Putting Together a Testing Team

As part of one of my consulting efforts, I worked with a mid-sized company that was looking to move toward a more agile manner of developing software. As with any shift in work style, there is some bewilderment and, for some, considerable anxiety. People are being challenged to leave their comfort zones and embrace a continuously changing, dynamic working environment. And, dare I say it, testing may be the most ‘disturbed’ of the software roles in agile development.

What Agile Testing (Actually) Is

So, now that the first installment of this two fold article has been published (hence you might have an idea of what Agile Testing is not in my opinion), I’ve started feeling the pressure to explain what Agile Testing actually means to me.

How To Use driver.FindElement And driver.FindElements In Selenium C#

One of the essential parts when performing automated UI testing, whether using Selenium or another framework, is identifying the correct web elements the tests will interact with. However, if the web elements are not located correctly, you might get NoSuchElementException in Selenium. This would cause a false negative result because we won’t get to the actual functionality check. Instead, our test will fail simply because it failed to interact with the correct element.

Considering Agile Principles from a different angle

In addition to the four values, the Agile Manifesto contains twelve principles that are used as guides for all methodologies included under the Agile movement, such as XP, Scrum, and Kanban.
