How to use github actions bot for testing gradle java - kotlin

Question

I am trying to implement Github-actions(bot), which runs gradle test when PR has been created.
To assure that my workflow file works as I expected, I explicitly wrote a test method which should cause failure.
#Test
fun thisShouldFail() {
assertEquals(1, 2)
}
When I try testing on my local machine, I get the log below.
> Task :test FAILED
FAILURE: Build failed with an exception.
# More
Above log indicates that there was something wrong in the test codes as I expected it to be.
But then Github actions bot runs this command, the test code result is SUCCESS.
Below is my github workflow yaml file for this action.
name: PullRequestGradleTest
on:
pull_request_target:
types: [labeled]
jobs:
test:
name: GradleTest
runs-on: ubuntu-latest
if: contains(github.event.pull_request.labels.*.name, 'STAGING')
steps:
- name: checkout
uses: actions/checkout#v2
- name: Setup JDK 1.8
uses: actions/setup-java#v2
with:
java-version: '8'
distribution: 'adopt'
- name: Grant Permissions to gradlew
run: chmod +x gradlew
- name: Test
run: gradle test --tests "*"
- name: Test Success
if: success()
uses: actions/github-script#0.2.0
with:
github-token: ${{ github.token }}
script: |
const pull_number = "${{github.event.number}}"
await github.pulls.createReview({
...context.repo,
pull_number,
body: "All tests passed.",
event: "APPROVE"
})
- name: Test Fail
if: failure()
uses: actions/github-script#0.2.0
with:
github-token: ${{ github.token }}
script: |
const pull_number = "${{github.event.number}}"
await github.pulls.createReview({
...context.repo,
pull_number,
body: "There is something wrong with test codes.",
event: "REQUEST_CHANGES"
})
await github.pulls.update({
...context.repo,
pull_number,
state: "closed"
})

I found that you are using gradle, not gradlew.
name: PullRequestGradleTest
on:
pull_request_target:
types: [labeled]
jobs:
test:
name: GradleTest
runs-on: ubuntu-latest
if: contains(github.event.pull_request.labels.*.name, 'STAGING')
steps:
- name: checkout
uses: actions/checkout#v2
- name: Setup JDK 1.8
uses: actions/setup-java#v2
with:
java-version: '8'
distribution: 'adopt'
- name: Grant Permissions to gradlew
run: chmod +x gradlew
- name: Test
run: ./gradlew test --tests "*"
- name: Test Success
if: success()
uses: actions/github-script#0.2.0
with:
github-token: ${{ github.token }}
script: |
const pull_number = "${{github.event.number}}"
await github.pulls.createReview({
...context.repo,
pull_number,
body: "All tests passed.",
event: "APPROVE"
})
- name: Test Fail
if: failure()
uses: actions/github-script#0.2.0
with:
github-token: ${{ github.token }}
script: |
const pull_number = "${{github.event.number}}"
await github.pulls.createReview({
...context.repo,
pull_number,
body: "There is something wrong with test codes.",
event: "REQUEST_CHANGES"
})
await github.pulls.update({
...context.repo,
pull_number,
state: "closed"
})
If you use gradle in the command, it will depend on the machine's environment. In this case, there is a possibility that occurs error because of Gradle version. Therefore, you need to use the project's Gradle which is included with your repo. The way to use is using gradlew scripts.
I also recommend following these three steps to test the branch for the pull request.
Clean -> Assemble(or build) -> Test

Base problem was that if we use pull_request_target event, the action runs on the target branch, which would be the base branch that the PR will be merged into. To solve this problem, I had to explicitly set where this action will run on.
On job => steps
steps:
- name: checkout
uses: actions/checkout#v2
with:
ref: ${{ github.event.pull_request.head.ref }}
repository: ${{github.event.pull_request.head.repo.full_name }}
