Answer:
Unit testing is a software development process in which the smallest testable parts of an application, called units, are individually and independently scrutinized for proper operation. This testing methodology is done during the development process by the software developers and sometimes QA staff. The main objective of unit testing is to isolate written code to test and determine if it works as intended.
Unit testing is an important step in the development process, because if done correctly, it can help detect early flaws in code which may be more difficult to find in later testing stages.
Unit testing is a component of test-driven development (TDD), a pragmatic methodology that takes a meticulous approach to building a product by means of continual testing and revision. This testing method is also the first level of software testing, which is performed before other testing methods such as integration testing. Unit tests are typically isolated to ensure a unit does not rely on any external code or functions. Testing can be done manually but is often automated. It might be helpful
Answer:
Explanation:
This question will be solved with the help of diagram (see attachment)
Given:
Δ∅ = 0.50 degrees (correction)
BC = 800 mm
AC = 600 mm
Solution:
We use coordinate system with point C as origin (0,0)
Hence,
Point A = (600,0)
Point B = (0,800)
The change in length or displacement can be calculated BB' :
BB' = BC * tan (Δ∅) = (800 mm) * tan (0.5) = 6.9815 mm
Hence, Point B' = (-6.9815,800) and we calculate distance A and B
We calculate distance A and B'
