We can test business logic.
How about UI?

I don’t want to be dependent on the view.

• I must to divide and conquer.
• I must to reduce dependency.
• I must to make a class for single responsibility.
• I want to make test easily.

It has a view reference It has a view reference
Testability!

Android MVVMVinícius Tonial Sossella

The document discusses the Model-View-ViewModel (MVVM) design pattern. It describes MVVM as a pattern created in 2005 for building user interfaces that separates an application's business logic and data (the model) from its user interface (the view). The view model acts as an intermediary between the view and model, handling view logic and making data from the model available to the view. The document also discusses advantages like separation of concerns and easier testing, as well as disadvantages like complexity with larger applications. It then introduces Android Data Binding as a way to minimize glue code between views and view models through declarative bindings.

AngularJS – What, Why, Advantages and DisadvantagesWeblineIndia

AngularJS is a structural framework for building dynamic single-page web applications. It was developed by Google to overcome limitations of HTML for building interactive web apps. Some key advantages include dependency injection, data binding, and directives that automate code and simplify development. While useful for many applications, it also has some disadvantages like potential memory leaks and lack of support for older browsers. Overall, AngularJS can significantly reduce development time and costs for building complex web applications.

UI Design Patternsaamiralihussain

UI design patterns provide reusable solutions to common problems in user interface design. There are several types of design patterns including MVC, MVP, and MVVM. MVC separates an application into three components - the model, the view, and the controller. MVP is similar to MVC but replaces the controller with a presenter. MVVM builds on MVC and MVP by introducing a view model that acts as a mediator between the view and model layers. Design patterns improve maintainability, testability, and extensibility by reducing coupling between different application components.

MVVM in iOS presentationG ABHISEK

MVVM or Model - View - ViewModel is a design pattern aimed for modularising your code and build it on a Test Driven Development environment. When Apple's traditional MVC design pattern makes our controllers bulky and our unit tests painful, different design patterns such as MVVM, VIPER, MVP, etc come to our rescue. MVVM comes quite handy as it provides a loosely coupled mechanism between all components segregating your view, business and data logic.

Test-Driven DevelopmentEffectiveUI

Test-driven development involves writing unit tests before code to validate functionality. Unit tests help manage changes by continuously validating code correctness and allowing code to be changed safely. While some myths exist around unit testing, it can save significant time compared to finding and fixing bugs later. Setting up projects with separate code and test folders allows tests to run independently.

"Boiler Feed Pump (BFP): Working, Applications, Advantages, and Limitations E...Infopitaara

A Boiler Feed Pump (BFP) is a critical component in thermal power plants. It supplies high-pressure water (feedwater) to the boiler, ensuring continuous steam generation. ⚙️ How a Boiler Feed Pump Works Water Collection: Feedwater is collected from the deaerator or feedwater tank. Pressurization: The pump increases water pressure using multiple impellers/stages in centrifugal types. Discharge to Boiler: Pressurized water is then supplied to the boiler drum or economizer section, depending on design. 🌀 Types of Boiler Feed Pumps Centrifugal Pumps (most common): Multistage for higher pressure. Used in large thermal power stations. Positive Displacement Pumps (less common): For smaller or specific applications. Precise flow control but less efficient for large volumes. 🛠️ Key Operations and Controls Recirculation Line: Protects the pump from overheating at low flow. Throttle Valve: Regulates flow based on boiler demand. Control System: Often automated via DCS/PLC for variable load conditions. Sealing & Cooling Systems: Prevent leakage and maintain pump health. ⚠️ Common BFP Issues Cavitation due to low NPSH (Net Positive Suction Head). Seal or bearing failure. Overheating from improper flow or recirculation.

Process Parameter Optimization for Minimizing Springback in Cold Drawing Proc...Journal of Soft Computing in Civil Engineering

In tube drawing process, a tube is pulled out through a die and a plug to reduce its diameter and thickness as per the requirement. Dimensional accuracy of cold drawn tubes plays a vital role in the further quality of end products and controlling rejection in manufacturing processes of these end products. Springback phenomenon is the elastic strain recovery after removal of forming loads, causes geometrical inaccuracies in drawn tubes. Further, this leads to difficulty in achieving close dimensional tolerances. In the present work springback of EN 8 D tube material is studied for various cold drawing parameters. The process parameters in this work include die semi-angle, land width and drawing speed. The experimentation is done using Taguchi’s L36 orthogonal array, and then optimization is done in data analysis software Minitab 17. The results of ANOVA shows that 15 degrees die semi-angle,5 mm land width and 6 m/min drawing speed yields least springback. Furthermore, optimization algorithms named Particle Swarm Optimization (PSO), Simulated Annealing (SA) and Genetic Algorithm (GA) are applied which shows that 15 degrees die semi-angle, 10 mm land width and 8 m/min drawing speed results in minimal springback with almost 10.5 % improvement. Finally, the results of experimentation are validated with Finite Element Analysis technique using ANSYS.
