1. System Overview

The software testing and development training room is an important testing activity in the software development process, aiming to verify whether the integration and interaction between different software modules or components are normal. Comprehensive testing ensures that various modules work together correctly according to design requirements to achieve the functionality and performance of the entire software system. The following are the general processes and steps of the software testing and development training room: 1. Test plan formulation: Determine the goals, scope, time and resources of comprehensive testing, and formulate corresponding testing strategies and testing methods. 2. Integration test environment construction: Prepare the test environment for integration testing, including hardware, software, network and other necessary facilities and tools. 3. Module integration testing: First conduct integration testing on adjacent modules to ensure that the interfaces and data transmission between adjacent modules are normal. This stage usually uses drivers or stubs to simulate unavailable modules. 4. Bottom-up integration testing: gradually add new modules from bottom to top to test the integrated system. This process usually requires the use of an adapter or simulator to simulate the unfinished module. 5. Top-down integration testing: start from the top module and gradually add lower-level modules to test the entire system. This process usually requires the use of drivers to simulate the underlying modules that have not yet been completed. 6. Cross-testing: On the basis of module integration, cross-module testing is conducted to verify the performance of the system under various cross-functional functions and scenarios. 7. Data integrity and correctness testing: Test data transmission and processing to ensure that data will not be lost, damaged or tampered with during the integration process. 8. Interface testing: Focus on testing the interfaces between various modules to verify the correctness of data transmission and interaction. 9. Performance testing: Test the performance indicators of the system, such as response time, throughput, concurrency, etc., to ensure that the system can work normally under the expected load. 10. Error handling and recovery testing: Test the system's ability to handle and recover from error conditions and exceptions. 11. Documentation and defect repair: Record test results, including defects and problems found. The development team performs defect fixes and performs iterative testing until the problem is resolved. 12. Test report and summary: Write a comprehensive test report to summarize the results, problems and lessons learned from the test activities to provide reference for subsequent testing and maintenance.

Software testing and development training room is an iterative process that requires continuous testing and repair. Comprehensive testing can ensure smooth integration between different modules, reduce system failures and performance issues, and improve overall software quality.

It can also give full play to the advantages of virtualization and reduce the number of physical workstations. , and a software testing workspace that reduces the energy consumption of customers' IT systems and improves space usage efficiency. Security is a core challenge in any server implementation. Servers hosting multiple virtual machines (VMs), also known as consolidated servers, not only bear the same security risks as non-consolidated servers, but also face the challenge of administrator role separation. Software testing platforms help improve the security of consolidated servers and address administrator role separation challenges. This is achieved through the following features: powerful partitioning capabilities, hardware-level security, Windows Server virtualization, network security features and a minimal trusted computing foundation. Server virtualization enables workloads with different resource requirements to coexist on the same host server. The software testing platform greatly improves the utilization of physical resources of the host server through flexible memory allocation, dynamic hardware addition and flexible network configuration: the software testing platform adopts a lightweight, low-overhead virtualization architecture based on a 64-bit hypervisor. Multi-core support can allocate up to 8 logical processors to each VM, supporting both 64-bit host and guest operating systems. In addition, server hardware technology is used to open the path from GuestOS to real hardware resources to avoid IOmapping at the VMM layer. , the long process of instruction conversion and data migration, reducing 80% of the performance loss caused by virtualization applications; in possible deployments of data centers and remote branch installations, powerful management functions and automation functions are needed to fully realize virtualization and reduce costs. possibility. The software testing platform meets this need through scalable management, interfaces for VM management, and PowerShell scripts and Group Policy Object (GPO) management and automation functions; at the same time, the hardware platform monitoring and management system can meet end-to-end full management.
