Unit Test for for SlingServlet

[anasustic]

Hi All

I need to write a UnitTest for a doGet method in a Servlet that extends SlingSafeMethodsServlet. 

This is the doGet method I need to write the UnitTest for and I am not sure how to mock the resource for it:

@Override
protected void doGet(@Nonnull SlingHttpServletRequest request, @Nonnull SlingHttpServletResponse response) throws IOException {
    final JsonResponse jsonResponse = new JsonResponse(response);
    final String title = request.getParameter("title");
    final List<APIResult> locations = LocationFinderUtil.getLocationResultStream(request, searchService)
            .filter(result -> StringUtils.isNotBlank(title) &&
                    (StringUtils.containsIgnoreCase(result.getTitle(), title) || StringUtils.containsIgnoreCase(result.getAdditionalAddress(), title)))
            .map(APIResult::new)
            .collect(Collectors.toList());
    jsonResponse.write(locations);
}

Hi @anasustic ,

For writing Junits for OSGi Code, You can go for Mockito framework and use AEMContext to mock the resources. Or you can use Sling Mocks- https://sling.apache.org/documentation/development/sling-mock.html

Please refer the below links for your reference,

Hi @Hemalatha 

Thanks for the reply. 

I am sorry but these two links are broken:

If I use the AEMContext to mock the resource how do I build it using 

aemContext.build().resource()

Hi @anasustic ,

The links are working. PFA. May be it was blocked if you are using VPN. Kindly check. Understand the Junit samples for servlet. How it has been written and note down the test cases for your servlet based on your use case, then write it by referring the samples is the best way.

Thank you very much @Hemalatha I will research the links from another location. It appears not to work from my current location.

Hi,

check this https://github.com/arunpatidar02/com.aemlab.junitapp/blob/master/core/src/test/java/com/aemlab/junit...

Thanks @arunpatidar 

Your example is clear. I do however build a resource that is a page with several components. I am not sure if I can build a complex resource with context.

[arunpatidar]

Hi,

you can load complex resource from json or create complex resource.
e.g.
