Let's talk about how to plan weekly during the project. There are nine project modules. Using object-oriented programming and paypal console test, object-oriented analysis, object-oriented design, implementation: these nine modules will make you a four step development process. Almost 80% of the time will go to the PayPal console for execution. One of the characteristics of this development is that you will implement the writing of test cases ahead of time. We hope this will give you a clear understanding of what is expected from PayPal's console. The following is the layout of the nine modules. Module 1 and 2: Object Oriented Analysis and PayPal's console object-oriented design implementation and testing module 3 and 4: create a new Alipay account module five: the main screen and account activation module 6 of the account: add and extract capital module 7: send request and capital module 8: improve PPAccountScreen module 9: generate system status report module 10: Test and demonstration
