Development Stage:

The team will carefully design algorithms to implement the program code once the analysis and designing decisions have been made. The team writes the real code at one of the time-consuming stages.

Testing: 

The team conducts testing to ensure that the code complies with the specified product requirements before proceeding to the final step. The program is examined using a variety of manual (penetration) testing and automation testing techniques. When the program is fault-free and capable of upholding quality standards, testing is declared complete. They must again develop fresh, accurate software if the test reveals an inaccuracy.
