In final a brace of weeks, I receive got written roughly articles close what Java developer should acquire inwards 2019 e.g. programming languages, libraries, in addition to frameworks, but if y'all receive got simply i thing to improve or acquire thence that must move your automation testing skills. Testing is i of the disciplines which separates professional person developers alongside amateur ones. It's non close next TDD, BDD, or whatever testing methodologies but at the real minimum level, y'all must write code to assay out your code automatically. Many Java developers write unit of measurement tests in addition to integration tests which automatically run during construct time, mostly past times using continuous integration tools similar Jenkins or TeamCity.
If roughly of y'all thinking, why a programmer should focus on automation testing thence allow me say y'all 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 practiced at writing unit of measurement tests in addition to present practiced 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 real unlike areas, starts from writing heart in addition to soul Java code to creating JSP pages, writing REST APIs, in addition to sometimes fifty-fifty creating Groovy scripts for construct automation. That's why nosotros also bespeak to move aware of unlike tools nosotros tin exercise to automate testing of unlike Java stuff.
For example, I entirely knew JUnit for a long fourth dimension but when I had to assay out my JSP pages, I was clueless until I flora Selenium. Same goes alongside REST Assured because I commonly assay out my REST API using curl command, but REST Assured takes the unit of measurement testing of REST APIs to roughly other level.
In this article, I am going to part 10 of the best in addition to essential tools, frameworks, in addition to libraries which tin attention 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 agency y'all tin both write in addition to run the unit of measurement assay out right from those IDE.
Most of us are yet using JUnit iv but JUnit five 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 y'all are a completely novel inwards the unit of measurement testing world, peculiarly inwards Java unit of measurement testing thence this JUnit in addition to Mockito crash course is a practiced starting point.
If y'all are serious close writing an integration assay out for your REST API, thence y'all must acquire the REST Assured and REST API Testing Automation: via REST Assured & HTTP Client course on Udemy is a practiced house to start with, I receive got already joined this course of teaching in addition to volition seat roughly 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 equally good but it's upward to you.
If y'all determine to acquire TestNG for unit of measurement testing your Java code thence TestNG Complete Bootcamp For Beginners - Novice To Ninja is a practiced course of teaching to start with.
It provides pace past times pace guide for learning TestNG Framework (Next Generation) to speed upward your automation goals
Mocking is i of the essential technique of modern-day unit of measurement testing, equally it allows y'all to assay out your code inwards isolation without whatsoever dependency in addition to that's why I encourage every Java developer to acquire a mocking framework along alongside JUnit.
My favorite mocking framework is Mockito but if y'all similar y'all tin also explore PowerMock or JMock.
If y'all conduct to stick alongside Mockito in addition to determine to acquire this framework thence Mockito Tutorial: Learn mocking alongside 25 Junit Examples is a practiced course of teaching to start with.
When y'all exercise Spock, your assay out volition croak to a greater extent than readable in addition to easier to keep in addition to thank y'all to its JUnit runner, Spock is compatible alongside most IDEs, construct tools, in addition to continuous integration servers.
Unfortunately, I didn't notice a useful course of teaching to acquire Spock framework but Java Testing alongside Spock book is a practiced resources to start with.
It is i of the most useful libraries for writing automated tests to Spring applications. It provides first-class back upward 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 alongside DbUnit in addition to a Spring Test MVC HtmlUnit which integrates the Spring Test MVC framework alongside HtmlUnit.
By using these tools y'all tin easily assay out 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 crusade your automated integration assay out to fail.
DbUnit is a JUnit extension that tin move used to initialize the database into a known solid set down earlier each integration assay out in addition to ensure that the database contains the right data.
DbUnit has its ain issues, but it is a real useful tool because it helps us to carve upward the assay out information creation from the tested code.
It is a keyword-driven testing framework that uses tabular assay out information syntax. You tin exercise it to assay out distributed, heterogeneous applications, where verification requires touching several technologies in addition to interfaces.
If y'all determine to acquire this wonderful framework for integration assay out thence Udemy's Robot Framework Test Automation is a dandy resources to start with. It's a two-part course of teaching which covers the basic in addition to advanced features of Robot framework.
That's all close roughly 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 attention y'all to write beautiful in addition to fluent assay out but conduct things slowly.
To start with, acquire a tool or library which y'all tin exercise inwards your day-to-day work, for example, if y'all are working alongside Java UI thence y'all should showtime acquire Selenium because thence y'all tin focus on this tool more.
Similarly, if y'all are working on REST APIs thence acquire REST Assured. Similarly, if y'all are doing a lot of heart in addition to soul Java work, thence JUnit five is in all likelihood the showtime library y'all should look.
It doesn't affair much which tool to start showtime but brand certain y'all pass roughly fourth dimension to upgrade your skills inwards this New Year.
