Hi @anujagrawal699 can you remind me which files the current PR improves test coverage for?

Hi @anujagrawal699 can you remind me which files the current PR improves test coverage for?

I added a test file for features package which has test coverage of 100%.

[XiShanYongYe-Chang]

Before the test file is added, it looks like it's covered by the test, ref https://app.codecov.io/gh/karmada-io/karmada/tree/master/pkg%2Ffeatures

[anujagrawal699]

But a test file was not present in that features package directory. That's the reason i implemented this tests.

[anujagrawal699]

I used go test -coverprofile=coverage.out in pkg/features directory and that returned with 0.0% coverage.

[XiShanYongYe-Chang]

Yes, you're right. Looking at the file alone, there is no test file, but the only method in the file is the init method, which is called when other files use the package.

[XiShanYongYe-Chang]

Hi @anujagrawal699 can we close this pr?

[anujagrawal699]

@XiShanYongYe-Chang Yeah sure.
