In the first part of the blog I defined the term “Implicit Testing” and discussed root causes for the need of implicit tests. In the second part I will focus on the disadvantages of such tests and on possible solution approaches with the goal to avoid these disadvantages.
In larger safety-critical projects, quite often I hear the following statement: “Well, the Requirement A is indirectly or implicitly proven with the test XY!” Do you know this sentence as well? Have you ever experienced what can happen in late project phases when you have tested many requirements indirectly? The blog defines the term in […]
If you are newly engaged in the area of functional safety, then you will encounter fairly quickly the terms “structural source code coverage” and “requirements”. The specification of technical systems by requirements is, of course, also common in non-safety-critical areas. By contrast, the subject structural source code coverage is almost unknown outside safety-critical projects. In […]
What is the Psychology of Testers? What qualities characterize good people working in the testing area? Well, you can define some criteria: expertise- and methods know-how are sure essential characteristics. In addition, they must have management skills and bring social skills. These are certainly necessary skills. However, it is missing an important point that I […]
Testing of Platforms are challenges! Do you develop platforms in embedded systems in order to offer more customer solutions without having to make a completely new development for each customer project? Or do you have used an embedded operating system in order to develop your application as independent as possible from the hardware? For the […]
Validation and verification is the topic within my more than 15 years in business. Often this is more of a hassle topic. Time is short. The number of unmanageable tests, review and analysis is high. Employees are not really motivating for the subject. The technical resources are not sufficient. In the opinion of management, the […]
Are you working on software projects wherein functional safety in getting more and more necessary? Perhaps you are already in the middle of a project and have to fulfill the demands out of the IEC 61508, ISO 26262 or comparable standards? If so you maybe familiar with the with the term Structural Source Code Coverage. […]
Think about the following situation: You are near the end of your safety-related project and you have established traceability between all the project artifacts. In an audit (e.g. Internal Quality Assurance, Customer, External Authority) you have to demonstrate which software requirements are developed from which System Requirements. Each software requirement is linked to one or […]
