Unit Test Boundary Conditions
giuseppe-trisciuoglio/developer-kitBoundary conditions and edge cases are the tricky inputs that often break code. This skill helps you find and test those limits in Java. You will learn to check minimum and maximum numbers, empty strings, null values, and collection sizes. Use JUnit 5 and AssertJ to write clear tests that catch bugs before they reach users.
Anyone writing Java unit tests can benefit. The patterns cover numeric overflow, floating point precision, and off-by-one errors. Each test checks values just below, at, and just above a boundary. This makes your code more reliable and easier to maintain.
