The presence of open
source makes programming easy and provides an out of the box ability to let
young Java developers modify the apparatus by their own. The tools with open
source support can be expanded with new plugins and extensions. And most
importantly, they can be reached through a variety of operating systems. We are
here covering top five open source tools that you as a Java developer can use
to create new experiences on your existing or new developments.
1 1) Eclipse:
Eclipse is perhaps the
most used integrated development environment (IDE) for developing Java applications. No matter whether you want to develop some apps for Android or
write some programs for software like Mathematica, Eclipse is an integrated
solution for you. It has a large number of plugins. Additionally, it recently
debuted within Microsoft’s Visual Studio to ease your development. Eclipse SDK is
available as a free and open source (FOSS) software. It is not compatible with
the original GNU General Public License. However, it uses GNU Classpath and can
run under IcedTea project.
2) Chef:
Chef is a Ruby-based
configuration management tool that offers you an easy way to configure your
development or production environment right on your premise. You can also
integrate tasks into cloud-based platforms such as Amazon EC2, Google Cloud Platform, Open Stack or Microsoft Azure. Scripts written by Chef are
known as recipes and their groups are being called cookbooks. The tool uses
Ruby as the base of its scripts to provide you a generic scripting language for
enabling automated infrastructure activities.
3) JUnit :
JUnit is a unit testing
framework for Java developments. It allows you to write and run unit tests that
help in examining class, method and functionality of your codes. Cross-platform JUnit is
based on x Unit architecture. You can access its code directly from GitHub to
modify its usage. There are some specific annotations that JUnit uses to run your
unit tests. For instance, you have to use to test methods and Before or After to define a particular method for execution before or after each of your
test methods.
4) Mockito:
Mockito is a mock testing framework for Java. It lets you verify the behavior of the system under test (SUT) without any prior expectations and enables the creation, verification and stubbing of mocks. Abilities such as readable tests and verification errors make Mockito one of the most popular testing tool. It has its presence on GitHub to enable modifications in its source code.
5) Flyway:
Flyway works as an open source database migration tool. It has a command-line client as well as a Java API, Maven, Gradle and SBT plugins and Ant tasks. Databases that are supported through Boxfuse-developed Flyway include Oracle, SQL Server, SQL Azure, MySQL, MariaDB, Google Cloud SQL, Sybase ASE and Phoenix among others.
