I will write java spring boot unit tests using junit and mockito
Software Developer
About this Gig
Writing unit tests is rarely a developer's favorite task, but it is absolutely crucial for maintaining a healthy Spring Boot backend.
If you have a Java project and need to increase your code coverage, or if you just want to make sure your business logic doesn't break with the next update, I can help. I am a Java developer who actually enjoys diving into code maintenance and testing, so you can focus on building new features.
I will write clean, isolated, and reliable unit tests for your Spring Boot application using JUnit and Mockito. Whether it's testing your REST Controllers, business Services, or Repositories, I will make sure your logic holds up.
What you can expect from my work:
- Real Testing: I don't just test the "happy path." I look for edge cases and potential exceptions.
- Proper Isolation: Correct use of Mockito to mock dependencies so we are actually doing unit testing, not integration testing.
- Clean Code: Well-structured and readable test classes following Java best practices.
- Coverage: A summary of the coverage achieved for the tested classes.
Important: Please send me a quick message before placing an order. I like to take a look at the complexity of your classes first

FAQ
Do you need my entire source code?
Not necessarily. If your architecture is well decoupled, you can just send me the specific classes (e.g., the Service and its Model/DTOs) you want me to test, and I can write the tests in isolation.
Do you do Integration Testing (database connection, etc.)?
This specific gig is focused strictly on Unit Testing with Mockito to isolate dependencies. If you need Integration Tests using Testcontainers or an in-memory database like H2, please message me first to discuss a custom offer.
Can you write test for Spring Boot applications?
Yes! I'm very comfortable working within the Spring Boot ecosystem. I can write standard isolated unit tests for your Services or use tools like @WebMvcTest for your Controllers.
