Use Mockito to verify that nothing is called after a method

I have two critiques to that approach... and please bear in mind that my knowledge of your context is almost nil, which means that what I suggest here might not work for you.

I've only once experienced a problem like the one you mentioned, and it was a symptom that there was too much coupling between the objects because the responsbilities were way to broad. Since then I use a Domain-Driven Design approach and I haven't had this problem again.

I prefer to use Test-Data Builders to create test data. This approach allows me to have a template of what I want to build, and just replace the bits I'm interested in the test. If you decide to go this way, I strongly suggest you to use a tiny library called Make-It-Easy that simplifies the creation of these builders.

And two suggestions

If you have some time, I suggest you to

  1. Watch a presetation called The Deep Synergy Between Testability and Good Design by Michael Feathers - Part of the talk is about something very similar to what you're experiencing.
  2. Read the book Growing Object-Orieted Systems, Guided by Tests (aka GOOS), it has all sorts of insights about how to write simple, amazing, testable code.

Continuous Integration explained with jenkins deployment

Continuous integration is a coding philosophy and set of practices that encourage development teams to make small code changes and check them into a version control repository regularly. Most modern applications necessitate the development of code across multiple platforms and tools, so teams require a consistent mechanism for integrating and validating changes. Continuous integration creates an automated way for developers to build, package, and test their applications. A consistent integration process encourages developers to commit code changes more frequently, resulting in improved collaboration and code quality.

Best 13 Tools To Test JavaScript Code

Unit and functional testing are the prime ways of verifying the JavaScript code quality. However, a host of tools are available that can also check code before or during its execution in order to test its quality and adherence to coding standards. With each tool having its unique features and advantages contributing to its testing capabilities, you can use the tool that best suits your need for performing JavaScript testing.

QA&#8217;s and Unit Testing &#8211; Can QA Create Effective Unit Tests

Unit testing is typically software testing within the developer domain. As the QA role expands in DevOps, QAOps, DesignOps, or within an Agile team, QA testers often find themselves creating unit tests. QA testers may create unit tests within the code using a specified unit testing tool, or independently using a variety of methods.
