Code coverage report ?

[noomerzx]

Any way to see code coverage percentage for tested directory ?

This with included integration when editing file would be great.

I would like to help although i am new to VScode extensions and typescript.
Looking at jacoco, can we do this ?

• code coverage can be enabled from json config.
• prerequisite can be jacoco dependency.
• whenever a UT runs we trigger jacoco command to generate report.
• the output is xml , it can be shown in UI.

Hi @sayonsur,

Thank you for your enthusiasm for this feature. Yes, all kind of contribution is welcome! Let me spend some time to do some investigation for this issue. I'll get back to you when I get some ideas.

Thanks.

Hi @sayonsur, I have some questions:

prerequisite can be jacoco dependency.

Do you mean that we will embedded a jacoco jar in the extension?

the output is xml , it can be shown in UI.

Does that mean that we will parse the xml and show it in the VS Code webview?

[sayonsur]

Hi @jdneo,

I believe it can be achieved in both ways. You can embed the Jacobo jar and programmatically generate code coverage whenever a test is run.
Or we can rely on the jar being present in system and have a configurable path to use it.

It generates a xml . So it can be easily parsed for a web view report. In fact there are many vscode plugins which already parses xml and show report or color code the lines also directly.

The embedded solution looks better since it could avoid breaking changes of the jacoco. But one thing we need to take care is about its license.

BTW, would you like to contribute for this feature?

Hi @jdneo,
I don't have expertise on TS. Although I would love to give it a shot. Is there a timeline ? I might need more time , to understand both the code base and embed jacoco to achieve this.

[jdneo]

Hi @sayonsur, there is no timeline. Just give it a shot whenever you want. If you meet any problem, just feel free to let me know.

[sayonsur]

Sure thing. I will give it a shot and reach out to you in case i need any guidance on the Test project.

@jdneo,

Is there any documentation for the Java test runner ? I don't see any associated test project.
What parameters to pass to debug and check the flow.
Could you please help me out.

Thanks,
Sayon

Hi @jdneo, do we have any updates on the line-by-line code-coverage feature? Thanks in advance.
