Using Travis CI on your projects

Okay, so what we have now is a fairly advanced program. 0:01 That's gonna really test some of your skills, 0:07 no I'm just kidding, it's a simple calculator example here. 0:09 And if we just go take a look at the implementation here we look at main. 0:12 Look at the calculator we're gonna see it does some things that you know how to do. 0:16 And if we pop out here it also has tests because you should always write tests. 0:22 Here they are, 0:28 there are some tests, verifies that things are working as they should. 0:28 What I'm gonna do is I'm wanna fork this and 0:33 if you wanna follow along you can too there's a link in the teacher's notes. 0:35 I'm wanna fork this to my own personal account which is what you can do. 0:39 And I'm going to go ahead and I'm going to grab the Clone URL. 0:42 When I pop over to my IntelliJ and I'm gonna check out from Version Control and 0:47 check out from GitHub. 0:51 I have a two factor authentication turned on you might not need this. 0:54 Don't worry about it if you don't see the screen, and now I'm going to go ahead and 0:57 just paste in the URL that I saw you and we're gonna get that down here locally. 1:01 And since it's a great all. 1:06 Should know that's great. 1:07 We're gonna go ahead and click finish. 1:12 And the project is all here and 1:13 we should be able to build. 1:19 If we click here and we do this and we'll go ahead and 1:30 build everything here and if we jump in here and run our Gradle check, 1:34 we'll see that all of our test pass, awesome. 1:38 Okay, so now that it's working. 1:42 Let's go ahead and flip over to our Travis CI, 1:43 and I'm gonna go ahead and click Sync Account. 1:46 Again, I was up here under My Account. 1:50 Now we see that my Java calculator is ready, I'm gonna go ahead and click it. 1:53 Okay, so believe it or not we're all ready now. 1:57 One thing that we need to do is we need to build that .Travis yml 2:01 file that we had discussed. 2:05 And if you come down here to Documentation, 2:07 and you scroll down here, it talks about Language-specific Guides. 2:09 And this is pretty awesome you can see that it does it all for 2:13 all these other languages. 2:14 We're gonna click on the Java one here. 2:16 And the important thing to note here is that 2:19 we're gonna have this language.java and let's just go ahead. 2:21 Let's start that in our IntelliJ. 2:26 We come into here and do a new file called .travis.yml, 2:32 okay that's yml, you had another markup language. 2:37 And we wanna automatically add to get. 2:42 Wanna closer Gradle window here and 2:45 with that said that we needed to do there we'll language Java. 2:46 I'm wanna save that. 2:50 Okay, language Java is what we need. 2:52 It has a really nice default, like if you're running mvn, 2:54 it has automatic things that you would normally do. 2:57 We normally use Gradle here on our courses. 3:00 It's gonna run Gradle check which is the test. 3:02 It also runs Gradle assemble which we saw over there, just kind of working. 3:04 Also if you run ant and there's dependency management and you can test against 3:08 multiple jdk's, and let's go ahead and add the jdk that we specifically want. 3:12 We want the Oracle jdk, right? 3:16 We've been using jdk8. 3:18 Back in our yml file. 3:20 We'll add jdk:. 3:22 And then we'll tab in. 3:27 And this is kinda how you do arrays in this yml language. 3:28 Oraclejdk8. 3:33 Okay. 3:35 That looks good. 3:36 Now what we're gonna do. 3:37 We have our Travis is already set up, I'm gonna go into Version Control here. 3:39 And when we do this push, it should automatically, let's say Setup for 3:44 Travis CI and go ahead and do Commit and Push. 3:51 And we'll go ahead and Push that file in. 3:57 It's gonna go ahead and trigger a build over a Travis. 3:59 Let's take a look and see what's happening. 4:03 If we come back to our home here. 4:05 I have some other repositories that have been running as well and 4:07 I come to My Accounts and I click Java calculator. 4:12 Currently it says there's no build going on let's take a look. 4:16 Under branches here. 4:18 Here it's building it just wasn't showing it just yet. 4:19 This is kind of slick, so what happens? 4:22 Is you get to see what's actually happening. 4:24 You'll see that when it gets into the state where you can actually 4:26 see stuff that pops in over here over my repositories. 4:28 Okay, is going to walk through all of the information down here of what's going on 4:31 in this is again happening because we pushed that file up. 4:36 It's setting up the VM just like it needs. 4:41 This gets faster over time and 4:44 as this this goes up it will start collapsing things for you. 4:46 I'll show you here in a bit after, see it collapsed. 4:50 You have more information here should you need it, but 4:52 it's gonna show you the things that's most interesting to you. 4:55 Here it is, it's running the gradle assemble, it's gonna go ahead and download 4:59 gradle just like somebody might if they didn't have gradle on their system. 5:02 And remember, this is exactly like what you would be doing on your machine. 5:05 But this is happening on the service, you normally wouldn't be watching this. 5:09 Just kinda wanna show off what is happening here. 5:12 All right, it's got gradle installed. 5:15 It's gonna gradle assemble and 5:17 if the build passes which it should because of past locally, right? 5:18 Goes compiling, boom that popped out and then the check happened and 5:22 then when it's all said and done, let's run our test right now. 5:25 After it goes ahead downloads the dependencies, right? 5:30 Boom, build successful. 5:33 It has turned green and now if I look at the Current here, 5:36 it shows me that we have a working build at the moment. 5:39 That's pretty awesome, right? 5:43 I just got an e-mail that had I set this up to connect the slack, 5:46 I also would have got notified in my slack room this is happening. 5:50 Now, one thing that is powerful, and you've probably seen 5:53 these around the internet as you work on open source projects, 5:56 cuz you work on open source projects, right? 5:59 Are these badges. 6:01 If you click on this here you can actually build a new badge. 6:02 We wanna say for the branch master we wanna make sure, 6:05 let's do grab Markdown here. 6:08 Let's go ahead and copy this. 6:10 I'm gonna pop over to my README here. 6:12 I'm gonna add this because I am proud that we know that this is building and 6:15 now anybody can look at this and know that things are working safely. 6:19 It's a good way of showing off that hey things are great here. 6:22 Okay, now if we come back over to our Get repo and when we refresh, 6:27 we'll see this pretty little build passing thing here. 6:30 All right, great. 6:34 Let's go and add some new test so 6:36 we can take a look at what it looks like when you do a poll request. 6:38 Now, the other thing to notice too is that when I push that read me up. 6:41 Look, another log in kicked off, 6:44 like here and see that number two is now going, cool. 6:49
