Automation of an automobile internal combustion engine bench calibration tests

Introduction (problem statement and relevance). The article presents the work on the automation of an internal combustion engine (ICE) calibration tests results on a motor stand. The relevance of the article is due to the high labor intensity of such tests, the complexity of documentation and decisionmaking based on the results of the work.Purpose of the study. This work is part of a comprehensive methodology, the purpose of which is to reduce the duration of tests and improve the calibration results quality of the vehicle’s power plant. The entire methodology description as a whole is also given in the publication.Methodology and research methods. The achievement of this goal is ensured with the help of special systems – INCA-FLOW (test automation) and ASCMO (processing results and optimization), produced by Bosch/ETAS. The approbation of the technique was carried out on a motor stand in the MADI training box in relation to the problem of forming an ignition timing map.Scientific novelty and results. As a result of the methodology application, a 4.8 times reduction in the motor tests duration takes place if 2 people work in manual mode at the test bench without interruption.At the same time, the variance of the adequacy of Sad of the torque empirical model Mk turned out to be, on average, 1.5 times less if the model was built according to the automated tests results. The obtained data indicated an improvement in the quality of measurements in the transition to automated test methods.From a scientific point of view, the most original part of the work is the application of the “Gaussian process” method to build empirical models. This method provides more accurate results than, for example, the traditional method of least squares.The practical significance of the work lies in the ability to considerably reduce routine actions on a motor stand, and the additional time spent on developing and testing a test scenario (program) is compensated for by the fact that scenario models can be used in the future for other similar tests. The proposed methodology makes it possible to cover a significant part of the internal combustion engine calibration tests. For example, you can apply it if you possess the preliminary information about the test object (basing on which you can draw up an experiment plan) and the engine is to be prepared either for a car road tests or tests under special conditions.

Cloud based Agile Methodology Test Automation for Web Application by Using Tanh Activated Clustering and Classification Model (TACC) in Machine Learning

Automatic functional tests are a long-standing issue in software development projects, and they are still carried out manually. The Selenium testing framework has gained popularity as an active community and standard environment for automated assessment of web applications. As a result, the trend setting of web services is evolving on a daily basis, and there is a need to improve automatic testing. The study involves to make the system to understand the experiences of previous test cases and apply new cases to predict the status of test case using Tanh activated Clustering and Classification model (TACC). The primary goal is to improve the model's clustering and classification output. The outcomes show that the TACC model has increased performance and demonstrated that automated testing results can be predicted, which is cost effective and reduces manual effort to a greater extent.

Development of Test Automation Framework for Printed Circuit Board Assembly

A Test Automation Framework is a bunch of rules or coding guidelines for test-process handling that is followed during coding. These are simple strategies that produce helpful results such as improved code re-usability, higher portability, diminished script support cost, reduced interdependency, higher interchangeability, and so on. This paper presents the development of a test automation framework for Printed Circuit Board Assembly (PCBA) to test the functionality and fault identification of the electronic circuit in the PCBA. It provides an integrated array of test and measurement Instruments which is automated using SCPI (Standard Command for programming Instrument) based commands to control test and measurement processes, making it simpler to configure and query. These test instruments imitate the environment in which the PCBA is to be deployed, which helps to observe its characteristics to determine whether it meets the expectation for which it was designed. Any possible variations in its characteristics due to fault are observed during testing and those faults are identified automatically using the data-driven fault analysis method.

INFORMATION RELIABILITY ENHANCEMENT METHODS

Information reliability is the property of information to reflect real-world objects with the necessary accuracy. The reliability of information is an essential characteristic of any communication system. It is found that in modern network architectures of test automation systems, the main problem in the field of enhancement of the reliability of information is the creation of methods aimed at solving the problem of enhancing the reliability for «real» time systems.

Test Automation of Web Application Login Page by Using Selenium Ide in a Web Browser

Selenium stands as open-source program apparatus aimed at computerization testing. Here, selenium-IDE (Integrated Developments Environment) Testing is investigated, which could be a remarkably vital movement in Program Improvement Handle. It is to look at and alter source code. A high-quality computer program can well be achieved by producing Compelling Testing. This Paper handles a critical in addition to the crucial issue of Program Testing. Testing can well be executed both manually and automatically. This paper sets to do Mechanization Testing through "Selenium". Test cases (TC) are consequently recorded with this web testing tool whilst the analyzer is entering the information in a web application screen.

TEST AUTOMATION TECHNOLOGY OF ANDROID APPLICATIONS USING THE WEBDRIVER PROTOCOL ON THE .NET PLATFORM

The article deals with the development of automated tests utilizing the WebDriver Protocol. The WebDriver and Appium technologies are analyzed, that allow implementation of automated tests of Android applications at the level of the graphical interface on the .NET platform. The most useful patterns in the development of GUI tests are investigated. The project architecture is proposed, which allows you to simply develop reliable and supported automated tests of mobile applications on the .NET platform.
