Based on different standpoints, the purpose of software testing of the system is different. From the perspective of users, it is hoped that through software testing, hidden errors and defects in the software can be exposed, so as to avoid economic losses and life losses for consumers and businesses after online use. inconvenient. Triggered from the perspective of a software developer, it is hoped that the test can show that the product does not have system errors and defects, verify that the product has indeed fulfilled the user’s requirements, establish the user’s confidence in the software quality, and improve the user’s reputation.

1.2 background

With the popularization of e-commerce, more and more people accept the convenient and fast transaction form of e-commerce, and the online food ordering system came out quickly and was welcomed by everyone. The application of the Internet has spread to thousands of households, which provides a good development space for online ordering. At the same time, the intuitive, effective, and convenient advantages of online meal ordering services are incomparable to traditional telephone ordering services. The survey data shows that white-collar workers are more willing to choose online meal ordering services. Online ordering will be a development trend for white-collar workers to capture restaurant information and order meals. Buying off-campus food has also become a major trend. With the growth of the Internet, online food ordering will gradually be loved by people, just like mobile phone text messages a few years ago, bringing tens of billions of business income to enterprises. In the Internet world, whoever innovates in applications earlier will grasp the direction of the future.

System Analysis Overview

2.1 System Requirements Analysis

There are two types of customers that this system mainly targets: consumers and merchants.

For consumers, consumers can use this system to order food online, inquire about ordering and delivery status, inquire about personal orders, and manage personal information such as phone numbers and delivery addresses.

For merchants, merchants can sell meals online, query historical orders, and count turnover through this system.

This system provides users with a takeaway ordering platform. The main target consumers are young people seeking convenience and busy workers. The main target businesses are various catering companies or self-employed.

3. System test design

3.1 Test plan

Test target:

(1) Make a realistic and comprehensive plan for each test activity, including the object, scope, method, progress and expected results of each test activity.

(2) Establish an organizational model for project implementation, and define the responsibilities and work content of each role in the test project.

(3) Develop an effective test model that can correctly verify the software system under development.

(4) Determine the time and resources required for testing to ensure its availability and effectiveness.

(5) Establish the test completion and test success criteria for each test phase, and the goals to be achieved.

(6) Identify various risks in testing activities, eliminate possible risks, and reduce losses caused by risks that cannot be eliminated.

Test content: test whether the functions of the software system are complete and effective, and whether the performance is up to standard. For merchants, there are 5 functional modules to be tested, 1: employee management module, to test whether the functions of administrators to add employees, edit employees and delete employees are effective; 2: category management module, to test whether the functions of store staff to add and delete Effective, for deleting a category, strictly pay attention to whether there is a dish under this category, if there is a dish, it should not be deleted; 3: the dish management module, to test whether the functions of the clerk to add dishes, edit dishes, prohibit the sale of dishes and delete dishes are effective; 4: Package management module, to test whether the functions of adding, editing, forbidding and deleting packages are effective; 5: Order details module, to test the function of merchants to view orders and query orders according to order number, start time and end time Is it accurate. For users, it is necessary to test whether the user login function, modify personal information, edit delivery address and place an order are valid. Among them, the order function must be strictly and thoroughly tested.

Test Plan:

1. Unit testing: To test each functional unit, adopt and white-box testing method, and the test cases should involve statement coverage, decision coverage, condition coverage and decision-condition coverage, which are completed by the coders themselves.

2. Integration test: test the integration of multiple functional units, using the black box test method, and the test case design adopts the equivalence partition method and the boundary value method.

3. System testing: Carry out functional, performance and security testing on the entire software system.
