Chap03 - Product-Composite-Service Tests Not Passing

[lhartmann2]

Hello, In the unit tests for the product-composite-service in Chapter 3, all 3 tests fail with a 'No content - 404 Not Found'. I've even copied the test code verbatim from the source ProductCompositeServiceApplicationTests.java with the same result.

For example on getProductInvalidInput():

GET http://localhost:43167/product-composite/3 accept-encoding: [gzip] user-agent: [ReactorNetty/1.1.3] host: [localhost:43167] WebTestClient-Request-Id: [2] Accept: [application/json]

No content

404 NOT_FOUND Not Found Vary: [Origin, Access-Control-Request-Method, Access-Control-Request-Headers] Content-Type: [application/json] Transfer-Encoding: [chunked] Date: [Tue, 28 Feb 2023 23:20:41 GMT]

{"timestamp":"2023-02-28T23:20:41.406+00:00","status":404,"error":"Not Found","path":"/product-composite/3"}

Status expected:<422 UNPROCESSABLE_ENTITY> but was:<404 NOT_FOUND> Expected :422 UNPROCESSABLE_ENTITY Actual :404 NOT_FOUND

I'm at a loss as to what I'm doing wrong here. Any help is much appreciated. Thank you!

Hello, and thanks for reporting this issue!

Can you change the test-task in the product-composite-service's build.gradle file so that it writes output from the application to the terminal.

The test-task should look like:

tasks.named('test') {
    useJUnitPlatform()

    testLogging {
        outputs.upToDateWhen {false}
        showStandardStreams = true
    }
}

Rerun the test and add a comment to this issue with the output from running the tests with the command:

./gradlew microservices:product-composite:test

Hi Magnus, thank you for the quick reply!

I've updated the build.gradle file as instructed. Here is the output from the test:

Hello again!

I can see that you are using Spring Boot v3.0.3. Since the book is based on v2.5.2, I'm not sure if everything will work out of the box using v3.0.3. But the tests in Chapter 3 should for sure work :-)

Have you compared your code with the code in the book's GitHub repo?

Can you verify that the tests in the GitHub repo works by running the following commands in a temp-folder:

git clone https://github.com/PacktPublishing/Microservices-with-Spring-Boot-and-Spring-Cloud-2E.git
cd Microservices-with-Spring-Boot-and-Spring-Cloud-2E/Chapter03/2-basic-rest-services
./gradlew microservices:product-composite:test

[lhartmann2]

Hi Magnus,

I ran your code in a temp folder and it ran fine.

I then changed the Spring Boot version for all 6 of my projects from 3.0.3 to 2.5.2 (and later 2.7.9) which caused them to suddenly work, so it seems that that was the likely culprit. Although I'm not sure what changed between 2.5.2 (or 2.7.9) and 3.0.3 that everything works except for the tests involving Mockito.

Either way I'm glad that it's now working and I thank you very much for your help!

[magnus-larsson]

Great, happy to help!

I'm closing this issue now.
