grailsApplication access in Grails unit Test
- by Reza
I am trying to write unit tests for a service which use grailsApplication.config to do some settings. It seems that in my unit tests that service instance could not access the config file (null pointer) for its setting while it could access that setting when I run "run-app". How could I configure the service to access grailsApplication service in my unit tests.
class MapCloudMediaServerControllerTests {
def grailsApplication
@Before
public void setUp(){
grailsApplication.config=
'''
video{
location="C:\\tmp\\" // or shared filesystem drive for a cluster
yamdi{
path="C:\\FFmpeg\\ffmpeg-20121125-git-26c531c-win64-static\\bin\\yamdi"
}
ffmpeg {
fileExtension = "flv" // use flv or mp4
conversionArgs = "-b 600k -r 24 -ar 22050 -ab 96k"
path="C:\\FFmpeg\\ffmpeg-20121125-git-26c531c-win64-static\\bin\\ffmpeg"
makethumb = "-an -ss 00:00:03 -an -r 2 -vframes 1 -y -f mjpeg"
}
ffprobe {
path="C:\\FFmpeg\\ffmpeg-20121125-git-26c531c-win64-static\\bin\\ffprobe"
params=""
}
flowplayer {
version = "3.1.2"
}
swfobject {
version = ""
qtfaststart {
path= "C:\\FFmpeg\\ffmpeg-20121125-git-26c531c-win64-static\\bin\\qtfaststart"
}
} '''
}
@Test
void testMpegtoFlvConvertor() {
log.info "In test Mpg to Flv Convertor function!"
def controller=new MapCloudMediaServerController()
assert controller!=null
controller.videoService=new VideoService()
assert controller.videoService!=null
log.info "Is the video service null? ${controller.videoService==null}"
controller.videoService.grailsApplication=grailsApplication
log.info "Is grailsApplication null? ${controller.videoService.grailsApplication==null}"
//Very important part for simulating the HTTP request
controller.metaClass.request = new MockMultipartHttpServletRequest()
controller.request.contentType="video/mpg"
controller.request.content= new File("..\\MapCloudMediaServer\\web-app\\videoclips\\sample3.mpg").getBytes()
controller.mpegtoFlvConvertor()
byte[] videoOut=IOUtils.toByteArray(controller.response.getOutputStream())
def outputFile=new File("..\\MapCloudMediaServer\\web-app\\videoclips\\testsample3.flv")
outputFile.append(videoOut)
}
}
