Information technology, together with industrial machinery and processes, can assist in the design, implementation, and monitoring of control systems. One example of an industrial control system is a programmable logic controller (PLC). PLCs are specialized hardened computers which are frequently used to synchronize the flow of inputs from (physical) sensors and events with the flow of outputs to actuators and events.
Wi-Fi technology can be really fast and super simple to set up. Typically, home automation devices using Wi-Fi for communication can be quickly setup using an app, and will not require a hub or other interface for remote control from a smartphone or voice control - as the communication comes straight from your Wi-FI Router to the devices. There are limitations to the numbers of devices on Wi-Fi network, so if you don't plan on having a significant amount of home automation products, this is a good fit for you.
With the growing number of web-based applications this is changing, however, as verifying and testing web-based interfaces is easier and there are various tools that help with this, including free open source projects. Please see below for a list of popular and useful tools, projects, books and resources to get started with automated software testing.
Jones recommends flexible automation frameworks and cautions against using a framework limited to only UI testing, for example. Some test teams build their frameworks from scratch to satisfy the desired result of the test automation code and activities. According to Jones, most test automation initiatives fail due to the poor design of the test automation framework architecture for that project.
Discrete manufacturing plants adopted these technologies fast. The more conservative process industries with their longer plant life cycles have been slower to adopt and analogue-based measurement and control still dominates. The growing use of Industrial Ethernet on the factory floor is pushing these trends still further, enabling manufacturing plants to be integrated more tightly within the enterprise, via the internet if necessary. Global competition has also increased demand for Reconfigurable Manufacturing Systems.
Automation is, unsurprisingly, one of the two main characteristics of home automation. Automation refers to the ability to program and schedule events for the devices on the network. The programming may include time-related commands, such as having your lights turn on or off at specific times each day. It can also include non-scheduled events, such as turning on all the lights in your home when your security system alarm is triggered.
A growing trend in software development is the use of unit testing frameworks such as the xUnit frameworks (for example, JUnit and NUnit) that allow the execution of unit tests to determine whether various sections of the code are acting as expected under various circumstances. Test cases describe tests that need to be run on the program to verify that the program runs as expected.
A performance tool will set a start time and a stop time for a given transaction in order to measure the response time. But by taking that measurement, that is storing the time at those two points, could actually make the whole transaction take slightly longer than it would do if the tool was not measuring the response time. Of course, the extra time is very small, but it is still there. This effect is called the ‘probe effect’.
Additionally, these tools help to eliminate repetitive operations -- replacing the human element -- and do what might not be possible otherwise, such as complementing or cataloging, searching, and combining information in ways that are common for test and software development organizations. Application testing helps organizations find issues in their product before the customers do. The number of combinations one has to test for -- even the most trivial of programs -- can be staggering. A pair of nested for loops, for example, can have unique test cases that number in the millions.
One way to generate test cases automatically is model-based testing through use of a model of the system for test case generation, but research continues into a variety of alternative methodologies for doing so. In some cases, the model-based approach enables non-technical users to create automated business test cases in plain English so that no programming of any kind is needed in order to configure them for multiple operating systems, browsers, and smart devices.
The U.S. government, among many others, recognizes the unsung value of automation professionals. Support for the importance of automation to industry comes from the United States Senate Committee on Appropriations. On 30 June 2009, the committee submitted report language (including the excerpt shown below) to accompany the bill: H. R. 2847 (Commerce, Justice, Science and Related Agencies Appropriations Act, 2010) emphasizing the importance of automation to industry:
A test automation framework is an integrated system that sets the rules of automation of a specific product. This system integrates the function libraries, test data sources, object details and various reusable modules. These components act as small building blocks which need to be assembled to represent a business process. The framework provides the basis of test automation and simplifies the automation effort.
IBM helps clients around the world transform and manage functional and industry-specific processes to achieve intelligent digital operations. These services rely on AI, process automation and advanced analytics to help deliver higher quality processes at lower cost with less risk. IBM process automation services address the four fundamentals of process design.
