Data-driven framework with selenium, Scala, and SBT

Reading Time: 4 minutes Hello everyone, in our last blog we saw that how we can execute ours test in headless mode and now in this blog we will see how we can achieve Data-driven framework with selenium, Scala, and SBT. Need for data-driven framework A data-Driven framework helps us in separating the test script logic and the test data from one another. It allows us to write test Continue Reading

Combining Gatling Reports

Reading Time: 4 minutes Hi guys, In this blog, we shall discuss about the report generation through Gatling and combining Gatling Reports. As you may already know, when we run a Gatling test the report gets generated automatically. However, you cannot compare the Gatling test report of two different tests in a single report unless you have the enterprise version of Gatling. I will try to explain an easy Continue Reading

Table Driven Testing in Scala

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

Beginners Guide for Mocking in Scala

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

Solr With Scala: Rest End Points with AKKA HTTP

Reading Time: < 1 minute Hello Folks, Today we will discuss about Solr, Scala with Akka-HTTP. We will create rest-endpoints and try to connect with Solr server with them. The basic idea behind using Akka-HTTP for creating Rest end points is modules implement a full server and client-side HTTP stack on top of akka-actor and akka-stream. We can customize these routes according to our use case. We will talk step Continue Reading

How to write test-case for Scala.js application

Reading Time: < 1 minute Few months ago, I created a web application ‘Weather Report‘, based on Scala.js.  In this blog, I have explained how we can test our Scala.js application. Since I am still exploring it, so I took help from scalajs-tutorial.  I have used µTest as testing library. // uTest settings libraryDependencies += “com.lihaoyi” %%% “utest” % “0.3.0” % “test” testFrameworks += new TestFramework(“utest.runner.Framework”) Here is example of test-cases: def tests = Continue Reading

Testing Scala Applications with In-memory mongoDB

Reading Time: 2 minutes Is your test suite taking a large amount of time to run just because your methods need some database queries to be handled? Testing with In-memory databases can save a hell lot of time. In-memory database makes the queries readily available to methods in a matter of milliseconds. In case you are using mongoDB, this blog can help you run your test suite much faster Continue Reading

Mock Unit Testing using Mockito in Play Scala project

Reading Time: 2 minutes During Unit Testing in a Play Scala project, there arises a need to Mock certain Objects or Traits which are used in the unit, so that the unit being tested has a consistent interaction with its outside dependencies. But due to tight coupling or external dependencies, objects cannot be tested as a unit. So, we need to mock those external dependencies by adding fake external Continue Reading
