课程简介

## Coursera 课程总结:静态测试在实现高投资回报率中的重要性 本课程由 QA Mentor 的 CEO Ruslan Desyatnikov 主讲,强调了静态测试在软件开发生命周期 (SDLC) 中的关键作用,以及它如何帮助企业显著提高投资回报率 (ROI)。 **课程核心观点:** * **静态测试的价值被低估:** 尽管静态测试耗时且需要管理层支持,但其重要性常被忽视,许多公司宁愿将时间投入到设计或编码中。 * **“未在谷歌找到”的公式:** 静态测试 > 更好的文档 > 更好的代码 > 更少的缺陷 > 更快的交付 > 更高的质量 > 更满意的客户。这个公式清晰地阐述了静态测试的连锁效应。 * **早期发现,成本效益高:** 静态测试能在需求收集阶段之后立即引入,能有效减少引入系统的缺陷数量。与传统测试相比,静态测试发现缺陷的成本低10-20倍。修复一个在传统测试中发现的缺陷可能需要5-20小时(甚至更多),而静态测试中的缺陷修复成本仅需30-60分钟(甚至更少)。 * **“左移”测试原则:** 课程将深入讲解“左移”测试的原理,即在SDLC早期就开始测试,从而在编写任何代码之前就发现并解决潜在问题。 * **全面的方法论:** 您将学习如何制定实现自有静态测试的方法论,该方法论可应用于任何组织。课程将涵盖对业务需求、功能需求、设计文档、原型、线框图、用例等的检查方法论。 * **实用的工具和资源:** 您将获得 QA Mentor 专有的清单,用于验证 SDLC 中的各种产物。此外,还将提供4个免费的静态测试清单,用于检查和验证用例、功能需求、原型和代码审查。 * **ROI 的量化和展示:** 课程将教授如何轻松向管理层展示静态测试的潜在 ROI,并在过程结束后提供实际的 ROI 数据,证明其巨大的成本节约效果。Ruslan Desyatnikov 将分享其如何通过静态测试帮助一家公司节省超过1000万美元的案例。 * **实践经验驱动:** 课程内容基于 Ruslan Desyatnikov 近20年在 HSBC、Citi、Sterling 等财富100强公司中积累的实际操作经验,而非单纯的理论知识。 * **直接互动:** 您将有机会通过电子邮件直接向 QA Mentor 的 CEO Ruslan Desyatnikov 提问,解决课程相关的任何疑问。 **谁应该学习?** 软件工程师、QA 工程师、开发经理、项目经理以及任何希望了解并实施静态测试以提高软件质量和业务 ROI 的专业人士。 **主要收获:** * 掌握静态测试的方法论,并能在实际工作中应用。 * 理解静态测试对于减少缺陷和提高交付速度的重要性。 * 学会量化和展示静态测试的 ROI,赢得管理层支持。 * 获得实用的静态测试工具和资源。 * 了解“左移”测试的优势和实施方法。 本课程投资将对您的职业发展和企业效益产生深远影响。

With only 25% of companies actually engaging in it, Static testing is frequently overlooked as a viable option. Many assume the time that would be spent static testing would be better spent on design or coding. They are correct that static testing is time consuming, can be costly, and that it requires complete buy-in from the management team. While not always easy, static testing is not nearly as costly as fixing the defects introduced by skipping this important step. Please remember this formula which you will not find anywhere on Google: Static testing > Better Documentation > Better Code > Fewer Defects > Faster Delivery > Higher Quality > Happier Customers Introduced right after the requirements gathering phase, static testing is crucial if you want to reduce the number of defects introduced to the system or application under test. After this course you will be able to use your own static testing methodology that can be implemented at any organization. You'll leverage QA Mentor's proprietary checklists to validate and verify every single artifact in the Software Development Life Cycle. You'll also learn how to easily show your management the potential Return on Investment (ROI) before the process begins, and then show them exact ROI afterwards. And believe me, they will be shocked on how much money you will save the company! You should know that the cost of a defect found during traditional testing is about 10-20x the cost of one found in static testing. That may seem exaggerated, but here's why that's true. It takes longer to fix a defect once it's been coded into a functioning system. Finding the defect may take hours of a tester's time, then additional hours to fix the defect that could involve more than one developer or DBA. Next, the fix must be verified by a tester once more. All totaled, a defect found during traditional testing can take 5 - 20 hours (or more) to fix and verify. Contrast that with finding that same defect in static testing. Fixing it requires no code changes and only takes 30 - 60 minutes, sometimes even less so the difference in cost is dramatic. In this 10 video lecture e-learning course, you will learn how to implement a static testing phase within your Software Development Life Cycle. You will learn how to start application testing before a single line of code is written and identify issues that would potentially be converted into functional defects if not detected in the Static Testing Phase. You'll learn the entire methodology behind inspection methods and static testing on business requirements, functional requirements, design documentations, prototypes, wireframes, use cases, etc. At the end of this course you will test your knowledge by taking 40 questions test. As part of this course you will receive 4 complimentary static testing checklists which you can use to inspect and validate Use Cases, Functional Requirements, Prototype and Code Reviews. Also as a bonus you will have a direct interaction with CEO of QA Mentor Ruslan Desyatnikov by asking any questions relating to course material via email. You'll learn the principal of shift-left testing, something few companies fully understand or are willing to invest in, and how to calculate ROI on static testing and impress your senior management. Find out how QA Mentor's CEO Ruslan Desyatnikov was able to save one company over 10 million dollars using these principals and methods by stopping design and development of multi-year platform while using static testing techniques. These are only a few of the many things you will learn that are based on real, hands-on experience instead of just textbook theories. Ruslan Desyatnikov is eager to share his secrets of Static Testing, gleaned from nearly 20 years of active QA experience implementing static testing in companies such as HSBC, Citi, Sterling, Sterling and several other fortune 100 companies. Invest in yourself and your future! You will be glad that you did.
