[Software Testing]—Basic Process of Software Testing (1)
Interview question 1: Basic process of software testing
Software testing work is basically carried out according to the process shown in the figure below, which
mainly includes the following steps:
- Requirements survey: Comprehensively understand the system overview, schedule, functional requirements, performance requirements, quality requirements and testing requirements, etc. Develop a test plan based on system overview, estimates of personnel, time and effort required for the project, and project quotation.
- Test design: Complete test design according to the test plan, including the design of test cases, and review and improve the written test cases.
- Test execution: Execute test cases according to the test plan and track and manage bugs.
- After development and testing, the smoke test case is executed first. After the smoke test passes, other use cases are executed.
- During the execution of the test case, it is necessary to operate the system according to the steps of the test case and compare whether the actual results are consistent with the expected results. If the consistency test passes.
- If the actual results are inconsistent with the expected results and the test fails, you need to submit a bug and enter the bug management process. After the bug is corrected, regression verification is required to confirm that the correction has been made and there are no new problems.
- Regression testing of old functions.
- Test evaluation: Summarize the test work. Based on the test results, a test evaluation report is issued.
- Online: Monitor online products, discover and solve online problems in a timely manner.
Interview question 2: How should network protocols be tested?
Network protocol testing is a very important testing task because network protocols are the basis for data exchange in computer networks. When conducting network protocol testing, we need to pay attention to the following aspects:
- Communication protocol testing: This includes testing all layers of the network protocol stack, from the physical layer to the application layer, to ensure that the network protocol is working properly. During testing, we need to simulate various network environments and network traffic to ensure that network protocols can operate normally under different circumstances.
- Security testing: When testing network protocols, we need to pay attention to the security of the protocol to ensure that the protocol cannot be exploited by hackers or malicious users. In security testing, we need to test the encryption, authentication and authorization functions of the protocol to ensure the security of the protocol.
- Performance testing: When testing network protocols, we need to test the performance of the protocol to ensure that the protocol can operate normally under high load conditions. In performance testing, we need to test the throughput, response time, concurrency performance and other indicators of the protocol to ensure the high performance and scalability of the protocol.
- Compatibility testing: When testing network protocols, we need to test the compatibility of the protocol on different platforms and environments to ensure that the protocol can work properly in various network environments. In compatibility testing, we need to test the support of the protocol, such as different operating systems, browsers, and devices.
