Openapi-generator: [Java rest-assured] check for “redirect” answer

[jmini]

I have a case, where I need to check if a service is sending a 302 code.
I have generated my client with the java generator, using the rest-assured library.

I was expecting to be able to write something like this:

api.myService().param1Query(“value”).execute(r -> r.thenReturn())
                .then()
                .log().ifValidationFails()
                .assertThat()
                .statusCode(HttpStatus.SC_MOVED_TEMPORARILY)
                .header("Location", "https://example.com/");

This does not work, because by default rest-assured follow the redirect.
I get 200 and the content of https://example.com/.
With Rest-Assured, the solution (1) is to add .redirects().follow(false) after RestAssured.given().

But with the client generated by OpenAPI Generator, it is not possible to access the RequestSpecification created by RestAssured.given() (or I did not find how).

In StoreApiTest.java you will use the generated StoreApi.java (the execute(..) method). This execute(..) creates the RestAssured.given(). But in my test I do not have access to it.

Should the generator be extended to generate two execute methods in order to expose requestSpecification for special cases like mine. Something like this:

public <T> T execute(Function<Response, T> handler) {
    return execute(RestAssured.given(), handler);
}

public <T> T execute(RequestSpecification requestSpecification, Function<Response, T> handler) {
    return handler.apply(requestSpecification.spec(reqSpec.build()).expect().spec(respSpec.build()).when().request(DELETE, REQ_URI));
}

(and the same for executeAs...)

Is there a better solution?

@viclovsky: since you have added the rest-assured library option in swagger-codegen, you might have an opinion on how I should solve my problem.

[viclovsky]

In this case you can use reqSpec() method:

api.myService().param1Query(“value”).reqSpec(r -> r.setConfig(RestAssuredConfig.config().redirect(redirectConfig().followRedirects(false)))
                .then()
                .log().ifValidationFails()
                .assertThat()
                .statusCode(HttpStatus.SC_MOVED_TEMPORARILY)
                .header("Location", "https://example.com/");

Also you can set RequestSpecBuilder in Config like this:

ApiClient.Config myApiConfig = ApiClient.Config
                .apiConfig()
                .reqSpecSupplier(
                        () -> new RequestSpecBuilder().setContentType(JSON)
                                .setConfig(config().objectMapperConfig(objectMapperConfig()
                                        .defaultObjectMapper(gson()))
                                        .redirect(redirectConfig().followRedirects(false)))
                );

and you can customise group requests with method reqSpec:

api.groupApi().reqSpec(r -> r.setConfig(RestAssuredConfig.config().redirect(redirectConfig().followRedirects(false)))).myService().execute(...)

I have tried it, but for the moment it does not work for me. I am using 3.0.7...

---

First approach (.reqSpec(r -> r.build().redirects().follow(false)) in the test case): it did not change anything.

---

Second approach (.addRequestSpecification(..) in the api config): I get a ConnectException. Here the stacktrace:

Hi, Jmini
Sorry for confusing. Yes, it doesn't work cause of my fault — redirecs should be configured via RestAssured configs. For instance,
reqSpec(r->r.setConfig(RestAssuredConfig.config().redirect(redirectConfig().followRedirects(false)))

Please, check again.

[jmini]

Thank you a lot!

This is working for me:

.reqSpec(r -> r.setConfig(RestAssuredConfig.config().redirect(RestAssuredConfig.config().getRedirectConfig().followRedirects(false))))
