Testing Standards, Testing Solutions, Testing Tools Ethernet, like LIN, is a product of competition in the automotive communication field, alongside the CAN bus. In specific areas, the former two are more suitable than the CAN bus. If we set aside R&D costs and focus solely on technical reasoning, the existence of both is justified. Technical … Read more
To work more efficiently Oscilloscopes are undoubtedly one of the greatest inventions in the field of testing and measurement. They present the microscopic world of signals to us, allowing us to observe closely, capture problems precisely, and discover potential issues, making them very useful for improving product quality. More than ten years ago, when I … Read more
In recent years, the research and application of Advanced Driver Assistance Systems (ADAS) technology have rapidly developed in various related fields, indicating that automobiles are quickly entering a new ADAS world. The application scenarios of ADAS require its related functions to undergo sufficiently reliable testing to ensure that autonomous vehicles can operate safely and without … Read more
This article mainly introduces the pin definitions, interface standards, boundary scan, and TAP controller of the JTAG bus. JTAG (Joint Test Action Group) is an international standard testing protocol (IEEE 1149.1 compatible), primarily used for internal chip testing. Most advanced devices now support the JTAG protocol, such as ARM, DSP, FPGA, etc. The standard JTAG … Read more
Click the above to follow us! Today, let’s talk about Rust’s testing framework. To be honest, testing always feels like a hassle when writing code, but it is really important. Rust has a built-in set of simple and easy-to-use testing tools that can help us easily write high-quality code. Let’s see how to use this … Read more
The voltage of electric vehicle batteries is increasing from 400V to 800V, and the voltage of large-scale energy storage system batteries is rising from 600V-900V to 1500V. Engineers face a dilemma when proposing hardware-in-the-loop (HIL) requirements for high voltage battery BMS: the number of battery cell channels versus the simulation effectiveness. When the number of … Read more
Recently, while looking at the TiDB source code, I found that it used failpoint for fault injection, which I found very interesting. It involves code generation and parsing the code AST tree for replacement to implement fault injection. I will also try to analyze it and learn how to parse the AST tree to generate … Read more
Today, I want to talk to you about a very interesting topic, especially in the context of modern distributed systems—Chaos Engineering and Fault Injection. This may sound a bit profound, but let me explain it in a simple way and practice it with Ruby code. The core idea of Chaos Engineering is: to actively create … Read more
HttpRunner is an open-source API automation testing framework designed to simplify API testing and performance testing. It supports writing test cases in YAML/JSON format, featuring high usability and strong extensibility, making it very suitable for testing engineers and developers. Below, we will introduce this testing framework from the following aspects: First, let’s intuitively experience the … Read more
