📝 Walkthrough

Walkthrough

Adds a new unit test class for TimeoutFilter with three test scenarios: fast requests returning 200, slow requests returning 504 Gateway Timeout, and downstream exceptions being rethrown as RuntimeException. Uses Mockito for mocking HttpRequest and FilterChain interactions.

Changes

Cohort / File(s) Summary
TimeoutFilter Unit Tests
src/test/java/org/juv25d/filter/TimeoutFilterTest.java
New test class covering normal fast requests, 504 timeout responses for slow requests (3-second delay), and exception handling when downstream throws IOException.

Poem

🐰 A filter that times out with grace,
Now tested in this code-review space—
Fast paths sprint, slow ones halt,
Exceptions caught (never a fault!)
Our test suite hops forward with glee! ✨

- Line 29: Create a new production class named TimeoutFilter in package
org.juv25d.filter (src/main/java/org/juv25d/filter/) that matches the test's
expectations: implement javax.servlet.Filter (or the project's servlet Filter
interface), perform request handling by executing the filter chain with a
bounded timeout, and if the chain does not complete within the timeout send an
HTTP 504 response and do not continue processing; also provide sensible
init/destroy behavior and a default timeout value so the test instantiating new
TimeoutFilter() compiles and the slow-request test passes.

Create the missing TimeoutFilter class in src/main/java/org/juv25d/filter/ or remove the test.

The TimeoutFilter class does not exist in the production code. Lines 29, 44, and 64 in the test file attempt to instantiate this missing class, which prevents compilation and blocks CI. The test logic itself is sound and expects a filter that implements request timeout handling (returning 504 for slow requests), but the production class must be implemented.
