin)? Why not look at using tooks like FIT, FITNesse, easyb, ...?

The latter tools will force the UI to be as thin as paper, meaning, will push the business logic to layer below and enable automated tests.
You can realize this using patterns like MVP or Model View Presenter pattern.

What seems to be lacking is either the realization or the motivation to automate. I am calling on these testers to get angry if they are testing the software manually.

Testers should focus on authoring tests and not running them—they should leave the running for computers to do, automatically.

What's blocking you?
