I ran the coverage task from Gradle.
Jacco is showing 0% coverage even though 100% of the tests are passing. Can you guide me in the right direction to fix the error?

[anandwana001]

0% are the missed instructions and missed branches. Look for what percentage of lines are covered and try to open the particular file then you will see which line is covered and which line is not covered.

[MaskedCarrot]

generated a coverage report which shows 80% coverage for app package.

@anandwana001 PTAL

[MaskedCarrot]

Jacoco is giving the following results

package	coverage
app	80%
domain	0%
testing	81%
data	0%
utility	0%

[anandwana001]

@MaskedCarrot is this code coverage for the Test package or the main codebase?
Currently, we need to have code coverage for a test package to understand are we covering all the test cases correctly or not.

Also, an additional point if you could try out, After generating a report using Jacoco, try to upload them to codecov and check the result.

@anandwana001 this code coverage is for the main codebase.

Currently, we need to have code coverage for a test package to understand are we covering all the test cases correctly or not.

What I understand is that we have to create a package testPackage with some sample tests and see if jacoco report shows coverage or not.

Closing & reopening to restart now that codecov/codecov-action@v1 has been enabled for actions.

[MaskedCarrot]

@BenHenning just to inform you, this is not the main PR. Peculiar is assigned to this issue I am helping her with this. I talked to her about this and we both are facing the same issue(0 coverage in domain).

[BenHenning]

With the latest re-run I see org.gradle.execution.TaskSelectionException: Task 'testDebugUnitTestCoverage' not found in project ':app'.. Is this using 0.7 or 0.8?

[BenHenning]

Thanks for clarifying @MaskedCarrot. Can we maybe close this issue, then, and consolidate on that PR so that there's a single source of truth?

i also have another pr which I did not open in oppia-android. It ran the action to upload the report to codecov. it has a different task name. I have updated the jacoco_coverage.yml It should work now.

@BenHenning should I close it after the report is uploaded to codecov? Because peculiar has not setup the yml yet.
Also, tests are failing in github action with the same error now.

[MaskedCarrot]

closing this issue. further work on this issue will continue in peculiar's PR

Please I don't understand the issue you are referring here @MaskedCarrot

[MaskedCarrot]

@peculiaruc as per our chats on gitter you said that 100 percent of the tests are passing for the domain module but you are getting 0 percent coverage. This is the issue I am referring here

As I was about getting clearification of your comments. It was a question which I resolved and asked you never mind

[MaskedCarrot]

@peculiaruc okay but I think a pr once referenced cannot be removed.

The issue I mentioned here is for ./gradlew :domain:jacocoTestReport.

You told @BenHenning you are helping but you keep asking me questions as the reviewers. I think you should be providing solutions not just asking me questions.
