Shopper. get('/survey/? pk=4&type=results') If either a knowledge dictionary and a question string within the URL direction are supplied, the knowledge dictionary is used for processing the request and the question string within the URL course is missed. The persist with argument to get may be set to actual so one can train the attempt purchaser to stick with redirects within the reaction. If it does so, a redirect_chain characteristic should be set at the again reaction. This characteristic might be a listing describing the intermediate URLs visited earlier than the tip of the redirect chain. each one aspect within the record should be a tuple containing the intermediate URL course and the prestige code that caused it to be retrieved. ultimately, any additional key-phrase arguments can be utilized to set arbitrary HTTP header values within the request. for instance: reaction = self. customer. get('/', HTTP_USER_AGENT='Tester') This name will set the HTTP_USER_AGENT header within the request to Tester. Returning to our personal try, which gives simply the URL course argument, we will run it now with deal with. py attempt survey. SurveyHomeTest and be sure that up to now every thing seems to be sturdy. we will be able to retrieve the house web page and the reaction comes again with a profitable prestige code. yet what approximately trying out the contents of the web page? we want to ensure that a few of the surveys that are supposed to look are showing, and extra that the 2 surveys within the database that are supposed to now not look at the web page aren't indexed. the particular web page content material lower back is saved within the content material characteristic of the reaction. we will learn this at once, however the Django TestCase classification additionally presents easy methods to fee even if yes textual content seems within the reaction. those equipment are named assertContains and assertNotContains. [ 113 ] Getting Fancier: Django Unit try Extensions to take advantage of the assertContains procedure we go within the reaction and the textual content we're searching for. we will additionally optionally specify a count number of the variety of occasions that textual content should still look. If we specify count number, the textual content needs to seem precisely that repeatedly within the reaction. If we don't specify count number, assertContains easily assessments that the textual content seems at least one time. ultimately, we may perhaps specify the status_code that the reaction must have. If we don't specify this, then assertContains verifies that the prestige code is 2 hundred. The assertNotContains approach takes a similar arguments as assertContains aside from count number. It verifies that the handed textual content doesn't look within the reaction content material. we will be able to use those the way to make certain that the house web page comprises circumstances every one of accomplished, energetic, and Upcoming, and that it doesn't include both Too previous or Too some distance Out. additionally, because those tools money the prestige code, we will be able to get rid of that fee from our personal attempt code. therefore the attempt technique turns into: def testHome(self): from django. middle. urlresolvers import opposite reaction = self. purchaser. get(reverse('survey_home')) self. assertContains(response, "Completed", count=2) self. assertContains(response, "Active", count=2) self. assertContains(response, "Upcoming", count=2) self.
