JUnit Test Assessment

The JUnit test helps assess the skills of candidates before an interview effectively. JUnit is a unit testing framework for Java programming, and it has been crucial in the development of test-driving, collectively known as xUnit. It is designed to check development and programming skills. The test is created and validated by Subject Matter Experts (SMEs).

JUnit test enables employers and recruiters to evaluate candidates' skills and job readiness. For this reason, the emphasis is laid upon evaluating the knowledge of applied skills gained through real work experience rather than theoretical knowledge.
