Exception assertions

Learn Exception assertions in Groovy through a focused explanation, a dedicated topic-specific example, an engineering boundary, and a mastery check.

12 min read • Advanced

Exception assertions is a focused Groovy lesson inside Concurrency Testing Build. The example uses the construct named in the lesson directly rather than reusing a generic placeholder.

Trace the example from its inputs through Exception assertions and identify the behavior that would change if that construct were removed or replaced. Pay attention to the language-specific rules shown by the syntax, because neighboring lessons intentionally exercise different mechanisms.

Topic-specific example

groovy-0077-cab6ec2f8e.groovy
groovy Try It Live 
def sample78 = [78, 79, 80]
println sample78.sum() // Exception assertions
Edge case / engineering note

For Exception assertions, test one realistic boundary: empty data, invalid input, unavailable resources, lifetime/cleanup, type constraints, or concurrency timing where applicable. A successful happy path is not enough to prove the construct is used correctly.
