• Go to Travis-ci.com and Sign in with GitHub account
  
• Accept the Authorization of Travis CI
• Click on your profile picture in the top right of your Travis Dashboard, click Settings

• Select the repo you want to use with Travis CI. If repo cannot be found, click Sync account

• Back to Github. Create a .travis.yml file and add the following content(to tell Travis CI what to do), commit and push the changes to the root directory of your repo

  # Building a Java project
  language: java
  
  # We can specify a list of JDKs to be used for testing
  jdk:
   - openjdk11

• Back to Travis CI. Click your repo and you will find it start build by Travis CI

• If the build is successful, you will see a green badge as follows.

• Create the README.md badge(copy the markdown code from Travis CI and paste in the top line of readme.md)

  Travis CI => select your repository => click the build status image => select FORMAT as Markdown => Copy the code of RESULT => paste in the top line of readme.md

• You will see a badge like this in your repo of Github

2. Test

This repo also integrates with Codecov to generate reports.

• Go to the Codecov website and Sign in with GitHub account.

• Accept the authorization of Codecov and add your repository

• Add the following code in the end of .travis.yml file. This is to enable CodeCov's coverage.
  If a build is successful, the code is submitted for coverage analysis

  after_success:
  - bash <(curl -s https://codecov.io/bash)

• Commit and push the changes to your repo, which will trigger a new build in Travis CI

• Create the README.md badge of coverage

  Codecov =>select your repository => Setting => Bedge => Copy the contect of Markdown => paste in readme.md

• You will see the badge like this in your repo

3.Deploy

• Travis CI can help you release to Github after a success build. You will need to provide a Github personal access token(Tutorial: https://docs.github.com/en/gi...
• Now that we have a token go to the project you want to use it with on Travis CI. Then on your project page, go to More options => Settings

• In the Environment Variables section, add variable named GITHUB_TOKEN and use the generated token from Github in previous step

• Travis CI can automatically upload assets to git tags on your GitHub repo. So you need create a tag in your GitHub repo(Tutorial: https://stackoverflow.com/que...
• Add the following to your _.travis.yml_(For more information about parameter configuration, please read https://docs.travis-ci.com/us...

deploy:
  provider: releases
  file_glob: true
  skip_cleanup: true
  api_key: $GITHUB_TOKEN
  file:
    - .travis.yml
  on:
    tags: true
    branch: tag
    repo: <your_github_username>/<your_repo_name>

• Commit and push to trigger a Travis CI build. If the build is successful, you will see .travis.yml in the Releases section of your repo like this

4. Trigger a failed build and notify build result

• Travis CI can notify you about your build results through email, IRC, chat or custom webhooks (https://docs.travis-ci.com/us...

• Add the following to your .travis.yml, which will send the build result to your Email

  notifications:
   email:
  - [e-mail](replace by your e-mail)

• Modify the line 61 of trityp.java(src/main/.../trityp.java) as follows

  triOut = triOut + 2;

• Commit and push to trigger a Travis CI build. As expected, this build will failed and you will receive an Email like this
