Here are some facts about the Silk Test tool: Skill tool is developed for performing regression and functionality testing of an application. Silk Test helps in preparing the test plan and managing it to provide direct accessing of the database and validation of the field. On the basis of which factors you would consider choosing automated testing over manual testing? Choosing automated testing over manual testing depends on the following factors: Tests require periodic execution. Tests execute in a standard runtime environment. Automation is expected to take less time. Automation is increasing reusability. Automation reports are available for every execution. Small releases like service packs include a minor bug fix. In such cases, executing the regression test is sufficient for validation. Tell me the key elements to consider while writing a bug report. An ideal bug report should consist of the following key points: A unique ID Defect description: A short description of the bug Steps to reproduce: They include the detailed test steps to emulate the issue.

What is the difference between performance testing and monkey testing? Performance is identified with achieving response time, throughput, and resource-utilization levels that meet the performance objectives for a project or a product. Monkey testing is a technique in software testing where the user tests the application by providing random inputs, checking the behavior of the application or trying to crash the application. What is exploratory testing? Exploratory testing is an approach to software testing, wherein testers learn simultaneously about the test design and test execution. In other words, it is a hands-on approach where testers are involved more in the test execution part than in planning.

In addition, changes can be made with the IG. How to change the baud rate in CANoe without changing the code? In Autosar, we can use post build configuration for CAN baudrate values. What is environment variable? Answer: Hardware-in-the-loop HIL simulation is a technique that is used in the development and test of complex real-time embedded systems. HIL simulation provides an effective platform by adding the complexity of the plant under control to the test platform. The complexity of the plant under control is included in test and development by adding a mathematical representation of all related dynamic systems. The embedded system to be tested interacts with this plant simulation. Hardware-In-the-Loop System is an effective platform for developing and testing complex real-time embedded systems.

Real-Time Operating System is a multitasking operating system intended for real-time applications. In general, an operating system OS is responsible for managing the hardware resources of a computer and hosting applications that run on the computer. An RTOS performs these tasks, but is also specially designed to run applications with very precise timing and a high degree of reliability. This can be especially important in measurement and automation systems where downtime is costly or a program delay could cause a safety hazard. Some of these operations include OS calls and interrupt handling. Example: Imagine that you are designing an airbag system for a new model of car. In this case, a small error in timing causing the airbag to deploy too early or too late could be catastrophic and cause injury. Therefore, a hard real-time system is needed; you need assurance as the system designer that no single operation will exceed certain timing constraints.

On the other hand, if you were to design a mobile phone that received streaming video, it may be ok to lose a small amount of data occasionally even though on average it is important to keep up with the video stream. For this application, a soft real-time operating system may suffice. An RTOS can guarantee that a program will run with very consistent timing. Real-time operating systems do this by providing programmers with a high degree of control over how tasks are prioritized, and typically also allow checking to make sure that important deadlines are met. Operating systems such as Microsoft Windows and Mac OS can provide an excellent platform for developing and running your non-critical measurement and control applications.
