GitHub Actions configuration in Selenium Java

Introduction

GitHub Actions lets you automate tasks like testing your code whenever you make changes. It helps catch problems early and saves time.

You want to run Selenium tests automatically when you push Java code to GitHub.

You want to build and test your Java project on different operating systems without manual setup.

You want to get notified if your Selenium tests fail after a code update.

You want to automate deployment steps after tests pass.

You want to share your automation workflow with your team easily.

Syntax

Selenium Java

name: Workflow Name
on: [push, pull_request]
jobs:
  job_id:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Set up JDK
        uses: actions/setup-java@v3
        with:
          distribution: 'temurin'
          java-version: '17'
      - name: Run Selenium tests
        run: |
          ./gradlew test

The name is the workflow's title shown in GitHub.

The on section defines when the workflow runs, like on code push or pull requests.

Examples

This runs tests only when you push code to the repository.

Selenium Java

name: Java Selenium Tests
on: push
jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - uses: actions/setup-java@v3
        with:
          distribution: 'temurin'
          java-version: '17'
      - run: ./gradlew test

This runs tests when a pull request targets the main branch.

Selenium Java

name: Selenium CI
on:
  pull_request:
    branches: [main]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - uses: actions/setup-java@v3
        with:
          distribution: 'temurin'
          java-version: '17'
      - run: ./gradlew test

Sample Program

This workflow runs Selenium tests written in Java automatically on every push or pull request. It checks out the code, sets up Java 17, then runs tests using Gradle.

Selenium Java

name: Selenium Java CI
on: [push, pull_request]
jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Set up JDK 17
        uses: actions/setup-java@v3
        with:
          distribution: 'temurin'
          java-version: '17'
      - name: Run Selenium tests
        run: ./gradlew test

Important Notes

Make sure your Selenium tests can run in a headless mode or use a service like GitHub-hosted browsers.

Use the correct Java version matching your project setup.

Check the Gradle or Maven command matches your build tool.

Summary

GitHub Actions automate running Selenium Java tests on code changes.

Define triggers like push or pull requests to run workflows.

Set up Java and run tests in steps inside the workflow file.

Practice

1. What is the main purpose of a GitHub Actions workflow file in a Selenium Java project?

easy

A. To store test results permanently on GitHub

B. To write Java code for Selenium tests

C. To automate running Selenium Java tests on code changes

D. To manually trigger tests from the command line

Solution

1. Step 1: Understand the role of GitHub Actions workflow

   The workflow file defines automated steps that run on events like code changes.

2. Step 2: Connect workflow to Selenium Java tests

   It automates running Selenium Java tests whenever code is pushed or a pull request is made.

3. Final Answer:

   To automate running Selenium Java tests on code changes -> Option C

4. Quick Check:

   Workflow automates tests = D [OK]

Hint: Workflows automate tasks on code events like push or PR [OK]

Common Mistakes:

• Confusing workflow with writing test code
• Thinking tests run only manually
• Assuming workflow stores test results

2. Which of the following is the correct syntax to specify the Java version in a GitHub Actions workflow step?

easy

A. java-version: 17

B. uses: actions/setup-java@v3
with:
java-version: '17'

C. run: setup-java --version 17

D. setup-java version=17

Solution

1. Step 1: Identify correct action usage syntax

   The official way to set Java version is using 'uses' with 'actions/setup-java@v3' and 'with' parameters.

2. Step 2: Check the correct parameter name and format

   The parameter is 'java-version' with the version as a string, e.g., '17'.

3. Final Answer:

   uses: actions/setup-java@v3 with: java-version: '17' -> Option B

4. Quick Check:

   Correct action syntax = C [OK]

Hint: Use 'uses' with 'actions/setup-java@v3' and 'java-version' key [OK]

Common Mistakes:

• Using 'run' instead of 'uses' for setup-java
• Missing 'with' keyword
• Incorrect parameter name or format

3. Given this GitHub Actions snippet, what will happen when code is pushed to the main branch?

on:
  push:
    branches:
      - main
jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - uses: actions/setup-java@v3
        with:
          java-version: '11'
      - run: mvn test

medium

A. The workflow runs tests using Java 11 on push to main branch

B. The workflow runs tests using Java 17 on any branch push

C. The workflow does not run because 'on' is missing

D. The workflow runs but skips tests

Solution

1. Step 1: Analyze the trigger event

   The workflow triggers on push events to the 'main' branch only.

2. Step 2: Check Java version and test command

   Java 11 is set up, and 'mvn test' runs the tests.

3. Final Answer:

   The workflow runs tests using Java 11 on push to main branch -> Option A

4. Quick Check:

   Push to main triggers tests with Java 11 = B [OK]

Hint: Check 'on' event and Java version in 'setup-java' step [OK]

Common Mistakes:

• Assuming tests run on all branches
• Confusing Java 11 with Java 17
• Ignoring the trigger event

4. Identify the error in this GitHub Actions workflow snippet for running Selenium Java tests:

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - uses: actions/setup-java@v3
        with:
          java-version: 11
      - run: mvn clean test

medium

A. java-version should be a string, e.g., '11'

B. Missing 'on' trigger event

C. The 'run' command should be 'mvn test clean'

D. actions/checkout@v3 is deprecated

Solution

1. Step 1: Check the 'java-version' format

   The 'java-version' parameter must be a string, so it should be '11' with quotes.

2. Step 2: Verify other parts

   Though 'on' is missing, the question focuses on the snippet error; 'mvn clean test' is correct; 'actions/checkout@v3' is current.

3. Final Answer:

   java-version should be a string, e.g., '11' -> Option A

4. Quick Check:

   Java version needs quotes = A [OK]

Hint: Always quote Java version in setup-java 'with' block [OK]

Common Mistakes:

• Using number instead of string for java-version
• Confusing order of mvn commands
• Assuming checkout action is outdated

5. You want to run Selenium Java tests on both push and pull request events, but only for the 'develop' and 'release' branches. Which is the correct 'on' configuration in your GitHub Actions workflow?

hard

A. on:
push:
branches: [develop]
pull_request:
branches: [release]

B. on:
push:
branches: [main]
pull_request:
branches: [main]

C. on:
push:
branches-ignore: [develop, release]
pull_request:
branches-ignore: [develop, release]

D. on:
push:
branches: [develop, release]
pull_request:
branches: [develop, release]

Solution

1. Step 1: Understand event triggers for push and pull_request

   You want both push and pull_request events to trigger on 'develop' and 'release' branches.

2. Step 2: Check correct syntax for multiple branches

   Use 'branches' with a list of branch names under both push and pull_request keys.

3. Final Answer:

   on: push: branches: [develop, release] pull_request: branches: [develop, release] -> Option D

4. Quick Check:

   Push and PR on develop, release branches = A [OK]

Hint: List branches under both push and pull_request keys [OK]

Common Mistakes:

• Using branches-ignore instead of branches
• Triggering on wrong branches like main
• Separating branches for push and pull_request incorrectly
