10 Unit Of Measurement Testing Together With Automation Tools Together With Libraries Coffee Programmers Should Learn
In concluding a couplet of weeks, I receive got written unopen to articles well-nigh what Java developer should acquire inwards 2019 e.g. programming languages, libraries, in addition to frameworks, but if yous receive got simply ane thing to improve or acquire in addition to thence that must live on your automation testing skills. Testing is ane of the disciplines which separates professional person developers amongst amateur ones. It's non well-nigh next TDD, BDD, or whatever testing methodologies but at the really minimum level, yous must write code to attempt your code automatically. Many Java developers write unit of measurement tests in addition to integration tests which automatically run during create time, mostly past times using continuous integration tools similar Jenkins or TeamCity.
If unopen to of yous thinking, why a programmer should focus on automation testing in addition to thence allow me say yous that the importance of automation testing is growing exponentially due to to a greater extent than awareness in addition to emergence of DevOps.
Companies by in addition to large prefer programmers who are expert at writing unit of measurement tests in addition to exhibit expert cognition of diverse unit of measurement testing frameworks, libraries, in addition to tools e.g. JUnit, Selenium, REST-Assured, Spock framework etc.
As a Java developer, nosotros piece of job on really unlike areas, starts from writing center Java code to creating JSP pages, writing REST APIs, in addition to sometimes fifty-fifty creating Groovy scripts for create automation. That's why nosotros also request to live on aware of unlike tools nosotros tin exercise to automate testing of unlike Java stuff.
For example, I alone knew JUnit for a long fourth dimension but when I had to attempt my JSP pages, I was clueless until I establish Selenium. Same goes amongst REST Assured because I unremarkably attempt my REST API using curl command, but REST Assured takes the unit of measurement testing of REST APIs to unopen to other level.
In this article, I am going to portion 10 of the best in addition to essential tools, frameworks, in addition to libraries which tin assistance Java developer writing unit of measurement tests in addition to integration tests on their diverse Java projects.
Almost all major IDEs similar Eclipse, NetBeans, in addition to IntelliJIDEA provides JUnit integration which way yous tin both write in addition to run the unit of measurement attempt right from those IDE.
Most of us are however using JUnit iv but JUnit v is already released in addition to in all likelihood the adjacent thing to hold off this year. You tin exercise JUnit for both unit of measurement in addition to integration testing in addition to it also supports Java 8 features.
Btw, if yous are a completely novel inwards the unit of measurement testing world, especially inwards Java unit of measurement testing in addition to thence this JUnit in addition to Mockito crash course is a expert starting point.
If yous are serious well-nigh writing an integration attempt for your REST API, in addition to thence yous must acquire the REST Assured and REST API Testing Automation: via REST Assured & HTTP Client course on Udemy is a expert house to start with, I receive got already joined this course of didactics in addition to volition position unopen to fourth dimension aside to acquire this tool inwards 2019.
It covers many aspects of REST API testing e.g. Automated REST API Testing using Rest Assured Java in addition to RESTful spider web service Testing via POSTMAN in addition to HTTP Client.
The gap betwixt JUnit in addition to TestNG has reduced because of using annotations from JUnit iv in addition to integrating the Hamcrest matchers every bit good but it's upwardly to you.
If yous determine to acquire TestNG for unit of measurement testing your Java code in addition to thence TestNG Complete Bootcamp For Beginners - Novice To Ninja is a expert course of didactics to start with.
It provides pace past times pace guide for learning TestNG Framework (Next Generation) to speed upwardly your automation goals
Mocking is ane of the essential technique of modern-day unit of measurement testing, every bit it allows yous to attempt your code inwards isolation without whatever dependency in addition to that's why I encourage every Java developer to acquire a mocking framework along amongst JUnit.

If yous select to stick amongst Mockito in addition to determine to acquire this framework in addition to thence Mockito Tutorial: Learn mocking amongst 25 Junit Examples is a expert course of didactics to start with.
When yous exercise Spock, your attempt volition snuff it to a greater extent than readable in addition to easier to hold in addition to thank yous to its JUnit runner, Spock is compatible amongst most IDEs, create tools, in addition to continuous integration servers.
Unfortunately, I didn't uncovering a useful course of didactics to acquire Spock framework but Java Testing amongst Spock book is a expert resources to start with.
It is ane of the most useful libraries for writing automated tests to Spring applications. It provides first-class back upwardly for writing unit of measurement in addition to integration tests to Spring-powered applications including MVC controllers.
There is also a Spring Test DbUnit that integrates the Spring Test framework amongst DbUnit in addition to a Spring Test MVC HtmlUnit which integrates the Spring Test MVC framework amongst HtmlUnit.
By using these tools yous tin easily attempt your Spring MVC application inwards an automated way.
It's non reliable to connect to Dev or UAT database for integration tests because anyone tin alter the information in addition to schema e.g. tables, stored physical care for in addition to it volition campaign your automated integration attempt to fail.
DbUnit is a JUnit extension that tin live on used to initialize the database into a known solid set down earlier each integration attempt in addition to ensure that the database contains the right data.
DbUnit has its ain issues, but it is a really useful tool because it helps us to dissever the attempt information creation from the tested code.
It is a keyword-driven testing framework that uses tabular attempt information syntax. You tin exercise it to attempt distributed, heterogeneous applications, where verification requires touching several technologies in addition to interfaces.
If yous determine to acquire this wonderful framework for integration attempt in addition to thence Udemy's Robot Framework Test Automation is a neat resources to start with. It's a two-part course of didactics which covers the basic in addition to advanced features of Robot framework.
That's all well-nigh unopen to of the essential unit of measurement testing in addition to integration testing tools, frameworks, libraries for Java developers. There are many to a greater extent than libraries which I receive got non included inwards this listing e.g. AssertJ, Hamcrest which tin assistance yous to write beautiful in addition to fluent attempt but direct things slowly.
To start with, acquire a tool or library which yous tin exercise inwards your day-to-day work, for example, if yous are working amongst Java UI in addition to thence yous should commencement acquire Selenium because in addition to thence yous tin focus on this tool more.
Similarly, if yous are working on REST APIs in addition to thence acquire REST Assured. Similarly, if yous are doing a lot of center Java work, in addition to thence JUnit v is in all likelihood the commencement library yous should look.
It doesn't affair much which tool to start commencement but brand certain yous pass unopen to fourth dimension to upgrade your skills inwards this New Year.
