课程名称：IBM 大型机测试：确保企业系统的质量 课程概述： 欢迎参加由 Uplatz 提供的 IBM 大型机测试课程。本课程旨在介绍大型机测试的基本概念，包括对大型机系统和应用程序的功能、性能、安全性和可靠性进行验证和确认。大型机广泛应用于银行、保险、零售和电信等行业，承担着关键任务。测试目的是确保大型机应用能够处理大量数据和交易，保持系统的稳定性和性能。 大型机测试的工作原理： 大型机测试遵循结构化方法，类似于其他软件测试流程，但采用特定的工具和技术来满足大型机的需求。课程涵盖了以下几个方面： 1. 环境设置：配置大型机环境、建立对 z/OS、CICS、COBOL 程序和数据库（如 DB2）的访问。 2. 测试计划制定：定义测试目标、范围和需求，创建详细的测试计划，包括测试用例和数据要求的识别。 3. 测试用例设计：设计测试用例以验证功能和非功能需求，包括批处理、在线交易和集成场景。 4. 测试数据准备：使用接近生产环境的数据或合成数据模拟实际场景。 5. 测试执行：使用 JCL 脚本和在线系统的交互测试环境执行测试，监控日志、输出文件和系统性能。 6. 缺陷报告和调试：识别应用逻辑、数据库查询或系统配置中的缺陷，并使用缺陷跟踪工具进行报告和跟踪。 7. 回归和集成测试：执行回归测试以确保新更改未影响现有功能，并验证与外部系统或数据库的集成。 8. 性能和负载测试：在高交易负载下测试系统行为，以确保可扩展性和可靠性。 学习大型机测试的好处： 通过掌握大型机测试，您可以帮助确保全球一些最大组织的系统的可靠性和效率。此外，大型机测试在关键行业的需求量大，具备该领域的专业知识将为您打开职业机会的大门。 - 了解遗留系统与现代技术的结合，增强系统现代化项目的能力。 - 学会独特的测试技术，包括批处理、交易系统（CICS）以及特定于大型机的数据库（如 DB2）。 - 打下坚实的调试基础，提高复杂大型机程序的调试和错误管理能力。 - 获得 JCL、File-AID、TSO/ISPF 等工具的实践经验，使您符合行业需求。 - 在性能测试、批处理作业测试和大型机数据库测试等领域建立专业知识。 课程大纲： 模块 1：大型机测试简介 模块 2：大型机测试原则与风险管理 模块 3：测试基本知识与策略 模块 4：软件测试生命周期（STLC） 模块 5：常见问题与澄清 模块 6：大型机测试类型 模块 7：大型机测试的高级主题 模块 8：实践技能评估 本课程将为您提供所需的知识和技能，以应对现代企业对大型机测试的各种挑战，确保系统的质量和可靠性。
A warm welcome to the IBM Mainframe Testing: Ensure Quality in Enterprise Systems course by Uplatz.Mainframe Testing involves verifying and validating the functionality, performance, security, and reliability of mainframe systems and applications. Mainframes are used for mission-critical operations in industries like banking, insurance, retail, and telecommunications. Testing ensures that mainframe applications handle large volumes of data and transactions without errors, maintaining system stability and performance.How Mainframe Testing WorksMainframe testing follows a structured approach similar to other software testing processes but with specific tools and techniques tailored for mainframes:Environment SetupConfigure the mainframe environment with the necessary hardware, software, and testing tools.Establish access to systems like z/OS, CICS, COBOL programs, and databases such as DB2.Test PlanningDefine test objectives, scope, and requirements.Create detailed test plans, including the identification of test cases and data requirements.Test Case DesignDesign test cases to validate functional and non-functional requirements.Include scenarios for batch processing, online transactions, and integrations.Test Data PreparationUse production-like data or synthetic data to simulate real-world scenarios.Leverage tools like File-AID and TSO/ISPF for data creation and manipulation.Test ExecutionExecute test cases using tools like JCL scripts for batch processing or interactive testing environments for online systems.Monitor logs, output files, and system performance.Defect Reporting and DebuggingIdentify bugs or issues in application logic, database queries, or system configuration.Report and track defects using bug tracking tools.Regression and Integration TestingPerform regression tests to ensure new changes do not affect existing functionality.Validate integrations with external systems or databases.Performance and Load TestingTest the system's behavior under heavy transaction loads to ensure scalability and reliability.Benefits of Learning Mainframe TestingBy mastering mainframe testing, you can contribute to ensuring the reliability and efficiency of systems that are integral to the operations of some of the largest organizations globally.High Demand in Key IndustriesMainframes are widely used in banking, finance, insurance, and government sectors.
