Table Driven Testing in Scala

Scala, scalatest, Tech Blogs, , ,

Reading Time: 3 minutes As a software developer, I ensure to write unit tests for the code which I write (and at times the missing unit tests for the existing code). My aim has been to ensure to cover all the cases that arise out of the code written and therefore I face challenges in this too. Because of my endeavour to write a sufficiently strong test suite for Continue Reading

Finding elements using Appium Inspector

Quality Assessment (QA), , , ,

Reading Time: 4 minutes In the previous blog, we had seen how we can install Appium on our local system. So in this blog, we will see how we can use Appium inspector and find different types of elements in them. So lets first see why we require Appium inspector? Why Appium Inspector? Testing a mobile application and a web application is different from one another. The main difference Continue Reading

Mocking The Right Way

Reactive Architecture, Scala, Slick, Tech Blogs, Testing, Testing, Unit Testing, , , , ,

Reading Time: 3 minutes Mockito is a fun way to perform unit tests, but it’s true potential can only be realised if the underlying layers are designed in such a way that there is no interaction with the internal logic of other components of the application.

Integration testing using H2Database

Integration Testing, Scala, , ,

Reading Time: 3 minutes Need of Integration Testing For doing unit tests, We use to do mocking. Consider we call getUser(), it calls the DAO that’s been mocked and returns “John” for the name and “21” for the age, assembles them and everything is perfect. No need to actually unit test a database there.What if there is any bug in database operations. If you mocked the database you can Continue Reading

Monkey patching in NodeJS

Angular, AngularJS, API's, JavaScript, Node.js, React, Tech Blogs, Testing, Testing, Web Application, Web Services, , , ,

Reading Time: 3 minutes Hey guys, I am back with another blog in my series of blogs on mocking in nodeJS, so if you have read my last blog, in which we looked over how we can use sinon for testing in nodeJS to effectively mock and stub behaviours, so in this blog we would look over the concept of monkey patching to make things more testable, so let’s Continue Reading

Beginners Guide for Mocking in Scala

Scala, Unit Testing, , , , ,

Reading Time: 3 minutes We all must know how the unit test cases are one of the most important part of an application. If not? Then I must tell you that unit testing is one of the earliest testings which is performed on the unit of code and the earlier the defects are detected, the easier it is to fix. It reduces the difficulties of discovering errors contained in Continue Reading

Writing Independent Tests

Scala, , ,

Reading Time: 2 minutes What does it mean for a test to be independent? It means that a test should not depend upon the presence or absence of other tests, the order of the tests, or whether or not previous tests failed or not. It also means that the tests should not be dependent upon external things such environment variables, an internet connection, or the local time. Why is Continue Reading

Progressive Web App Testing with Cypress.io

Scala, , , , , , , , , , , , , ,

Reading Time: 4 minutes A few days back during a client presentation, we were discussing different tools that can help us to perform end to end testing of a web app developed on some emerging technologies like Ionic, React, Angular and Vue. I am a super fan of selenium for testing different web apps and also have used Protractor for testing some of the angular based applications but this Continue Reading

Integration Testing with H2

Scala, , ,

Reading Time: 3 minutes It goes without saying that testing code is essential, if you don’t want to have buggy code in production, but how can you test code that queries a database? One solution is an in-memory database, and a common in-memory database is H2. Here is some code that queries a database. More specifically the method getNumDistinctInColumn returns the number of distinct values in a specified column Continue Reading

Difference between Mockito and JMockit

Java, Scala, Testing, , ,

Reading Time: 2 minutes A Brief analysis on Mockito And Jmockit Mockito JMockit 1. We can achieve Static method/constructor mocking by the combination of Mockito with Powermock. 1. Static method/constructor can be mocked directly in JMockit. 2. The Mockito API contains several inconsistencies in the syntax used for invocations to mocked methods. In the record phase, we have calls like when(mock.mockedMethod(args))… while in the verify phase this same call Continue Reading
