One tutorial to cover it all. I take you from nothing, to coding a terminal app, to writing tests, to creating a GitHub repo, to hooking it up, to building a continuous integration workflow, and more. While the analysis and design of a SDLC is important, we won't be going over that here as it would take more work than it's worth for such a simple app.

0:00 Intro
3:14 Install IDE (Eclipse)
3:53 Explanation of the app we're building - Caesars Cipher
4:36 Hop into Eclipse
5:15 Create Gradle project
6:10 Create CaesarsCipher.java class
6:45 How to start actually writing code
7:37 Start coding our cipher method
8:02 Talk about what the cipher method code does
10:17 Start coding our offsetBy method along with what it does
11:37 Create offsetChar method
11:40 Overview of the offsetBy method code
13:24 Start coding our offsetChar method
13:34 Talk about what the offsetChar method code does
14:53 After completing CaesarsCipher, we create the Main class
15:35 Start coding our main method along with what it does (ignore package name... it should be caesars.cipher)
18:00 Run the code
18:13 Write code to actually print out the result
18:25 Run the code again... but mistake
19:03 Fix our code & talk about what it does
19:33 Run our code again again
19:37 Clean up our code
20:15 Walk through all of the code in the order our IDE runs it
25:39 Create CaesarCipherTest.java JUnit test
26:14 Write JUnit tests to test our code
26:38 Talk about what the JUnit test code does
28:10 Run our JUnit tests
28:25 Write a failing test & talk about why tests fail
29:24 Comment out failing test
29:31 Test our tests & ensure our code works
29:57 Create our GitHub repository
30:35 Turn our project into a local Git repository
31:18 Open Git perspective
31:50 Stage our code changes & write commit message
32:06 Hook up your GitHub user to Eclipse
33:33 Commit & Push to our master branch
33:36 Connect our local Git repository to our remote GitHub repository
34:28 Start creating our continuous integration workflow with CircleCI
34:40 Create a CircleCI account here: go.thoughtleaders.io/1419920191121
34:46 Navigate to Add Projects
34:58 Set Up Project for our Caesars Cipher project repo that CircleCI sees on GitHub
35:12 Add dependencies & test in build.gradle for our JUnit 5 (Jupiter) tests
dependencies {
testImplementation 'org.junit.jupiter:junit-jupiter-api:5.3.1'
testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine:5.3.1'
}
test {
useJUnitPlatform()
}
36:26 Stage, Commit, & Push our build.gradle changes
36:46 On CircleCI, click Start Building then Add Config (CircleCI will build a branch for us)
37:15 Check our pipeline and confirm it successfully builds
37:22 A deeper look into our CircleCI pipeline
38:43 A deeper look into what CircleCI did on GitHub
39:11 Compare & pull request our changes from the CircleCI branch to our master branch
39:59 Why we need multiple branches
40:59 Delete our circleci-project-setup branch
41:15 Implement a failing test
41:26 Pull code from our GitHub repo
41:51 Create a new branch in Eclipse
42:12 Commit & Push our failing test to our new branch
42:25 CircleCI is building our code & running our tests
42:43 Our test failed
43:39 We can no longer Merge Pull Request on GitHub
43:55 Outro
