5.1.1 Run backend server Step 1: Clone or download the project from the Github link: https://github.com/ngotam1899/WebBanDienThoai.git Step 2: A folder named “WebBanDienThoai” will appear after cloning the project from Github or extracting the report attachment Proceed to the folder “WebBanDienThoai” Step 3: Open the application running backend (be-phonestore folder) After opening the project with Visual Studio Code, select "Terminal" on the taskbar, select "New Terminal" (Or simply press Ctrl + `) Step 4: After the integrated Command Line window appears, run the command "npm install" to update the missing libraries and packages on the machine that the Project needs Step 5: Run the command line “npm run dev” to initialize the backend server with PORT of 3000 5.1.2 Run frontend server Step 1: Open the application FE_WebBanDienThoi) and CMD_WebBanDienThoai) running front-end Sales page front-end Management page (folder (folder Do the same as steps 3, 4, We get: Chapter 5: IMPLEMENTATION AND TESTING 108 Run the command line “npm run dev” to initialize - [TellMe] E-commerce page - [TellMe] Administration page 5.1.3 Run chatbot server Step 1: Open the application running Chatbot (Chatbot folder) After opening the project with Visual Studio Code, select "Terminal" on the taskbar, select "New Terminal" (Or simply press Ctrl + `) Step 2: After opening the Command Line window, run the command “rasa run action” and `rasa run enable-api debug –cors “*”` in two different Command-Line windows to run the program 5.1.4 Run mobile app Step 1: Open the application running Mobile App (mobileapp folder) After opening the project with Visual Studio Code, select "Terminal" on the taskbar, select "New Terminal" (Or simply press Ctrl + `) Step 2: After the integrated Command Line window appears, run the command "npm install" to update the missing libraries and packages on the machine that the Project needs Step 3: After opening the Command Line window, run the command “npx react-native run-android” to run the app Testing 5.2.1 Overview This section mainly describes the method for planning, organizing, and managing the test process of the TellMe e-commerce system Chapter 5: IMPLEMENTATION AND TESTING 109 System testing helps to provide all the necessary information through the testing phases to make an assessment of the system based on

IMPLEMENTATION AND TESTING 118 Chapter CONCLUSION Results Good teamwork skills, team communication skills, analytical work when working on short-term projects Skills in searching documents, skills in finding solutions on the internet for problems in the process of building projects Know how to apply a non-relational database (No-SQL) to build a database for a system, build a REST API web server that can serve web applications and application transformation, build web interface as Single Page Application using ReactJS Strengths and Drawbacks 6.2.1 Strengths - The website is designed with an easy-to-see and user-friendly interface - Simple ordering and payment - By effectively suggesting products (items) for each user, will help users feel more convenient and interested in the website And this will help increase the profit for the store 6.2.2 Drawbacks - Regarding the interface, there are still many shortcomings in the design, so the website is compatible with the computer interface and there are still many pages that are still not good in the design - In terms of functionality, due to the lack of expertise and experience, the processing is still quite slow, the interface loads for a long time - Regarding the data issue, the data is quite small, mainly used for testing, so there are some cases where the data is larger, leading to slow browsing or unreasonable display data Lesson learned - Learn how to manage basic source control, very good support in doing multiperson projects Chapter 6: CONCLUSION 119 - Learn the techniques of MERN Stack which are very popular nowadays - Learn the flow to verify users when they register, log in - Learn the connections between the Servers, the Python application runs machine learning algorithms to integrate into the MERN Stack project - Learn to deploy servers through Heroku Future works After building and developing features for about months, the team came up with some ideas to develop a strong system and overcome some limitations in the system However, because there was not enough time, the team saved this idea and implemented it when there was time - Integrate more payment gateways such as VNPAY, Ngan Luong, - Build more voice chatbot features - Image-based corresponding product search function - The function of issuing revenue slips of the day - Installment invoice issuance function Chapter 6: CONCLUSION
