Note : I already posted this question at [Stackoverflow][1] and someone already helped me to request to move my previous thread to [SQA stack exchange][2], but no one replied. So, I am so sorry for cross posting. Can someone tell me what is Test Architecture Design? I used with Test Design Specification and Test Case Specification but not haven't heard of Test Architecture Design document before. I'm not sure what should I write for this testing document. My project is about embedded software device. Then I need to re-engineer the device and produce Test Architecture Design. So far, I only got this slide as my references http://qualab.jp/materials/SOFTEC2012-2.pdf I need to deliver Test Architecture Design document before start creating another testing document such Test Design Specification..etc. Look like combination of static test + dynamic test (blackbox testing technique).
