Update: I have changed this question to be about the specific problem I am having. This is because unit testing of Filters will be supported in Grails 2.0 so hopefully the documentation will be better then.
I am trying to write unit tests for the filters I set up to implement Shiro security in my grails app. I am using Grails 1.3.7 and wont be able to use 2.0 for a while (if ever) for this particular project.
The idea behind my filter is that I need to give anonymous access to a number or controller/action combinations but protect access to the others. I also want it to fail safe, i.e. if you forget to explicitly allow access then access is prohibited.
The filter class
class SecurityFilters {
def filters = {
homeAccess(controller: "home", action: "*") {
before = {
// Allow all access
request.accessAllowed = true
}
}
serverAccess(controller: "server", action: "list") {
before = {
// Allow all access
request.accessAllowed = true
}
}
layerAccess(controller: "layer", action: "list|listBaseLayersAsJson|listNonBaseLayerAsJson|showLayerByItsId") {
before = {
// Allow all access
request.accessAllowed = true
}
}
all(uri: "/**") {
before = {
// Check if request has been allowed by another filter
if (request.accessAllowed) return true
// Ignore direct views (e.g. the default main index page).
if (!controllerName) return true
// Access control by convention.
accessControl(auth: false)
}
}
}
}
The Unit tests
import org.codehaus.groovy.grails.plugins.web.filters.FilterConfig
class SecurityFiltersTests extends FiltersUnitTestCase {
protected void setUp() {
super.setUp()
}
protected void tearDown() {
super.tearDown()
}
void testHomeControllerFilter() {
checkFilter('homeAccess')
}
void testServerControllerFilter() {
checkFilter('serverAccess')
}
void testLayerControllerFilter() {
checkFilter('layerAccess')
}
void testAllFilter() {
assertTrue "Write tests", false
}
void checkFilter(String filterName) {
FilterConfig filter = initFilter(filterName)
assertNotNull filterName + " filter should exist", filter
assertExistsBefore(filterName)
assertEquals "accessAllowed should be null to start with", null, filter.request.accessAllowed
// Run filter
filter.before()
assertEquals "accessAllowed should be true now", true, filter.request.accessAllowed
}
}
The Exception
The problem is that when these test are run I get the following exception:
No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.
java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread?

Additionally I have placed the following line in the Unit test:
println "filter.request: " + filter.request
Which prints the following:
filter.request: org.codehaus.groovy.grails.plugins.testing.GrailsMockHttpServletRequest@2914cca4
So it certainly seems to be using a mock request object.
So, the questions.
Am I using FiltersUnitTestCase correctly to execute my filters?
And, if so:
Why am I experiencing this exception?
