Unit tests are executed at different stages during the development life cycle. As mentioned in the first blog post of this series, MUnit for Java Programmers: Introduction, unit tests play an essential role in the implementation, maintenance, and evolutionary stages of a project’s life cycle. Tests can be executed during each of these stages and the results are collected and analyzed. Should the application pass the series of tests it will continue on its journey through the project’s lifecycle.
A test double is a term used to describe replacing a dependent component of the functionality that is being tested with a dummy version of the real component — similar to a stunt double, only for unit tests. The test double only needs to emulate the behavior of the original dependent component closely enough that the functionality being tested doesn’t detect it’s not using the real component.
Test fixtures, also known as a test context, sets up the conditions for a test to run. These test conditions will be a known good state that is specific to the code under test. When the test is completed, the state is restored or torn down. Conditions can be set up before a test suite executes and before a test runs. Test suites are extended further by parameterizing executions, enabling the same test to run different inputs.
It is no secret that migrating to Mule 4 from Mule 3 is a challenge. Mule 4 saw the biggest change in the Mule runtime since its inception. However, with this series of “Mule 4 migration made easy” blogs, I will attempt to soothe any pain you might feel while migrating and provide tips and tricks on how to make the best from Mule 4.
This is a guest blog from a member of our developer community. Dr. Roger Butenuth is a Senior Java Consultant at codecentric, he has been using Anypoint Platform for five years, with projects ranging from building simple SOAP routing/transformation to introducing the API-led approach to a Fortune 500 company.
Building Mule applications differs from coding in Java. Instead of typing all your code (with a lot of CTRL+space completion),
A core component of the continuous integration process, that includes the previously discussed test automation framework, is the build process. As soon as the developer commits the code to version control repository, the build tool compiles the source code runs unit and integration tests and generates feedback for the developers.
Traditional integration platforms could get away with providing some command line tools to automate the build and deployment of applications built on their platform. But in the modern world, integration platforms need to encompass the critical API management & cloud components as well, so the scope of continuous integration and continuous delivery tools are no longer just limited to integration applications only.
This also requires support for provisioning integration software and applications in private or public cloud platforms and capability to automate governance of deployed applications.
MuleSoft provides the most widely used integration platform for connecting any application, data source or API, whether in the cloud or on-premises. With Anypoint Platform®, MuleSoft delivers a complete integration experience built on proven open source technology, eliminating the pain and cost of point-to-point integration. Anypoint Platform includes CloudHub™ iPaaS, Mule ESB™, and a unified solution for API management™, design and publishing.
