In general there is no accurate test as they only test for surface traits not cognitive functions which type is truly all about. For example according to MBTI type tests i am ENFP even though cogntive functions wise i am ENTP. I would say this test is pretty accurate though.
Keys 2 Cognition - Cognitive Processes
I agree with what you said.. There's no accurate test out there. You have to study and come to your own conclusion. Did that test give you "ENTP?" This test always tells me I'm xSTP, which is super goofy to me. My Se/Ne are very close but I'm definitely an "N" by far. My third suggestion was INTP.
I think the closest way to come to an accurate type is to study the functions yourself and order them from least to greatest. Then, take the tests to see if they agree with you. Something I noticed is that someone read to me characteristics of the functions and had me order them by how much I agreed with them. I noticed that Ti is always dominant or auxiliary and Fe/Te are always at the bottom of the 8. This seems to be in agreement with the functions tests I take.

Summary Analysis of Profile
By focusing on the strongest configuration of cognitive processes, your pattern of responses most closely matches individuals of this type:
ISTP
Lead (Dominant) Process
Introverted Thinking (Ti): Gaining leverage (influence) using a framework. Detaching to study a situation from different angles and fit it to a theory, framework or principle. Checking for accuracy. Using leverage to solve the problem.
Support (Auxilliary) Process
Extraverted Sensing (Se): Immersing in the present context. Responding naturally to everything tangible you detect through your senses. Checking with what your gut instincts say. Testing limits and take risks for big rewards.
If these cognitive processes don't fit well then consider these types:
ESTP, or
INTP
