10 Unit Of Measurement Testing As Well As Automation Tools As Well As Libraries Coffee Programmers Should Learn
In terminal a couplet of weeks, I conduct hold written roughly articles nearly what Java developer should larn inward 2019 e.g. programming languages, libraries, as well as frameworks, but if yous conduct hold but i thing to improve or larn as well as hence that must move your automation testing skills. Testing is i of the disciplines which separates professional person developers amongst amateur ones. It's non nearly next TDD, BDD, or whatever testing methodologies but at the rattling minimum level, yous must write code to essay your code automatically. Many Java developers write unit of measurement tests as well as integration tests which automatically run during create time, mostly past times using continuous integration tools similar Jenkins or TeamCity.
If roughly of yous thinking, why a programmer should focus on automation testing as well as hence permit me nation yous that the importance of automation testing is growing exponentially due to to a greater extent than awareness as well as emergence of DevOps.
Companies to a greater extent than frequently than non prefer programmers who are skillful at writing unit of measurement tests as well as present skillful cognition of diverse unit of measurement testing frameworks, libraries, as well as tools e.g. JUnit, Selenium, REST-Assured, Spock framework etc.
As a Java developer, nosotros piece of work on rattling dissimilar areas, starts from writing amount Java code to creating JSP pages, writing REST APIs, as well as sometimes fifty-fifty creating Groovy scripts for create automation. That's why nosotros also need to move aware of dissimilar tools nosotros tin job to automate testing of dissimilar Java stuff.
For example, I exclusively knew JUnit for a long fourth dimension but when I had to essay my JSP pages, I was clueless until I constitute Selenium. Same goes amongst REST Assured because I commonly essay 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 portion 10 of the best as well as essential tools, frameworks, as well as libraries which tin tending Java developer writing unit of measurement tests as well as integration tests on their diverse Java projects.
