WEBVTT 00:00.110 --> 00:00.710 Hi everyone. 00:00.710 --> 00:01.820 Welcome back in this lecture. 00:01.820 --> 00:06.710 What we are going to do is we are going to write a JUnit test that is going to test this rust client. 00:06.740 --> 00:07.100 Okay. 00:07.130 --> 00:11.390 So the very first thing is let's go to the test folder and then check is there a test class already 00:11.390 --> 00:11.960 available. 00:11.960 --> 00:16.820 So if you go to the test folder and if you take a look at the packages, you have a package named HTTP 00:16.910 --> 00:17.600 client. 00:17.600 --> 00:20.570 And here let's open the movie's client test. 00:20.570 --> 00:26.180 So this is a test case which we are going to use in order to test the HTTP client that we had built. 00:26.180 --> 00:28.820 So I'm going to put the movies client on the right. 00:28.850 --> 00:29.630 There you go. 00:29.630 --> 00:32.840 So this is a function which we are going to create the test case for. 00:32.840 --> 00:35.720 So we have an instance of movies client already available. 00:35.720 --> 00:38.390 So now what we are going to do we are going to create a test. 00:38.390 --> 00:40.610 In this case we use our test. 00:40.610 --> 00:44.240 And then the test case name is going to be Get movies by ID. 00:44.480 --> 00:49.490 It can be any name you want, but I'm just going to keep the same name as the actual function. 00:49.490 --> 00:54.920 So in this case we use the movies client dot and then call the get movie by ID. 00:55.160 --> 00:55.490 Okay. 00:55.520 --> 00:58.340 So when you call this function what is the return type of this one. 00:58.370 --> 01:01.340 It's going to be where movie okay. 01:01.370 --> 01:04.400 And then we are going to perform some assertions on it. 01:04.400 --> 01:07.500 So in this case asserts not null. 01:07.530 --> 01:09.390 I believe there is a function like that. 01:09.390 --> 01:12.690 And then we are going to be doing an import of that. 01:12.690 --> 01:15.420 And then after that we are going to be passing the movie instance. 01:15.420 --> 01:19.590 So this is to make sure the movie that is returned by this client is not null. 01:19.590 --> 01:23.640 And after that, what we are going to do, we are going to be looking at some of the properties. 01:23.640 --> 01:26.430 So if you look at the response, what is the response that we are going to get? 01:26.460 --> 01:31.320 So we are going to get this specific response because we are going to be invoking this endpoint, which 01:31.350 --> 01:34.470 actually returns you the movie by ID dot JSON. 01:34.500 --> 01:37.950 And then I want to actually assert on this specific property which is name. 01:37.950 --> 01:42.840 So as long as this assertion succeeds, that means my client is working as expected. 01:42.840 --> 01:46.140 So in this case we can add assert equals. 01:46.140 --> 01:47.910 And then this is a movie name. 01:49.260 --> 01:52.440 And followed by that we are going to pass the movie dot name. 01:52.440 --> 01:55.440 So this is going to perform the assertion on the name. 01:55.650 --> 01:58.350 So now we are going to execute this specific test case. 01:58.350 --> 02:03.870 One thing to quickly call out is that you need to make sure your J-web server is up and running, right. 02:03.900 --> 02:06.000 So if I refresh this, I still get the response. 02:06.000 --> 02:09.060 That means my web server is still up and running. 02:09.090 --> 02:12.450 It is able to provide the response for this specific endpoint call. 02:12.450 --> 02:16.740 So now I'm going to go back to the IntelliJ and then execute this test case. 02:21.510 --> 02:21.960 There you go. 02:21.990 --> 02:23.820 I got a response as expected. 02:23.820 --> 02:26.520 And if you take a look at it we are printing this status code. 02:26.520 --> 02:27.090 Right. 02:27.090 --> 02:30.030 So the status status code value is 200. 02:30.060 --> 02:34.140 That means I was able to communicate with the J-web server that's running in my local. 02:34.170 --> 02:40.230 And then I'm able to also perform the assertion, the value or the name of that specific JSON that is 02:40.230 --> 02:42.330 returned is Batman Begins. 02:42.360 --> 02:42.870 There you go. 02:42.870 --> 02:46.920 We have our very first test case completed for the HTTP client. 02:46.920 --> 02:53.310 So what we have done so far is that we have learned how to build an HTTP client using the new HTTP client 02:53.310 --> 02:54.780 API, which is this one. 02:54.780 --> 03:00.060 And then we were able to assert that by making sure there are proper assertions in place. 03:00.060 --> 03:02.010 In this case, we are asserting the name. 03:02.010 --> 03:07.080 I hope you all were able to follow along and successfully write the HTTP client and the associated test 03:07.110 --> 03:09.570 to make sure this is working as expected. 03:09.600 --> 03:11.130 This marks the end of this lecture. 03:11.130 --> 03:12.180 Thank you for watching.
