Topics Covered

Open Closed Principle (OCP)

iMocha’s SOLID principles test helps recruiters and hiring managers to evaluate candidate’s understanding about Open Closed Principle (OCP) which states entities such as classes, modules, functions, etc. In programming

Interface Segregation Principle (ISP)

Our test checks applicant’s knowledge about interface segregation principle which helps in creating general-purpose interface by avoiding adding unnecessary functions

Dependency Inversion Principle (DIP)

This test checks applicant’s understanding about Dependency Inversion Principle (DIP) which states that high-level modules should not depend on low-level modules

Single Responsibility Principle (SRP)

Our assessment validates applicant’s knowledge about Single Responsibility Principle (SRP) in SOLID principles which states that a class only performs one task at a time as single responsibility of task

Liskov Substitution Principle (LSP)

Our pre-employment test for SOLID principles evaluates candidate’s understanding about Liskov substitution principle which states that ability of replacing objects of a superclass with objects of its subclasses

SOLID

This test helps recruiters and hiring managers to evaluate candidate’s knowledge about SOLID principles which helps to solve problematic design patterns

Coupling

Our online test on SOLID principles evaluates candidate’s ability to reduce coupling of code

Inversion of Control

This test checks applicant’s knowledge about Inversion of Control (IoC) principle which helps to invert the flow of control as compared to traditional control flow

Violation in SRP

Our test evaluates candidate’s understanding about SRP violation when responsibilities start to collate with each other

Types of DI

This online test on SOLID principles assesses candidate’s proficient knowledge about DI and its types

DI Containers

Topic:

Implementing SOLID

Difficulty:

Hard

Q 1. You have created a set of services that implement the same API, but depending on the region, it implements different business logic. Also the services themselves must run in that region. How would you do this considering the liskov substitution principle?

You should use child services that run in each region, and each run different business logic

Each instance of API is a separate service, and polymorphic substitution is performed by a higher order service

Each instance of API is a separate service, and polymorphic substitution is performed by a lower order service

None of these

Q 2. You are designing the architecture of a new application, and would like to ensure polyglot persistence. How would you do this by leveraging open/closed nature of a service based architecture for your application?

The data store should be designed to be extensible

Several data store technologies can be used and advertised using a single API

The data store technology is encapsulated and hidden behind separate APIs

The data store technology is encapsulated and hidden behind a single API
