A developer needs to visually represent the logic of a program, including decisions (yes/no branches) and processes. Which tool should the developer use?

A developer is creating a cloud-based application that needs to authenticate third-party services before allowing access to its API. The developer decides to use a method where each third-party service receives a unique key that must be included in each API request. This method is known as:

During a sprint retrospective, the team identifies that too many bugs are being discovered late in the development cycle. They decide to introduce a practice where developers write tests for individual functions before coding the functions themselves. This approach is an example of:

A programmer writes a step-by-step description of a solution in plain English without using any specific programming language syntax. What is this description called?
