> Key: CAMEL-24772
> URL: https://issues.apache.org/jira/browse/CAMEL-24772
> Project: Camel
> Issue Type: Bug
> Components: camel-jbang
> Affects Versions: 4.23.0
> Reporter: Ricardo Martinez
> Assignee: Claus Ibsen
> Priority: Trivial
>
> h2. Problem
> {{OllamaDoctorSupportTest.detectReturnsNotRunningWhenEndpointUnreachable}}
> fails deterministically on
> any developer machine that has a local Ollama instance listening on the
> default port
> {{localhost:11434}}:
> {code}
> [ERROR] OllamaDoctorSupportTest.detectReturnsNotRunningWhenEndpointUnreachable
> org.opentest4j.AssertionFailedError:
> Expecting value to be false but was true
> at
> OllamaDoctorSupportTest.detectReturnsNotRunningWhenEndpointUnreachable(OllamaDoctorSupportTest.java:49)
> {code}
> It fails on all three surefire attempts (the module sets
> {{rerunFailingTestsCount=2}}), so it is not
> flaky — it is a hard, environment-dependent failure. It passes in CI only
> because CI hosts have no
> Ollama running.
> h2. Root cause
> The test asserts that an unreachable endpoint yields {{running() == false}}:
> {code:java}
> LlmClient client =
> LlmClient.create().withApiType(LlmClient.ApiType.ollama).withUrl("http://127.0.0.1:1";);
> OllamaDoctorSupport.Status status = OllamaDoctorSupport.detect(client);
> assertThat(status.running()).isFalse();
> {code}
> The assumption is that {{withUrl(...)}} pins the client to that URL. It does
> not.
> {{OllamaDoctorSupport.detect(client)}} delegates to
> {{LlmClient.detectEndpoint()}}, which is a
> *discovery* method with deliberate fallbacks:
> {code:java}
> public boolean detectEndpoint() {
> boolean found;
> if (tryExplicitUrl()) { // http://127.0.0.1:1 -> fails,
> nothing is listening
> found = true;
> } else if (apiType != null) {
> found = switch (apiType) {
> ...
> case ollama -> tryInfraOllama() || tryDefaultOllama(); // <--
> falls back to localhost:11434
> };
> }
> ...
> }
> {code}
> So when the explicit URL is unreachable the client falls back to
> {{tryInfraOllama()}} (the
> {{camel infra run ollama}} PID files) and then {{tryDefaultOllama()}}
> ({{http://localhost:11434}}).
> On a host with Ollama running, {{tryDefaultOllama()}} succeeds and
> {{running()}} is correctly
> {{true}}.
> The production behaviour is right — fallback discovery is the whole point of
> a {{camel doctor}}
> probe, and the javadoc says so: _"Probes {{camel infra run ollama}} PID files
> and the default
> {{http://localhost:11434}} endpoint."_ The *test* is what encodes a wrong
> assumption. As written it
> cannot express "unreachable endpoint means not running" on any host, because
> the fallback will always
> be consulted.
> Note the other tests in the same class are not affected: they start a real
> local {{HttpServer}} on an
> ephemeral port and assert {{running() == true}} plus a specific {{baseUrl}},
> which holds regardless of
> host state. Only the negative test is host-dependent.
> h2. How to reproduce
> {code}
> # with Ollama running locally (default port)
> curl -s -o /dev/null -w '%{http_code}\n' http://localhost:11434/ # 200
> mvn test -pl dsl/camel-jbang/camel-jbang-core -Dtest=OllamaDoctorSupportTest
> {code}
> Expected: pass. Actual: {{detectReturnsNotRunningWhenEndpointUnreachable}}
> fails.
> Stopping Ollama makes it pass again.
> h2. Suggested fix
> Test-only change; no production code needs to change.
> Option 1 — skip the assertion when the host itself provides a reachable
> default endpoint. Keeps the
> CI coverage and matches the class's existing "no mocking framework" style:
> {code:java}
> @Test
> void detectReturnsNotRunningWhenEndpointUnreachable() {
> // detectEndpoint() falls back to camel infra / localhost:11434, so this
> case is only
> // meaningful when the host has no Ollama of its own
> assumeFalse(defaultOllamaReachable(), "a local Ollama is running on the
> default port");
> ...
> }
> {code}
> Option 2 — give {{LlmClient}} a package-private seam to disable fallback
> discovery, so the negative
> path can be asserted unconditionally. More thorough, and makes the
> explicit-URL contract testable in
> its own right, at the cost of a small production API addition.
> Option 1 is probably enough. Either way the intent is worth a comment, since
> the next person to read
> the test will make the same assumption.
