2024年1月6日 · 2 V&V模型、RIPR模型、MDTD 2.1 验证和确认模型（V&V） 为把握软件开发各个环节的正确性，需要进行各种确认和验证工作。 验证(Verification)，在软件开发过程的某个阶段，决定此时的产品是否满足前一个阶段所确定需求的过程。

错误（Error）：一个好的同义词就是mistake。 错误往往会传播； 故障（fault）：错误的具体表现，故障不一定是由编程错误引入的，也有可能是物理设备故障，系统设计错误和用户交互错误。 往往都是Error导致的. 软件测试是创新性的工作！ 软件测试的开销是不可忽略的（事实上甚至往往超过软件总开发成本的一半！ ），软件测试工程常常要在测试开销和测试效果（测试覆盖率）之间做trade-off. Reachability - 故障是可达的。 测试用例要能达到它就能让它运行. Infection - 故障会 …

RIPR. 如何设计测试用揭示程序错误？使用RIPR模型，设计测试用例的时候需要满足四个条件. Reachability（可达性）： 测试用例必须能够到达程序包含fault的地方; Infection（传染性）：必须导致内部状态错误出现

The RIPRNet (Releasable Internet Protocol Router Network) is a TCP/IP based computer network for joint Republic of Korea Armed Forces – United States Department of Defense access, analogous to the SIPRNet.

Example –RIPR (Error, Failure) Revisit the example, apply RIPR to design tests that •Reacha fault (i.e., execute the fault) •Cause the program state to be incorrect (i.e., error) •Propagate(i.e., failure) One possible test is [0, 4, 6] –now, design some more •How does RIPR model help designing tests? public static intnumZero(int[] arr)

Fault & Failure Model (RIPR) Four conditions necessary for a failure to be observed 1. Reachability: The location or locations in the program that contain the fault must be reached 2. Infection: The state of the program must be incorrect 3. Propagation: The infected state must cause some output or final state of the program to be incorrect 4.

2022年3月12日 · 本文是关于软件测试的学习笔记，重点讲解了测试基础，包括软件故障、错误和失败的区别，以及RIPR模型。介绍了junit自动化测试框架，包括其优势和工作流程，并探讨了测试覆盖度的重要性。

RIPR is an abbreviation of four necessary conditions to reveal software failure in testing, which is of great importance to understand fault triggering model and software testing principle. In the teaching course, we carry out the software test teaching reform based on RIPR model.

2020年10月21日 · RIPR-PD1 demonstrated enhanced inhibition of checkpoint blockade compared with ligand blocking by anti-PD1 antibodies, and increased therapeutic efficacy over anti-PD1 in mouse tumour...

We describe our empirical framework to assess various aspects of RIPR the model, including similar investigations into coincidental correctness and FEP of prior work, but also extending such investi-gatory scopes to assess other paths for a fault execution to possibly infect state, possibly propagate infection, and possibly be revealed.
