From cautious to supportive test ninjas
Software testing is a profession that is performed by many types of persons. If you look at the DISC quadrant or other variants, we can easily place test professionals in all four fields. When looking any further, it is more likely to divide specific testing profiles into a specific field of the quadrant. A test automation engineer has in most cases other characteristics than a test manager. 
 
Technical and non-technical curiosity
We can describe the testing attitude as a combination of different characteristics, completely unrelated to the acquired technical knowledge. One of the most prominent features is curiosity. Technical curiosity results in wanting to know how systems work and loving to interact in order to make the correct test plans, designs and cases. Curiosity towards the non-technical side of things is as important as test ninjas will start asking critical questions like: “Is this requirement ambiguous?”, “Did this work before?”  and “What does <fast> mean to the end user?”. 
 
Although <looking at the bigger picture> isn’t a typical characteristic of testers, it does play a big role in the quality of the delivered product. Questions like “Are we building the right thing?”, “Are we building the thing accurately?” and “Is this an important feature to the customer?” will help to detect problems before the go-live.
