Module 14 · Testing Fundamentals

Beyond the 1Z0-830 exam

Testing isn't on the 1Z0-830 — but every lab in this course is a JUnit 5 test, and testing is the core SDET skill. This module is the test author's toolkit: JUnit 5, parameterized tests, test doubles with Mockito, fluent assertions with AssertJ, and the discipline of deterministic tests.

The test author's toolkit. After this module the JUnit-based labs you've been reading will be something you can write — and write so they stay fast, readable, and reliable.
