Java Software Testing Exercises and Studies

This repository serves as a personal collection of exercises and study materials focused on modern software testing practices in Java.

Used technologies:

• JUnit 5: The primary testing framework for writing and running tests.
• Mockito: The mocking framework used to isolate the code under test by creating mock objects and verifying interactions.
• Assertions: A variety of assertion libraries are used to make test validation more readable and expressive. This includes JUnit's built-in assertions and AssertJ for fluent assertions
• Pitest: A library to generate test mutants, making it possible to check test strengthness and coverage.

Tests Raising

Before almost every exercise, I do some test raising before coding it.

Usually it is a table containing all tests that I thought, like this example:

ID	Input	Expected Output	Was the product updated? (Repository Called)
T3	Product with all non-null valid fields	Empty invalid entries list	Yes, every field
T4	Product with a null name	Empty invalid entries list	Yes, except name
T5	Produto com nome vazio	Invalid entries list with name	Yes, except name
T6	Produto com preço null	Empty invalid entries list	Yes, except price
T7	Produto com preço <= 0	Invalid entries list with price	Yes, except price
etc...	etc...	etc...	etc...

It will probably be in portuguese, but you can find every thought test on the same package where the test class is.
